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 described below.
The new BSR format enables the UE to report delay information of uplink data and reduce quantization errors of the amount of uplink data, wherein in the BRS reporting process, delay information quantization problems of data packets, quantization problems of uplink buffer data, and triggering problems of BSR based on delay information are involved. The new BSR may contain delay information for the uplink data and/or lower quantization errors, which also means a larger BSR size.
Regarding Rel-15/16BSR:
rel-15 BSR is currently supported by default, in Rel-15 BSR there are BSRs of the following types:
1. The Regular (Regular) BSR triggers in any case:
a) LCHs with higher priority than Logical Channels (LCHs) currently having data transmission change from no data transmission to having data transmission;
b) One LCH becomes data-sent when all LCHs do not have data to send;
c) At least one LCH has data to transmit when a BSR retransmission Timer (retxBSR-Timer) expires.
2. Periodicity BSR (Periodic BSR) is triggered when the periodic BSR transmit Timer (periodicBSR-Timer) expires.
3. Additional BSR (Padding BSR): when a media intervention Control layer (MEDIA ACCESS Control, MAC) protocol data unit (Protocol Data Unit, PDU) has a remaining capacity to accommodate BSR MAC Control elements (MAC Control Element, MAC CE) after accommodating all data.
One LCH belongs to one LCH group (LCG), and the buffer size class (buffer size level, BS) of the BSR is reported according to the LCG unit, and can be configured with 8 LCGs at most. The Regular BSR may trigger the transmission of an SR. If no grant is obtained after the last SR transmission, SR retransmission may be triggered.
The BSR MAC CE format of NR Rel-15 is shown in FIGS. 2 and 3. Fig. 2 is one of the format schematics of a BSR MAC CE in the prior art; the BSR MAC CE formats shown in fig. 2 are those of a short BSR and a short truncated BSR MAC CE; where Oct represents octal. FIG. 3 is a second diagram of a format of a BSR MAC CE according to the prior art; the formats of the BSR MAC CE shown in fig. 3 are the formats of a long BSR and a long truncated BSR MAC CE; where Oct represents octal.
For the regular/periodic BSR, if the UE has more than one LCG with data, a long BSR is used, otherwise a short BSR is used.
Concept of protocol data unit set (PDU set) for Extended Reality (XR)
XR is a video service provided based on low latency, high definition. The media data unit of the current video service is PDU set unit. One PDU set contains at least one PDU, which is generated by encoding one image or one image area by the video source end, and the video receiving end can decode the video after receiving the PDU belonging to one PDU set, and recover the corresponding image or image area.
In summary, in the process of reporting more detailed information to the base station by the UE using the new BSR format, the balance between reporting and position information needs to be considered.
The BSR reporting method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through some embodiments and application scenarios thereof. The embodiment of the application can be applied to the situation of higher-precision cache information reporting and/or time delay information reporting, and can be potentially applied to all business types including XR.
Fig. 4 is a flowchart of a BSR reporting method according to an embodiment of the present application, as shown in fig. 4, including step 401; wherein:
Step 401, the terminal generates a BSR of the cache data based on the first configuration information; the BSR comprises reporting information of at least one logic channel group LCG; the first configuration information includes at least one of: the first information is used for indicating data volume reporting configuration of cache data of at least one LCG; and second information, configured to instruct delay information reporting configuration of the buffered data of the at least one LCG.
It should be noted that the embodiment of the present application may be applied to a BSR reporting scenario; terminals include, but are not limited to, the types of terminals 11 listed above, as the application is not limited in this regard.
Since the UE needs to consider the balance of reporting and position information in the flow of reporting more detailed information to the base station using the new BSR format; in order to reduce the overhead of the location information, in this embodiment, the terminal needs to generate a BSR for caching data based on the first configuration information.
Optionally, before the terminal generates the BSR of the buffered data based on the first configuration information, the terminal needs to receive the first configuration information from the network side device.
Optionally, after the terminal generates the BSR to be transmitted, the terminal needs to send the BSR to the network side device.
In the BSR reporting method provided by the embodiment of the present application, the terminal generates the BSR of the buffered data based on the first configuration information, and because the first configuration information relates to the data volume reporting configuration and/or the time delay information reporting configuration, the terminal can balance the BSR reporting information and the position information based on the BSR generated by the data volume reporting configuration and/or the time delay information reporting configuration, and can reduce the position information overhead.
Optionally, the terminal generates the BSR of the buffered data based on the first configuration information, specifically including the following steps:
Step a, the terminal determines quantization information of the cache data based on the first configuration information; the quantization information of the cache data comprises cache data quantization information of at least one LCG and/or delay quantization information of at least one LCG;
and b, the terminal generates the BSR based on the quantization information of the cache data.
In this embodiment, the terminal quantizes the data amount of the buffered data of at least one LCG based on the first information in the first configuration information, to obtain buffered data quantization information of at least one LCG; and quantizing the time delay information of the cache data of the at least one LCG based on the second information in the first configuration information to obtain time delay quantized information of the at least one LCG.
