For convenience of understanding, some contents related to the embodiments of the present application are described below:

1. eXtended Reality (XR) services.

XR traffic includes Augmented Reality (AR) traffic, virtual Reality (VR) traffic, and MR (Mixed AR and VR) traffic.

The XR service can adopt an H.264 coding technology to realize image data compression and achieve the purposes of saving flow and ensuring image quality. XR services may include the following three types of image frames:

an I-frame (Intra-coded picture), which is a complete image frame and can be generated and presented independently of other frames;

a P frame (Predicted picture) which contains only image change information with respect to a previous frame, and a receiving side needs to combine the previous frame to generate a current frame and complete display on a receiving terminal;

b-frames (Bidirectional predicted pictures) indicating the motion information of the current frame with respect to the previous and following frames. The receiving side needs to combine the previous frame and the following frame to generate the current frame.

The former frame and the latter frame are ordered according to the frame presentation time or the image acquisition time of the source end, the actual sending and receiving time may be adjusted according to the image decoding time of the receiver, for example, the sender may send according to the image frame decoding time sequence of the receiver.

XR traffic has periodic image frames arriving, e.g., 30, 60, or 120 frames per second, including I-frames, P-frames, and B-frames, where I-frames exhibit periodicity, with several P-frames and B-frames between two adjacent I-frames. An example of an image frame arrival for an XR service is shown in fig. 2. In fig. 2, one frame set (GoP) includes 12 image frames including 1I frame and several P frames and B frames.

Different frame types correspond to different frame encoding methods, resulting in different degrees of image compression. The compression degree of the I frame is low, the compression degree of the P frame is moderate, and the compression degree of the B frame is highest. Thus, the amount of data for the I frame is the largest, the amount of data for the P frame is centered, and the amount of data for the B frame is the smallest. Due to the different data amount of the I frame, the P frame and the B frame, the required operating frequency bandwidth (which may also be referred to as operating bandwidth or bandwidth) is different when the same image frame transmission delay is satisfied, wherein the operating frequency bandwidth required for the I frame is the largest, the operating frequency bandwidth required for the B frame is the smallest, and the frequency bandwidth required for the B frame is the smallest.

The XR image has two transmission modes, a transmission mode based on frame slice combination and a transmission mode based on GoP.

A data frame is cut into a plurality of data blocks, then the blocks of the plurality of image frames are scattered and combined into a plurality of data blocks for transmission, the aim that the XR service data flow is smooth among the plurality of image frames is achieved, the method greatly reduces flow fluctuation caused by the difference of the data quantity of I frames, P frames and B frames, but obviously increases the transmission delay of the image frames due to the cross transmission among the image frames;

the transmission mode based on GoP: according to the periodicity characteristic of the video stream, the video frames are divided into video frame combinations according to the period of the I frame, and an I frame and all the subsequent P frames and B frames before the next I frame form a GoP. The image frames are transmitted and played at a receiving party according to a Frame period, and the time interval between the Frame arrival times of adjacent image frames is one Frame period (Frame period). The GoP-based transmission mode avoids mixed transmission among image frames, so that the generated image frames are transmitted in time. The frame data rate fluctuates due to the difference in the degree of compression between I, P, and B frames.

2. Bandwidth Part (BWP) of New Radio (NR).

In order to balance the bandwidth requirement of the service and the power consumption of the terminal, the NR may further configure one or more BWPs of the terminal on one carrier, and on the BWPs, further configure other wireless resources that the UE needs to use, such as a Synchronization Signal and PBCH block (SSB), a Control Resource Set (core Set), a Physical Uplink Control Channel (PUCCH), a Physical Random Access Channel (PRACH), and broadcast system messages, etc. According to the current protocol, a UE can only have one active BWP per carrier, i.e. the current BWP. The UE may switch from one BWP to another BWP according to network configuration, for example, based on received Radio Resource Control (RRC) signaling, BWP handover signaling carried by Physical Downlink Control Channel (PDCCH) signaling, or based on a BWP Inactivity Timer configured in the network, trigger a handover from a current BWP to an initial BWP upon timeout.

Through a BWP switching mechanism, switching to BWP with narrow bandwidth can be performed when the data rate required by the terminal service is low, so as to reduce the power consumption of UE; and when the data rate required by the service of the terminal is high, switching to the BWP with large bandwidth can be carried out under the instruction of the network.

