For example, the expressions of the first switching mode and the second switching mode proposed in the present disclosure can be used interchangeably.

It is further understood that, although the operations are described in a specific order in the drawings in the embodiments of the present disclosure, it should not be understood as requiring the operations to be performed in the specific order shown or in a serial order, or requiring the execution of all the operations shown to obtain the desired results. In certain environments, multitasking and parallel processing may be advantageous.

It should be noted that all actions of acquiring signals, information or data in this application are carried out in compliance with the relevant data protection laws and policies of the country where they are located and with the authorization given by the owner of the corresponding device.

For ease of understanding, the terms involved in the present disclosure are first introduced.

1. Uplink antenna (Tx antenna), subject to the thermal and power consumption limitations of the terminal, the terminal has a limited number of radio frequency (RF) chains for processing and receiving/transmitting signals. For example, the terminal can have two RF links, and the two RF links can be two transmit (Tx) links, two receive (Rx) links, and two transmit links/receive links. In this process, multiple uplink antennas can share one RF link, and one uplink antenna is usually on one frequency band at the same time.

2. Uplink antenna switching (UL Tx switching). When the frequency band of the downlink control information (DCI) sent by the base station is different from the frequency band of multiple uplink services scheduled by the base station, the terminal needs to switch the uplink antenna from the frequency band where the downlink control information is located to the frequency band where multiple uplink services are located. This process can be called uplink antenna switching. For example, version 18 supports switching between two uplink antennas through the following multiple schemes:

Solution 1: Before the terminal switches, the two uplink antennas are in band A and band B respectively. After the terminal switches, the two antennas are in band C and band D respectively. At this time, the terminal has two implementation methods: Method 1: One of the uplink antennas switches from band A to band C, and the other uplink antenna switches from band B to band D. At this time, the switching gap is determined by N{A-C} and N{B-D}; Method 2: One of the uplink antennas switches from band B to band C, and the other uplink antenna switches from band A to band D. At this time, the switching gap is determined by N{B-C} and N{A-D}.

Solution 2: Before the terminal switches, the two uplink antennas are on band A. After the terminal switches, the two antennas are on band C and band D respectively. At this time, N{A-C} and N{A-D} determine the switching gap.

Solution 3: Before the terminal switches, the two uplink antennas are in band A and band B respectively. After the terminal switches, the two antennas are in band C. At this time, the switching gap is determined by N{A-C} and N{B-C}.

3. Sub-Carrier Space (SCS). There are multiple sub-carriers in the carrier signal, and the interval between each sub-carrier is the sub-carrier spacing. An uplink service or a downlink control message is usually transmitted on a frequency band at the same time. A frequency band corresponds to a fixed type of sub-carrier spacing. For example, the sub-carrier spacing of band A is 15KHz, the sub-carrier spacing of band B is 30KHz, and so on.

4. Switch gap: The switching gap can also be called the switching time or switching period. When the terminal switches the uplink antenna from one frequency band to another, there is a switching gap. During the switching gap, the terminal can perform a switching operation on the uplink antenna, and during the switching gap, the base station will not schedule uplink transmission in the frequency band before the uplink antenna is switched and the frequency band after the uplink antenna is switched.

5. Downlink Control Information (DCI): Downlink control information is transmitted on the physical downlink control channel (PDCCH). It is control information related to the physical uplink shared channel (PUSCH) and the physical downlink shared channel (PDSCH). The downlink control information includes resource block allocation information, modulation method and other related content.

In the related art, when the downlink control information sent by the network device and the multiple uplink services scheduled by the network device are in different frequency bands, the terminal needs to perform uplink antenna switching to switch the multiple uplink antennas from the frequency band where the downlink control information is located to the frequency band where the multiple uplink services are located.

However, the switching mode of the multiple uplink antennas may be that the multiple uplink antennas are switched simultaneously, or the multiple uplink antennas are switched separately.

Please refer to FIG. 2, which shows an example of simultaneous switching of two uplink antennas. In FIG. 2, DCI1 and DCI0 are located on band A and band B respectively, and uplink services PUSCH1 and PUSCH0 are located on band C and band D respectively. The starting positions of the two uplink services PUSCH1 and PUSCH0 are the same, both located at T ₀ , that is, the two uplink services start at the same time, N1 is the switching gap required for the terminal to switch the uplink antenna from band A to band C, and N2 is the switching gap for the terminal to switch the uplink antenna from band B to band D. As can be seen from FIG. 2, the time N1 and N2 for the terminal to switch the uplink antenna on the two sets of frequency band pairs are consistent, so the mode of uplink antenna switching performed by the terminal is simultaneous switching, which is regarded as the uplink antenna switching of the two sets of frequency band pairs as one time.

Please refer to FIG. 3 for another example of simultaneous switching of two uplink antennas. The difference from FIG. 3 is that the starting positions of the two uplink services PUSCH1 and PUSCH0 are different. The starting position of PUSCH1 is T _0,2 and the starting position of PUSCH0 is T _0,1 , that is, the two uplink services do not start at the same time. Although the starting positions of the two uplink services are different, the switching gap between the two is The maximum value is selected from N1 and N2, that is, based on PUSCH1, N1 is used as the switching gap for uplink antenna switching of two frequency band pairs, so the uplink antennas of these two frequency band pairs are switched once.

Please refer to FIG. 4 , which shows an example of two uplink antennas being switched separately. In FIG. 4 , the starting positions of the two uplink services PUSCH1 and PUSCH0 are the same, both located at T ₀ . It can be seen from FIG. 4 that the times N1 and N2 at which the terminal performs uplink antenna switching on the two frequency band pairs are different, so the uplink antenna switching mode performed by the terminal is switching separately, and the number of uplink antenna switching times for the two frequency band pairs is regarded as multiple times, and the switching of the uplink antenna on each frequency band pair is an independent switching.

Please refer to Figure 5, which shows another example of switching two uplink antennas separately. The difference between Figure 5 and Figure 4 is that the starting positions of the two uplink services PUSCH1 and PUSCH0 are different. The starting position of PUSCH1 is T _0,2 , and the starting position of PUSCH0 is T _0,1 . At this time, the switching gap N2 of PUSCH1 is based on the starting position T _0,2 of PUSCH1, and the switching gap N1 of PUSCH0 is based on the starting position T _0,1 of PUSCH0. Therefore, the switching gaps N1 and N2 for the terminal to switch the uplink antennas on the two sets of frequency band pairs are also different and independent.

It can be seen that when the terminal's uplink antenna switching mode has at least two different modes, such as one switching and multiple switching, it is necessary to clarify the conditions for the uplink antenna switching mode to ensure that the terminal can better select the uplink antenna switching mode when performing uplink antenna switching.

FIG. 1 is a method for determining an uplink antenna switching mode according to an exemplary embodiment. The method is executed by a user equipment and includes the following steps:

In step S101, at least one downlink control information sent by a network device is received, where the downlink control information is used to schedule a plurality of uplink services for uplink antenna switching.

