The reported data amount in the BSR is the sum of all data amounts in the LCG after the logical channel priority procedure (Logical Channel Priority, LCP) is performed after the MAC PDU is generated.
The amount of data reported in the DSR is different from the amount of data in the BSR, and the amount of data reported in the DSR is less than the threshold value of the network configuration since the remaining time for packet discard is less than the threshold value of the network configuration. Furthermore, even if the amount of data reported in the DSR is large, the likelihood that network device 102 can schedule a large amount of data before the terminal 101 performs packet dropping is low, given that the network has not previously been able to provide sufficient resources to schedule the terminal 101 to transmit the portion of data. Reporting a large amount of data in the DSR does not greatly aid network scheduling.
Based on the different ranges of the data amounts reported by the DSR and the BSR, if the reporting mode of the BSR (such as a BSR table) is adopted to report the data amount of the DSR, the data amount may be inaccurate, which causes resource waste during network scheduling.
Figure 2a is an interactive schematic diagram illustrating a method of transmitting and receiving DSR in accordance with an embodiment of the present disclosure. As shown in fig. 2a, an embodiment of the present disclosure relates to a method of transmitting and receiving DSR, the method comprising:
in step S2101, the network apparatus 102 transmits configuration information to the terminal 101.
In some embodiments, configuration information may be used to configure a mapping relationship of an index (index) to an amount of DSR data, such as configuring a mapping table applicable to DSR data.
Optionally, the DSR data volume comprises: and the data quantity corresponding to the data packet with the remaining time of discarding the distance packet smaller than the threshold value.
Alternatively, the data packet may include a data packet of the PDCP layer, a data packet of the MAC layer, or the like.
In some embodiments, configuration information may be used to configure relevant parameters that generate a mapping relationship or DSR data volume.
Optionally, the configuration information includes at least one of:
minimum value of data quantity B min
Maximum value of data quantity B max
A first algorithm.
Alternatively, the amount of data may range from a minimum value B min To maximum value B max Between them.
Alternatively, the first algorithm may be an exponential algorithm or a linear algorithm.
In an example, network device 102 may configure B min 、B max And a first algorithm, wherein the terminal 101 generates DSR data volume and mapping relation according to the configuration of the network device 102.
In another example, network device 102 may configure B min B (B) max And the first algorithm is defined by the protocol, and the terminal 101 generates DSR data volume and mapping relation according to the configuration of the network device and the protocol definition.
In some embodiments, the configuration information is sent through RRC signaling or medium access control units (Media Access Control Control Element, MAC CEs).
Optionally, the network device 102 sends configuration information to the terminal 101 through RRC signaling, as may be configured in the MAC entity, i.e. the configuration information is contained in the IE MAC-CellGroupConfig.
Optionally, the granularity of the configuration information is LCG. For example, when configured in a MAC entity, the configuration information may include a mapping relationship for each LCG in the MAC entity, such as an index or DSR data volume corresponding to each LCG.
In some embodiments, the terminal 101 receives the configuration information.
In some embodiments, step S2101 may be omitted.
Alternatively, the mapping relationship is defined by a protocol, such as defining a mapping table applicable to DSR data, in which case step S2101 may be omitted.
In step S2102, terminal 101 transmits DSR to network device 102.
In some embodiments, an index is included in the DSR, the index having a mapping relationship with an amount of DSR data, the amount of DSR data comprising: the amount of data (data volume) corresponding to the data packet having a remaining time from packet discard less than the threshold.
Optionally, the remaining time is determined from a packet discard timer configured by the network device 102.
For example, network device 102 may configure a corresponding packet discard timer for the data packet, which may be discarded when the timer expires (e.g., the remaining time is 0).
Optionally, the threshold is configured for the network device 102.
For example, network device 102 may configure terminal 101 with a threshold (remaining time threshold) via RRC signaling, which is a threshold for UL data remaining time configured by LCG triggering DSR.
Optionally, the MAC entity triggers DSR when the remaining time of the PDU in the LCG is less than its associated remaining time threshold.
