The uplink transmission method provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings through some embodiments and application scenarios thereof.

As shown in fig. 3, an uplink transmission method provided in the embodiments of the present application includes, but is not limited to, the following steps:

step 31: the terminal sends first information to the network side equipment, wherein the first information is used for indicating the interval time required by the antenna switching process.

The interval may also be referred to as a delay (delay). The interval time required for the antenna switching process indicated by the first information is as follows: the maximum one of the interval times required for the antenna switching process under different uplink transmission power requirements and/or peak-to-average ratio requirements. The interval time required for the antenna switching process includes the switch switching and power switching interval times. Specifically, the antenna switching process may include a switch switching process and a power switching process, taking antenna y as an example for switching to antenna x, the antenna switching process includes the whole process of adjusting PA power from a normal transmission power to an off state, adjusting the antenna switching switch state, and adjusting PA power from the off state to the normal transmission state. Accordingly, the interval time required for the antenna switching process indicated by the first information is the total time for completing the switching process and the power switching process. In this embodiment of the present application, the first information may indicate the interval time required for the antenna switching process in an explicit manner, or may indicate the interval time required for the antenna switching process in an implicit manner.

Optionally, the uplink transmission power requirement is determined by uplink power control sent by the network side device; and/or the requirement of the uplink peak-to-average ratio is determined by parameters such as an adjusting mode of uplink scheduling sent by the network side equipment.

Step 32: and the terminal receives the uplink transmission scheduling information sent by the network side equipment.

The uplink transmission scheduling information is used to schedule uplink transmission of the terminal, i.e. uplink transmission scheduling resources of the terminal, or is called as uplink transmission scheduling resources for the terminal. Uplink transmissions include, but are not limited to: a Physical Random Access Channel (PRACH), a Physical Uplink Shared Channel (PUSCH), a Physical Uplink Control Channel (PUSCH), a Sounding Reference Signal (SRS), and the like. The uplink transmission scheduling information may be used for scheduling uplink transmission resources on different antennas for the terminal, or scheduling uplink transmission resources on the same antenna.

Step 33: and when the uplink transmission resource scheduled by the uplink transmission scheduling information meets the interval time requirement indicated by the first information, the terminal performs uplink transmission according to the uplink transmission scheduling information.

If the uplink transmission scheduling information is scheduled by uplink transmission resources on the same antenna, taking fig. 1 as an example, the terminal is scheduled to transmit PUSCH/PUCCH and SRS on antenna x. When the transmission power of the PUSCH/PUCCH and the SRS is different, the first information can also be used for indicating the required interval time of the power switching process between different uplink transmissions, such as the time required for switching the PUSCH/PUCCH transmission power to the SRS transmission power. Then, if the interval time requirement indicated by the first information is met between the PUSCH/PUCCH transmission scheduled by the uplink transmission scheduling information and the SRS transmission, the PUSCH/PUCCH and the SRS are transmitted according to the uplink transmission scheduling information.

If the uplink transmission scheduling information is scheduled for uplink transmission resources on different antennas, taking fig. 1 as an example, the terminal is scheduled to transmit PUSCH/PUCCH on antenna y and SRS on antenna x. Then, if the interval time requirement indicated by the first information is satisfied between the PUSCH/PUCCH transmission scheduled by the uplink transmission scheduling information and the SRS transmission, the PUSCH/PUCCH and the SRS are transmitted according to the uplink transmission scheduling information.

It should be noted that, the sending of the PUSCH/PUCCH first and then the SRS is only used as an exemplary illustration, and a scenario of sending the SRS first and then sending the PUSCH/PUCCH may also be adopted in the transmission scheme in the embodiment of the present application.

In some embodiments of the present application, the first information may include a target capability level, the target capability level being one of a plurality of capability levels, each capability level corresponding to a respective interval time. Optionally, the first information may be terminal capability information, and the terminal reports the interval time required by the antenna switching process to the network side device by using the target capability level carried by the terminal capability information.