3. NR Secondary Cell (SCell) dormant state (dormant).

Through Carrier Aggregation (CA) technology, multiple carriers can be configured and activated for a UE, increasing the operating bandwidth of the UE. But the UE rate requirements fluctuate, and factors affecting the rate fluctuation requirements include: the service of the UE changes, the bandwidth of the transmission network is influenced, the data rate of the service fluctuates, and the like. When the bandwidth required by the UE becomes smaller, the SCell of the UE may be switched from the non-dormant BWP to the dormant BWP, and enter the SCell dormant state. The non-dormant BWP is used for BWP of data transmission, and the UE needs to prepare for data reception; on the dormant BWP, the UE does not need to perform PDCCH detection and prepare data reception, which can reduce power consumption.

Entering SCell dormant state means that the UE switches from non-dormant BWP to dormant BWP, and vice versa for leaving SCell dormant state. Entering and leaving SCell sleep state may be indicated by PDCCH.

The embodiments of the present application are described in detail below with reference to the accompanying drawings through some embodiments and application scenarios thereof.

Referring to fig. 3, fig. 3 is a flowchart of an operating bandwidth adjustment method provided in an embodiment of the present application. The operating bandwidth adjustment method of fig. 3 may be performed by a terminal. As shown in fig. 3, the method for adjusting the operating bandwidth may include the following steps:

step 301, the terminal obtains the adjustment rule of the working bandwidth.

In a specific implementation, optionally, the adjustment rule may be configured by a network side device, generated by the terminal, or predefined by a protocol. That is, the terminal may obtain the adjustment rule by receiving, generating, or reading from the protocol, such as: and the terminal receives the adjustment rule sent by the network side equipment. In the case that the adjustment rule is predefined by a network side device configuration or protocol, the adjustment rule may be understood as a preconfigured adjustment rule. It should be noted that, the terminal and the network side device have a consistent understanding of the adjustment rule of the working bandwidth of the terminal, so that the reliability of service transmission of the terminal can be ensured.

The adjustment rule may correspond to P services, where P is a positive integer, where the adjustment rule corresponds to a certain service and may be understood as: the adjustment rule may be applicable to the service, that is, when the terminal receives the service, the working bandwidth of the terminal may be adjusted according to the adjustment rule, so that the working bandwidth of the terminal adapts to the requirement of the service for the working bandwidth. In implementation, the P services may be part or all of the services of the terminal. Optionally, the P services may be a first service of the terminal, and data arrival of the first service has periodicity, and in an implementation, the first service may be an XR service, but is not limited thereto.

And step 302, the terminal executes the adjustment operation of the working bandwidth of the terminal according to the adjustment rule.

In a specific implementation manner, the terminal may directly adjust the working bandwidth of the terminal by using the adjustment rule; in another implementation manner, the terminal may adjust the working bandwidth of the terminal by using the adjustment rule only when a certain condition is satisfied, otherwise, the terminal may adjust the working bandwidth of the terminal by using a manner in the related art, for example, adjust the working bandwidth of the terminal based on a PDCCH signaling indication of a network side device.

In the case of adjusting the working bandwidth of the terminal by using the adjustment rule, it can be understood that the actual working bandwidth of the terminal is matched with the adjustment rule, so that the reliability of the service transmission of the terminal can be improved.

According to the working bandwidth adjusting method, the terminal can actively adjust the working bandwidth of the terminal according to the pre-acquired adjusting rule of the working bandwidth, so that the signaling overhead of the working bandwidth adjustment can be reduced, and the reliability of the working bandwidth adjustment can be improved.

Optionally, in a case that the adjustment rule corresponds to a first service, the adjustment rule may be determined based on service information of the first service, where the service information includes at least one of: arrival time offset information of data, arrival period information of data, and type information of data.

The data arrival of the first service has periodicity, and the arrival time offset information of the data and the arrival period information of the data can be used for determining the arrival time of the data.

The first service may include at least one data type. In the case where the first service includes two or more data types, it is considered that the amount of data of different data types may be different, resulting in different required operating bandwidths, and therefore, in determining the adjustment rule, type information of data may be introduced.

In this case, the adjustment rule may be used to periodically adjust the operating bandwidth of the terminal. The adjustment rule may include adjustment period information and adjustment time offset information of the operating bandwidth.

In order to adapt the working bandwidth of the terminal to the requirement of the first service for the working bandwidth, the adjustment period may be matched with a data arrival period of the first service, and the adjustment period is matched with the data arrival period, which may be understood as: equal or approximately equal. In practical applications, the time granularity of the configuration of the adjustment period and the data arrival period may be the same or different, for example, the time granularity of the adjustment period may be absolute time, such as millisecond, and the time granularity of the data arrival period may be time unit, such as time slot or symbol.

Further, in a case that the first service includes two or more data types, in an adjustment period, the operating bandwidth of the terminal may adapt to requirements of different types of data on the operating bandwidth, corresponding to different types of data that the first service arrives.