Among them, the user equipment proposed in any embodiment of the present disclosure can be a mobile phone, a tablet, a portable computer, a computer with wireless transceiver function, a virtual reality (virtual reality (VR)) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in a smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in a smart city (smart city), a wireless terminal in a smart home (smart home), etc. The present disclosure does not limit the application scenario, and the user equipment may sometimes also be referred to as a terminal device, a terminal, an access terminal, a UE unit, a UE station, a mobile device, a mobile station, a mobile station (mobile station), a mobile client, etc. For the convenience of readers, the user equipment will be referred to as a terminal below.

Among them, in some wireless communication systems, uplink communication and downlink communication will be carried out between the terminal and the base station. The uplink communication and downlink communication require transmission resources. If the terminal needs to send data to the base station, the terminal will request uplink resources from the base station. The base station configures the uplink resources in the downlink control information. After the terminal receives the downlink control information, it uses the uplink resources in the downlink control information to schedule the uplink service, and the terminal then sends the uplink service data to the base station through the uplink.

Among them, the user equipment will receive at least one downlink control information sent by the network equipment, and the at least one downlink control information is used to schedule multiple uplink services of the user equipment. When the frequency band where the at least one downlink control information is located is different from the frequency band where the multiple uplink services are located, it is necessary to switch the uplink antenna from the frequency band where the downlink control information is located to the frequency band where the uplink service is located.

For example, when the number of at least one downlink control information is 1, when the frequency band where the downlink control information is located is different from the frequency band where multiple uplink services are located, the uplink antenna needs to be switched from the frequency band where the downlink control information is located to the frequency bands where multiple uplink services are located.

For example, when the number of at least one downlink control information is multiple, and the frequency band where the multiple downlink control information is located is different from the frequency band where the multiple uplink services are located, it is necessary to switch the uplink antenna from the frequency band where the multiple downlink control information is located to the frequency band where the multiple uplink services are located.

In step S102, the uplink antenna switching mode is determined according to the multiple uplink services and/or downlink control information.

The uplink antenna switching modes triggered by multiple uplink services include a first switching mode and a second switching mode.

The first switching mode includes at least one of the following: the user equipment performs an uplink antenna switch once, multiple uplink antenna switches performed by the user equipment are regarded as one, the user equipment performs uplink antenna switching based on a switching gap, the frequency band pair for which the user equipment performs uplink antenna switching shares a switching gap, and multiple uplink antenna switches performed by the user equipment share a switching gap.

The second switching mode includes at least one of the following: the user equipment performs multiple uplink antenna switching, the user equipment performs uplink antenna switching based on multiple switching gaps, the switching gaps of the frequency band pairs for which the user equipment performs uplink antenna switching are independent, and the switching gaps used for multiple uplink antenna switching performed by the user equipment are independent.

Among them, since the frequency band where the downlink control information is located is the frequency band before the uplink antenna switching, and the frequency band where the uplink service is located is the frequency band after the uplink antenna switching, both are related to the uplink antenna switching. Therefore, based on the downlink control information and at least one of the multiple uplink services, it is possible to determine whether the uplink antenna switching mode triggered by the multiple uplink services is the first switching mode or the second switching mode.

For example, the uplink antenna switching mode triggered by the multiple uplink services may be determined according to the multiple uplink services that require uplink antenna switching.

For example, the mode of uplink antenna switching triggered by the multiple uplink services may be determined according to the downlink control information for scheduling the multiple uplink services.

For example, the mode of uplink antenna switching triggered by multiple uplink services may be determined according to multiple uplink services that require uplink antenna switching and downlink control information for scheduling the multiple uplink services.

Through the above technical solution, at least one downlink control information sent by a network device can be received, and the downlink control information is used to schedule multiple uplink services for uplink antenna switching; based on the multiple uplink services and/or downlink control information, the uplink antenna switching mode is determined, which clarifies the conditions under which the uplink antenna switching mode occurs, so as to ensure that the terminal can better select the uplink antenna switching mode when performing uplink antenna switching.

FIG. 11 is a method for determining an uplink antenna switching mode according to an exemplary embodiment, the method being executed by a user equipment, comprising the following steps:

In step S201, it is determined that the downlink control information and the multiple uplink services are located in different frequency bands.

Among them, when the downlink control information sent by the network device is located in the same frequency band as the multiple uplink services scheduled by the network device, it is determined that the multiple uplink services do not need to perform uplink antenna switching; when the downlink control information sent by the network device is located in different frequency bands than the multiple uplink services scheduled by the network device, it is determined that the multiple uplink services need to perform uplink antenna switching to adapt to data reception and transmission on the new frequency band.

For example, the initial states of the two uplink antennas are both in band A, and the antenna states of the two uplink antennas after switching are respectively in band B and band C. That is, the terminal receives the scheduling information of the base station in band A and needs to send uplink services on band B and/or band C.

For example, the initial states of the two uplink antennas are in band A and band B, and the antenna states after switching are in band C and band D, that is, the terminal receives the scheduling information sent by the base station in band A and/or band B, and needs to send uplink services on band C and/or band D.

For example, the initial states of the two uplink antennas are in band A and band B, and the antenna states of the two uplink antennas after switching are both in band C, that is, the terminal receives the scheduling information sent by the base station in band A and/or band B, and needs to send uplink services on band C.

It can be understood that the initial state refers to the state before the uplink antenna is switched, that is, the frequency band where the downlink control information is located; the antenna state refers to the state after the uplink antenna is switched, that is, the frequency band where the uplink service is located. The frequency bands where multiple downlink control information are located can be the same frequency band or different frequency bands, and the frequency bands where multiple uplink services are located can be the same frequency band or different frequency bands.

In step S202, it is determined that the multiple uplink services require uplink antenna switching.

In which, in response to determining that the downlink control information and the multiple uplink services are in different frequency bands, it can be determined that multiple uplink services require uplink antenna switching. At this time, the uplink antenna switching mode can be determined based on multiple uplink services and/or downlink control information.

Through the above technical solution, when the downlink control information sent by the network device and the multiple uplink services scheduled by the network device are in different frequency bands, it is determined that the multiple uplink services need to perform uplink antenna switching; based on the multiple uplink services that need to perform uplink antenna switching and at least one of the downlink control information that schedules the multiple uplink services, the uplink antenna switching mode triggered by the multiple uplink services is determined, which clarifies the conditions under which the uplink antenna switching mode occurs, so as to ensure that the terminal can better select the uplink antenna switching mode when performing uplink antenna switching.

FIG. 12 is a method for determining an uplink antenna switching mode according to an exemplary embodiment. The method is executed by a user equipment and includes the following steps:

In step S301, it is determined that the multiple uplink services start simultaneously.

The simultaneous start of multiple uplink services includes at least one of the following:

Aligning first symbols of channels carrying the multiple uplink services;

The number of symbols spaced between first symbols of the channels carrying the multiple uplink services is less than or equal to a predetermined value.

In step S302, it is determined that the uplink antenna switching mode is the first switching mode.

Among them, the first switching mode includes at least one of the following: the user equipment performs an uplink antenna switch once, multiple uplink antenna switches performed by the user equipment are regarded as one, the user equipment performs uplink antenna switching based on a switching gap, the frequency band pair for the user equipment to perform uplink antenna switching shares a switching gap, and multiple uplink antenna switches performed by the user equipment share a switching gap.