In some embodiments of the present application, the target capability level may also be referred to as a target scheduling level, where the target scheduling level is used to assist the network side device in performing uplink transmission scheduling. The target scheduling level is one of a plurality of scheduling levels, and each scheduling level corresponds to a respective interval time. Optionally, the first information may be terminal auxiliary information, and the terminal reports the interval time required by the antenna switching process to the network side device by using the terminal auxiliary information to carry the target scheduling level. It is worth to be noted that the capability level and the scheduling level may be interchanged in some scenarios, and in the embodiment of the present application, the capability level is merely used as an exemplary illustration, and the implementation manner of the scheduling level may also be an implementation manner of the capability level.

The unit of the interval time corresponding to the capability level may be milliseconds (ms), slots (slots), symbols (symbols), and the like. That is, the interval time corresponding to the capability level may include: 0, 1 or more ms/slots/symbols.

Further, the interval time corresponding to each of the plurality of capability levels is related to subcarrier Spacing (SCS). For example, the number of symbols included in the interval time corresponding to one capability level may be different for different SCS.

The system can support a plurality of capability levels, and the interval time corresponding to different capability levels is not identical. The embodiment of the present application takes 2 capability levels as an example for illustration, where the multiple capability levels include a first capability level and a second capability level, and an interval time corresponding to the first capability level is less than an interval time corresponding to the second capability level. Taking the unit of the interval time as the time domain symbol as an example, the interval time corresponding to the first capability level includes 0 or 1 time domain symbol, and the interval time corresponding to the second capability level includes 1 or more time domain symbols. For example, the UE feeds back first information to the base station, where the first information may be UE capability or UE assistance information, and the first information indicates a delay capability level when an antenna of the UE transmitting the SRS is different from an antenna of the PUSCH or PUCCH. The delay capability is divided into a capability level 1 and a capability level 2, and the delay required by the capability level 1 is smaller than that of the capability level 2. The time delay can be related to the SCS, and the time delay is not consistent under different SCSs. Taking the delay as an OFDM symbol level, the delay may include one or more OFDM symbols and the delay is not more than 5 OFDM symbols. Wherein the OFDM symbols include CP-OFDM and DFD-S-OFDM.

The implementation of the first information is introduced above, and the above method is applicable to a single carrier scenario or a scenario without considering carrier influence. The following embodiment of the present application will further describe an implementation manner of the first information under multiple carriers.

In a Carrier Aggregation (CA) or Dual-Connectivity (DC) operating mode, the plurality of capability levels respectively correspond to an interval time on a CA frequency band combination or a DC frequency band combination. The plurality of capability levels correspond to the interval time on one CA band combination or one DC band combination respectively. In addition, the plurality of capability levels corresponding to different CA frequency band combinations or different DC frequency band combinations may also be different.

Optionally, the interval time on the CA frequency band combination or the DC frequency band combination is related to SCS corresponding to the CA frequency band combination or the DC frequency band combination. Where SCS may be different on different carriers, the spacing time on a certain CA frequency band combination or DC frequency band combination is determined based on the smallest or largest SCS within the frequency band combination.

Since SCS on different carriers may be different, the interval time required for the antenna switching process indicated by the first information needs to consider not only the processing time of antenna switching but also the alignment problem of different carriers, and therefore, the interval time on the CA frequency band combination or the DC frequency band combination may include one or more time slots.

In the above step 33, a processing manner that the uplink transmission resource scheduled by the uplink transmission scheduling information meets the interval time requirement indicated by the first information is introduced, and in the following, a processing manner of the terminal when the uplink transmission resource scheduled by the uplink transmission scheduling information does not meet the interval time requirement indicated by the first information is further introduced in this embodiment of the present application.

