Description

Communication method, device and apparatus

Technical Field

The present application relates to the field of communications technologies, and in particular, to a communication method, device and apparatus.

Background

Currently, fifth generation mobile communication technology (the 5)^thgeneration, 5G) New Radio (NR) system, it is specified that a base station can configure 4 bandwidth parts (BWPs) for a terminal device at most in uplink and downlink. After configuring BWP for the terminal device, if the terminal device needs to operate in a certain carrier bandwidth part, the base station needs to activate the carrier bandwidth part, for example, the base station may activate through Radio Resource Control (RRC) signaling or Media Access Control (MAC) signaling, and only one BWP can be activated at a time, and then the terminal device may activate at the activated BThe WP transmits and receives signals.

Only one BWP is activated at the same time, so the terminal device only processes services on one activated BWP, and the activated BWP is not necessarily capable of satisfying all service requirements, so in order to satisfy different service requirements, the terminal device may need to switch BWPs, and during the switching process, the terminal device cannot process any services. Then, since the terminal device cannot process the service in the handover process, the delay of service processing may be increased, and particularly, the requirement for the service with a high delay requirement may not be met.

Disclosure of Invention

The embodiment of the application provides a communication method, equipment and a device, which are used for reducing the time delay of a terminal device for processing a service.

The time required for switching the radio frequency device of the terminal equipment between the BWPs with the same frequency band and the same central frequency point is shorter, the time required for switching between BWPs in the same frequency band and different center frequency points is relatively long, while the time required for switching between BWPs in different frequency bands is much longer, for example, the switching time of the rf device of the terminal device on H BWPs is short, and the terminal device can preferentially receive signals on H BWPs, for the traffic carried on H BWPs, the time delay caused by the BWP handover procedure becomes short, moreover, the H BWPs are BWPs with the same frequency band and different center frequency points, the services carried on the H BWPs may be higher priority services or more important services, by adopting the signal receiving mode provided by the embodiment of the application, the time delay of the terminal equipment for processing the service with higher priority or the more important service is reduced. For the service with the lower service priority, the service can be carried through M BWPs, and for the service with the lowest service priority, the service can be carried through K BWPs, thereby meeting the requirements of different services.

Since the larger the subcarrier interval of the BWP is, the smaller the time unit is, and the smaller the delay of receiving the signal on the corresponding BWP is, in the embodiment of the present application, when receiving the signal on N BWPs, the terminal device may receive the signal on the BWP corresponding to the large subcarrier interval first and then receive the signal on the BWP corresponding to the small subcarrier interval, so that the terminal device may receive the signal earlier, and reduce the delay of processing the traffic by the terminal device.

Detailed Description

In order to better understand the technical solutions provided by the embodiments of the present application, the following detailed description is made with reference to the drawings and specific embodiments.

Hereinafter, some terms in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

1) Terminal equipment, including devices that provide voice and/or data connectivity to a user, may include, for example, handheld devices with wireless connection capability or processing devices connected to wireless modems. The terminal device may communicate with a core network via a Radio Access Network (RAN), exchanging voice and/or data with the RAN. The terminal device may include a User Equipment (UE), a wireless terminal device, a mobile terminal device, a subscriber unit (subscriber unit), a subscriber station (subscriber station), a mobile station (mobile), a remote station (remote station), an Access Point (AP), a remote terminal device (remote), an access terminal device (access terminal), a user terminal device (user terminal), a user agent (user agent), a user equipment (user device), or the like. For example, mobile phones (or so-called "cellular" phones), computers with mobile terminal equipment, portable, pocket, hand-held, computer-included or vehicle-mounted mobile devices, smart wearable devices, and the like may be included. For example, Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), and the like. Also included are constrained devices, such as devices that consume less power, or devices that have limited storage capabilities, or devices that have limited computing capabilities, etc. Examples of information sensing devices include bar codes, Radio Frequency Identification (RFID), sensors, Global Positioning Systems (GPS), laser scanners, and the like.