Among them, when multiple uplink services that require uplink antenna switching do not start at the same time, if the uplink antenna switching mode triggered by multiple uplink services is determined as the first switching mode, on the one hand, it will cause the base station to be unable to schedule uplink transmission on some frequency bands in a timely manner; on the other hand, it places high requirements on terminal capabilities; on the third hand, the protocol needs to define reference points for multiple uplink antennas to share switching gaps, which is more complicated for the protocol.

For example, please refer to Figure 3, in which DCI1 and DCI0 are located on band A and band B respectively, and uplink services PUSCH1 and PUSCH0 are located on band C and band D respectively, and the starting positions of the two uplink services PUSCH1 and PUSCH0 are different, the starting position of PUSCH1 is T _0,2 , and the starting position of PUSCH0 is T _0,1 , that is, the two uplink services do not start at the same time, N1 is the time required for the terminal to switch the uplink antenna from band A to band C, and N2 is the time required for the terminal to switch the uplink antenna from band B to band D. MAX(N1, N2) represents selecting the maximum value from N1 and N2 as the switching gap between the two uplink antennas. MAX(N1, N2) shown in Figure 3 is N1.

When the two uplink services start at different times, it means that the actual switching gaps required for the uplink antennas on the two frequency band pairs are different. For example, the switching gap required for the band A and band C frequency band pair is longer than that required for the band B and band D frequency band pair. At this time, if the switching gap for the uplink antenna switching is determined to be N1, the switching of the two uplink antennas is performed according to N1, which results in the switching gap N1 of the uplink antenna on the band B and band D frequency band pair being increased compared to the actually required switching gap N2. During this increased duration, the base station cannot schedule uplink transmission on band B and band D.

Therefore, in order to avoid the above three situations, the present disclosure proposes that when multiple uplink services requiring uplink antenna switching start at the same time, the uplink antenna switching mode triggered by multiple uplink services is determined to be the first switching mode.

For example, please refer to Figure 2, in which DCI1 and DCI0 are located on band A and band B respectively, and uplink services PUSCH1 and PUSCH0 are located on band C and band D respectively, and the starting positions of the two uplink services PUSCH1 and PUSCH0 are the same, both located at T ₀ , that is, the two uplink services start at the same time, N1 is the time required for the terminal to switch the uplink antenna from band A to band C, and N2 is the time required for the terminal to switch the uplink antenna from band B to band D.

As can be seen from Figure 2, since the two uplink services start at the same time, the switching gaps N1 and N2 actually required for the two frequency band pairs are the same. At this time, if the switching gap for uplink antenna switching is determined to be N1 or N2, the two frequency band pairs will release band A, band B, band C and band D at the same time after the switching gap N1 or N2, and there will be no situation where the base station cannot schedule uplink transmission on some frequency bands in a timely manner.

Through the above technical solution, when multiple uplink services requiring uplink antenna switching start at the same time, the uplink antenna switching mode triggered by the multiple uplink services is determined to be the first switching mode.

On the one hand, since the present disclosure determines the switching mode of the uplink antenna as the first switching mode when multiple uplink services that require uplink antenna switching start at the same time, rather than determining the switching mode of the uplink antenna as the first switching mode when multiple uplink services do not start at the same time, the switching gaps actually required by multiple uplink antennas are consistent, and multiple uplink antennas are switched based on the consistent switching gaps, which can also avoid the situation where the base station cannot schedule uplink transmission in some frequency bands in a timely manner. On the second hand, for the first switching mode, the terminal only needs to determine one switching gap, and its determination logic is relatively simple, and the requirements for the terminal are relatively low. On the third hand, the protocol does not need to define reference points for switching multiple uplink antennas, which reduces the complexity of the protocol.

FIG. 13 is a method for determining an uplink antenna switching mode according to an exemplary embodiment. The method is executed by a user equipment and includes the following steps:

In step S401, the first symbol alignment of the channel carrying the multiple uplink services is determined.

The alignment of the first symbols of the channels carrying the multiple uplink services may be regarded as the multiple uplink services starting simultaneously.

The symbol may be an OFDM symbol in a time-frequency resource concentration, and the channel carrying multiple uplink services is a transmission resource. The terminal may use the transmission resource to send data of the uplink service to the base station to realize uplink transmission.

It can be understood that the first symbol of the channel carrying multiple uplink services proposed in any embodiment of the present disclosure is the first symbol of the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) occupied by the uplink services.

The first symbol alignment of the channels carrying the multiple uplink services includes at least one of the following:

When the subcarrier spacing of the frequency bands where multiple uplink services are located is the same, if the first symbols of the channels carrying the multiple uplink services overlap in the time domain, it is regarded that the first symbols of the channels carrying the multiple uplink services are aligned.

When the number of uplink services is two and the subcarrier spacings of the frequency bands where the two uplink services are located are different, the first symbol of the channel on the frequency band with a small subcarrier spacing overlaps with the first symbol of the channel on the frequency band with a large subcarrier spacing in the time domain and is regarded as being aligned with the first symbol of the channel carrying the multiple uplink services.

When there are multiple uplink services and the subcarrier spacings of the frequency bands where the multiple uplink services are located are different, the first symbol of the channel carrying the first uplink service overlaps with the first symbol of the channel carrying the last uplink service in the time domain. The first symbol of the channel considered to carry the multiple uplink services is aligned.

Wherein, when the subcarrier spacing of the frequency bands where multiple uplink services are located is the same, the first symbols of the channels carrying multiple uplink services overlap in the time domain, including at least one of the following (1) and (2):

(1) The left edges of the first symbols of the channels carrying multiple uplink services are aligned, which can be regarded as the alignment of the first symbols of the channels carrying multiple uplink services.

(2) The right edges of the first symbols of the channels carrying multiple uplink services are aligned, which can be regarded as the alignment of the first symbols of the channels carrying multiple uplink services.

It can be understood that any multiple embodiments of the present disclosure may be understood to include two or more.

In step S402, it is determined that the uplink antenna switching mode is the first switching mode.

Herein, step S402 may refer to the above step S302 and will not be described in detail here.

Through the above technical solution, when the first symbols of the channels carrying multiple uplink services are aligned, the uplink antenna switching mode triggered by multiple uplink services can be determined as the first switching mode.

FIG. 14 is a method for determining an uplink antenna switching mode according to an exemplary embodiment. The method is executed by a user equipment and includes the following steps:

In step S501, the subcarrier spacings of the frequency bands where two uplink services are located are different, and the first symbol of the channel on the frequency band with a small subcarrier spacing overlaps with the first symbol of the channel on the frequency band with a large subcarrier spacing in the time domain.

Among them, when the number of uplink services is two and the subcarrier spacings of the frequency bands where the two uplink services are located are different, the first symbol of the channel on the frequency band with a small subcarrier spacing overlaps with the first symbol of the channel on the frequency band with a large subcarrier spacing in the time domain, which is regarded as the alignment of the first symbols of the channels carrying multiple uplink services.

Among them, when the subcarrier spacing of the frequency bands where multiple uplink services are located is different, the symbol lengths of the channels on the frequency bands with different subcarrier spacings are different. The larger the subcarrier spacing, the shorter the length of the corresponding channel symbol. For example, when the subcarrier spacing is 15Khz, the symbol length is 66.7us, and when the subcarrier spacing is 30KHz, the symbol length is 33.3us, etc.

