Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, and in particular to an information processing method and device and a readable storage medium. BACKGROUND

[0002] The existing system introduces an XR (Extended Reality) service. In view of the strict delay requirement of the XR service, if a base station can accurately grasp the residual delay of terminal buffered data, the base station can perform delay-sensitive scheduling based on the residual delay, so as to better meet the delay requirement of the terminal service. Therefore, a delay status report (DSR) is introduced.

[0003] In the prior art, a terminal reports delay-sensitive data in a DSR, and a network device allocates uplink resources according to the DSR. If the terminal has data with a higher priority than the delay-sensitive data at this time, the data with the higher priority will preempt the uplink resources allocated by the network device, so that the delay-sensitive data cannot be transmitted, and the delay requirement of the delay-sensitive data cannot be met.

[0203] Referring to Figure 1 , Figure 1 Fig. 1 is a flowchart of an information processing method provided in an embodiment of the present application, which is applied to a terminal, as shown in Fig. 2, comprising the following steps: Figure 1

[0204] Step 101, in a case where it is determined that a DSR is triggered, sending first information to a network device.

[0205] The first information is used to indicate the data amount of target data in the terminal buffer, and the priority of the target data is higher than the priority of part or all delay-critical data.

[0206] The target data can also be referred to as high-priority data. The data amount of the target data can be the total data amount of the target data. In the embodiments of the present application, the target data can be determined by one or more of the following ways:

[0207] ​(1) taking first data as the target data, the first data including available data of all logical channels whose logical channel priorities are higher than that of the first logical channel of the terminal.

[0208] (2) taking second data as the target data, the second data including available data of all logical channels whose logical channel priorities are higher than that of the second logical channel within the first logical channel group of the terminal.

[0209] (3) taking third data as the target data, the third data including data of each logical channel whose logical channel priority is higher than that of the first logical channel of the terminal.

[0210] The first logical channel and / or the second logical channel include a logical channel triggering DSR or a logical channel having delay-sensitive data to be reported.

[0211] Specifically, the first logical channel includes one or more of the following:

[0212] a logical channel with the lowest logical channel priority among all logical channels triggering DSR;

[0213] a logical channel with the lowest logical channel priority among all logical channels having delay-sensitive data to be reported.

[0214] Specifically, the second logical channel includes one or more of the following:

[0215] a logical channel with the lowest logical channel priority among all logical channels belonging to the first logical channel group and triggering DSR;

[0216] a logical channel with the lowest logical channel priority among all logical channels belonging to the first logical channel group and having delay-sensitive data to be reported;

[0217] a logical channel with the lowest logical channel priority among all logical channels triggering DSR;

[0218] a logical channel with the lowest logical channel priority among all logical channels having delay-sensitive data to be reported.

[0219] Specifically, the first logical channel group includes one or more of the following:

[0220] a logical channel group to which a logical channel triggering DSR belongs;

[0221] a logical channel group to which a logical channel having delay-sensitive data to be reported belongs;

[0222] a logical channel group triggering DSR;

[0223] a second logical channel group, no logical channel in the second logical channel group triggers DSR, and a logical channel priority of at least one logical channel having available data in the second logical channel group is higher than a logical channel priority of a logical channel triggering DSR;

[0224] a second logical channel group, no logical channel in the second logical channel group triggers DSR, and a logical channel priority of at least one logical channel having available data in the second logical channel group is higher than a logical channel priority of a logical channel triggering DSR;

In the case of sending the first information to the network device through the first MAC CE, if DSR is triggered, the first information is sent to the network device through the first MAC CE.

[0232] That is, in the embodiments of the present application, the first information can be reported to the network device through a first DSR MAC CE, or reported using a separate MAC CE (hereinafter referred to as a first MAC CE). The first DSR MAC CE includes a MAC CE for reporting DSR.

[0233] If the first information is sent to the network device through the first DSR MAC CE, the first DSR MAC CE comprises: a first field, used for indicating the first information. Optionally, the first DSR MAC CE further comprises one or more of the following:

[0234] a third field, used for indicating a BS table corresponding to the data amount of the target data;

[0235] a fourth field, used for indicating whether the DSR MAC CE comprises the first field.

[0236] If the first information is sent to the network device through the first MAC CE, the first MAC CE and the second DSR MAC CE are sent to the network device simultaneously, or the first MAC CE and the second DSR MAC CE are sent to the network device by using adjacent uplink resources (uplink time / frequency resources) respectively; wherein the second DSR MAC CE is used for reporting a DSR.

[0237] wherein the first MAC CE comprises: a second field, used for indicating the first information.

[0238] Optionally, the first MAC CE further comprises: a fifth field, used for indicating a BS table corresponding to the data amount of the target data.