In some embodiments of the present application, when an uplink transmission resource scheduled by uplink transmission scheduling information does not meet an interval time requirement indicated by first information, a terminal does not respond to a transmission indication of a network side device on a first resource in the uplink transmission resource, where the first resource is a resource that does not meet the interval time requirement indicated by the first information. Since the interval time has an influence on scheduling, the interval time may be regarded as uplink and downlink scheduling limitation for the UE, that is, the UE does not need to accept any related PDCCH/PDSCH/PUCCH/PUSCH transmission requirements within the interval time range. In other words, if the network side device, through scheduling or configuration, makes the UE make a request for corresponding PDCCH/PDSCH/PUCCH/PUSCH transmission in a time including a symbol in the interval time, the UE may choose not to respond to the scheduling. It should be noted that this method is also applicable to the same antenna transmission scenario, and if the network side device allows the UE to make the requirement of the corresponding PDCCH/PDSCH/PUCCH/PUSCH transmission within the time including the symbol within the power switching interval time through scheduling or configuration, the UE may also choose not to respond to the scheduling. It is worth pointing out that, in a CA or DC scenario, when the scheduling information sent by the base station does not meet the interval time requirement indicated by the first information, the terminal does not accept either uplink scheduling or downlink scheduling.

Optionally, when the uplink transmission at least includes an SRS and at least one of a PUSCH, a PUCCH, or a PRACH, and at least one of the following conditions is met, the UE preferentially selects to abandon the SRS transmission:

a. PUSCH/PUCCH transmission corresponding to higher priority, namely, the priority sequence number corresponding to the PUSCH/PUCCH transmission is more than or equal to 1;

b. corresponding to an uplink transmission comprising any one of:

a) ACK-NACK feedback for HARQ processes

b) Scheduling requests

c) Channel Rank indication

d) SSB or CSI-RS resource sequence number indication

e) Uplink physical layer random access channel

c. If the SRS is the SRS transmitted periodically or semi-statically, but the PUSCH or PUCCH comprises the aperiodic CSI feedback information.

Optionally, when none of the above conditions is met, the UE selects to abandon PUSCH or PUCCH transmission.

Or when the uplink transmission resource scheduled by the uplink transmission scheduling information does not meet the interval time requirement indicated by the first information, the terminal performs uplink transmission according to the uplink transmission scheduling information. The scenario may be regarded that the network side device may ignore the first information and autonomously schedule the terminal, and the terminal performs corresponding transmission according to the scheduling. In an alternative, the network side device, through scheduling or configuration, makes the UE perform corresponding PDCCH/PDSCH/PUCCH/PUSCH transmission requirements in a time including a symbol in the interval time, and the terminal needs to perform corresponding transmission in the interval time according to the scheduling, but may ignore the power requirement of the network side device.

The uplink transmission in the embodiment of the present application includes: one of a PUSCH transmission, a PUCCH transmission, and an SRS transmission. And under the condition that the uplink transmission corresponding to the antenna switching process comprises SRS transmission, the antenna port of the transmitting antenna of the SRS transmission is different from that of the transmitting antenna of the PUSCH transmission or the PUCCH transmission, and the required interval time between the SRS transmission and the PUSCH transmission or the PUCCH transmission is positioned on 0 or 1 or more OFDM symbols before or after the SRS transmission. When the uplink transmission corresponding to the antenna switching process includes two SRS transmissions, antenna ports of transmitting antennas of the two SRS transmissions are different, and a required interval between the two SRS transmissions is 0 or 1 or more OFDM symbols.

Optionally, the first information may also be used to indicate a maximum time interval, before and after the SRS, when the UE transmits the SRS and needs to perform antenna switching, at which the UE can be scheduled to uplink; or, when the UE transmits the SRS and needs to perform antenna switching, the maximum value of the UE power switching time before and after the SRS.

Taking the first information as the capability information as an example, the uplink transmission method of the embodiment of the present application includes: the UE transmits capability information to the network indicating the difference in delay capability when the UE transmits SRS on an antenna different from that of PUSCH or PUCCH. The network side equipment configures SRS and PUSCH/PUCCH resources for the UE based on the UE capability, and when the delay reported by the UE is small, the interval between the SRS and the PUSCH/PUCCH resources configured by the network side equipment for the UE is preferably less than or equal to 0 or 1 predefined length, such as the length of a CP or 0 OFDM symbol; if the reported delay is large, the interval configured by the network side device is greater than 1 predefined length, for example, at least one OFDM symbol. In particular, the delay represents the uplink and downlink scheduling limitation for the UE, i.e. within the delay range, the UE does not need to accept any relevant PDCCH/PDSCH/PUCCH/PUSCH transmission requirements. In other words, if the network side device, through scheduling or configuration, makes the UE make a request for corresponding PDCCH/PDSCH/PUCCH/PUSCH transmission in the time including the symbol in the delay, the UE may choose not to respond.