Among them, when the number of subcarrier spacings is two, the first symbol of the channel on the frequency band with a small subcarrier spacing overlaps with the first symbol of the channel on the frequency band with a large subcarrier spacing in the time domain, including at least one of the following (3), (4), (5), and (6). For the convenience of description, in the following multiple examples, the first symbol of the channel on the frequency band with a small subcarrier spacing is referred to as symbol A, and the first symbol of the channel on the frequency band with a large subcarrier spacing is referred to as symbol B. Symbol A and symbol B are only a description method for the convenience of readers, and are not used as a limitation on the first symbol of the channel on the frequency band with a small subcarrier spacing and the first symbol of the channel on the frequency band with a large subcarrier spacing.

(3) The left edge of the first symbol of the channel in the frequency band with a small subcarrier spacing is aligned with the left edge of the first symbol of the channel in the frequency band with a large subcarrier spacing.

For example, please refer to Figure 6, when the left edge of symbol A (subcarrier spacing is 15KHz) and the left edge of symbol B (subcarrier spacing is 30KHz) are aligned at the dotted line 10, there is an overlapping area of symbol B between symbol A and symbol B.

(4) The right edge of the first symbol of the channel in the frequency band with a small subcarrier spacing is aligned with the right edge of the first symbol of the channel in the frequency band with a large subcarrier spacing.

For example, please refer to Figure 7, when the right edge of symbol A (subcarrier spacing is 15KHz) and the right edge of symbol B (subcarrier spacing is 30KHz) are aligned at the dotted line 20, there is an overlapping area of symbol B between symbol A and symbol B.

(5) The left edge of the first symbol of the channel in the frequency band with a small subcarrier spacing is aligned with the right edge of the first symbol of the channel in the frequency band with a large subcarrier spacing.

For example, please refer to Figure 8, when the left edge of symbol A (subcarrier spacing is 15KHz) and the right edge of symbol B (subcarrier spacing is 30KHz) are aligned at the dotted line 30, there is an overlapping area between symbol A and symbol B, which is the left edge of symbol A or the right edge of symbol B, that is, the overlapping area where the dotted line 30 is located.

(6) The right edge of the first symbol of the channel in the frequency band with a small subcarrier spacing is aligned with the left edge of the first symbol of the channel in the frequency band with a large subcarrier spacing.

For example, please refer to Figure 9, when the right edge of symbol A (subcarrier spacing is 15KHz) and the left edge of symbol B (subcarrier spacing is 30KHz) are aligned at the dotted line 40, there is an overlapping area between symbol A and symbol B, the right edge of symbol A or the left edge of symbol B, that is, the overlapping area where the dotted line 40 is located.

From (3) and (4), it can be seen that when there are two uplink services, if the first symbols of the channels on the frequency band with the subcarrier spacing of the two uplink services are aligned on the left or right, the two uplink services can be regarded as starting at the same time.

It can be seen from (5) and (6) that if, in the subcarrier spacing where the two uplink services are located, the left edge of the first symbol of the channel on the frequency band with a smaller subcarrier spacing is aligned with the right edge of the first symbol of the channel on the frequency band with a larger subcarrier spacing, although the left edge of the first symbol of the channel on the frequency band with a smaller subcarrier spacing differs from the left edge of the first symbol of the channel on the frequency band with a larger subcarrier spacing by a symbol of the channel on the frequency band with a larger subcarrier spacing, the two can also be regarded as aligned.

If, in the subcarrier spacing where two uplink services are located, the right edge of the first symbol of the channel on the frequency band with a small subcarrier spacing is aligned with the left edge of the first symbol of the channel on the frequency band with a large subcarrier spacing, although the left edge of the first symbol of the channel on the frequency band with a small subcarrier spacing differs from the left edge of the first symbol of the channel on the frequency band with a large subcarrier spacing by a symbol of the channel on the frequency band with a small subcarrier spacing, the two can also be regarded as aligned.

In step S502, it is determined that the uplink antenna switching mode is the first switching mode.

Here, step S502 may refer to the above step S302 and will not be described in detail here.

Through the above technical solution, when the subcarrier spacings of the two frequency bands where the uplink services are located are different, if the first symbol of the channel on the frequency band with a small subcarrier spacing overlaps with the first symbol of the channel on the frequency band with a large subcarrier spacing in the time domain, it can be determined that the switching mode is the first switching mode.

FIG. 15 is a method for determining an uplink antenna switching mode according to an exemplary embodiment, the method being executed by a user equipment, comprising the following steps:

In step S601, it is determined that a first symbol of a channel carrying a first uplink service among the multiple uplink services overlaps with a first symbol of a channel carrying a last uplink service in the time domain.

Among them, when the number of uplink services is multiple and the subcarrier intervals of the multiple uplink services are different, the first symbol of the channel carrying the first uplink service among the multiple uplink services overlaps with the first symbol of the channel carrying the last uplink service in the time domain, which can be regarded as the alignment of the first symbols of the channels carrying multiple uplink services.

Among them, the first symbol of the channel carrying the first uplink service among the multiple uplink services overlaps with the first symbol of the channel carrying the last uplink service in the time domain, including at least one of the following (7), (8), (9), and (10), the following multiple uplink services are data sent from different frequency bands arranged in sequence, and the first uplink service can be sent from the terminal before the last uplink service. Then, when the first symbol of the channel carrying the first uplink service overlaps with the symbol of the channel carrying the last uplink service in the time domain, it can be considered that the first symbol of the channel carrying the uplink service between the first uplink service and the last uplink service is also aligned with the first symbol of the channel carrying the first uplink service and the symbol of the channel carrying the last uplink service.

(7) A left edge of a first symbol of a channel carrying the first uplink service is aligned with a left edge of a first symbol of a channel carrying the last uplink service.

For example, taking the case where multiple uplink services including the first uplink service (the first uplink service), the second uplink service and the third uplink service (the last uplink service) are sent from the terminal in sequence, when the left edge of the first symbol of the channel carrying the first uplink service is aligned with the left edge of the first symbol of the channel carrying the third uplink service, then the left edge of the first symbol of the channel carrying the second uplink service located between the first uplink service and the third uplink service is also aligned.

(8) The right edge of the first symbol of the channel carrying the first uplink service is aligned with the right edge of the first symbol of the channel carrying the last uplink service.

For example, taking the case where multiple uplink services including the first uplink service (the first uplink service), the second uplink service and the third uplink service (the last uplink service) are sent from the terminal in sequence, when the right edge of the first symbol of the channel carrying the first uplink service is aligned with the right edge of the first symbol of the channel carrying the third uplink service, then the right edge of the first symbol of the channel carrying the second uplink service located between the first uplink service and the third uplink service is also aligned.

(9) The left edge of the first symbol of the channel carrying the first uplink service is aligned with the right edge of the first symbol of the channel carrying the last uplink service.

For example, taking the case where multiple uplink services including the first uplink service (the first uplink service), the second uplink service and the third uplink service (the last uplink service) are sent from the terminal in sequence, when the left edge of the first symbol of the first uplink service is aligned with the right edge of the first symbol of the channel carrying the third uplink service, then the left edge or right edge of the first symbol of the channel carrying the second uplink service located between the first uplink service and the third uplink service is also aligned.