And then the terminal generates a BSR based on the buffer data quantization information of at least one LCG and/or the delay information of the buffer data of at least one LCG.
Optionally, the first information includes at least one of:
a) The first indication information is used for indicating a first data volume mapping relation or a second data volume mapping relation configured for at least one LCG;
b) The second indication information is used for indicating a second data volume mapping relation configured for the first LCG; the first LCG is any one of all LCGs;
the first data volume mapping relation is used for indicating the corresponding relation between the data volume range and the index value; the second data volume mapping relation is used for indicating the corresponding relation between the data volume range and the index value; the quantization accuracy of at least a portion of the second data amount mapping relation is higher than the quantization accuracy of a corresponding portion of the first data amount mapping relation.
Specifically, the quantization accuracy represents the accuracy of the data amount indicated by the index value of the data amount range; higher quantization accuracy indicates that the data range indicated by the index value deviates less from the actual data amount.
The first data amount mapping relation or the second data amount mapping relation indicates index values corresponding to different data amount ranges; the first data amount mapping relationship is, for example, a first data amount quantization table, and may include a plurality of data amount ranges and index values corresponding to the data amount ranges; the data volume ranges are in one-to-one correspondence with the index values.
The second data amount mapping relationship is, for example, a second data amount quantization table, and may include a plurality of data amount ranges and index values corresponding to the data amount ranges; the data volume ranges are in one-to-one correspondence with the index values.
In practical application, 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 relation and the second data volume mapping relation respectively correspond to LCGs with different data volume size ranges.
Optionally, the second information includes at least one of:
a) The time delay mapping relation is used for indicating the corresponding relation between the time delay value range and the index value;
In particular, the delay mapping relationship, e.g. delay quantization table, is predefined by the protocol or configured by the network
B) Time granularity.
Specifically, the base station configures the UE with a time granularity, where the time granularity may be configured as X (X > =1) ms,1/N ms, a time slot (including the reference carrier interval (subcarrier spacing))/symbol, X is greater than or equal to 1, and N is greater than or equal to 1.
In the above embodiment, the terminal quantizes the buffered data based on the first configuration information to obtain buffered data quantization information of at least one LCG and delay quantization information of at least one LCG, and by quantizing the buffered data, the BSR generated based on the quantized information of the buffered data can balance BSR reporting information and position information, so that position information overhead can be reduced.
The quantization of the data amount of the buffered data of the at least one LCG and the quantization of the delay information of the buffered data of the at least one LCG are described below.
1. Quantifying data amount of cached data of at least one LCG
Since XR service contains multiple types of service data, such as voice, uplink auxiliary information, video data, other services are possible for the UE; however, not all traffic data need to use higher quantization accuracy. The base station may configure a quantization table for the amount of uplink data per LCG.
For example, when the UE is configured with two LCGs (i.e., LCG1 and LCG 2), LCG1 corresponds to a smaller data amount, a first quantization table (i.e., an existing quantization table) may be configured for use, and LCG2 corresponds to a higher data amount, and a second quantization table (i.e., a new quantization table) may be configured for use, wherein the second quantization table has a higher data amount quantization accuracy.
Therefore, in the case that the first configuration information includes the first information, the terminal determines quantization information of the buffered data based on the first configuration information, specifically by:
step a, the terminal determines a data quantity mapping relation corresponding to at least one LCG based on the first information;
and b, the terminal determines cache data quantization information of at least one LCG based on the data amount mapping relation corresponding to the at least one LCG and the data amount of the cache data of the at least one LCG.
In this embodiment, the terminal determines, for at least one LCG, a data amount mapping relationship with different quantization accuracy based on the first indication information and the second indication information in the first information, and then determines cache data quantization information of the LCG based on the data amount mapping relationship corresponding to the LCG and a data amount of cache data of the LCG.
By the method, the buffer data quantity of at least one LCG is quantized by utilizing the data quantity mapping relation with different data quantity quantization precision, so that the quantization with different precision aiming at the quantization precision requirement of at least one LCG can be realized, the balance of reporting and position information is adjusted, and the cost of the position information is further reduced.
Optionally, the terminal determines, based on the first information, a mapping relationship of data amounts corresponding to at least one LCG, specifically by any one of the following modes:
in mode 1, when the first information includes the first instruction information, the terminal obtains a first data amount mapping relation or a second data amount mapping relation configured for at least one LCG based on the first instruction information.
In practical application, a base station configures a first data quantity quantization table or a second data quantity quantization table for at least one LCG/LCH; in the same BSR MAC CE, LCG/LCH configured with the first data amount quantization table uses existing buffer size LEVEL LENGTH (e.g., 8 bits), LCG/LCH configured with the second data amount quantization table uses new buffer size LEVEL LENGTH (e.g., >8 bits).
Mode 2, where the first information includes the second indication information, the terminal determines the second data amount mapping relationship as a data amount mapping relationship corresponding to at least one LCG.