[0239] In this case, the priority of the first MAC CE is higher than the priority of the second DSR MAC CE; or the priority of the first MAC CE is lower than the priority of the second DSR MAC CE, and the priority of the first MAC CE is higher than the priority of an SL-BSR and / or the priority of a BSR MAC CE except for a padding BSR; or the priority of the first MAC CE is lower than the priority of an SL-BSR and / or the priority of a BSR MAC CE except for a padding BSR.

[0240] Optionally, in the embodiments of the present application, the sending of the first MAC CE can also be cancelled. For example, when the following cancellation conditions are met, the sending of the first information to the network device through the first MAC CE is cancelled, and the cancellation conditions comprise one or more of the following:

[0241] a BSR is triggered in a time period from the triggering of the DSR to the sending of the DSR MAC CE;

[0242] an uplink grant can carry all target data;

[0243] the DSR is cancelled;

[0244] MAC reset;

[0245] All latency sensitive data is discarded;

[0246] Uplink grant can carry all latency sensitive data;

[0247] Uplink grant can carry all available data of the terminal.

[0248] Optionally, if the first MAC CE and / or the DSR MAC CE contains the data amount of all available data of the terminal, the SR and / or BSR triggered by the terminal can also be cancelled.

[0249] In the embodiments of the present application, the terminal can send first information to the network device, indicating the data amount of target data in the terminal buffer, the priority of the target data being higher than the priority of part or all latency sensitive data, so that the network device can allocate sufficient resources to carry the latency sensitive data, ensuring the transmission latency of the latency sensitive data.

[0250] Referring to Figure 2 , Figure 2 is a flowchart of an information processing method provided by the embodiments of the present application, applied to a network device, as shown in Figure 2 , comprising the following steps:

[0251] Step 201, receiving first information sent by a terminal, wherein the first information is sent in the case of determining to trigger DSR, and the first information is used to indicate the data amount of target data in the terminal buffer, the priority of the target data being higher than the priority of part or all latency sensitive data.

[0252] In this step, the network device can receive the first information sent by the terminal through the first DSR MAC CE; or receive the first information sent by the terminal through the first MAC CE.

[0253] If the network device receives the first information sent by the terminal through the first MAC CE, the first MAC CE and the second DSR MAC CE are sent simultaneously, or the first MAC CE and the second DSR MAC CE are sent by using adjacent uplink resources (uplink time / frequency resources) respectively; wherein the second DSR MAC CE is used to report DSR.

[0254] The priority of the first MAC CE is higher than the priority of the second DSR MAC CE, or the priority of the first MAC CE is lower than the priority of the second DSR MAC CE, and the priority of the first MAC CE is higher than the priority of an SL-BSR and / or the priority of a BSR MAC CE except for a padding BSR, or the priority of the first MAC CE is lower than the priority of an SL-BSR and / or the priority of a BSR MAC CE except for a padding BSR.

[0255] The format of the first DSR MAC CE or the first MAC CE can refer to the description in the foregoing embodiments.

[0256] In step 202, uplink resources are allocated according to the first information.

[0257] In this step, the network device allocates uplink resources according to the data amount of the target data indicated by the first information and the data amount of the buffer indicated in the DSR, so that sufficient uplink resources can be allocated according to the sum of the data amount of the target data indicated by the first information and the data amount of the buffer indicated in the DSR, to ensure that the target data and the data indicated in the DSR can both be allocated to resources.

[0258] In the embodiments of the present application, the terminal can send the first information to the network device, to indicate the data amount of target data in the buffer of the terminal, the priority of the target data being higher than the priority of part or all of the delay-sensitive data, so that the network device can allocate sufficient resources to carry the delay-sensitive data, to ensure the transmission delay of the delay-sensitive data.

[0259] In the following, the specific implementation process of the embodiments of the present application is described in detail in combination with different embodiments.

[0260] Referring to Figure 3 , Figure 3 is a flowchart of an information processing method provided by the embodiments of the present application. In the embodiments, the data amount of high-priority data is determined and reported by a terminal. The process can include the following steps.

[0261] In step 301, a DSR triggering condition is determined.

[0262] Specifically, whether the DSR is triggered can be determined based on a logical channel group (LCG) or based on a logical channel (LCH).

[0263] If based on the LCG, the DSR triggering condition is as follows:

[0264] If the remaining time of the PDCP discardTimer corresponding to all SDUs in one LCG is the smallest and is less than the threshold, and the SDU corresponding to the PDCP discardTimer is not included in the DSR MAC CE, and the current LCG has no pending DSR, the DSR is triggered for the LCG.

[0265] If based on LCH, the DSR triggering condition is as follows:

[0266] If the remaining time of the PDCP discardTimer corresponding to all SDUs in one LCG is the smallest and is less than the threshold, and the SDU corresponding to the PDCP discardTimer is not included in the DSR MAC CE, and the current LCG has no pending DSR, the DSR is triggered for the LCG.