(10) The right edge of the first symbol of the channel carrying the first uplink service is aligned with the left edge of the first symbol of the channel carrying the last uplink service.

For example, a plurality of uplink services including a first uplink service (the first uplink service), a second uplink service and a third uplink service (the last uplink service) are sent from a terminal in sequence. When the right edge is aligned with the left edge of the first symbol of the channel carrying the third uplink service, the left edge or right edge of the first symbol of the channel carrying the second uplink service located between the first uplink service and the third uplink service is also aligned.

Among them, due to the different terminal capabilities, when the terminal capability is strong, the first symbol of the channel carrying multiple uplink services can be aligned. When the first symbol of the channel carrying multiple uplink services is aligned, it can be regarded as that multiple uplink services that require uplink antenna switching start at the same time.

In step S602, it is determined that the uplink antenna switching mode is the first switching mode.

Here, step S602 may refer to the above step S302 and will not be described in detail here.

Through the above technical solution, when there are multiple uplink services and the subcarrier intervals of the multiple uplink services are different, the first symbol of the channel carrying the first uplink service overlaps with the first symbol of the channel carrying the last uplink service in the time domain and is regarded as the first symbol alignment of the channels carrying multiple uplink services. In this way, the uplink antenna switching mode can be determined as the first switching mode, so that the terminal determines that the uplink antenna switching mode triggered by multiple uplink services is the first switching mode.

FIG. 16 is a method for determining an uplink antenna switching mode according to an exemplary embodiment. The method is executed by a user equipment and includes the following steps:

In step S701, it is determined that the number of symbols spaced between first symbols of the channel carrying multiple uplink services is less than or equal to a predetermined value.

If the number of symbols between the first symbols of the channel carrying multiple uplink services is less than or equal to a predetermined value, it is considered that multiple uplink services can start simultaneously.

The predetermined value is a threshold value of the number of symbols between the first symbol of a channel on a set reference frequency band and the first symbol of channels on other frequency bands.

The predetermined value N is predefined by the standard, or configured by the base station to the terminal, or reported by the terminal to the base station. The value of N can be 1, 2, 3, 4, 5, 6, 7..., and the present disclosure does not limit this.

Among them, due to different terminal capabilities, the first symbols of channels carrying multiple uplink services can be aligned. When the first symbols of channels carrying multiple uplink services are aligned, it can be regarded that multiple uplink services requiring uplink antenna switching start at the same time; in the case of other terminal capabilities, there is no need to align the first symbols of channels carrying multiple uplink services. If the number of symbols between the first symbols of channels carrying multiple uplink services is less than or equal to a predetermined value, it can also be regarded as that multiple uplink services requiring uplink antenna switching start at the same time.

For example, please refer to Figure 10, taking the number of multiple uplink services as two as an example, when the subcarrier spacing of the frequency bands where the two uplink services are located is different, the first symbol of the channel on the 15KHz frequency band and the first symbol of the channel on the 30KHz frequency band are separated by one symbol of the uplink service on the 15KHz frequency band, or are separated by two symbols of the uplink service on the 30KHz frequency band. In this case, although there is a certain number of symbols between the two symbols, it is also considered that the two uplink services start at the same time.

Among them, the reference frequency band can have different types of subcarrier spacing such as 15KHz, 30KHz, 60KHz, 120KHz, 240KHz, etc. When determining the number of symbols between the first symbol of the channel on the reference frequency band and the first symbol of the channels on the remaining frequency bands, the number of symbols between the first symbols of the channels carrying multiple uplink services should be determined according to the reference frequency band, that is, the number of symbols between the first symbol of the channel on the reference frequency band and the first symbol of the channels on the remaining frequency bands should be determined according to the reference frequency band. It can be understood that the reference frequency band is defined by the standard, or configured by the base station to the terminal, or reported by the terminal to the base station.

For example, please refer to the frequency band with a subcarrier spacing of 30KHz and the frequency band with a subcarrier spacing of 15KHz shown in FIG10. If the reference frequency band is the frequency band with the maximum subcarrier spacing (the frequency band of 30KHz), at this time, the left edge of the first symbol of the channel on the 15KHz frequency band and the left edge of the first symbol of the channel on the 30KHz frequency band are separated by two symbols of the channel on the 30KHz frequency band. Of course, FIG10 is only an example. When the reference frequency band is the frequency band with a subcarrier spacing of 30KHz, the number of symbols between the left edges of the two first symbols should be at least two. In the case where the reference frequency band is the frequency band with the maximum subcarrier spacing (the frequency band of 30KHz), the predetermined value N can also be set with the frequency band with the maximum subcarrier spacing as a reference.

For example, please refer to FIG10. If the reference frequency band is a frequency band with the minimum subcarrier spacing (a frequency band of 15KHz), the left edge of the first symbol of the channel on the 15KHz frequency band and the left edge of the first symbol of the channel on the 30KHz frequency band are separated by one symbol of the channel on the 15KHz frequency band. Of course, FIG10 is only an example. When the reference frequency band is a frequency band with a subcarrier spacing of 15KHz, the number of symbols between the left edges of the two first symbols should be at least one. In the case where the reference frequency band is a frequency band with the minimum subcarrier spacing (a frequency band of 15KHz), the predetermined value N can also be set with the frequency band with the minimum subcarrier spacing as a reference.

Among them, the frequency band corresponding to the maximum subcarrier spacing mentioned above can also be called when there are only two frequency bands in all frequency bands. The frequency band corresponding to the large subcarrier spacing. The frequency band corresponding to the minimum subcarrier spacing mentioned above can also be called the frequency band corresponding to the small subcarrier spacing when there are only two frequency bands.

The reference frequency band may also be set to the frequency band corresponding to the highest frequency point. When there are only two frequency bands, the frequency band corresponding to the highest frequency point may also be referred to as the frequency band corresponding to the higher frequency point. The reference frequency band may also be set to the frequency band corresponding to the lowest frequency point. When there are only two frequency bands, the frequency band corresponding to the lowest frequency point may also be referred to as the frequency band corresponding to the lower frequency point.

In step S702, it is determined that the uplink antenna switching mode is the first switching mode.

Among them, taking the predetermined value N as an example, when the number of symbols spaced between the first symbols of the channel carrying multiple uplink services is less than or equal to N, the uplink antenna switching mode triggered by the multiple uplink services is determined to be the first switching mode.

Here, step S702 may refer to the above step S302 and will not be described in detail here.

Through the above technical solution, when the number of symbols spaced between the first symbols of the channel carrying multiple uplink services is less than or equal to a predetermined value of symbols, the uplink antenna switching mode triggered by multiple uplink services can be determined as the first switching mode, so that the terminal can better select the uplink antenna switching mode.

FIG. 17 is a method for determining an uplink antenna switching mode according to an exemplary embodiment. The method is executed by a user equipment and includes the following steps:

In step S801, it is determined that the first symbols of the channels carrying the multiple uplink services are aligned, and the number of symbols spaced between the first symbols of the channels carrying the multiple uplink services is less than or equal to a predetermined value.

Among them, determining that the first symbols of the channels carrying the multiple uplink services are aligned and the number of symbols between the first symbols of the channels carrying the multiple uplink services is less than or equal to a predetermined value can be regarded as the simultaneous start of multiple uplink services.