In some embodiments, DSR is used to provide a delay status of UL data to network device 102. For example, DSR includes: the remaining time corresponding to the data packet, and the amount of data associated with the reported remaining time. Wherein the data amount may be indicated by means of an index. The remaining time is based on the value of the packet discard timer associated with the amount of data at the first symbol of the PUSCH transmission used to transmit DSR.
In some embodiments, the DSR includes a first information field for indicating the remaining time and a second information field for indicating an index corresponding to the amount of data.
Alternatively, taking the example of terminal 101 transmitting a DSR through a MAC CE, signaling of the DSR MAC CE may be as shown with reference to fig. 2 b. The DSR MAC CE includes a first information field, which may be a time remaining information field (Delay Info), for indicating a time remaining; the second information field may be a Data Volume (Data Volume) field for indicating an index corresponding to the DSR Data Volume.
Alternatively, the first information field may be 4 bits (bits) in length and the second information field may be 8 bits in length.
Optionally, the DSR MAC CE may also include an LCG i And the domain is used for indicating whether the DSR MAC CE has the residual time information and the data volume information corresponding to the logical channel group i. For example, when LCG i When the domain value is 1, indicating that the residual time information and the data quantity information corresponding to the logical channel group i are reported; when LCG i And when the domain value is 0, indicating that the residual time information and the data quantity information corresponding to the logical channel group i are not reported.
Optionally, the index or the data amount reported in the second information field is determined according to a mapping relation of an embodiment of the disclosure.
In some embodiments, when the network device 102 determines a mapping relationship, or the protocol determines a mapping relationship, or the terminal 101 determines a mapping relationship according to a configuration and/or protocol definition of the network device 102, the determination may be based on a certain sequence generation algorithm.
In some embodiments, the DSR data amount in the mapping relationship is based on a minimum value B of the data amount min Maximum value B of data quantity max The number N of data quantity between the minimum value and the maximum value and the first algorithm.
Optionally, the first algorithm comprises an exponential algorithm or a linear algorithm.
Optionally, the number N is determined based on the number of bits in the DSR that are used to indicate the amount of data.
Wherein N is used for indicating the maximum index value in the mapping relation, and can also indicate the index value of the slave B min To B max The number of values of the data amount of (a). Assuming that the number of bits is x, n=2 x -1. For example, if the number of bits used to indicate the amount of data in DSR is 5 bits (bit), thenN is 31; for another example, if the number of bits used to indicate the amount of data in DSR is 8 bits, N is 255.
Wherein in the mapping relationship, index 0 can be used to indicate data amount 0, and maximum index value such as 31 or 255 can be used to indicate data amount>B max
Alternatively, the minimum value B min Greater than 0, or minimum value B min Less than or equal to the first value.
Wherein the amount of data reported in DSR is the amount of data that is less than the threshold of the network configuration from the time the packet is dropped, so no indication of data amount 0 is needed.
Wherein the first value may be a network device configuration or protocol defined value. Referring to the example of table 1, when a 5bit indicates the amount of data, the first value may be configured or defined as 100.
Optionally, the first algorithm is an exponential algorithm, and the DSR data volume is generated according to the following manner:
wherein p= (B) max /B min ) 1/(N-1) -1,B k Indicating the amount of data corresponding to the index k,representing a rounding up operation.

In some embodiments, the reported index in the DSR has a mapping relationship with the DSR data volume. The DSR data volume includes: and the data quantity corresponding to the data packet with the remaining time of discarding the distance packet smaller than the threshold value.
Optionally, the remaining time is determined according to a packet discard timer configured by the network device.

In some embodiments, the DSR includes a first information field for indicating the time remaining and a second information field for indicating an index corresponding to the amount of DSR data.
In some embodiments, reference may be made to other alternative implementations described before or after the description corresponding to fig. 4 c.