Optionally, the first service is an extended reality XR service, and the XR service includes I frame data, P frame data, and B frame data.

As can be seen from the foregoing, the working bandwidth required by I frame data > the working bandwidth required by P frame data > the working bandwidth required by B frame data, and in order to make the working bandwidth of the terminal adapt to the requirement of the XR service on the working bandwidth, in any adjustment period, the adjustment rule may adjust the working bandwidth of the terminal to satisfy: the working bandwidth of the terminal when I frame data arrives is larger than the working bandwidth of the terminal when P frame data arrives is larger than the working bandwidth of the terminal when B frame data arrives.

In the embodiment of the present application, optionally, the adjustment rule may include at least one of the following:

the state of the auxiliary cell of the terminal is switched between a dormant state and a non-dormant state;

second configuration information for periodic handover of a bandwidth part BWP of the serving cell of the terminal.

The state of the secondary cell is switched between a dormant state and a non-dormant state, that is, the state of the secondary cell may be represented as a dormant state or a non-dormant state.

The first configuration information may configure the secondary cell of the terminal to periodically switch between a dormant state and a non-dormant state, that is, the secondary cell of the terminal is configured to periodically enter and leave the dormant state, so as to adjust the working bandwidth of the terminal.

In specific implementation, the first configuration information may configure a switching period and a time offset of a state of the secondary cell of the terminal, so that the time when the secondary cell of the terminal enters the non-dormant state matches the arrival of the service data.

For ease of understanding, see FIG. 4a. In fig. 4a, the first service is exemplified as XR service.

As shown in fig. 4a, the Primary Component Carrier (PCC), i.e. the Primary cell, is always in a non-dormant state. For a Secondary Component Carrier (SCC), that is, an SCell, when an image frame arrives, both SCC1 and SCC2 are in a non-sleep state to increase an operating bandwidth of a terminal; when the current image frame is transmitted and the next image frame is not reached, SCC1 and SCC2 are in a sleep state (dormant state) to reduce power consumption of the terminal.

In addition, considering that the data amount of the I frame is large and the transmission time is long, as shown in fig. 4a, the time length of SCC1 and SCC2 in the non-sleep state when the I frame arrives may be longer than the time length of SCC1 and SCC2 in the non-sleep state when the P frame arrives.

The second configuration information may configure the terminal to periodically perform BWP handover of a serving cell, so as to implement adjustment of an operating bandwidth of the terminal.

In a specific implementation, the first configuration information may configure a switching period and a time offset of a BWP of a serving cell of the terminal, so that when there is service data arriving, the serving cell switches to the BWP with a large operating frequency bandwidth, and when the next service data does not arrive after the current service data is completely transmitted, the serving cell switches to the BWP with a small operating frequency bandwidth.

For ease of understanding, see FIG. 4b. In fig. 4b, the first service is the XR service, the terminal includes BWP0 and BWP1, and the operating bandwidth of BWP1 is greater than that of BWP 0.

As shown in fig. 4b, when an image frame arrives, BWP1 is in an active (active) state, and BWP0 is in an inactive (inactive) state, so as to increase the operating bandwidth of the terminal; when the current image frame is transmitted and the next image frame does not arrive, BWP0 is in an active state, BWP1 is in an inactive (inactive) state, so as to reduce the power consumption of the terminal.

Optionally, the terminal performs an operation of adjusting the working bandwidth of the terminal according to the adjustment rule, where the operation includes at least one of:

the terminal periodically switches the state of a target auxiliary cell of the terminal according to the first configuration information;

and the terminal periodically switches the target BWP of the target serving cell of the terminal according to the second configuration information.

That is to say, the terminal may adjust the working bandwidth of the terminal by periodically switching the state of the target secondary cell of the terminal; or, the terminal may implement the adjustment of the operating bandwidth of the terminal by periodically switching the target BWP of the target serving cell of the terminal.

It can be understood that the handover of the state of the target secondary cell of the terminal matches the first configuration information; the handover of the target BWP of the target serving cell of the terminal is matched with the second configuration information.

The first configuration information and the second configuration information are explained below, respectively.

1) The first configuration information

In this embodiment, the first configuration information may have the following expression form:

expression form one

Optionally, the first configuration information includes a first switching period and a first time offset; the first configuration information may satisfy: the time of the target auxiliary cell of the terminal entering the non-dormant state is matched with the arrival time of the first type data of the first service;

the first type of data is I frame data, P frame data or B frame data; the target secondary cell is a first secondary cell, a second secondary cell or a third secondary cell.

