In order to facilitate a clearer understanding of the technical solutions provided by the embodiments of the present application, some relevant background knowledge is first introduced as follows.

The new BSR format enables UE to report the delay information of uplink data and reduce the quantization error of uplink data volume. In the process of BRS reporting, the delay information quantization of data packets, the quantization of uplink buffer data, And the triggering problem of BSR based on delay information. The new BSR can contain delay information of uplink data and/or lower quantization error, which also means a larger BSR size.

About Rel-15/16BSR:

Rel-15 BSR is currently supported by default. The following types of BSR are included in Rel-15 BSR:

1. Regular BSR is triggered in any of the following situations:

a) A logical channel (LCH) with a higher priority than the current one with data to be sent changes from no data to data to be sent;

b) When all LCHs have no data to send, one LCH becomes available to send data;

c) When the BSR retransmission timer (retxBSR-Timer) times out, at least one LCH still has data to be sent.

2. Periodic BSR (Periodic BSR) is triggered when the periodic BSR sending timer (periodicBSR-Timer) times out.

3. Padding BSR: It is triggered when a Media Access Control (MAC) Protocol Data Unit (PDU) has remaining capacity to accommodate BSR MAC Control Element (MAC CE) after accommodating all data.

An LCH belongs to an LCH group (LCG). The buffer size level (BS) of the BSR is reported in units of LCG. A maximum of 8 LCGs can be configured. Regular BSR can trigger the sending of SR. If no grant is obtained after the last SR is sent, SR retransmission can be triggered.

For regular/periodic BSR, if the UE has more than one LCG with data, use long BSR, otherwise use short BSR.

About the concept of Extended Reality (XR) protocol data unit group (PDU set)

XR is a video service based on low latency and high definition. The media data unit of the current video service is PDU set. A PDU set contains at least one PDU, which is generated by the video source after encoding an image or an image area. After receiving the PDU belonging to a PDU set, the video receiver can decode the video and restore the corresponding image or image area.

To sum up, in the process of UE using the new BSR format to report more detailed information to the base station, it is necessary to consider the balance between reporting and position information. In order to reduce the overhead of position information, the embodiments of the present application provide a BSR reporting method, apparatus, terminal and network-side equipment.

The BSR reporting method provided by the embodiment of the present application is described in detail below in conjunction with the accompanying drawings through some embodiments and their application scenarios. The embodiment of the present application can be applied to situations involving higher-precision buffer information reporting and/or delay information reporting, and can potentially be applied to all service types including XR.

FIG. 4 is a flow chart of a BSR reporting method according to an embodiment of the present application. As shown in FIG. 4 , the method includes step 401; wherein:

Step 401, the terminal generates a BSR of cached data based on first configuration information; the BSR includes reporting information of at least one logical channel group LCG; the first configuration information includes at least one of the following: first information, used to indicate the data volume reporting configuration of the cached data of at least one LCG; second information, used to indicate the delay information reporting configuration of the cached data of at least one LCG.

It should be noted that the embodiments of the present application can be applied to BSR reporting scenarios; the terminals include but are not limited to the types of terminals 11 listed above, and the present application does not limit this.

Since the UE uses the new BSR format to report more detailed information to the base station, it is necessary to consider the reporting and header Inch information balance; in order to reduce the overhead of position information, in this embodiment, the terminal needs to generate a BSR of cache data based on the first configuration information.

Optionally, before the terminal generates a BSR of cached data based on the first configuration information, the terminal needs to receive the first configuration information from a network-side device.

Optionally, after the terminal generates a BSR to be transmitted, the terminal needs to send the BSR to a network side device.

In the BSR reporting method provided in the embodiment of the present application, the terminal generates a BSR for cached data based on the first configuration information. Since the first configuration information involves data volume reporting configuration and/or delay information reporting configuration, the BSR generated by the terminal based on the data volume reporting configuration and/or delay information reporting configuration can achieve a balance between the BSR reporting information and the position information, and can reduce the position information overhead.

Optionally, the terminal generates a BSR of cached data based on the first configuration information, specifically including the following steps:

Step a: The terminal determines the quantization information of the cache data based on the first configuration information; the quantization information of the cache data includes the quantization information of the cache data of at least one LCG and/or the quantization information of the delay of at least one LCG;

Step b: The terminal generates the BSR based on the quantization information of the cached data.

In this embodiment, the terminal quantifies the amount of cached data of at least one LCG based on the first information in the first configuration information to obtain cache data quantification information of at least one LCG; based on the second information in the first configuration information, the terminal quantifies the delay information of the cached data of at least one LCG to obtain delay quantification information of at least one LCG.

Then, the terminal generates a BSR based on the quantization information of the buffered data of at least one LCG and/or the delay information of the buffered data of at least one LCG.

Optionally, the first information includes at least one of the following:

a) first indication information, used to indicate a first data volume mapping relationship or a second data volume mapping relationship configured for at least one LCG;

b) second indication information, used to indicate a second data volume mapping relationship configured for a first LCG; the first LCG is any LCG among all LCGs;

Among them, the first data volume mapping relationship is used to indicate the correspondence between the data volume range and the index value; the second data volume mapping relationship is used to indicate the correspondence between the data volume range and the index value; the quantization accuracy of at least a part of the second data volume mapping relationship is higher than the quantization accuracy of the corresponding part of the first data volume mapping relationship.

Specifically, the quantization accuracy refers to the accuracy of the data amount indicated by the index value of the data amount range; a higher quantization accuracy means that the deviation between the data range indicated by the index value and the actual data amount is smaller.

The first data volume mapping relationship or the second data volume mapping relationship indicates index values corresponding to different data volume ranges; wherein the first data volume mapping relationship is, for example, a first data volume quantization table, which may include multiple data volume ranges, and index values corresponding to the data volume ranges; the data volume ranges correspond one-to-one to the index values.

The second data volume mapping relationship is, for example, a second data volume quantization table, which may include multiple data volume ranges and index values corresponding to the data volume ranges; the data volume ranges and the index values correspond one to one.

In actual applications, the buffer size level length (buffer size level length) corresponding to the second data volume mapping relationship is greater than the buffer size level length corresponding to the first data volume mapping relationship; and the first data volume mapping relationship and the second data volume mapping relationship respectively correspond to LCGs with different data volume size ranges.

Optionally, the second information includes at least one of the following:

a) a delay mapping relationship, where the delay mapping relationship is used to indicate a correspondence between a delay value range and an index value;

Specifically, the delay mapping relationship, such as a delay quantization table, is predefined by the protocol or configured by the network.

b) Time granularity.

Specifically, the base station configures a time granularity for the UE. The time granularity can be configured as X (X>=1) ms, 1/N ms, time slot (including reference carrier spacing (subcarrier spacing))/symbol, X is greater than or equal to 1, N is greater than or equal to 1.

In the above implementation, the terminal quantizes the cache data based on the first configuration information to obtain at least one LCG. The cache data quantification information and the delay quantification information of at least one LCG are quantified. By quantifying the cache data, the BSR generated based on the quantification information of the cache data can achieve a balance between the BSR reporting information and the position information, and can reduce the position information overhead.

The following describes quantifying the amount of cached data of at least one LCG and quantifying the delay information of cached data of at least one LCG.

1. Quantify the amount of cache data of at least one LCG

Since XR services include multiple types of service data, such as voice, uplink auxiliary information, and video data, and the UE may also have other services; however, not all service data requires a higher quantization accuracy. The base station can configure the quantization table of uplink data volume according to LCG.

For example, when the UE is configured with two LCGs (i.e., LCG1 and LCG2), LCG1 corresponds to a smaller amount of data and can be configured to use the first quantization table (i.e., the existing quantization table), while LCG2 corresponds to a higher amount of data and can be configured to use the second quantization table (i.e., the new quantization table), wherein the second quantization table has a higher data amount quantization accuracy.

Therefore, in a case where the first configuration information includes the first information, the terminal determines the quantization information of the cache data based on the first configuration information, which is specifically implemented by the following steps:

Step a, the terminal determines a data volume mapping relationship corresponding to at least one LCG based on the first information;

Step b: The terminal determines the cache data quantization information of at least one LCG based on the data volume mapping relationship corresponding to at least one LCG and the data volume of the cache data of at least one LCG.

In this embodiment, the terminal determines a data volume mapping relationship with different quantization precisions for at least one LCG based on the first indication information and the second indication information in the first information, and then determines the cache data quantization information of the LCG based on the data volume mapping relationship corresponding to the LCG and the data volume of the cached data of the LCG.

Through the above method, the cached data volume of at least one LCG is quantized by utilizing the data volume mapping relationship with different data volume quantization precisions, so that different precisions of quantization can be achieved according to the quantization precision requirements of at least one LCG, thereby adjusting the balance between reporting and position information, and further reducing the overhead of position information.

Optionally, the terminal determines, based on the first information, a data volume mapping relationship corresponding to at least one LCG, specifically by any of the following methods:

Method 1: When the first information includes the first indication information, the terminal obtains the first data volume mapping relationship or the second data volume mapping relationship configured for at least one LCG based on the first indication information.

In actual applications, the base station configures the first data volume quantization table or the second data volume quantization table for at least one LCG/LCH; in the same BSR MAC CE, the LCG/LCH configured to use the first data volume quantization table uses the existing buffer size level length (for example, 8 bits), and the LCG/LCH configured to use the second data volume quantization table uses the new buffer size level length (for example, >8 bits).

Mode 2: When the first information includes the second indication information, the terminal determines the second data volume mapping relationship as a data volume mapping relationship corresponding to at least one LCG.

In actual applications, when the base station configures the second data volume quantization table for any LCG/LCH among all LCG/LCHs, all LCG/LCHs use the second data volume quantization table for quantization and use a new buffer size level length (for example >8bit).

Method 3: When the first information includes the second indication information and the first LCG has data, the terminal determines the second data volume mapping relationship as a data volume mapping relationship corresponding to at least one LCG.

In actual applications, the base station configures a second data volume quantization table for any LCG/LCH among all LCG/LCHs, and when the LCG/LCH has data, all LCG/LCHs use the second data volume quantization table for quantization and use a new buffer size level length (for example >8bit).

Method 4: When the first information includes the second indication information and the first LCG has no data, the terminal determines the first data volume mapping relationship as the data volume mapping relationship corresponding to other LCGs in at least one LCG except the first LCG.

In actual applications, the base station configures a second data volume quantization table for any LCG/LCH among all LCG/LCHs, and when the LCG/LCH has no data, other LCG/LCHs in at least one LCG except the first LCG use the first data volume quantization table and the existing buffer size level length (i.e. 8 bits).

It can be understood that among the above methods 1 to 4, method 1 is the most position-saving, but is relatively complicated compared to other methods; method 2 is the easiest to implement, but has the largest position overhead; the position overhead of methods 3 and 4 is between method 1 and method 2.

In the above implementation, the terminal quantizes the cached data volume of at least one LCG using a data volume mapping relationship with different data volume quantization precisions, and can achieve quantization of different precisions according to the quantization precision requirements of at least one LCG, thereby adjusting the balance between reporting and position information, and further reducing the overhead of position information.

2. Quantify the latency information of cached data of at least one LCG

In the case where the first configuration information includes the second information, the terminal determines the quantization information of the cache data based on the second configuration information, specifically by at least one of the following methods and steps:

Method 1: When the first configuration information includes the second information and the second information includes the delay mapping relationship, the terminal determines the delay quantization information of at least one LCG based on the delay mapping relationship and the delay information of the cached data of at least one LCG.

In practical applications, when the terminal needs to report the delay or the remaining delay budget, the protocol can predefine a delay quantization table, or the base station can configure a delay quantization table for the terminal through Radio Resource Control (RRC) signaling. Each serial number in the table corresponds to a delay value or the remaining delay budget value; the terminal performs delay quantization according to the delay quantization table.

Method 2: When the first configuration information includes the second information and the second information includes the time granularity, the terminal determines the delay quantization information of at least one LCG based on the time granularity and the delay information of the cached data of at least one LCG.

In the above embodiment, when the first information includes the second information, the terminal determines the delay quantization information of each LCG based on the delay mapping relationship and the delay information of the cached data of at least one LCG; and/or the terminal determines the delay quantization information of each LCG based on the time granularity and the delay information of the cached data of at least one LCG; through the above method, quantization of different precisions is achieved for the quantization precision requirements of at least one LCG based on the delay mapping relationship and/or time granularity, thereby adjusting the balance between reporting and position information, thereby reducing the overhead of position information.

Alternatively, if the terminal reports the delay for each data packet/data burst/PDU set, it will also cause a large position overhead; in addition, if the remaining delay budget for the uplink data is still long, the delay information of the data will not be of much help to the base station scheduling.

Therefore, in order to reduce the overhead of the position information, in this embodiment, the terminal generates the BSR based on the quantified information of the first information, which can be specifically implemented in at least one of the following ways:

Method 1: When the first configuration information includes the second information, the terminal generates the BSR based on the second information and the delay information of the cached data of at least one LCG; the BSR includes third indication information corresponding to at least one LCG and the delay information of the cached data of at least one LCG; the third indication information is used to indicate whether the BSR includes the delay information of the cached data of the corresponding LCG.

Specifically, in the case where the first configuration information includes the second information, in order to save the position overhead of delay information reporting, the terminal may determine whether to include the delay information of the cache data of an LCG in the BSR according to a preset condition.

That is to say, the BSR generated by the terminal includes third indication information corresponding to at least one LCG, and the third indication information is used to indicate whether the BSR includes the delay information of the cache data of the corresponding LCG; when the delay information corresponding to an LCG has an indication position, it means that the delay information of the cache data of the LCG is included in the BSR.

Mode 2: When the first configuration information includes the second information, and the delay of the data of any logical channel LCH included in the second LCG is not less than the first threshold, and/or the remaining delay budget is less than the second threshold, the terminal generates the BSR based on the second information and the delay information of the cached data of the second LCG; the BSR includes Including fourth indication information associated with the second LCG, and delay information of cached data of the second LCG; the fourth indication information is used to indicate that the BSR includes delay information of cached data of the second LCG; wherein the second LCG is any LCG of the at least one LCG.

Specifically, when the first configuration information includes the second information, and the delay of the data of any LCH included in the second LCG is not lower than the first threshold, and/or the remaining delay budget is lower than the second threshold, the fourth indication information associated with the second LCG can be used in the BSR to indicate whether the delay information of the cached data of the second LCG is included.

When the delay information of the cached data of a second LCG has an indication bit set, it means that the delay information of the cached data of the second LCG is included in the BSR. The first threshold/second threshold is configured by the base station; if there are N LCGs, there are N indication bits, which are used to indicate whether there is a corresponding delay information/remaining delay budget information report for each second LCG.

Method 3: When the first configuration information includes the second information, and the delay of the data of any LCH included in the second LCG is not less than the first threshold, and/or the remaining delay budget is less than the second threshold, the terminal generates the BSR based on the second information and the delay information of the cached data of the second LCG; the BSR includes the fifth indication information associated with the second LCG; the fifth indication information is used to indicate that the delay of the data of any LCH included in the second LCG is not less than the first threshold, and/or the remaining delay budget is less than the second threshold; wherein the second LCG is any LCG among the at least one LCG.

Specifically, when the first configuration information includes the second information, and the delay of the data of any LCH included in the second LCG is not lower than the first threshold, and/or the remaining delay budget is lower than the second threshold, each LCG corresponds to a delay indication bit (fifth indication information). When the indication bit is set, it indicates that the delay of the data of any LCH included in the second LCG is not lower than the first threshold, and/or the remaining delay budget is lower than the second threshold.

It should be noted that the first threshold/second threshold is configured by the base station, and the terminal determines whether the indication bit is set according to whether the delay of LCH data in an LCG is not less than the first threshold and/or the remaining delay budget is less than the second threshold. In mode 3, the BSR may not carry the delay value corresponding to the cached data of each LCG.

Method 4: When the first configuration information includes the second information and the delay of data of any LCH included in the second LCG is not lower than the first threshold, and/or the remaining delay budget is lower than the second threshold, the terminal generates the BSR based on the second information and the delay information of the second LCG; the BSR includes the sixth indication information and the seventh indication information associated with the second LCG; the sixth indication information is used to indicate that the BSR includes the seventh indication information; the seventh indication information is used to indicate the data volume of the first data in the second LCG or the proportion of the data volume to the total data volume of the second LCG; the delay of the first data is not lower than the first threshold and/or the remaining delay budget is lower than the second threshold; wherein the second LCG is any LCG among the at least one LCG.