In practical applications, when the base station configures the second data amount quantization table for any one of all LCGs/LCHs, all LCGs/LCHs use the second data amount quantization table to quantize and use a new buffer size LEVEL LENGTH (e.g., >8 bits).
And 3, determining the second data quantity mapping relation as the data quantity mapping relation corresponding to at least one LCG by the terminal when the first information comprises the second indication information and the first LCG has data.
In practical applications, the base station configures a second data amount quantization table for any one of all LCGs/LCHs, and if the LCGs/LCHs have data, then all LCGs/LCHs use the second data amount quantization table for quantization and use a new buffer size LEVEL LENGTH (e.g., >8 bits).
And 4, determining the first data amount mapping relation as the data amount mapping relation corresponding to other LCGs except the first LCG in at least one LCG by the terminal under the condition that the first information comprises the second indication information and the first LCG has no data.
In practical applications, the base station configures a second data amount quantization table for any one LCG/LCH of all LCGs/LCHs, and if the LCG/LCH has no data, then the other LCGs/LCHs except the first LCG in at least one LCG use the first data amount quantization table and the existing buffer size LEVEL LENGTH (i.e. 8 bits).
It will be appreciated that, of modes 1 to 4, mode 1 is most economical in terms of position, but is more complicated than other modes; mode 2 is the easiest to implement, but the position overhead is the greatest; the position overhead of mode 3 and mode 4 is between mode 1 and mode 2.
In the above embodiment, the terminal quantizes the buffered data amount of at least one LCG by using the data amount mapping relationship with different data amount quantization precision, so as to implement quantization with different precision according to the quantization precision requirement of at least one LCG, thereby adjusting the balance of reporting and position information, and further reducing the overhead of position information.
2. Quantizing delay information of buffered data of at least one LCG
In the case that the first configuration information includes the second information, the terminal determines quantization information of the buffered data based on the second configuration information, specifically by at least one of the following steps:
In mode 1, when the first configuration information includes the second information and the second information includes the delay mapping relationship, the terminal determines delay quantization information of at least one LCG based on the delay mapping relationship and delay information of cache data of the at least one LCG.
In practical application, when the terminal needs to report delay or residual delay budget, the protocol may predefine a delay quantization table, or the base station configures a delay quantization table for the terminal through infinite resource control (Radio Resource Control, RRC) signaling, where each sequence number in the table corresponds to a delay value or residual delay budget value; and the terminal performs time delay quantization according to the time delay quantization table.
In mode 2, when the first configuration information includes the second information and the second information includes the time granularity, the terminal determines delay quantization information of at least one LCG based on the time granularity and delay information of cache data of the at least one LCG.
In the above embodiment, when the first information includes the second information, the terminal determines delay quantization information of each LCG based on the delay mapping relationship and delay information of the buffered data of at least one LCG; and/or the terminal determines delay quantization information of each LCG based on the time granularity and delay information of the cache data of at least one LCG; by the method, quantization with different precision aiming at the quantization precision requirement of at least one LCG is realized based on the time delay mapping relation and/or the time granularity, so that the balance of reporting and position information is adjusted, and the cost of the position information is further reduced.
Optionally, if the terminal reports delay for each data packet/data burst/PDU set, the situation of large position overhead is also caused; in addition, if the residual delay budget of the uplink data is longer, the delay information of the data is not helpful to the base station scheduling.
Therefore, in order to reduce the overhead of the location information, in this embodiment, the terminal generates the BSR based on the quantized information of the first information, which may be specifically implemented by at least one of the following ways:
In mode 1, when the first configuration information includes the second information, the terminal generates the BSR based on the second information and delay information of cache data of at least one LCG; the BSR comprises third indication information corresponding to at least one LCG and time delay information of cache data of at least one LCG; the third indication information is used for indicating whether the BSR includes delay information of the corresponding cache data of the LCG.
Specifically, in the case that the first configuration information includes the second information, in order to save the position overhead of the delay information report, the terminal may determine whether to include the delay information of the buffered data of one LCG in the BSR according to a preset condition.
That is, the BSR generated by the terminal includes third indication information corresponding to at least one LCG, where the third indication information is used to indicate whether the BSR includes delay information of buffered data of the corresponding LCG; when the indication position bit exists in the delay information corresponding to one LCG, the delay information of the cache data representing the LCG is contained in the BSR.
Mode 2, when the first configuration information includes the second information and the time delay of the data of any logic channel LCH included in the second LCG is not lower than a first threshold and/or the residual time delay budget is lower than a second threshold, the terminal generates the BSR based on the second information and the time delay information of the buffered data of the second LCG; the BSR comprises fourth indication information associated with the second LCG and time delay information of cache data of the second LCG; the fourth indication information is used for indicating time delay information of the buffer data of the second LCG included in the BSR; wherein the second LCG is any one 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 residual delay budget is lower than the second threshold, the delay information of the buffered data of the second LCG may be indicated in the BSR according to fourth indication information associated with the second LCG.