In a specific implementation, matching the first time (i.e. the time when the target secondary cell of the terminal enters the non-dormant state) with the second time (i.e. the arrival time of the first type of data of the first service) may be understood as: the first time is completely aligned with the second time, namely the first time is equal to the second time; or, the first time and the second time are separated by a second time length, the first time may be before or after the second time, and the second time length is configured by the network side device or predefined by the protocol.

The target secondary cell may correspond to the first type of data, that is, which secondary cells specifically included in the target secondary cell are determined based on the expression form of the first type of data, and for different expression forms of the first type of data, the number of secondary cells included in the target secondary cell and/or the number of secondary cells included in the target secondary cell may be different.

Optionally, in a case that the first type of data is I-frame data, the target secondary cell may be the first secondary cell; in a case that the first type of data is P frame data, the target secondary cell may be the second secondary cell; in a case where the first type of data is B frame data, the target secondary cell may be the third secondary cell. In this case, the first secondary cell may include a greater number of secondary cells than the second secondary cell, and the second secondary cell may include a greater number of secondary cells than the third secondary cell.

Optionally, the first configuration information may include a first handover configuration corresponding to a state of the secondary cell.

The first handover configuration may be applicable to a handover of a state of a secondary cell of the terminal. In the embodiment of the present application, the switching configuration may include, but is not limited to, a switching period and a time offset.

Optionally, the first switching configuration may satisfy at least one of:

when the first type of data is I frame data, the first switching configuration comprises a first sub-switching configuration corresponding to the state of the first auxiliary cell;

when the first type of data is P frame data, the first switching configuration comprises a second sub-switching configuration corresponding to the state of the second auxiliary cell;

when the first type of data is B frame data, the first handover configuration includes a third sub-handover configuration corresponding to a state of the third secondary cell.

The first sub-handover configuration is applicable to handover of a state of the first secondary cell. For the arrival of I frame data, the terminal may switch the state of the first secondary cell according to the first sub-handover configuration, so that the first secondary cell enters a non-dormant state.

The second sub-handover configuration is applicable to handover of a state of the second secondary cell. In a specific implementation, for the arrival of P frame data, the terminal may switch the state of the second secondary cell according to the second sub-handover configuration, so that the second secondary cell enters a non-dormant state.

The third sub-handover configuration is applicable to handover of a state of the third secondary cell. In a specific implementation, for the arrival of B frame data, the terminal may switch the state of the third secondary cell according to the third sub-handover configuration, so that the third secondary cell enters a non-dormant state.

It should be noted that the first sub-handover configuration, the second sub-handover configuration, and the third sub-handover configuration may be the same or different, and may be determined specifically according to actual situations, which is not limited in this embodiment of the present application.

Optionally, the first sub-handover configuration may include a handover configuration corresponding to states of N1 secondary cells, the second sub-handover configuration includes a handover configuration corresponding to states of N2 secondary cells, and the third sub-handover configuration includes a handover configuration corresponding to states of N3 secondary cells; wherein N1, N2 and N3 are positive integers, N1 is greater than or equal to N2, and N2 is greater than or equal to N3.

In this optional embodiment, the first secondary cell includes N1 secondary cells, the second secondary cell includes N2 secondary cells, and the third secondary cell includes N3 secondary cells.

For ease of understanding, see FIG. 5a. In fig. 5a, the first service is exemplified as an XR service.

As shown in fig. 5a, the PCC is always in a non-dormant state. For the SCC, when an I frame arrives, both SCC1 and SCC2 are in a non-sleep state, so that the working bandwidth of the terminal adapts to the working bandwidth required by the I frame; when a P frame arrives, SCC1 is in a non-sleep state, and SCC2 is in a sleep state, so that power consumption of the terminal can be reduced while ensuring that the working bandwidth of the terminal adapts to the working bandwidth required by the P frame; when the current image frame is transmitted and the next image frame is not reached, the SCC1 and the SCC2 are in a sleep state to reduce the power consumption of the terminal.

In addition, considering that the data amount of the I frame is large and the transmission time is long, as shown in fig. 5a, the time duration that SCC1 and SCC2 are in the non-sleep state when the I frame arrives may be longer than the time duration that SCC1 is in the non-sleep state when the P frame arrives.

As can be seen from the foregoing, the adjustment period of the operating bandwidth of the terminal may be different from the time granularity of the data arrival period, and due to such difference, the time when the target secondary cell of the terminal enters the non-dormant state may not match the arrival time of the first type data of the first service in some adjustment periods. For this situation, the time when the target secondary cell of the terminal enters the non-dormant state may be re-matched with the arrival time of the first type of data of the first service in the following manner, so as to improve the reliability of service transmission.