Among them, the alignment of the first symbol of the channel carrying multiple uplink services can refer to the above-mentioned step S401, which will not be repeated here; the number of symbols between the first symbols of the channel carrying multiple uplink services is less than or equal to the predetermined value, which can refer to the above-mentioned step S701, which will not be repeated here.

In step S802, it is determined that the uplink antenna switching mode is the first switching mode.

Here, step S802 may refer to the above step S302 and will not be described in detail here.

Through the above technical solution, when the first symbols of the channels carrying multiple uplink services are aligned and the number of symbols between the first symbols of the channels carrying multiple uplink services is less than or equal to a predetermined value, the uplink antenna switching mode triggered by multiple uplink services can be determined as the first switching mode, so that the terminal can better select the uplink antenna switching mode.

FIG. 18 is a method for determining an uplink antenna switching mode according to an exemplary embodiment. The method is executed by a user equipment and includes the following steps:

In step S901, it is determined that a plurality of uplink services are not started at the same time.

The multiple uplink services not starting at the same time include at least one of the following:

The first symbols of the channels carrying the multiple uplink services are not aligned;

The number of symbols spaced between first symbols of the channels carrying the multiple uplink services is greater than a predetermined value.

In step S902, it is determined that the uplink antenna switching mode is the second switching mode.

Among them, the second switching mode includes at least one of the following: the user equipment performs multiple uplink antenna switching, the user equipment performs uplink antenna switching based on multiple switching gaps, the switching gaps of the frequency band pairs for the user equipment to perform uplink antenna switching are independent, and the switching gaps used for the multiple uplink antenna switching performed by the user equipment are independent.

Among them, when multiple uplink services that require uplink antenna switching start at the same time, if the uplink antenna switching mode triggered by the multiple uplink services is determined as the second switching mode, the terminal will need to determine multiple switching gaps, while if multiple uplink services start at the same time, only one switching gap needs to be determined. The determination of multiple switching gaps will result in a waste of terminal computing resources.

For example, please refer to Figure 4, in which DCI1 and DCI0 are located on band A and band B respectively, and uplink services PUSCH1 and PUSCH0 are located on band C and band D respectively, and the starting positions of the two uplink services PUSCH1 and PUSCH0 are the same, both are T ₀ , and the two uplink services start at the same time, N1 is the time required for the terminal to switch the uplink antenna from band A to band C, and N2 is the time required for the terminal to switch the uplink antenna from band B to band D.

When two uplink services start at the same time, it means that the switching gaps actually required for the uplink antennas on the two frequency band pairs are the same. At this time, if the switching mode is determined to be the second switching mode, two switching gaps are used to switch the two uplink antennas respectively. The amount of data calculated is small, which does not match the computing resources allocated by the terminal, which undoubtedly occupies excess computing resources of the terminal.

In order to reduce the waste of terminal computing resources, the present disclosure proposes that when multiple uplink services for which uplink antenna switching is to be performed do not start at the same time, the mode of uplink antenna switching triggered by the multiple uplink services is determined to be the second switching mode.

For example, please refer to Figure 5, where DCI1 and DCI0 in Figure 5 are located on band A and band B, respectively, and uplink services PUSCH1 and PUSCH0 are located on band C and band D, respectively, and the starting positions of the two uplink services PUSCH1 and PUSCH0 are different, the starting position of PUSCH1 is T _0,2 , and the starting position of PUSCH0 is T _0,1 , that is, the two uplink services do not start at the same time, N1 is the time required for the terminal to switch the uplink antenna from band A to band C, and N2 is the time required for the terminal to switch the uplink antenna from band B to band D.

In the case where the two uplink services are not started at the same time, the switching gap actually required for the uplink antenna on the band A and band C frequency pair is N1, and the switching gap actually required for the band B and band D frequency pair is N2. The switching gaps actually required for the two are different. At this time, the switching mode is determined to be the second switching mode, and two switching gaps are used to switch the two uplink antennas respectively. The amount of data calculated is larger, which can match the computing resources allocated by the terminal, so that the computing resources of the terminal are fully utilized and there is no waste of computing resources. In addition, the switching gap between the uplink antenna on the band A and band C frequency pair does not affect the switching gap between the uplink antenna on the band B and band D frequency pair. The two are independent of each other. After the switching gap N2 between the band B and band D frequency pair, the base station can immediately schedule band B and band D without having to wait until N1 to schedule band B and band D.

Through the above scheme, when multiple uplink services that require uplink antenna switching do not start at the same time, the uplink antenna switching mode triggered by the multiple uplink services is determined to be the second switching mode. On the one hand, the computing resources of the terminal can be matched with the calculated data, and the computing resources of the terminal can be fully utilized without wasting computing resources; on the other hand, when multiple uplink services do not start at the same time, multiple switching gaps are used to switch multiple uplink antennas respectively, which also makes the switching processes of multiple uplink antennas independent of each other, and the base station can schedule the released frequency band in time.

FIG. 19 is a method for determining an uplink antenna switching mode according to an exemplary embodiment. The method is executed by a user equipment and includes the following steps:

In step S1001, it is determined that the first symbols of the channels carrying multiple uplink services are not aligned, and/or the number of intervals between the first symbols of the channels carrying multiple uplink services is greater than a predetermined value.

Determining that the first symbols of channels carrying multiple uplink services are not aligned and/or the number of intervals between the first symbols of channels carrying multiple uplink services is greater than a predetermined value can be regarded as that the multiple uplink services do not start at the same time.

In some implementations, the first symbol of the channel carrying the multiple uplink services is not aligned, including at least one of the following:

When the subcarrier spacing of the frequency bands where multiple uplink services are located is the same, if the first symbols of the channels carrying the multiple uplink services do not overlap in the time domain, it is regarded that the first symbols of the channels carrying the multiple uplink services are not aligned.

When the number of uplink services is two and the subcarrier spacings of the frequency bands where the two uplink services are located are different, the first symbol of the channel on the frequency band with a small subcarrier spacing does not overlap with the first symbol of the channel on the frequency band with a large subcarrier spacing in the time domain, and is regarded as the first symbol of the channel carrying the multiple uplink services is not aligned.

When there are multiple uplink services and the subcarrier spacings of the frequency bands where the multiple uplink services are located are different, the first symbol of the channel carrying the first uplink service does not overlap with the first symbol of the channel carrying the last uplink service in the time domain, which can be regarded as the first symbols of the channels carrying the multiple uplink services are not aligned.

Wherein, when the subcarrier spacing of the frequency bands where multiple uplink services are located is the same, the first symbols of the channels carrying multiple uplink services do not overlap in the time domain, including at least one of the following (1) and (2):

(1) The left edges of the first symbols of the channels carrying multiple uplink services are not aligned, which can be regarded as the first symbols of the channels carrying multiple uplink services are not aligned.

(2) The right edges of the first symbols of the channels carrying multiple uplink services are not aligned, which can be regarded as the first symbols of the channels carrying multiple uplink services are aligned.

In some implementations, taking the predetermined value as N as an example, when the number of symbols spaced between the first symbols of the channels carrying multiple uplink services is greater than N, it is determined that the mode of uplink antenna switching triggered by the multiple uplink services is the second switching mode. It can be understood that the predetermined value is a threshold value of the number of symbols spaced between the first symbol of the channel on the reference frequency band and the first symbol of the channel on the remaining frequency bands.