Taking the first information as the auxiliary information as an example, the uplink transmission method of the embodiment of the present application includes: and the UE transmits auxiliary information to the network side equipment, wherein the auxiliary information indicates that when the antenna for transmitting the SRS by the UE is different from the antenna for transmitting the PUSCH or PUCCH, the auxiliary information corresponds to the minimum value of the interval between the OFDM symbols. The network side equipment configures SRS and PUSCH/PUCCH resources for the UE based on the auxiliary information of the UE, and when the minimum interval required by the auxiliary information reported by the UE is smaller, the interval between the SRS and the PUSCH/PUCCH resources configured by the network side equipment for the UE is preferably less than or equal to 0 or 1 predefined length, such as the length of a CP or 0 OFDM symbol; if the minimum interval required by the reported auxiliary information is large, the interval configured by the network is greater than 1 predefined length, for example, at least one OFDM symbol. In particular, the delay mentioned above represents the uplink and downlink scheduling restrictions for the UE, i.e. in the delay range, the UE does not need to accept any relevant PDCCH/PDSCH/PUCCH/PUSCH transmission requirements. In other words, if the network side device, through scheduling or configuration, makes the UE make a request for corresponding PDCCH/PDSCH/PUCCH/PUSCH transmission in the time including the symbol in the delay, the UE may choose not to respond.

In the uplink transmission method of the embodiment of the application, the terminal sends first information to the network side equipment, wherein the first information is used for indicating the interval time required by the antenna switching process; receiving uplink transmission scheduling information sent by network side equipment; and when the uplink transmission resource scheduled by the uplink transmission scheduling information meets the interval time requirement indicated by the first information, the mode of performing uplink transmission according to the uplink transmission scheduling information avoids the interval time required by antenna switching when the network side equipment performs resource scheduling for the terminal so as to avoid transmission performance loss of the terminal caused by substandard power in the antenna switching time interval.

Taking the first information as the capability information as an example, the uplink transmission method of the embodiment of the present application includes: the UE transmits capability information to the network, the capability information indicating that the UE transmits SRS with different antennas for delay capability than the PUSCH or PUCCH. The network side equipment configures SRS and PUSCH/PUCCH resources for the UE based on the UE capability, and when the delay reported by the UE is small, the interval between the SRS and the PUSCH/PUCCH resources configured by the network side equipment for the UE is preferably less than or equal to 0 or 1 predefined length, such as the length of a CP or 0 OFDM symbol; if the reported delay is large, the interval configured by the network side device is greater than 1 predefined length, for example, at least one OFDM symbol.

Taking the first information as the auxiliary information as an example, the uplink transmission method of the embodiment of the present application includes: and the UE transmits auxiliary information to the network side equipment, wherein the auxiliary information indicates that when the antenna for transmitting the SRS by the UE is different from the antenna for transmitting the PUSCH or PUCCH, the auxiliary information corresponds to the minimum value of the interval between the OFDM symbols. The network side equipment configures SRS and PUSCH/PUCCH resources for the UE based on the auxiliary information of the UE, and when the minimum interval required by the auxiliary information reported by the UE is smaller, the interval between the SRS and the PUSCH/PUCCH resources configured by the network side equipment for the UE is preferably less than or equal to 0 or 1 predefined length, such as the length of a CP or 0 OFDM symbol; if the minimum interval required by the reported auxiliary information is larger, the interval configured by the network is larger than 1 predefined length, for example, at least one OFDM symbol.

Similar to the terminal-side method embodiment, in some embodiments of the present application, the first information may include a target capability level, where the target capability level is one of a plurality of capability levels, and each capability level corresponds to a respective interval time. Optionally, the first information may be terminal capability information, and the terminal reports the interval time required for the antenna switching process to the network side device by using the terminal capability information carrying the target capability level.