[0267] Step 302, determine the data volume of delay-critical data in each LCG.

[0268] Before generating the DSR MAC CE, the terminal first needs to determine the data volume of the buffer corresponding to each LCG of the DSR to be reported. The data volume is the delay-critical UL data volume in the LCG.

[0269] Specifically, the Delay-critical UL data includes PDCP layer delay-critical PDCP data volume and radio link control (RLC) delay-critical RLC data volume.

[0270] Wherein:

[0271] The PDCP layer delay-critical PDCP data volume includes:

[0272] The delay-critical PDCP SDU for which the PDCP data PDU has not been generated;

[0273] PDCP data PDU containing delay-critical PDCP SDU and not submitted to lower layer;

[0274] PDCP Control PDU (PDCP Control PDU);

[0275] PDCP SDU to be retransmitted for AM Data Radio Bearer (DRB);

[0276] PDCP Data PDU to be retransmitted for AM DRB.

[0277] RLC layer delay-critical RLC data volume includes:

[0278] Delay-critical RLC SDU and delay-critical RLC SDU segments that have not yet generated RLC PDU;

[0279] RLC data PDU containing delay-critical RLC SDU or delay-critical RLC SDU segment waiting for initial transmission;

[0280] RLC data PDU waiting for retransmission for RLC Acknowledged Mode (AM).

[0281] In the above description, the definitions of delay-critical PDCP SDU and delay-critical RLC SDU are as follows:

[0282] Delay-critical PDCP SDU: If the PDU Set-based discard mechanism is not configured (i.e., the parameter pdu-SetDiscard is not configured), the PDCP SDU whose discardTimer remaining time is less than the threshold is a Delay-critical PDCP SDU. If the PDU Set-based discard mechanism is configured (i.e., the parameter pdu-SetDiscard is configured), if at least one PDCP SDU in the PDU Set has a discardTimer remaining time less than the threshold, all SDUs in the entire PDU Set are considered as Delay-critical PDCP SDU.

[0283] Delay-critical RLC SDU: If a PDCP PDU is indicated as delay-critical by PDCP, the RLC SDU related to this PDCP PDU is considered as Delay-critical RLC SDU.

[0284] In the above description, the definitions of delay-critical PDCP SDU and delay-critical RLC SDU are as follows, respectively:

[0285] Delay-critical PDCP SDU: If no PDU Set based discard mechanism is configured (i.e. parameter pdu-SetDiscard is not configured), the PDCP SDU whose discardTimer remaining time is less than the threshold is considered as Delay-critical PDCP SDU. If PDU Set based discard mechanism is configured (i.e. parameter pdu-SetDiscard is configured), if at least one PDCP SDU within a PDU Set has discardTimer remaining time less than the threshold, all SDUs within this PDU Set are considered as Delay-critical PDCP SDU.

[0286] Delay-critical RLC SDU: If a PDCP PDU is indicated as delay-critical by PDCP, the RLC SDU related to this PDCP PDU is considered as Delay-critical RLC SDU.

[0287] Step 303, determining the data volume of high priority data to be reported by the terminal.

[0288] Once the terminal has a DSR trigger, the terminal needs to report the data volume of high priority data (i.e. target data) in the terminal buffer to the network device. The determination method of the "high priority data" can be:

[0289] Based on the terminal determination, i.e. all available data of logical channels with priority higher than the first logical channel priority of the terminal.

[0290] The "available data" here can only include non-delay-sensitive data (such as non-Delay-critical UL data), or simultaneously include delay-sensitive data (such as Delay-critical UL data) and non-Delay-critical UL data.

[0291] The "first logical channel" specifically includes at least one of the following:

[0292] the logical channel with the lowest priority among all logical channels triggering DSR in the terminal;

[0293] the logical channel with the lowest priority among all logical channels having Delay-critical UL data to be reported in the terminal.

[0294] Step 304: The terminal reports the amount of Delay-critical UL data and the amount of high-priority data.

[0295] Specifically, there are two ways for the terminal to report the amount of Delay-critical UL data and the amount of high-priority data, which are as follows:

[0296] Method A: The amount of high-priority data is piggybacked to the network device through DSR MAC CE.

[0297] Method B: A separate MAC CE (referred to as first MAC CE) is used for the reporting of the amount of high-priority data, and the DSR MAC CE and the first MAC CE can be reported to the network device at the same time or reported to the network device separately by using adjacent uplink time-frequency resources.