The predetermined value N is predefined by a standard, or configured by a base station to a terminal, or reported by a terminal to a base station.

The number of symbols spaced between the first symbols of channels carrying multiple uplink services is defined according to a reference frequency band. The reference frequency point is either defined by a standard, or configured by a base station to a terminal, or reported by a terminal to a base station.

The reference frequency band may be a frequency band corresponding to the maximum subcarrier spacing, or a frequency band corresponding to the minimum subcarrier spacing, or a frequency band corresponding to the highest frequency point, or a frequency band corresponding to the lowest frequency point. The frequency band corresponding to the maximum subcarrier spacing is When there are only two frequency bands, it can also be called the frequency band corresponding to the large subcarrier spacing. When there are only two frequency bands, the frequency band corresponding to the minimum subcarrier spacing can also be called the frequency band corresponding to the small subcarrier spacing. When there are only two frequency bands, the frequency band corresponding to the highest frequency point can also be called the frequency band corresponding to the higher frequency point. When there are only two frequency bands, the frequency band corresponding to the lowest frequency point can also be called the frequency band corresponding to the lower frequency point.

In step S1002, it is determined that the uplink antenna switching mode is the second switching mode.

Among them, the step S1002 refers to the above-mentioned step S902 and will not be repeated here.

Through the above technical solution, the uplink antenna switching mode triggered by multiple uplink services can be determined as the second switching mode when at least one of the first symbols of the channels carrying multiple uplink services are not aligned and the number of intervals between the first symbols of the channels carrying multiple uplink services is greater than a predetermined value.

FIG. 20 is a method for determining an uplink antenna switching mode according to an exemplary embodiment. The method is executed by a user equipment and includes the following steps:

In step S1101, it is determined that a first symbol of a channel carrying a first uplink service among the multiple uplink services does not overlap with a first symbol of a channel carrying a last uplink service in the time domain.

Among them, when the subcarrier spacings of the frequency bands where the two uplink services are located are different, the first symbol of the channel on the frequency band with a small subcarrier spacing does not overlap with the first symbol of the channel on the frequency band with a large subcarrier spacing in the time domain, including at least one of the following:

In the two subcarrier spacings, the left edge of the first symbol of the channel on the frequency band with a smaller subcarrier spacing is not aligned with the left edge of the first symbol of the channel on the frequency band with a larger subcarrier spacing;

In two subcarrier spacings, the right edge of the first symbol of the channel on the frequency band with a smaller subcarrier spacing is not aligned with the right edge of the first symbol of the channel on the frequency band with a larger subcarrier spacing;

In the two subcarrier spacings, the left edge of the first symbol of the channel on the frequency band with a smaller subcarrier spacing is not aligned with the right edge of the first symbol of the channel on the frequency band with a larger subcarrier spacing;

In the two subcarrier spacings, the right edge of the first symbol of the channel on the frequency band with a smaller subcarrier spacing is not aligned with the left edge of the first symbol of the channel on the frequency band with a larger subcarrier spacing.

In step S1102, it is determined that the uplink antenna switching mode is the second switching mode.

Through the above technical solution, when the subcarrier spacings of the two frequency bands where the uplink services are located are different, if the first symbol of the channel on the frequency band with a small subcarrier spacing does not overlap with the first symbol of the channel on the frequency band with a large subcarrier spacing in the time domain, it can be determined that the switching mode is the second switching mode.

FIG. 21 is a method for determining an uplink antenna switching mode according to an exemplary embodiment. The method is executed by a user equipment and includes the following steps:

In step S1201, it is determined that a first symbol of a channel carrying a first uplink service among the multiple uplink services does not overlap with a first symbol of a channel carrying a last uplink service in the time domain.

The first symbol of the channel carrying the first uplink service among the multiple uplink services does not overlap with the first symbol of the channel carrying the last uplink service in the time domain, including at least one of the following:

Among multiple uplink services, the left edge of the first symbol of the channel carrying the first uplink service is not aligned with the left edge of the first symbol of the channel carrying the last uplink service;

Among multiple uplink services, the right edge of the first symbol of the channel carrying the first uplink service is not aligned with the right edge of the first symbol of the channel carrying the last uplink service;

Among multiple uplink services, the left edge of the first symbol of the channel carrying the first uplink service is not aligned with the right edge of the first symbol of the channel carrying the last uplink service;

Among multiple uplink services, the right edge of the first symbol of the channel carrying the first uplink service is not aligned with the left edge of the first symbol of the channel carrying the last uplink service.

In step S1202, it is determined that the uplink antenna switching mode is the second switching mode.

Through the above technical solution, when the first symbol of the channel carrying the first uplink service among multiple uplink services and the first symbol of the channel carrying the last uplink service are used, the uplink antenna switching mode triggered by multiple uplink services is determined to be the second switching mode.

FIG. 22 is a diagram showing a method for determining an uplink antenna switching mode according to an exemplary embodiment. The method is performed by a user equipment Execution, including the following steps:

In step S1301, it is determined whether multiple downlink control information are aligned.

The aligning of multiple downlink control information for scheduling multiple uplink services includes at least one of the following (13, (14), and (15):

(13) When the subcarrier spacing of the frequency bands where multiple downlink control information are located is the same, if at least one of the following conditions exists, the multiple downlink control information is regarded as aligned:

Aligning the first symbol of a channel carrying multiple downlink control information;

Aligning the last symbol of a channel carrying multiple downlink control information;

The last symbol of the channel carrying the first downlink control information among the multiple downlink control information is aligned with the first symbol of the channel carrying the last downlink control information;

A first symbol of a channel carrying first downlink control information among multiple downlink control information is aligned with a last symbol of a channel carrying last downlink control information.

(14) When there are two uplink services and the subcarrier spacings of the frequency bands where the two multiple downlink control information are located are different, if the following conditions exist, the multiple downlink control information are regarded as aligned:

The first symbol of the channel carrying downlink control information on the frequency band with small subcarrier spacing overlaps in the time domain with the second symbol of the channel carrying downlink control information on the frequency band with large subcarrier spacing. The first symbol is the first symbol or the last symbol of the channel carrying downlink control information on the frequency band with small subcarrier spacing, and the second symbol is the first symbol or the last symbol of the channel carrying downlink control information on the frequency band with large subcarrier spacing.

(15) When there are multiple uplink services and the subcarrier spacings of the frequency bands where the multiple downlink control information are located are different, if the following conditions exist, the multiple downlink control information are regarded as aligned:

The third symbol of the channel carrying the first downlink control information among the multiple downlink control information is aligned with the fourth symbol of the channel carrying the last downlink control information, wherein the third symbol is the first symbol or the last symbol of the channel carrying the first downlink control information, and the fourth symbol is the first symbol or the last symbol of the channel carrying the last downlink control information.

It can be understood that the first symbol or the last symbol of the channel carrying downlink control information proposed in any embodiment of the present disclosure may be the first symbol or the last symbol of the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) occupied by the downlink control information.

In step S1302, it is determined that the uplink antenna switching mode is the first switching mode.