Optionally, the first configuration information includes a first switching period and a first time offset;

after the terminal periodically switches the state of the target secondary cell of the terminal according to the first configuration information, the method further includes:

under the condition that the time of a target auxiliary cell of the terminal entering a non-dormant state is not matched with the arrival time of first-class data of a first service, the terminal determines a first target time offset;

and the terminal periodically switches the state of the target secondary cell of the terminal according to the first switching period and the first time offset.

In this optional embodiment, the terminal may re-determine a time offset each time it is detected that the time when the target secondary cell of the terminal enters the non-dormant state is not matched with the arrival time of the first type of data of the first service, and then periodically switch the state of the target secondary cell of the terminal according to the re-determined time offset.

In specific implementation, the terminal may obtain the redetermined time offset by adjusting the current time offset according to the current mismatch condition, or may directly generate a new time offset according to the current mismatch condition. That is, the re-determination of the time offset may be dependent on the current time offset or may not be dependent on the current time offset, which may be determined according to actual situations, and this is not limited in this embodiment of the application.

It should be noted that, the terminal periodically switches the state of the target secondary cell of the terminal according to the redetermined time offset, so that the time when the target secondary cell of the terminal enters the non-dormant state is newly matched with the arrival time of the first type of data of the first service.

Expression form two

Optionally, the first configuration information includes a first configuration template and first sub-configuration information;

the period of the first configuration template is Z times of the data arrival period of the first service, and Z is a positive integer;

the first sub-configuration information includes a third switching period and a third time offset, the third switching period is less than or equal to the period of the first configuration template, and the first sub-configuration information satisfies: and the time of the target auxiliary cell of the terminal entering the non-dormant state is matched with the arrival time of the first type of data of the first service.

In specific implementation, the terminal may periodically switch the state of the target secondary cell of the terminal according to the first configuration template. In each first configuration template, the terminal may periodically switch the state of the target secondary cell of the terminal according to the first sub-configuration information.

Because the period of the first configuration template is an integral multiple of the data arrival period of the first service, the time point of the target auxiliary cell of the terminal, which is adjusted by the first terminal in each template, entering the non-dormant state is matched with the arrival time of the corresponding data frame again, so that the time of the target auxiliary cell of the terminal entering the non-dormant state is always matched with the arrival time of the first type of data of the first service, and the reliability of service transmission is improved.

2) The second configuration information

In this embodiment, the second configuration information may have the following expression form:

expression 1

Optionally, the second configuration information includes a second switching period and a second time offset; the second configuration information satisfies: the time of the target BWP of the target serving cell of the terminal entering the activated state is matched with the arrival time of the second type data of the first service;

wherein the second type data is I frame data, P frame data or B frame data, and the target BWP is a first BWP, a second BWP or a third BWP.

In a specific implementation, the matching of the third time (i.e. the time when the target BWP of the target serving cell of the terminal enters the active state) and the fourth time (i.e. the arrival time of the second type data of the first service) can be understood as: the second time is completely aligned with the fourth time, namely the second time is equal to the fourth time; or, the second time and the fourth time are separated by a third duration, the second time may be before or after the fourth time, and the third duration is configured by the network side device or predefined by a protocol.

The target BWP may correspond to the second type of data, i.e. the specific representation of the target BWP is determined based on the representations of the first type of data, and the target BWP may be different for different representations of the first type of data.

Alternatively, in the case where the first type of data is I-frame data, the target BWP may be the first BWP; in a case where the first type of data is P frame data, the target BWP may be the second BWP; in a case where the first type data is B frame data, the target BWP may be the third BWP. In this case, the operating bandwidth of the first BWP is greater than the operating bandwidth of the second BWP, which is greater than the operating bandwidth of the third BWP.

The target serving cell may be any serving cell of the terminal.

Optionally, the second configuration information includes a second handover configuration corresponding to BWP.

The second handover configuration may be applicable to handover of BWP of the terminal.

Optionally, the second handover configuration satisfies at least one of:

when the second type data is I-frame data, the second switching profile includes a switching profile corresponding to the first BWP (hereinafter referred to as a fourth sub-switching profile);

when the second type data is P frame data, the second switching profile includes a switching profile corresponding to the second BWP (hereinafter referred to as a fifth sub-switching profile);

when the second type data is B frame data, the second switching profile includes a switching profile corresponding to the third BWP (hereinafter referred to as a sixth sub-switching profile).

The fourth sub-handover configuration is applicable for handover of the first BWP. For the arrival of I-frame data, the terminal may switch to the first BWP, i.e., activate the first BWP, according to the fourth sub-switching configuration.

The fifth sub-handover configuration is applicable for handover of the second BWP. In a specific implementation, for the arrival of P frame data, the terminal may switch to the second BWP according to the fifth sub-switching configuration, that is, activate the second BWP.

The sixth sub-handover configuration is applicable for handover of the third BWP. In a specific implementation, for the arrival of B frame data, the terminal may switch the third BWP according to the sixth sub-switch configuration, that is, activate the third BWP.

It should be noted that the fourth sub-switching configuration, the fifth sub-switching configuration, and the sixth sub-switching configuration may be the same or different, and may be determined specifically according to actual situations, which is not limited in this embodiment of the present application.

Optionally, the bandwidth of the first BWP is M1, the bandwidth of the second BWP is M2, and the bandwidth of the third BWP is M3; wherein M1 is greater than or equal to M2, and M2 is greater than or equal to M3.

For ease of understanding, see FIG. 5b. In fig. 5b, the first service is the XR service, the terminal includes BWP0, BWP1 and BWP2, and the operating bandwidth of BWP2 > the operating bandwidth of BWP1 > the operating bandwidth of BWP 0.

As shown in fig. 5b, when an I-frame arrives, BWP2 is in the active state, and BWP0 and BWP1 are in the inactive state, so that the working bandwidth of the terminal is adapted to the working bandwidth required by the I-frame; when a P frame arrives, BWP1 is in an active state, BWP0 and BWP2 are in an inactive state, thus reducing the power consumption of the terminal under the condition of ensuring that the working bandwidth of the terminal adapts to the working bandwidth required by the P frame; when the current image frame is transmitted and the next image frame is not reached, BWP0 is in an active state, and BWP1 and BWP2 are in an inactive state, so as to reduce power consumption of the terminal.

As can be seen from the foregoing, the adjustment period of the working bandwidth of the terminal may have different time granularity from the data arrival period, and due to this difference, it may cause that in some adjustment periods, the time at which the target BWP of the target serving cell of the terminal enters the active state does not match the arrival time of the second type data of the first service. For this case, the time when the target BWP enters the active state may be re-matched with the arrival time of the second type of data in the following manner, thereby improving the reliability of traffic transmission.

Optionally, the second configuration information includes a second switching period and a second time offset;

under the condition that the time of the target BWP of the target serving cell of the terminal entering an activated state is not matched with the arrival time of the second type data of the first service, the terminal determines a second target time offset;

and the terminal periodically switches the target BWP of the target serving cell of the terminal according to the second switching period and the second target time offset.

In this alternative embodiment, the terminal may re-determine a time offset each time it is detected that the time at which the target BWP of the target serving cell of the terminal enters the active state does not match the arrival time of the second type of data of the first service, and then periodically switch the target BWP of the target serving cell of the terminal according to the re-determined time offset.

In specific implementation, the terminal may obtain the redetermined time offset by adjusting the current time offset according to the current mismatch condition, or may directly generate a new time offset according to the current mismatch condition. That is, the re-determination of the time offset may or may not depend on the current time offset, which may be determined according to actual situations, and is not limited in this embodiment of the present application.

It should be noted that, when the terminal periodically switches the target BWP of the target serving cell of the terminal according to the redetermined time offset, the time at which the target secondary cell of the terminal enters the non-dormant state may be re-matched with the arrival time of the first type data of the first service.

Expression form 2

Optionally, the second configuration information includes a second configuration template and second sub-configuration information;

the period of the second configuration template is Z times of the data arrival period of the first service, and Z is a positive integer;

the second sub-configuration information includes a fourth switching period and a fourth time offset, the fourth switching period is less than or equal to the period of the second configuration template, and the second sub-configuration information satisfies: the time when the target BWP of the target serving cell of the terminal enters the active state is matched with the arrival time of the second type data of the first service.

In a specific implementation, the terminal may periodically switch the target BWP of the target serving cell of the terminal according to the second configuration template. In each of the second configuration templates, the terminal may periodically switch a target BWP of a target serving cell of the terminal according to the first sub-configuration information.

Because the period of the second configuration template is an integral multiple of the data arrival period of the first service, the time point of the target BWP adjusted by the first terminal in each template entering the active state is re-matched with the arrival time of the corresponding data frame, so that the time of the target BWP of the target serving cell of the terminal entering the active state can be ensured to be always matched with the arrival time of the second type of data of the first service, and the reliability of service transmission is improved.

The working bandwidth adjusting method in the embodiment of the application can be implemented independently, and can also be implemented by combining the working bandwidth adjusting method in the related technology.