2) A network device, e.g., including a base station (e.g., access point), may refer to a device in an access network that communicates over the air, through one or more cells, with wireless terminal devices. The network device may be configured to interconvert received air frames and Internet Protocol (IP) packets as a router between the terminal device and the rest of the access network, which may include an IP network. The network device may also coordinate attribute management for the air interface. For example, the network device may include an evolved Node B (NodeB or eNB or e-NodeB) in a Long Term Evolution (LTE) system or an evolved LTE system (LTE-Advanced, LTE-a), or may also include a next generation Node B (gNB) in a 5G NR system, or may also include a Centralized Unit (CU) and a Distributed Unit (DU) in a cloud access network (cloudlan) system, which is not limited in the embodiments.

3) BWP, which is understood to be a resource block given a set of parameters, includes sub-carrier spacing (SCS) and Cyclic Prefix (CP), where CP is formed by copying signals at the tail of an Orthogonal Frequency Division Multiplexing (OFDM) symbol to the head, and CP mainly includes Normal Cyclic Prefix (NCP) and Extended Cyclic Prefix (ECP).

The following describes a scenario to which the embodiment of the present application is applied, and the embodiment of the present application may be applied to communication between terminal devices, for example, communication between a mobile phone and a mobile phone, communication between a mobile phone and an in-vehicle device, communication between an in-vehicle device and an in-vehicle device (V2X), and the like. Referring to fig. 1, fig. 1 includes a first terminal device, a second terminal device, and three terminal devices, for example, all 3 terminal devices are vehicle-mounted devices, and a network device may configure a BWP for each of the 3 terminal devices, so that the first terminal device, the second terminal device, and the third terminal device may communicate with each other, and a communication process between the three terminal devices is briefly described below.

For example, the network device configures 4 BWPs for the first terminal device to receive signals, where the 4 BWPs are BWP1, BWP2, BWP3 and BWP4, the third terminal device transmits the first signal to the first terminal device through BWP1, and the second terminal device transmits the second signal to the first terminal device through BWP2, and the first terminal device can only receive signals on one BWP at the same time, for example, after the first terminal device receives the first signal on BWP1, a Radio Frequency (RF) device of the first terminal device needs to switch to BWP2 to receive the second signal on BWP 2. During the switching of the RF device, the first terminal device cannot receive the signal, and obviously, the switching process causes the second signal to be received with a delay. If the second signal is a service with a higher delay requirement, serious consequences may be caused, for example, the second signal is "a first terminal device and a second terminal device are about to collide", obviously, when the second signal is delayed, when the first terminal device receives the second signal, two terminal devices may collide, which may cause a traffic accident, etc.

To distinguish the BWPs before and after the RF device is switched, the BWP before the RF device is defined as the source BWP, and the BWP after the RF device is defined as the target BWP. The RF device switches from the source BWP to the target BWP, wherein switching may be understood as the RF device adjusting the corresponding parameters to adapt the parameters of the target BWP such that the RF device may receive signals on the target BWP, and the time it takes for the RF device to switch from the source BWP to the source BWP is the RF switching time. Switching of the RF device may include switching in three cases, as described below.

In the first case, the source BWP and the target BWP belong to the same frequency band and have the same center frequency point.

In this case, the source BWP and the target BWP belong to the same frequency band, and the central frequency point is also the same, but the bandwidths of the source BWP and the target BWP may be different, so that the operating bandwidth of the RF device needs to be adjusted, then during the switching process, the terminal device only needs to adjust the operating bandwidth of the RF device and adjust the Fast Fourier Transform (FFT) size of the RF device, that is, the switching time includes the time for adjusting the operating bandwidth of the RF device and the time for adjusting the FFT size of the RF device. The FFT size of the RF device refers to the number of subcarriers that the RF device can process at one time.

In the second case, the source BWP and the target BWP belong to the same frequency band and have different center frequency points.

In the switching process, the terminal device needs to adjust the central frequency point of the RF device in addition to the operating bandwidth and the FFT size of the RF device, that is, the switching time includes a time for adjusting the operating bandwidth of the RF device, a time for adjusting the FFT size of the RF device, and a time for adjusting the central frequency point of the RF device. Obviously, the switching time will be longer relative to that of the first case.

In the third case, the source BWP and the target BWP belong to different frequency bands.

In the switching process, the terminal equipment needs to adjust the frequency band of the RF device in addition to adjusting the operating bandwidth of the RF device, adjusting the FFT size of the RF device, and adjusting the center frequency point of the RF device. That is, the switching time includes a time to adjust an operating bandwidth of the RF device, a time to adjust an FFT size of the RF device, a time to adjust a center frequency point of the RF device, and a time to adjust a frequency band of the RF device. Obviously, the switching time will be longer relative to the switching time of the second type of switching.

When the RF device is switched, since the terminal device cannot process the service in the switching process, and since the terminal device cannot process the service in the switching process, the delay of service processing may be increased, and particularly, the requirement for the service with a high delay requirement may not be satisfied.

In order to reduce the time delay of the terminal device for processing the service, embodiments of the present application provide a communication method, which is executed by the terminal device, for example. Referring to fig. 2, the process of the method is as follows.

S201, determining N bandwidth portions BWP configured for the terminal equipment, wherein N is a positive integer;

s202, receiving signals on the N BWPs according to a preset sequence, where the preset sequence is: firstly, receiving signals on H BWPs in the N BWPs, wherein the H BWPs belong to the same frequency band and have the same central frequency point, secondly, receiving signals on M BWPs in the N BWPs, wherein the M BWPs belong to the same frequency band and have different central frequency points, and finally, receiving signals on K BWPs in the N BWPs, wherein H, K and L are integers which are more than or equal to 0, and H, M and K are less than or equal to N.

As mentioned above, the network device may configure the BWP for the terminal device, and the terminal device may operate on the BWP configured by the network device, and hereinafter, the network device takes the base station as an example. After configuring the BWP for the terminal device, the terminal device may then transceive signals over the configured BWP.

The number of BWPs configured by the base station for the terminal device may be one or more, and the number of BWPs configured for the terminal device is not limited herein. For example, the base station configures a plurality of BWPs for the terminal device, where all BWPs may belong to different frequency bands, that is, the frequency bands to which different BWPs belong in all BWPs are different, or a part of BWPs may belong to different frequency bands and the remaining BWPs belong to the same frequency band, or all BWPs may belong to the same frequency band. In this context, a "frequency band" may also be understood as a "carrier", if two BWPs belong to the same carrier, the two BWPs may be considered to belong to the same frequency band, and if the two BWPs belong to different carriers, the two BWPs may be considered to belong to different frequency bands. In addition, for BWPs belonging to the same frequency band, the center frequency points of these BWPs may all be the same, or some BWPs may have the same center frequency point, while the remaining BWPs have different center frequency points, or all BWPs may have different center frequency points. The center frequency point refers to a center value of a frequency range occupied by one BWP, for example, if a frequency range occupied by one BWP is 1920MHz-1922MHz, the center frequency point of the BWP is 1921 MHz.

When configuring BWP for the terminal device, the base station may configure the BWP according to the capability of the terminal device, where the capability of the terminal device includes at least one of the bandwidth adjustment capability of the RF device of the terminal device, the frequency band range supported by the RF device of the terminal device, and the Fast Fourier Transform (FFT) capability of the RF device of the terminal device, and may further include other capabilities. Of course, besides configuring the BWP for the terminal device according to the processing capability of the terminal device, the base station may also configure the BWP for the terminal device according to other conditions, which is not limited in particular. In summary, after the base station configures BWP for the terminal device, for example, the base station configures N BWPs for the terminal device, the terminal device may determine the N BWPs, so that the terminal device may receive or transmit signals through the N BWPs, where N is a positive integer. Next, a flow of the terminal device receiving signals on N BWPs will be described.

In the case that other terminal devices directly communicate with the terminal device, the terminal device may not necessarily know in advance which BWPs other terminal devices would transmit signals on, and a manner for the terminal device to determine which BWPs other terminal devices receive signals on is that the base station configures a connection mechanism in advance between the other terminal devices and the terminal device, where the connection mechanism may be understood as that the base station specifies which BWPs are specifically passed between the other terminal devices and the terminal device, and the terminal device may determine which BWPs the other terminal devices may transmit signals through. However, the terminal device still cannot know which BWP the other terminal devices transmit signals through at any time, and therefore the terminal device needs to perform blind detection on the possible BWPs.

Since the terminal device can only activate one BWP at a time, i.e. the terminal device can only attempt to receive on one BWP at a time, the terminal device can only perform blind detection on these BWPs sequentially, i.e. after blind detection on one BWP, blind detection on another BWP is performed, which involves the order of blind detection on BWPs.

As an example, the terminal device may perform blind detection in a random order, which is simple.

Or, as another example, the terminal device may perform blind detection according to the preset sequence described in step 202, and in this way, the switching time may be reduced.

If the terminal device performs blind detection according to the preset sequence in step 202, the process of receiving signals by the terminal device may be divided into 3 sub-processes, where the 3 sub-processes are respectively: a process of receiving signals on H BWPs, a process of receiving signals on M BWPs, and a process of receiving signals on K BWPs. The 3 sub-processes are described separately below.

1. The 1 st sub-process, the terminal device receives signals on H BWPs.

If H is 1, the terminal device may receive a signal directly on the BWP.

If H is an integer greater than or equal to 2, then the terminal device receives the signal on H BWPs, and also on each of the H BWPs in turn, which involves the terminal device switching between H BWPs.

For example, the terminal device may receive signals on the H BWPs in a random order, or, to reduce the time it takes for the terminal device to receive signals on the BWPs, the terminal device may receive signals on the H BWPs in a first order. The first order is, for example, an order of decreasing subcarrier intervals of BWPs, for example, the terminal device first receives a signal on a first BWP of the H BWPs, and then receives the signal on a second BWP of the H BWPs after the first BWP is received, where the subcarrier interval of the first BWP is greater than the subcarrier interval of the second BWP. That is, the first order may be that the terminal device receives the signal on the BWP with the larger subcarrier spacing first and then receives the signal on the BWP with the smaller subcarrier spacing.

Because the larger the subcarrier interval is, the smaller the corresponding time unit is, for example, the length of a slot (slot) corresponding to the subcarrier interval of 30kHz is smaller than the length of a slot corresponding to the subcarrier interval of 15kHz, therefore, the larger the subcarrier interval of BWP is, the smaller the time delay of the transmission signal is, and therefore, the terminal device receives in the first order, which is helpful for reducing the time delay of the terminal device for processing the traffic. Moreover, generally, the service carried by the BWP with the larger subcarrier spacing is often a service with a higher priority or a service with a higher requirement on the delay, and the terminal device receives the service according to the first order, which can also ensure that the service with the higher priority or the service with the higher requirement on the delay can be processed preferentially.

Among the H BWPs, there may be BWPs with the same subcarrier spacing, for which, for example, the terminal device may receive in a random order. For example, if the H BWPs include BWP1 and BWP2, and BWP1 and BWP2 have the same subcarrier spacing, the terminal device may receive the signal on BWP1 first or may receive the signal on BWP2 first, which is not limited herein.

After the terminal device finishes receiving on H BWPs belonging to the same frequency band and having the same center frequency point, it may receive signals on M BWPs, which is described below.

2. Sub-process 2, the terminal device receives signals on M BWPs.

If M is 1, the terminal device may receive a signal directly on the BWP.

If M is an integer greater than or equal to 2, the terminal device receives the signal on M BWPs, and also on each of the M BWPs in turn, which involves the terminal device switching between the M BWPs.

For example, the terminal device may receive signals on the H BWPs in a random order, or, to reduce the time it takes for the terminal device to receive signals on the BWPs, the terminal device may receive signals on the H BWPs in a first order. For the random sequence or the first sequence, reference may be made to the above discussion, and the description thereof is omitted.

As described above, when receiving on M BWPs, the terminal device receives in the first order, which can also ensure that the service with higher priority or higher requirement on delay can be processed preferentially.

Among the M BWPs, there may be BWPs with the same subcarrier spacing, for which, for example, the terminal device may receive in a random order. The random sequence can refer to the above description, and is not described herein.

After the terminal device finishes receiving on M BWPs belonging to the same frequency band and having the same center frequency point, it may receive signals on K BWPs, which is described below.

3. In the 3 rd sub-process, the terminal device receives signals on K BWPs.

If K is 1, the terminal device may receive a signal directly on the BWP.

If K is an integer greater than or equal to 2, the terminal device receives the signal on K BWPs, and also on each of the K BWPs in turn, which involves the terminal device switching between the K BWPs.

For example, the terminal device may receive signals on the K BWPs in a random order, or, to reduce the time it takes for the terminal device to receive signals on the BWPs, the terminal device may receive signals on the K BWPs in a first order. For the random sequence or the first sequence, reference may be made to the above discussion, and the description thereof is omitted.

Similarly, when receiving on K BWPs, the terminal device receives according to the first order, and can also ensure that the service with higher priority or higher requirement on delay can be processed preferentially.

Among the K BWPs, there may be BWPs with the same subcarrier spacing, for which, for example, the terminal device may receive in a random order. The random sequence can refer to the above description, and is not described herein.

It should be noted that, although the receiving process in the preset order described in the embodiment of the present application includes 3 sub-processes, in practical applications, the 3 sub-processes do not necessarily all occur, and only one of the 3 sub-processes may occur, for example, the base station only configures BWPs that belong to the same frequency band and have different center frequency points for the terminal device, and only the 2 nd sub-process therein may occur, or only two of the 3 sub-processes may occur, for example, the base station does not configure BWPs that belong to the same frequency band and have the same center frequency point for the terminal device, and then the 1 st sub-process, and only the 2 nd sub-process and the 3 rd sub-process therein may not occur, that is, the preset order describes only the receiving order, and the terminal device may process in the preset order no matter how many sub-processes occur therein, for example, only the 1 st sub-process and the 3 rd sub-process therein occur, the terminal device performs the 1 st sub-process and then performs the 3 rd sub-process according to the preset sequence, and the embodiment of the application does not limit which sub-processes specifically occur, so long as the terminal device receives the sub-processes according to the preset sequence.

For example, the base station configures 6 BWPs for the terminal device, please refer to fig. 3, where the 6 BWPs correspond to a, b, c, d, e, and g in fig. 3, where an abscissa f in fig. 3 represents frequency and CB represents carrier. Among the 6 BWPs, a and b belong to the same carrier and have the same center frequency point, and the subcarrier spacing of a is greater than the subcarrier spacing of b, c and d belong to the same carrier, and the subcarrier spacing of c is greater than the subcarrier spacing of d but have different center frequency points, and e and g belong to two BWPs of different carriers and have a subcarrier spacing of g greater than the subcarrier spacing of e, that is, a and b belong to the H BWPs discussed above, c and d belong to the M BWPs discussed above, and e and g belong to the K BWPs discussed above. When other terminal devices simultaneously transmit signals to the terminal devices on a, b, c, d, e and g, the terminal devices receive the signals according to a preset sequence, namely, the signals are received on a-b firstly (a-b indicates that the terminal devices may receive on a or b firstly), after the signals are received on a-b, the terminal devices receive the signals on c-d (c-d indicates that the terminal devices may receive on c or d firstly), and after the signals are received on c-d, the signals are received on e-g (e-g indicates that the terminal devices may receive on e or g firstly). Wherein, the terminal device has 2 BWPs in each sub-process, and if the terminal device receives in the first order, that is, receives sequentially according to the size order of the subcarrier intervals corresponding to the BWPs, the receiving order is: a. b, c, d, g and e. In fig. 3, 3 subprocesses are included as an example, but the number of subprocesses is not limited in practice.

If other terminal devices send signals to the terminal device on multiple BWPs simultaneously, but the terminal device receives the signals in a preset order, that is, the signals on some BWPs may be received later, which may result in that the terminal device fails to receive on some BWPs, and if the terminal device fails, the terminal device may Request other terminal devices to resend the signals through a hybrid automatic Repeat Request (HARQ), and after the resending, the terminal device receives the signals again. In fact, when the terminal device fails to receive, the problem may be solved by other methods, which are not listed here.

In this embodiment, when receiving a signal, a terminal device first receives a signal on H BWPs of N BWPs that belong to the same frequency band and have the same center frequency point, then receives a signal on M BWPs of N BWPs that belong to the same frequency band and have different center frequency points, and finally receives a signal on K BWPs of N BWPs that belong to different frequency bands, which can reduce the switching time of the RF device of the terminal device to the greatest extent, thereby reducing the delay of the terminal device in processing a service.

In the embodiment of the application, the terminal equipment receives the signals according to the preset sequence, which is beneficial to reducing the time delay of the terminal equipment for processing the service with higher priority or the more important service.

In order to reduce the time delay of the terminal device for processing the service, the embodiment shown in fig. 2 introduces a communication method, and a communication method is provided below, which can also reduce the time delay of the terminal device for processing the service. Referring to fig. 4, the flow of the method is as follows.

S401, receiving a signal on a first BWP in N BWPs configured for a terminal device, wherein the N BWPs belong to a BWP sequence, and the BWP sequence is arranged according to the sequence of subcarrier intervals of the N BWPs from big to small;

s402, after receiving on the first BWP, receiving a signal on a second BWP of the BWP sequence, where the subcarrier spacing of the first BWP is greater than the subcarrier spacing of the second BWP.

The network device may configure the BWP for the terminal device, and the terminal device may operate on the BWP configured by the network device, and hereinafter, the network device continues to take the base station as an example. After configuring the BWP for the terminal device, the terminal device may then transceive signals over the configured BWP. For example, the network device configures N BWPs for the terminal device, and for the content of configuring the BWPs for the terminal device by the network device, reference may be made to the related description in the embodiment shown in fig. 3, which is not repeated herein.

As an embodiment, the network device configures the BWP sequence for the terminal device, that is, the network device configures N BWPs for the terminal device, and configures the N BWPs to belong to the BWP sequence simultaneously. The BWP sequence includes the N BWPs, and the N BWPs are arranged in the BWP sequence according to the order of the subcarrier spacing from large to small.

Or, the network device only configures N BWPs for the terminal device, and the terminal device may sequence the N BWPs in order of the subcarrier intervals of the N BWPs from large to small by itself to obtain a BWP sequence.

If the BWP sequence is configured directly by the base station, no re-ordering by the terminal device is required, and less work is required for the terminal device, whereas if the BWP sequence is obtained by the terminal device itself, no additional configuration by the network device is required, which helps to reduce the amount of data for the messages sent by the network device to configure BWP. The specific manner used by the terminal device to determine the BWP sequence may be specified by a protocol, or may also be a default manner of the system, and the like, which is not limited in particular.

In summary, after obtaining the BWP sequence, the terminal device may receive the signals in the order of the BWPs in the BWP sequence when receiving the signals, for example, the BWP sequence includes a first BWP and a second BWP, where the first BWP is arranged before the second BWP, that is, the subcarrier spacing of the first BWP is greater than the subcarrier spacing of the second BWP, and then the terminal device may receive the signals on the first BWP first, and then receive the signals on the second BWP after the reception on the first BWP.

For example, referring to fig. 5, 6 BWPs are configured for the terminal device, that is, corresponding to a, b, c, d, e, and g in fig. 5, where an abscissa f in fig. 5 represents frequency, CB represents carrier, and the 6 BWPs are arranged in order of subcarrier spacing from large to small, where the arrangement order of the 6 BWPs is: g > a > b > c > d > e, and the obtained BWP sequence is as follows: g. a, b, c, d, e. When receiving a signal transmitted from another terminal, the terminal receives the signal in g according to the BWP sequence, receives the signal in a after the reception in g, receives the signal in b after the reception in a, receives the signal in d after the reception in c, and receives the signal in e after the reception in d.

As described above, the time required for the terminal device to receive the signal on the BWP corresponding to the large subcarrier interval is shorter, so that the time delay of the high-priority traffic can be reduced by receiving the signal on the BWP corresponding to the large subcarrier interval and then receiving the signal on the BWP corresponding to the small subcarrier interval.

Among the N BWPs, there may be L BWPs with the same subcarrier spacing, and for such BWPs, the BWPs may be arranged in a random order in the BWP sequence, or may be arranged in the BWP sequence according to the order of the corresponding switching durations from large to small, where L is an integer less than or equal to N and greater than or equal to 0. For example, if there are 3 BWPs with the same subcarrier interval among the N BWPs, which are BWPs 1-BWP 3, the 3 BWPs may be randomly arranged in the BWP sequence, or if the switching duration of BWP1 > the switching duration of BWP3 > the switching duration of BWP2, the order of the 3 BWPs in the BWP sequence may be: BWP1, BWP3, BWP 2. The switching duration corresponding to one BWP is a duration required for the radio frequency device of the terminal device to switch from another BWP to the BWP. This is how the terminal device knows the handover duration for each of the L BWPs. For example, one method for learning the switching duration of BWP is: and judging whether the other BWP is the same as each BWP in the L BWPs or not, and judging whether the other BWP and each BWP in the L BWPs belong to the same frequency band or not. That is, the switching time is determined according to the relationship between the frequency band and the center frequency point of another BWP and the frequency band and the center frequency point of each BWP in the L BWPs.

Specifically, another BWP may be considered a source BWP and one BWP may be considered a target BWP. If the source BWP and the target BWP belong to the same frequency band and the center frequency points are the same, the switching duration is t1, if the source BWP and the target BWP belong to the same frequency band and the center frequency points are different, the switching duration is t2, and if the source BWP and the target BWP belong to different frequency bands and the switching duration is t3, the switching duration is t1< t2< t 3. That is, if the BWP of the L BWPs is in the same frequency band as the source BWP and the center frequency band is the same, the signal is received on the BWP, then the BWP of the L BWPs in the same frequency band as the source BWP and the center frequency band is determined, the signal is received on the BWP, and finally the signal is received on the BWP in the different frequency band from the source BWP.

For example, if the subcarrier intervals corresponding to the third BWP and the fourth BWP are the same, the second BWP and the third BWP belong to the same frequency band, and the second BWP and the fourth BWP belong to different frequency bands, the obtained BWP sequence is: the second BWP, the third BWP and the fourth BWP, after the terminal device finishes receiving on the second BWP, the terminal device needs to receive signals on the remaining third BWP and fourth BWP, and then the terminal device receives the signal on the third BWP first, and then receives the signal on the fourth BWP after finishing receiving on the third BWP.

The aforementioned "first", "second", etc. in the "first BWP," second BWP, "third BWP," fourth BWP, "fifth BWP and" sixth BWP "are only for distinguishing the corresponding BWPs, and do not actually limit the frequency band, bandwidth, etc. of the BWPs.

Then, the embodiment of the present application further provides a communication method, which can implement the transmission of the signal.