The target capability level may also be referred to as a target scheduling level, and the target scheduling level is used to assist the network side device in performing uplink transmission scheduling. The target scheduling level is one of a plurality of scheduling levels, and each scheduling level corresponds to a respective interval time. Optionally, the first information may be terminal auxiliary information, and the terminal reports the interval time required by the antenna switching process to the network side device by using the terminal auxiliary information to carry the target scheduling level. It is worth to be noted that the capability level and the scheduling level may be interchanged in some scenarios, and in the embodiment of the present application, the capability level is merely used as an exemplary illustration, and the implementation manner of the scheduling level may also be an implementation manner of the capability level.

The unit of the interval time corresponding to the capability level may be milliseconds (ms), slots (slots), symbols (symbols), and the like. The interval time corresponding to the capability level may include: 0, 1 or more ms/slots/symbols.

Further, the interval time corresponding to each of the plurality of capability levels is correlated with the subcarrier interval SCS. For example, the number of symbols included in the interval time corresponding to one capability level may be different for different SCS.

Similar to the terminal side method embodiment, the system can support a plurality of capability levels, and the corresponding interval time of different capability levels is not completely the same. The embodiment of the present application takes 2 capability levels as an example for illustration, where the multiple capability levels include a first capability level and a second capability level, and an interval time corresponding to the first capability level is less than an interval time corresponding to the second capability level. Taking the unit of the interval time as the time domain symbol as an example, the interval time corresponding to the first capability level includes 0 or 1 time domain symbol, and the interval time corresponding to the second capability level includes 1 or more time domain symbols. For example, the UE feeds back first information to the base station, where the first information may be UE capability or UE assistance information, and the first information indicates a delay capability level when an antenna of the UE transmitting the SRS is different from an antenna of the PUSCH or PUCCH. The delay capability is divided into a capability level 1 and a capability level 2, and the delay required by the capability level 1 is smaller than that of the capability level 2. The time delay can be related to the SCS, and the time delay is not consistent under different SCSs. Taking the delay as an OFDM symbol level as an example, the delay may include one or more OFDM symbols and the delay does not exceed 5 OFDM symbols. Wherein the OFDM symbols include CP-OFDM and DFT-S-OFDM.

In a carrier aggregation CA or dual connectivity DC operating mode, a plurality of capability levels respectively correspond to interval time on a CA frequency band combination or a DC frequency band combination. The plurality of capability levels correspond to the interval time on one CA band combination or one DC band combination respectively. In addition, the plurality of capability levels corresponding to different CA frequency band combinations or different DC frequency band combinations may also be different.

Since SCS may be different on different carriers, the interval time required for the antenna switching process indicated by the first information needs to consider alignment issues of different carriers in addition to the processing time of antenna switching, and therefore, the interval time on the CA frequency band combination or the DC frequency band combination may include one or more time slots.

And under the condition that the uplink transmission corresponding to the antenna switching process comprises SRS transmission, the antenna port of a transmitting antenna of the SRS transmission is different from that of a transmitting antenna of PUSCH transmission or PUCCH transmission, and the required interval time between the SRS transmission and the PUSCH transmission or PUCCH transmission is positioned on 0 or 1 or more OFDM symbols before or after the SRS transmission. Under the condition that uplink transmission corresponding to the antenna switching process comprises two SRS transmission, antenna ports of transmitting antennas of the two SRS transmission are different, and the required interval between the two SRS transmission is 0 or 1 or more OFDM symbols.

In the uplink transmission method of the embodiment of the application, network side equipment receives first information sent by a terminal, wherein the first information is used for indicating the interval time required by an antenna switching process; and the network side equipment sends uplink transmission scheduling information to the terminal according to the first information, wherein the uplink transmission scheduling information is used for scheduling uplink transmission resources. Therefore, the first information is considered when the resource scheduling is carried out on the terminal, so that the interval time required by antenna switching is avoided, and the transmission performance loss caused by substandard power of the terminal in the antenna switching time interval can be avoided.