In the method of the disclosed embodiments, the amount of data reported in the DSR is the amount of data that is less than the threshold of the network configuration from the time the packet is dropped. The range of the data volume (e.g. B min And B is connected with max In particular B max ) As opposed to the range of data amounts reported in the BSR. First, the amount of data reported in the BSR is the sum of all the amounts of data in the LCG after the LCP procedure is performed, and the amount of data reported in the DSR is the amount of data that is less than the threshold of the network configuration from the time the packet is discarded. The amount of data reported in the DSR will typically be less than the amount of data reported in the BSR. Second, the amount of data reported in the DSR is the amount of data that is less than the threshold of the network configuration from the time the packet is dropped. Even if the data volume is large, the previous network is consideredThe network is not able to provide enough resources to schedule the UE to transmit data, and the likelihood that the network can schedule a large amount of data before the UE performs packet dropping is low. Reporting a large amount of data in the DSR does not greatly aid network scheduling. Therefore, the range of the data volume reported by the DSR is different from that of the data volume reported by the BSR, and the data volume reported by the DSR by adopting the BSR table is not accurate enough, so that the resource waste is caused during the network scheduling.
The method of the embodiment of the disclosure provides that when reporting the data volume in the DSR, the relation mapping between the reported index and the corresponding data volume is optimized for the DSR, and a Buffer status (Buffer Size) mapping table of the BSR (comprising a BSR table before Rel-18 and a BSR table to be introduced by Rel-18) is not adopted. The network scheduling efficiency and thus network capacity will be improved by a mapping table optimized for the amount of data reported by the DSR.
To facilitate an understanding of the disclosed embodiments, the following list of examples:
example one:
the relationship between the index and the corresponding data amount reported by the DSR may be a table defined in the protocol, or may be a relationship between the index and the corresponding data amount configured through a network.
Alternatively, the relationship of the index and the corresponding data amount corresponds to the mapping relationship of the foregoing embodiment.
Example two:
whether protocol-defined or network-configured, the relationship of the index to the corresponding amount of data is typically generated by a particular algorithm. The required parameters may include:
algorithm for generating a sequence of index-corresponding data amount: such as a linear formula or an exponential formula;
B min : a minimum value of the data amount;
B max : a maximum value of the data amount;
n: from B min To B max The number of values of the data amount of (a).
Alternatively, the value of N depends primarily on indicating the amount of data in the DSR with several bits. At the position ofThe data amount is indicated by 0 in the NR existing BSR table, and is indicated by 31 in the maximum index value (corresponding to 5bit Buffer Status and 255 in the maximum index value corresponding to 8bit Buffer Status)>B max
Alternatively, the data volume indication reported in the DSR may be similar to the BSR, or some optimization may be done. For example, the amount of data reported in DSR is the amount of data that is less than the threshold of the network configuration from the time the packet is dropped, so no indication of data amount 0 is needed. Thus for x bit index values, slave B min To B max Number of values of data amount n=2 x -1. For example, for 5bit and 8bit index values, N is 31 and 255, respectively.
When the array generation algorithm is exponential, the DSR data volume is generated using the following formula:
when the array generation algorithm is linear, the DSR data volume is generated using the following formula:
taking a 5bit index value as an example, when adopting an exponential mode, B min =100Bytes、B max When =100000 Bytes, and n=31, the relationship between the index and the corresponding data amount is shown in table 1.
Example three:
the relationship between the index and the corresponding data amount is configured through the network, and may be configured through RRC signaling or may be configured through MAC CE. When configured with RRC signaling, it may be configured in the MAC entity (i.e., in the IE MAC-CellGroupConfig) or may be configured with LCG as granularity.
Example four:
the network may configure one or more parameters generated by a relational algorithm that indexes the corresponding amount of data.
For example, the network may configure an algorithm (linear or exponential), B, that indexes the generation of a sequence of corresponding data amounts min 、B max Etc., while the remaining parameters are specified by standards. For example, the standard may specify that the generation algorithm is an exponential algorithm, N is 31 and 255 for 5bit and 8bit index values, respectively, and B is configured by signaling min And B max
Example five:
