Background technique

Due to the large bandwidth of the New Radio (NR) system, the terminal equipment consumes too much power under the entire bandwidth, so the bandwidth part (BWP) defines that the operating bandwidth of the terminal equipment can be smaller than the system bandwidth.

Currently, the access network device generally sends signaling to the terminal device, and the terminal device switches back and forth between different BWPs based on the signaling. In this method, the air interface overhead is relatively large, and since the terminal device needs to process signaling frequently, the energy consumption of the terminal device is also relatively large.

Detailed ways

FIG. 1 is a schematic structural diagram of a wireless communication system according to an embodiment of the present application. The wireless communication system includes an access network device and one or more terminal devices.

In the wireless communication system, the access network equipment can provide communication coverage for a specific geographical area through integrated or external antenna equipment. One or more terminal devices located within the communication coverage of the access network device can all access the access network device. An access network device can manage one or more cells. Each cell has an identification, which is also called a cell identity (cell ID).

The terminal equipment and the access network equipment know the predefined configuration of the wireless communication system, including the radio access technology (RAT) supported by the system and the wireless resource configuration specified by the system (such as the radio frequency band and the basic configuration of the carrier) Wait. A carrier is a frequency range that conforms to system regulations. This frequency range can be determined by the center frequency of the carrier (referred to as the carrier frequency) and the bandwidth of the carrier. The pre-defined configurations of these systems can be part of standard protocols of the wireless communication system, or determined through interaction between terminal equipment and access network equipment. The content of the relevant standard protocol may be pre-stored in the memory of the terminal device and the access network device, or embodied as a hardware circuit or software code of the terminal device and the access network device.

In the wireless communication system, the terminal equipment and the access network equipment support one or more of the same RATs, such as NR, long term evolution (long term evolution, LTE), or RATs of future evolution systems. Specifically, the terminal device and the access network device use the same air interface parameters, coding scheme, modulation scheme, etc., and communicate with each other based on radio resources specified by the system.

The terminal device in the embodiment of the present application is a device with wireless transceiver function, which can be deployed on land, including indoor or outdoor, handheld or vehicle-mounted; can also be deployed on water (such as ships, etc.); can also be deployed on In the air (eg on airplanes, balloons and satellites, etc.). The terminal device may be a mobile phone (mobile phone), a tablet computer (pad), a computer with wireless transceiver function, a virtual reality (virtual reality, VR) terminal, an augmented reality (augmented reality, AR) terminal, an industrial control (industrial control) wireless terminals in ), wireless terminals in self-driving, wireless terminals in remote medical, wireless terminals in smart grid, wireless terminals in transportation safety , wireless terminals in smart cities, wireless terminals in smart homes, user equipment (UE), sensors with communication functions, etc.

Access network equipment is a device that provides wireless communication functions for terminal equipment. Access network equipment includes but is not limited to: next-generation base stations (g nodeB, gNB) in the fifth generation (5th generation, 5G), evolutionary Node B (evolved node B, eNB), radio network controller (radio network controller, RNC), node B (node B, NB), base station controller (base station controller, BSC), base transceiver station (base transceiver station, BTS), home base station (for example, home evolved nodeB, or home node B, HNB), baseband unit (baseBand unit, BBU), transmission point (transmitting and receiving point, TRP), transmitting point (transmitting point, TP), mobile exchange center, etc.

The terms or nouns used in the embodiments of the present application will be explained below first.

1. BWP

Due to the large bandwidth of the NR system, the terminal equipment consumes too much power under the entire bandwidth. Therefore, BWP defines that the operating bandwidth of the terminal equipment can be smaller than the system bandwidth. For example, a terminal device can be configured with multiple BWPs, and the terminal device can reduce power consumption by switching between different BWPs.

Exemplarily, for uplink communication or downlink communication, four BWPs are configured on a certain carrier of the terminal device, but only one BWP is activated at the same time, that is, the terminal device actually works on one BWP. The terminal device is configured with four BWPs for uplink communication and downlink communication at most, and only one uplink BWP and one downlink BWP are activated at the same time. Under Time Division Duplexing (TDD), the uplink BW and the downlink BWP are configured in pairs and have the same BWP index and center frequency, but the bandwidth and subcarrier spacing can be different.