Optionally, the terminal performs an operation of adjusting the working bandwidth of the terminal according to the adjustment rule, where the operation includes:

under the condition that the terminal does not receive a first PDCCH instruction before a first time point, the terminal executes the adjustment operation of the working bandwidth of the terminal according to the adjustment rule;

wherein the first time point is matched with the data arrival time of a first service; the first PDCCH instruction is used for instructing the terminal to adjust the working bandwidth.

And under the condition that the terminal receives the first PDCCH instruction before the first time point, the terminal can ignore the adjustment rule and directly execute the adjustment operation of the working bandwidth of the terminal according to the first PDCCH instruction.

The first time point is matched with the data arrival time of the first service, which can be understood as follows: the first time point is completely aligned with the data arrival time of the first service, or is separated by a preset time length.

The first time point may be predefined by a network side device configuration or protocol. Optionally, the first time point may be located after a reference time point, and the first time point is separated from the reference time point by a first time length.

The reference time point and the first time length may be predefined by a network side device configuration or a protocol. Optionally, the reference time point may be a start time or an end time of a PDCCH monitoring window.

In a specific implementation, the first duration may be configured by a timer. Optionally, the terminal may start a timer at the reference time point, where a duration of the timer is the first duration; under the condition that the timer is overtime, the terminal can execute the operation of adjusting the working bandwidth of the terminal according to the adjustment rule; if the terminal receives the first PDCCH instruction before the timer expires, the terminal may perform an operation of adjusting the working bandwidth of the terminal according to the first PDCCH instruction, and stop the timer.

It should be noted that the first time points correspond to data arrival times one to one, that is, for the arrival time of each data, there is a first time point corresponding to each data arrival time, and for the arrival of a certain data, whether to adjust the working bandwidth of the terminal according to the adjustment rule can be determined by whether to receive the detection result of the first PDCCH instruction according to the first time point corresponding to the arrival time of the data.

Through the method, the terminal can adjust the working bandwidth of the terminal according to the adjustment rule and/or the PDCCH instruction for indicating the adjustment of the working bandwidth, so that the flexibility of the adjustment of the working bandwidth can be improved.

It should be noted that, the present embodiment is taken as an embodiment of a network side device corresponding to the embodiment of the method in fig. 3, and therefore, reference may be made to the relevant description in the embodiment of the method in fig. 3, and the same beneficial effects may be achieved. To avoid repetition of the description, the description is omitted.

It should be noted that, various optional implementations described in the embodiments of the present application may be implemented in combination with each other or separately, and the embodiments of the present application are not limited thereto.

For ease of understanding, examples are illustrated below:

in the following example, the adjustment of the operating bandwidth of the terminal based on XR traffic is illustrated.

In this example, considering the arrival periodicity of the XR service image frames, the UE and the base station may be configured to actively adjust the operating frequency bandwidth of the UE based on the arrival time of the image frames, so as to adapt to the requirement of the image frame rate change on the operating frequency bandwidth and reduce the power consumption of the UE as much as possible, including:

the method comprises the steps that a UE is configured to periodically enter and leave a dormant state of an SCell;

pre-configuring the UE to periodically perform BWP handover of a serving cell;

the PDCCH is followed by an indication of the adjustment mode (i.e., the aforementioned adjustment rule) for the operating frequency bandwidth based on the preconfigured periodicity.

The first embodiment is as follows: based on a handover between a preconfigured SCell non-dormant state and SCell dormant state.

One implementation, preconfigures the time for a periodic SCell to enter from dormant state to non-dormant state based on the periodic arrival time of XR image frames, such that when an image frame arrives, the UE automatically causes one or more scells to enter from SCell dormant state to non-dormant state. The network may pre-configure the period and offset at which the SCell sleep state of the UE enters the non-sleep state such that each time the UE brings the SCell sleep state into the non-sleep state matches the arrival time of the image frame data, as shown in fig. 4a.

For another implementation example, when the period and offset of the arrival of the image frame and the period and offset of the SCell switching from the dormant state to the non-dormant state are different due to the configured time granularity of the two, the switching time of the SCell from the dormant state to the non-dormant state and the arrival time of the image frame become no longer matched from matching. The network may use a periodic template for the periodic switching of the UE SCell from the dormant state to the non-dormant state. When the periodic templates are adopted, one template comprises N periodic SCells switched from a dormant state to a non-dormant state and N switching time points switched from the non-dormant state to the dormant state, and the N switching time points correspond to N image frame arrival times; the switching time of the SCell in each template from the dormant state to the non-dormant state is realigned with the corresponding image frame arrival time, so that the phenomenon that the shifting of the switching time of the SCell from the dormant state to the non-dormant state and the arrival time of the image frame are accumulated across templates due to the inconsistency of the time granularity is avoided.

One implementation way configures a list of corresponding scells to be switched from dormant state to non-dormant state according to the type of the image frame, for example:

corresponding to the arrival of the I frame, SCell1, SCell2 and SCell3 are configured to be switched from a dormant state to a non-dormant state;

corresponding to the arrival of the P frame, switching the SCell1 and the SCell2 from the dormant state to the non-dormant state;

corresponding to the arrival of a B frame, SCell1 is not configured for handover from dormant state to non-dormant state.

As shown in fig. 5a, a switching between an adaptive SCell dormant state and a non-dormant state based on frame type (including only I-frames and P-frames) is illustrated, where both SCC1 and SCC2 switch from the dormant state to the non-dormant state corresponding to an I-frame, and only SCC1 switches from the dormant state to the non-dormant state corresponding to a P-frame.

When data transmission of one image frame is finished, an SCell can be preconfigured to be switched into a dormant state, and the dormant state is kept until the next image frame arrives.

Example two: switching based on preconfigured BWP.

The BWP switching is automatically performed according to the arrival time of the image frame, for example, when the image frame arrives, the BWP is switched to the BWP with the large operating frequency bandwidth, and when the data transmission of the image frame is completed and the next image frame does not arrive yet, the BWP is switched to the BWP with the small operating frequency bandwidth, as shown in fig. 4b.

For different requirements of the frame rate of the I/P/B frames, a corresponding BWP is configured, and the operating frequency bandwidth of the BWP may be determined according to the rate requirements of the corresponding image frame. FIG. 5b shows an example, where an I-frame corresponds to a BWP with a large operating frequency bandwidth, a P-frame corresponds to a BWP with a smaller operating frequency bandwidth, and no graphics data is transmitted, the BWP with a smaller operating frequency bandwidth.

Example three: a preconfigured operating frequency bandwidth adjustment mode in combination with the PDCCH indication.

The combination mode is mainly used for avoiding that the dormant state of the SCell is not switched to the non-dormant state in time or one carrier is not switched from the narrow BWP to the wide BWP in time due to PDCCH missed detection, so that XR data transmission cannot be performed normally:

1) A combined use of a handover from a preconfigured automatic SCell dormant state to a non-dormant state and a PDCCH-based dynamic SCell dormant state to a non-dormant state.

Configuring a PDCCH based SCell handover from a dormant state to a non-dormant state. The network is configured with at least one PDCCH detection window, and the ideal time for completing the switching of the SCell from the dormant state to the non-dormant state matches the arrival time of the XR image frame data before each XR image frame data arrives. In order to overcome PDCCH missed detection, which causes the SCell to remain in the dormant state when XR image frame data arrives, the network may pre-configure the UE with a time D1 for switching the SCell from the dormant state to the non-dormant state at the latest with respect to a PDCCH detection window (start or end point) or a pre-configured time point A1, and if a PDCCH indicating switching of the SCell from the dormant state to the non-dormant state is not detected before A1+ D1, the UE immediately or completes switching the SCell from the dormant state to the non-dormant state.

Time D1 may be configured based on a timer that is started at a given point in time (e.g., the PDCCH detection window or a point in time that matches the XR image frame arrival time); if the PDCCH for indicating the switching from the dormant state to the non-dormant state of the SCell is not received when the timer is finished, the UE immediately switches the SCell from the dormant state to the non-dormant state; and if the PDCCH for indicating the switching of the SCell from the dormant state to the non-dormant state is received when the timer runs, immediately switching the SCell from the dormant state to the non-dormant state and stopping the timer.

2) A combination use of PDCCH-based BWP handover and pre-configured-based automatic BWP handover.

The network may configure the UE with a latest handover time A2+ D2 from narrow BWP (original BWP) to wide BWP (target BWP) relative to a given point in time A2 (matching XR image frame data arrival time), at which time the UE should perform or complete a handover from narrow BWP to wide BWP at a time a + D2 if a PDCCH indicating a handover from narrow BWP to wide BWP is not received in time.

Similar to 1), time D2 may be based on a timer configuration, starting a timer at a given point in time (e.g., a PDCCH detection window or a point in time that matches the arrival time of the XR image frame); if no indication is received from the narrow BWP to the wide BWP at the end of the timer, the switch from the narrow BWP to the wide BWP is immediately made.

In this example, the operating frequency bandwidth is adjusted by switching between SCell dormant state and non-dormant state and/or flexible switching BWP based on periodic arrival of XR image frames for the purpose of saving UE power without affecting XR image frame data transmission.