Through the above technical solution, when multiple downlink control information for scheduling multiple uplink services are aligned, the uplink antenna switching mode triggered by the multiple uplink services is determined to be the first switching mode. On the one hand, since the present disclosure determines the uplink antenna switching mode as the first switching mode when there are multiple downlink control information, rather than determining the uplink antenna switching mode as the first switching mode when multiple downlink control information are not aligned, the switching gaps actually required for multiple uplink antennas are consistent, and multiple uplink antennas are switched based on consistent switching gaps, which can also avoid the situation where the base station cannot schedule uplink transmission in some frequency bands in a timely manner. On the other hand, for the first switching mode, the terminal only needs to determine one switching gap, and its determination logic is relatively simple, and the requirements for the terminal are relatively low. On the third hand, the protocol does not need to define reference points for switching multiple uplink antennas, which reduces the complexity of the protocol.

In step S2002, it is determined that the uplink antenna switching mode is the second switching mode.

Among them, step S2002 can refer to the above-mentioned step S902 and will not be repeated here.

Through the above technical solution, the switching mode can be determined to be the second switching mode when the third symbol of the channel carrying the first downlink control information among multiple downlink control information does not overlap with the fourth symbol of the channel carrying the last downlink control information in the time domain, so that the terminal can better select the uplink antenna switching mode.

FIG30 is a method for determining an uplink antenna switching mode according to an exemplary embodiment. The method is executed by a user equipment and includes the following steps:

In step S2101, it is determined that the downlink control information of the multiple uplink services is the same downlink control information.

In step S2102, it is determined that the uplink antenna switching mode is the first switching mode.

In which, when the downlink control information for scheduling multiple uplink services is the same downlink control information, or multiple downlink control information for scheduling multiple uplink services are regarded as the same downlink control information, the mode of switching multiple uplink antennas can be determined to be the first switching mode.

It is understandable that one downlink control information can schedule multiple uplink services. Therefore, when the downlink control information scheduling multiple uplink services is the same downlink control information, it can be determined that the uplink antenna switching triggered by the multiple uplink services is the first switching mode.

Through the above technical solution, when the downlink control information for scheduling multiple uplink services is the same downlink control information, or multiple downlink control information for scheduling multiple uplink services are regarded as the same downlink control information, the uplink antenna switching mode triggered by multiple uplink and downlink services can be determined to be the first switching mode, so that the terminal can better select the switching mode of the uplink antenna.

FIG. 31 is a method for determining an uplink antenna switching mode according to an exemplary embodiment. The method is executed by a user equipment and includes the following steps:

In step S2201, during the process of switching the uplink antenna from the frequency band where the downlink control information is located to the frequency band where the uplink service is located, the user equipment does not expect the network equipment to perform uplink transmission scheduling on the target frequency band, and the target frequency band is a frequency band that is not concurrent with the frequency band where the uplink service is located, and/or a frequency band that is not concurrent with the frequency band where the downlink control information is located.

Among them, the standard supports configuring related frequency bands for each frequency band, and the frequency band supports concurrency with related frequency bands. When the frequency band is in a switching state, although the base station cannot schedule uplink transmission on the frequency band, it can schedule uplink transmission on the related frequency band; of course, the frequency band can also be not configured with related frequency bands, and does not support concurrency with any frequency band. When the frequency band is in a switching state, the base station cannot schedule uplink transmission on the frequency band, nor can it schedule uplink transmission on any frequency band.

It can be understood that when the frequency band does not support concurrency with any frequency band, the target frequency band is any frequency band; when the frequency band does not support concurrency with some frequency bands, the target frequency band is some frequency bands.

For example, taking the terminal supporting four frequency bands, band A, band B, band C, and band D, if band C is not concurrent with any frequency band or band C is not configured with any related frequency bands, and the two uplink antennas are on Band A and band B respectively before switching, and are on band C after switching, the terminal does not expect the base station to perform uplink transmission scheduling on band D.

It is understandable that when band A, band B, and band C are in the switching state, the terminal does not expect the base station to schedule uplink transmission on band A, band B, and band C to avoid errors in the process of uplink antenna switching between different frequency bands.

Through the above technical solution, in the process of switching the uplink antenna from the frequency band where the downlink control information is located to the frequency band where the uplink service is located, if the frequency band where the uplink service is located does not support concurrency with the target frequency band, or the frequency band where the downlink control information is located does not support concurrency with the target frequency band, the user equipment does not expect the network equipment to perform uplink transmission scheduling on the target frequency band.

FIG. 32 is a method for determining an uplink antenna switching mode according to an exemplary embodiment. The method is executed by a user equipment and includes the following steps:

In step S2301, when the uplink antenna switches from the frequency band where the downlink control information is located to the frequency band where the uplink service is located, the user equipment does not expect the network equipment to perform uplink transmission scheduling on any frequency band, wherein the frequency band where the downlink control information is located is not concurrent with any frequency band.

In the case where the frequency band does not support concurrency with any frequency band, the terminal does not expect the network device to perform uplink transmission scheduling on any frequency band.

Through the above technical solution, in the process of switching the uplink antenna from the frequency band where the downlink control information is located to the frequency band where the uplink service is located, if the frequency band where the uplink service is located does not support concurrency with any frequency band, or the frequency band where the downlink control information is located does not support concurrency with any frequency band, the user equipment does not expect the network equipment to perform uplink transmission scheduling on any frequency band.

FIG. 33 is a method for determining an uplink antenna switching mode according to an exemplary embodiment. The method is executed by a network device and includes the following steps:

In step S2401, when a network device has multiple switching gaps, it is determined that the network device is switched according to the maximum switching gap.

The switching gap may also be called a switching path. If the base station assumes that the terminal switches according to the minimum switching gap, the base station may start scheduling the uplink service of the terminal, but the uplink service of the terminal has not yet been switched to the frequency band where the uplink service should be located.

For example, the initial states of the two uplink antennas are band A and band B, and the antenna states of the two uplink antennas after switching are band C and band D respectively. The switching gap required for one uplink antenna to switch from band A to band C is N1, and the switching gap required for the other uplink antenna to switch from band B to band D is N2. N1 is greater than N2. At this time, if the base station assumes that the terminal switches the uplink antenna according to N2, the base station will start scheduling the uplink services on band A and band C of the terminal, but the uplink antenna of the terminal has not yet switched from band A to band C.

Therefore, the present disclosure assumes that the terminal performs switching according to the maximum switching gap when the terminal has multiple switching gaps.

For example, the initial states of the two uplink antennas are band A and band B, and the antenna states of the two uplink antennas after switching are band C and band D respectively. The switching gap required for one uplink antenna to switch from band A to band C is N1, and the switching gap required for the other uplink antenna to switch from band B to band D is N2. N1 is greater than N2. At this time, the base station will assume that the terminal switches the uplink antenna according to N1. After the switching gap N1, band A has switched to band C, and band B has also switched to band D. In this way, it can be guaranteed that the base station will schedule the uplink services on band A and band C only after the uplink antenna is switched from band A to band C.

Through the above technical solution, when a network device has multiple switching gaps, it is determined that the network device is switched according to the maximum switching gap, which can ensure that the base station will schedule the released frequency band only after the uplink antenna has completed switching on different frequency bands.