When there is a need for bandwidth switching, BWP switching is required. Exemplarily, there are three ways of BWP switching, which are:

Mode 1, based on radio resource control (radio resource control, RRC) signaling

This method is used to switch the terminal device from the currently working BWP to the new BWP after RRC reconfiguration or activation of a secondary cell (Secondary Cell, SCell). The handover delay is typically 10-24 milliseconds (ms).

Method 2, based on downlink control information (DCI)

For example, the uplink is triggered by DCI format 0_1, and the downlink is triggered by DCI format 1_1. The switching delay is generally 1-2.5ms.

Method 3, based on timer

If the terminal device does not send and receive data for a long time, the timer expires, thereby triggering the terminal device to switch from the currently working BWP to a smaller BWP to save energy consumption. For example, the duration of the timer can be configured by bwp-InactivityTimer. The switching delay is generally 1-2.5ms.

2. Carrier Aggregation (CA)

CA is to aggregate two or more component carriers (Component Carrier, CC) together to support a larger transmission bandwidth. One cell (Cell) corresponds to one CC.

When using CA, multiple BWPs can be configured for a terminal device on one CC, and the identification information of BWPs on different CCs can be the same or different. Therefore, when there are multiple CCs, the index information of the cell and the identification information of the BWP can be used to jointly indicate a BWP.

It should be noted that only one BWP can be activated on one CC at the same time, but BWPs on multiple CCs can be activated simultaneously. For example, activate BWP1 on CC-1 and BWP2 on CC-2 at the same time.

At present, the switching methods of BWP used by terminal equipment are roughly divided into two categories, namely signaling trigger (such as the above-mentioned method 1 or 2) or timer trigger (such as the above-mentioned method 3). Each handover requires access network equipment. Sending signaling to a terminal device or starting a timer results in a large air interface resource overhead and a large energy consumption of the terminal device.

However, some services of the terminal equipment are periodic, and a certain type of BWP can be used. If the above method 1 or method 2 is adopted, it is necessary to frequently send signaling to the terminal equipment to trigger the terminal equipment to perform the operation between different BWPs. Switching back and forth between them results in larger air interface signaling.

Exemplarily, the terminal device performs data communication in a bandwidth of 20MHz, and transmits a positioning signal in a bandwidth of 100MHz, where 20MHz is BWP1 and 100MHz is BWP2. In order to make the terminal device save energy as much as possible, the terminal device periodically sends a positioning signal on the BWP2, and the terminal device expects to stay in the BWP2 for as short a time as possible. The terminal device needs to switch from BWP1 to BWP2, and after sending the positioning signal, switch back from BWP2 to BWP1. If the above-mentioned method 1 or 2 is adopted, it is necessary to frequently send RRC signaling or DCI to switch between BWP1 and BWP2, which not only occupies air interface resources, but also causes the terminal equipment to frequently process signaling. consumption increases.

To this end, an embodiment of the present application provides a method for activating a BWP, and the method can be executed by a terminal device or a component used for the terminal device (for example, a processor, a chip, or a chip system, etc.).

The following takes the terminal device executing the method as an example for description. Referring to FIG. 2 , the BWP activation method provided by the embodiment of the present application includes the following steps:

Step 201: The terminal device receives configuration information from the access network device, where the configuration information includes the activation period and the activation duration of the BWP.

Optionally, the configuration information may be carried in an RRC message (for example, it may be an RRC reconfiguration (reconfiguration) message, or an RRC release (release) message, etc.).

Step 202, the terminal device periodically activates the BWP according to the activation period and the activation duration of the BWP.

Wherein, the activation period is used to indicate the time interval between two adjacent BWP activations, that is, the use of the BWP has a period. For example, the terminal device uses the BWP to periodically send a positioning signal (such as a sounding reference signal (SRS)) to the access network device, and after each time the positioning signal is sent, it needs to switch to the BWP originally used, and also That is, the BWP that was in the active state before the BWP was activated is reactivated.

The activation duration is used to indicate the duration of the active state after the BWP is activated.

Optionally, after the BWP is activated, after the activation duration reaches, the BWP that was in the activated state before the BWP was activated is reactivated. That is, it switches to the BWP that was in the active state before the BWP was activated.

Exemplarily, five BWPs are configured for the terminal device, wherein BWP1 to BWP4 are common BWPs, and each handover is triggered to switch to or from the BWP based on RRC signaling, or based on DCI, or based on a timer. Switch to another BWP. The BWP5 is a BWP with an autonomous handover function defined in the embodiment of the application, the activation period of the BWP is T1, and the activation duration is L1. That is, the BWP5 is switched from the currently working BWP (such as any one of BWP1 to BWP4) to the BWP5 by the terminal device every T1 duration, that is, the currently working BWP is deactivated, and then BWP5 is activated, and BWP5 is activated every time. After activation, it remains activated for the duration of L1. BWP5 remains active during the L1 duration. It can be understood that during the L1 duration, the working bandwidth of the terminal device is BWP5.

Referring to FIG. 3 , it is an example diagram of BWP autonomous handover. BWP5 is a BWP with autonomous handover function. After each time period T1 arrives, the terminal device switches its working bandwidth from the current BWP (such as BWP1 or BWP2) to BWP5, and does not need to perform handover based on the signaling sent by the access network device. , which can reduce air interface resource overhead and energy consumption of terminal equipment. Moreover, after the terminal device works on the BWP5 for the L1 period, it automatically switches to the BWP (such as BWP1 or BWP2) that was in the active state before the BWP5 was activated, so there is no need to perform the switch based on the signaling sent by the access network device. The air interface resource overhead and the energy consumption of the terminal device can be further reduced.

It should be noted that the handover between common BWPs (BWP1 or BWP2 as shown in FIG. 3 ) may be performed based on signaling or triggering of a timer. For example, referring to FIG. 3 , if the terminal device does not send or receive data on BWP1 for a certain period of time, the timer times out, triggering the terminal device to switch from BWP1 to BWP2 based on a preconfigured or predefined policy.

As an implementation method, in this embodiment of the present application, the above-mentioned BWP with an autonomous handover function (BWP5 in FIG. 3 ) may be a BWP in an RRC inactive (inactive) state, and the configuration information of the above step 201 may be released by the RRC message. carry. In the above step 202, the terminal device periodically activates the BWP in the RRC inactive state according to the activation period and the activation duration of the BWP in the configuration information, so as to realize the autonomous handover of the BWP, so that the terminal device can be in the RRC inactive state. It realizes the transmission of uplink data or uplink signals and ensures the transmission of necessary information.

As another implementation method, in this embodiment of the present application, the above-mentioned BWP with an autonomous handover function (BWP5 in FIG. 3 ) may also be a BWP in an RRC idle (idle) state, and the configuration information of the above step 201 may be released by RRC message carrying. In the above step 202, the terminal device periodically activates the BWP in the RRC idle state according to the activation period and the activation duration of the BWP in the configuration information, so as to realize the autonomous handover of the BWP, so that the terminal device can realize the BWP in the RRC idle state. The transmission of uplink data or uplink signals ensures the transmission of necessary information.

In the above solution, the first activation time of the above BWP may further be configured.

Exemplarily, several different configuration manners are given below to notify the terminal device of the first activation time of the BWP.

Implementation method 1: Before the above step 202, the access network device also sends a first message to the terminal device, the first message indicates to enable the periodic activation of the BWP, and the first activation time of the BWP is related to the first message.

That is, the access network device indicates the first activation time of the above-mentioned BWP to the terminal device through the first message other than the above-mentioned configuration information. Therefore, the terminal device starts the periodic activation of the BWP according to the first message. Alternatively, it can be understood that the first message instructs the terminal device to enable the function of periodically activating the BWP, or it can be understood that the first message instructs the terminal device to activate the above-mentioned BWP for the first time.

As an implementation method, the first message itself (eg, through the name of the first message) may be used to indicate that the periodic activation of the BWP is turned on. As another implementation method, the first message may also carry an indication information (this embodiment of the present application also refers to the indication information as the second indication information), and the indication information may be used to indicate the periodicity of enabling the BWP activation.

As an implementation method, after receiving the first message, the terminal device immediately activates the BWP for the first time according to the first message or the above-mentioned second indication information carried in the first message. For example, after parsing the first message and acquiring the name of the first message, the terminal device starts to activate the BWP for the first time. For another example, after parsing the first message and acquiring the second indication information, the terminal device starts to activate the BWP for the first time. For another example, the terminal device starts to activate the BWP at the first time domain resource after the time domain resource where the first message is received. It can also be understood that the difference between the time domain resource at which the first message is received and the time position at which the BWP is activated for the first time is at least greater than or equal to the BWP handover preparation time. The BWP handover preparation time may be preset or preconfigured.

As another implementation method, the above-mentioned first message carries first time information, where the first time information is used to indicate the duration from the first activation of the BWP to the first time, where the first time is the time when the first message is received, or Preset or configured reference time point. That is, after receiving the first message, the terminal device activates the BWP for the first time at a specific moment (the duration from the moment to the first time is specified by the first time information). Or, the first time information is used to indicate the time point when the BWP is activated for the first time, that is, the first time information indicates an absolute time point, then after the terminal device receives the first message, at a specific moment (this moment is determined by the first time information specified) to activate the BWP for the first time.

Optionally, in the CA scenario, the above-mentioned first message may further carry the identification information of the BWP and the index information of the cell, and the index information of the cell indicates the cell corresponding to the BWP. That is, a BWP is jointly indicated by the index information of the cell and the identification information of the BWP. Or it can be understood that the BWP indicated by the identification information of the BWP is the BWP on the component carrier (CC) corresponding to the cell indicated by the index information of the cell. Among them, one cell corresponds to one component carrier.

The first implementation method is to instruct to start the periodic activation of the BWP through the first message. Correspondingly, the access network device may instruct to disable the periodic activation of the BWP by sending the second message to the terminal device. That is, when the terminal device receives the second message from the access network device, the function of periodically activating the BWP is disabled. For example, if the terminal device is currently working on the BWP with the autonomous switching function, after receiving the second message, the terminal device can immediately switch to the BWP that was in the active state before activating the BWP (BWP1 or BWP2 as shown in Figure 3) , or switch to the BWP that was in the active state before activating the BWP after the activation duration of the BWP is reached, and after the activation period of the BWP is reached, the BWP with the autonomous switching function will not be activated until it is reactivated. A message indicating that periodic activation of the BWP is turned on is received. For another example, if the terminal device is not currently working on the BWP with the autonomous switching function, after receiving the second message, the terminal device keeps working on the current BWP (BWP1 or BWP2 as shown in FIG. After the activation period of the BWP with the autonomous handover function arrives, the BWP is not activated again until a message for instructing to start the periodic activation of the BWP is received again.

As an implementation method, the second message itself (eg, by the name of the second message) may be used to indicate that the periodic activation of the BWP is turned off. As another implementation method, the second message can also carry an indication information (this embodiment of the present application also refers to the indication information as the third indication information), and the indication information can be used to indicate the periodicity of closing the BWP activation.

Optionally, the first message may be a medium access control control element (medium access control control element, MAC CE).

The specific implementation of the MAC CE is given below by taking the first message as the MAC CE as an example.

The implementation form of MAC CE is:

Example 1, the MAC CE includes 1-bit indication information, and the indication information is used to indicate that the periodic activation of BWP is turned on or the periodic activation of BWP is turned off.

For example, the indication information is "0", which is used to indicate that the periodic activation of the BWP is turned on; the indication information is "1", which is used to indicate that the periodic activation of the BWP is turned off. For another example, the indication information is "1", which is used to indicate that the periodic activation of the BWP is turned on; the indication information is "0", which is used to indicate that the periodic activation of the BWP is turned off.

This example 1 is suitable for the application scenario where only one BWP with autonomous handover function is configured for the terminal device, and the BWP with autonomous handover function is pre-configured or predefined, so the MAC CE may not carry the BWP. identification information.

Example 2, MAC CE contains 8 bits of information, specifically:

-Indication information, occupying 1 bit, used to indicate that the periodic activation of BWP is turned on or the periodic activation of BWP is turned off;

-BWP identification information (such as BWP ID), occupying 2 bits, used to indicate BWP; wherein, 2 bits can be used to indicate one of 4 different BWPs with autonomous handover function;

- Index information of the cell (such as SCell Index), which occupies 5 bits and is used to indicate the cell. Wherein, the index information of the cell and the identification information of the BWP jointly indicate the BWP on the CC corresponding to one cell. When the index information of the cell is not configured (for example, the 5 bits are empty), it indicates that there is only one CC or a default CC.

For example, referring to FIG. 4 , it is an example diagram of the format of the MAC CE corresponding to Example 2. The MAC CE includes indication information, BWP identification information and cell index information.

Based on the method of this example 2, one MAC CE may instruct to turn on/off the periodic activation of a BWP. If it is necessary to instruct to turn on/off the periodic activation of multiple BWPs, it may be to send multiple MAC CEs to the terminal device, respectively instructing to turn on/off the periodic activation of different BWPs.

It should be noted that only one BWP is active on the same CC, but multiple BWPs can be active on different CCs.

Example 3, the MAC CE contains 8*N bits of information, where N is an integer greater than 1, which is used to indicate turning on/off the periodic activation of multiple BWPs. Wherein, every 8 bits is used to indicate to turn on/off the periodic activation of a BWP, and the format of the information contained in each 8 bits may refer to the description of the above example 2.

For example, referring to FIG. 5, it is an example diagram of the format of the MAC CE corresponding to Example 3. The MAC CE contains 24 bits, and each 8 bits contains one indication information, one BWP identification information and one cell index information. The first 8 bits indicate the periodic activation of BWP A on/off, the second 8 bits indicate the periodic activation of BWP B on/off, and the third 8 bits indicate the periodic activation of BWP C on/off.

It should be noted that, if multiple BWPs indicated by the MAC CE belong to the same CC, the activation times of the multiple BWPs cannot overlap, that is, on a CC, only one BWP can be active at the same time. The activation periods of the multiple BWPs may be the same or different. The activation durations of the multiple BWPs may be the same or different.

If the multiple BWPs indicated by the MAC CE belong to different CCs, the activation times of the multiple BWPs may overlap, that is, on different CCs, two or more BWPs may be in the active state at the same time. The activation periods of the multiple BWPs may be the same or different. The activation durations of the multiple BWPs may be the same or different.

Example 4, two MAC CEs, one of which is used to instruct the periodic activation of the BWP to be turned on, and the other MAC CE is used to instruct the periodic activation of the BWP to be turned off.

This example 4 is a variant implementation of the above-mentioned example 1. In this example 4, it is not necessary to indicate the periodic activation of on/off BWP through indication information, but the periodic activation of on/off BWP is indicated by the name of the MAC CE. The name of the MAC CE may be indicated by a MAC subheader (subheader) in a MAC sub (sub) protocol data packet (Protocol data unit, PDU).

Example 5, two MAC CEs, both containing 8-bit information, one of the MAC CEs is used to indicate that the periodic activation of the BWP is turned on, and the other MAC CE is used to indicate that the periodic activation of the BWP is turned off. The formats of the two MAC CEs are:

- Index information of the cell (such as SCell Index), which occupies 5 bits and is used to indicate the cell. Wherein, the index information of the cell and the identification information of the BWP jointly indicate the BWP on the CC corresponding to one cell. When the index information of the cell is not configured (for example, the 5 bits are empty), it means that there is only one CC or the default CC;

- Reserve 1 bit.

This example 5 is a variant implementation of the above-mentioned example 2. In this example 5, it is not necessary to indicate the periodic activation of BWP on/off through indication information, but the periodic activation of on/off BWP is indicated through the name of the MAC CE.

Example 6, two MAC CEs both contain 8*N bits of information, where one MAC CE is used to instruct the periodic activation of multiple BWPs to be turned on, and the other MAC CE is used to instruct the periodic activation of multiple BWPs to be turned off. Both of the two MAC CEs contain 8*N bits of information, where N is an integer greater than 1. Wherein, every 8 bits is used to indicate to turn on/off the periodic activation of a BWP, and the format of the information contained in each 8 bits may refer to the description of the above example 2.

This example 6 is a variant implementation of the above example 3. In this example 6, it is not necessary to indicate the periodic activation of BWP on/off through indication information, but the periodic activation of on/off BWP is indicated through the name of the MAC CE.

After the terminal device receives any of the MAC CEs in the above examples 1 to 6, it can immediately turn on or off the periodic activation of the corresponding BWP, or it can be based on pre-configured or predefined time information (for example, it can be an absolute time or distance. Receive a relative duration of the MAC CE) to turn on or off the periodic activation of the corresponding BWP, or it can also be based on the time information received from the MAC CE (for example, it can be an absolute time or a distance from receiving the MAC CE. Relative duration) to turn on or off the periodic activation of the corresponding BWP, or it can also be turned on or off based on the time information received from the above step 201 (for example, it can be an absolute time or a relative duration from receiving the MAC CE) Periodic activation of the corresponding BWP.

In the above examples 1 to 6, one MAC CE is used to instruct the periodic activation of BWP to be turned on, and the other MAC CE is used to instruct the periodic activation of BWP to be turned off. As another implementation method, a MAC CE can also be used to indicate the periodic activation of the BWP, and also indicate the time information for closing the periodic activation of the BWP. For example, in the above MAC CE for instructing to turn on the periodic activation of BWP, it can also carry time information for instructing to turn off the periodic activation, such as the number of cycles, so that the BWP is turned off after the periodic activation reaches the number of cycles The periodic activation of the BWP, for example, can also carry the time period for enabling the periodic activation function, so that the periodic activation of the BWP is turned off after the time period is reached.

It should be noted that the above-mentioned time information (such as the number of cycles, the duration of turning on the periodic activation function, etc.) used to indicate that the periodic activation is turned off can be carried in the MAC CE or the configuration information carried in the above step 201. middle.

In the second implementation method, the first activation time of the BWP is related to the configuration information in the foregoing step 201 .

The terminal device enables periodic activation of the BWP according to the configuration information. Alternatively, it can be understood that the configuration information instructs the terminal device to enable the function of periodically activating the BWP, or it can be understood that the configuration information instructs the terminal device to activate the above-mentioned BWP for the first time.

As an implementation method, the configuration information itself (eg, through the name of the configuration information) may be used to indicate that the periodic activation of the BWP is turned on. As another implementation method, the configuration information can also carry an indication information (this embodiment of the present application also refers to the indication information as the first indication information), and the indication information can be used to indicate that the periodic activation of the BWP is enabled. .

As a first implementation method, after receiving the configuration information, the terminal device immediately activates the BWP for the first time according to the configuration information or the above-mentioned indication information carried in the configuration information.

As a second implementation method, the above configuration information also carries second time information, where the second time information is used to indicate the time period from the first activation of the BWP to a second time, where the second time is the time when the above configuration information is received, or Preset or preconfigured reference time points. That is, after receiving the configuration information, the terminal device activates the BWP for the first time at a specific moment (the duration of the moment from the second time is specified by the second time information). Or, the second time information is used to indicate the time point when BWP is activated for the first time, that is, the second time information indicates an absolute time point, then after the terminal device receives the configuration information, at a specific moment (this moment is determined by the second time information specified) to activate the BWP for the first time.

As a third implementation method, the configuration information also carries the length of the first period and the first duration, where the first duration is used to indicate the length of the time window in which the BWP is allowed to be periodically activated in one first period. The length of the first period may be smaller than the length of the first period. Optionally, the configuration information also carries the number of the first period. After receiving the configuration information, the terminal device can determine the first activation time of the BWP according to the first period. For example, the starting position of the first activation of the first cycle is taken as the first activation time of the BWP (for example, refer to the example diagram of BWP autonomous handover shown in FIG. 6( a )). For another example, the time position separated by a set distance from the start position of the first start of the first cycle is taken as the first activation time of the BWP (for example, refer to the example diagram of BWP autonomous switching shown in FIG. 6( b )). Wherein, the starting position of the first startup of the first cycle may be predefined, or pre-configured, or carried by the configuration information in the foregoing step 201, or notified by another message. Moreover, based on this implementation method, since the first period and the first period are configured in addition to the activation period and the activation duration of the BWP, the terminal device can execute the execution within the time window indicated by the first period of each first period. Periodic activation of BWP, the periodic activation of BWP is not performed outside the time window indicated by the first duration of each first period. Or it can be understood that by configuring the first period and the first duration, the time range of the periodic activation of the BWP with the autonomous switching function is narrowed, so as to realize the periodic activation of the BWP with the autonomous switching function within a specific time window, while Other normal services are performed outside other time windows. For example, referring to FIG. 6(a) or FIG. 6(b), after configuring the first period and the first duration, within the time window indicated by the first duration, if the activation period of BWP5 is reached, the BWP5 is activated, Outside the time window indicated by the first duration, if the activation period of the BWP5 is reached, the BWP5 is also not activated. It should be noted that the starting position of the time window indicated by the first duration in the first period may be the same as the starting position of the first period (for example, refer to FIG. 6(a)), or the starting position of the time window may be the same as the starting position of the first period. The starting position of the first cycle is separated by a first distance (eg, refer to FIG. 6(b) ), and the first distance is preset or preconfigured. It can be understood that, based on this implementation method, the above-mentioned step 202 is specifically: according to the activation period of the BWP, the activation duration, the first period and the first duration, periodically activating the BWP within the time window of the first period.

It should be noted that, the length of the first period and the first duration in the third implementation method above may also be carried in the first message in the first implementation method above. That is, instead of carrying the length of the first cycle and the first duration in the configuration information in the above step 201, the length and the first duration of the first cycle are carried in the above-mentioned first message. Optionally, the first message may also carry the number of the first period. For the meaning and usage of the length of the first period, the first duration, and the number of the first period, reference may be made to the specific description in the third implementation method above, and details are not repeated here.

As a fourth implementation method, the configuration information also carries the length of the first period and the number of times that the BWP is periodically activated in a first period. Optionally, the configuration information also carries the number of the first period. After receiving the configuration information, the terminal device can determine the first activation time of the BWP according to the first period. For example, the starting position of the first activation of the first cycle is taken as the first activation time of the BWP (for example, refer to the example diagram of BWP autonomous handover shown in FIG. 7( a )). For another example, the time position that is separated from the start position of the first start of the first cycle by a set distance (also referred to as the second duration in this embodiment of the present application) is used as the first activation time of the BWP (for example, refer to FIG. 7(b) . BWP autonomous switching example diagram). Wherein, the starting position of the first startup of the first cycle may be predefined, or pre-configured, or carried by the configuration information in the foregoing step 201, or notified by another message. And, based on this implementation method, since the first period and the number of times the BWP is periodically activated in one first period are configured in addition to the BWP activation period and the activation duration, the terminal device can The number of BWP periodic activations to perform periodic activation of BWP. Alternatively, it can be understood that by configuring the first period and the number of times of periodic activation of the BWP in a first period, the number of times of periodic activation of the BWP with the autonomous handover function is reduced. For example, referring to FIG. 7(a) or FIG. 7(b), after configuring the first cycle and the number of BWP periodic activations in a first cycle (taking the configured number of times as 1 as an example), then in each Only one BWP5 is activated in the first cycle, and when the first cycle is not configured and the number of BWP periodic activations in one first cycle is not configured, the number of times the BWP5 is activated is doubled. It can be understood that, based on this implementation method, the above-mentioned step 202 is specifically: according to the activation period of the BWP, the activation duration, the first period, and the number of times that the BWP is periodically activated in a first period, in the first period, the period Activates BWP sexually.

It should be noted that, the length of the first period and the number of times of BWP periodic activation in one first period in the fourth implementation method may also be carried in the first message in the first implementation method above. That is, the configuration information in the above step 201 does not carry the length of the first period and the number of times that the BWP is periodically activated in a first period, but carries the length of the first period and the number of times in a first period in the first message. The number of times the BWP is periodically activated. Optionally, the first message may also carry the number of the first period. For the length of the first period, the number of times the BWP is periodically activated in a first period, and the meaning and usage method of the number of the first period, reference may be made to the specific description in the foregoing fourth implementation method, and details are not repeated here.

A method for implementing the configuration information in the foregoing step 201 will be described below with reference to a specific example. It can be understood that, the configuration information in step 201 may also have other implementation methods, which are not limited in the present invention.

For example, it is currently defined that a maximum of 4 uplink BWPs are configured for a terminal device. If the uplink BWP with the autonomous handover function provided by the embodiment of the present application needs to be added on this basis, the uplink BWP can be added by the following definitions:

Among them, the initial BWP is configured by the initialUplinkBWP, which is used by the UE to receive the remaining minimum system information (RMSI) and other system information (Other system information, OSI) to initiate random access, etc.; the dedicated BWP is configured by uplinkBWP-ToAddModList, using For data service transmission; firstActiveUplinkBWP-Id is used to configure the first activated BWP. uplinkBWP-ToReleaseList indicates the additional uplink BWP to be released. pusch-ServingCellConfig represents a non-BWP-specific uplink physical shared channel (Physical Uplink Shared Channel, PUSCH) related parameters. carrierSwitching contains related parameters of SRS carrier switching configuration. For the meanings of the parameters other than Autonomous-BWP-r17 in the above configuration items, reference may also be made to the relevant descriptions in the standard 3GPP TS38.331.

Autonomous-BWP-r17 is a newly added BWP with autonomous switching function. BWP-Uplink contains the configuration information of the BWP, and SetupRelease{} represents parameter reference, similar to function calls in programming languages.

As an implementation method, the value of the BWP ID can be expanded from 4 to 5. Under this implementation method, the definition of BWP-Uplink is as follows:

where maxNrofBWPs is expanded from 4 to 5.

As another implementation method, a BWP ID can be redefined to specifically describe the BWP with switching function. Under this implementation method, the definition of BWP-Uplink is as follows:

The BWP-Autonomous-Id is the ID of the BWP with the switching function.

The value of maxNrof AutonomousBWPs is greater than or equal to 1.

By extending the BWP ID or redefining the BWP ID above, a BWP with a switching function can be defined.

Further, taking the activation period of the BWP, the activation duration of the BWP and the time information for indicating the first activation of the BWP carried in the configuration information of the above step 201 as an example, the configuration parameters of the BWP can be configured as follows:

BWP-UplinkCommon::= SEQUENCE{

genericParameters BWP,

}

Among them, genericParameters contains the parameters that need to be configured for each BWP, including: subcarrier spacing, cyclic prefix (Cyclic Prefix, CP) and the frequency domain location and bandwidth of the BWP.

The BWP-SwitchTimer is used to indicate that the BWP is activated for the first time within a certain time period after receiving the configuration information. In an optional embodiment, the value of the time period is one of 1 to 60. BWP-TransmissionDuration is used to indicate the activation duration of the BWP, and in an optional embodiment, its value is one of 1 to 24. BWP-TransmissionPeriod is used to indicate the length of the activation period of the BWP, and in an optional embodiment, the value is one of 5, 8, 10, 12, . . . The unit of the value of the above three parameters can be any one of time unit such as time domain symbol, time slot, microsecond, millisecond, second, minute, and hour. The value units of the above three parameters may be different from each other, or may be the same, which is not limited in this application.