[0298] For method A, specifically, the terminal can piggyback the amount of high-priority data to the network device through DSR MAC CE, and a field is added in the existing DSR MAC CE format to indicate the amount of high-priority data (i.e., the first field). Optionally, a field can also be added to indicate the BS table corresponding to the amount of high-priority data (i.e., the third field). Optionally, if the same BStable is used for the reporting of high-priority data and DSR for the same logical channel group, the BS table indication field corresponding to the high-priority data can be omitted. In order to distinguish the new DSR MAC CE from the existing DSR MAC CE, a new logical channel identification (LCID) can be introduced for the new DSR MAC CE. In addition, optionally, the Rbit before the Remaining Time field (i.e., the fourth field) can be used to indicate whether there is a field after the Remaining time to indicate the amount of high-priority data. The schematic diagram of the new DSR MAC CE can be as shown in Figure 4

[0299] ​For the way B, the first MAC CE needs to contain a field (i.e. the second field) to indicate the data volume of the high priority data. Optionally, a field (i.e. the fifth field) can be added to indicate the BStable corresponding to the data volume of the high priority data. An LCID can be introduced for the first MAC CE to identify the first MAC CE. The schematic diagram of the first MAC CE is shown in FIG. 6. Figure 5

[0300] In addition, for the way B, the first MAC CE is triggered when the DSR is triggered.

[0301] When the terminal receives the UL resource allocation (i.e. UL scheduling grant, also referred to as UL grant), the terminal needs to perform the logical channel prioritization (LCP). The priority of the first MAC CE can be any one of the following:

[0302] The priority of the first MAC CE is higher than the DSR MAC CE;

[0303] The priority of the first MAC CE is lower than the DSR MAC CE, but higher than the SL-BSR and / or other BSR MAC CEs except the padding BSR;

[0304] The priority of the first MAC CE is lower than the SL-BSR and / or other BSR MAC CEs except the padding BSR.

[0305] In addition, the cancellation conditions of the first MAC CE include any one of the following:

[0306] The BSR is triggered within the time period from the triggering of the DSR to the sending of the DSR MAC CE;

[0307] The uplink grant can carry all the target data;

[0308] The DSR is cancelled;

[0309] MAC reset;

[0310] All the delay-sensitive data is discarded;

[0311] The uplink grant can carry all the delay-sensitive data;

[0312] The uplink grant can carry all the available data of the terminal.

[0313] In addition, if the first MAC CE and / or the DSR MAC CE contains all the available data volume of the terminal, the SR and / or BSR triggered by the terminal is cancelled.​

[0314] Referring to Figure 6 , Figure 6 is a flowchart of the information processing method provided by the embodiment of the present application. In this embodiment, the data volume of high-priority data is determined and reported based on logical channel groups. The process can include:

[0315] Step 601, DSR triggering judgment.

[0316] Specifically, whether the DSR is triggered can be judged based on LCG or based on LCH.

[0317] If based on LCG, the DSR triggering condition is as follows:

[0318] The remaining time of the PDCP discardTimer corresponding to the minimum remaining time of the PDCP discardTimer of all SDUs in one LCG is less than the threshold, and the SDU corresponding to the PDCP discardTimer is not included in the DSR MAC CE, and the current LCG does not have a pending DSR, then the DSR is triggered for the LCG.

[0319] If based on LCH, the DSR triggering condition is as follows:

[0320] The remaining time of the PDCP discardTimer corresponding to the minimum remaining time of the PDCP discardTimer of all SDUs in one LCH is less than the threshold, and the SDU corresponding to the PDCP discardTimer is not included in the DSR MAC CE, and the current LCH does not have a pending DSR, then the DSR is triggered for the LCH.

[0321] Step 602, determining the data volume of delay-critical data in each LCG.

[0322] Before generating the DSR MAC CE, the terminal first needs to determine the data volume of the buffer corresponding to each LCG of the DSR to be reported. The data volume is the delay-critical UL data volume in the LCG.

[0323] Specifically, the delay-critical UL data includes PDCP layer delay-critical PDCP data volume and delay-critical RLC data volume.

[0324] Wherein:

[0325] The delay-critical PDCP data volume in the PDCP layer includes:

[0326] delay-critical PDCP SDUs that have not yet generated PDCP data PDUs;

[0327] PDCP data PDUs containing delay-critical PDCP SDUs and not submitted to lower layers;

[0328] PDCP Control PDUs;

[0329] for AM DRBs, PDCP SDUs to be retransmitted;

[0330] for AM DRBs, PDCP Data PDUs to be retransmitted.

[0331] The delay-critical RLC data volume in the RLC layer includes:

[0332] delay-critical RLC SDUs and delay-critical RLC SDU segments that have not yet generated RLC PDUs;

[0333] RLC data PDUs containing delay-critical RLC SDUs or delay-critical RLC SDU segments waiting for initial transmission;

[0334] for RLC AM, RLC data PDUs waiting for retransmission.

[0335] In the above description, the definitions of delay-critical PDCP SDUs and delay-critical RLC SDUs are as follows, respectively:

[0336] Delay-critical PDCP SDU: If the PDU Set-based discard mechanism is not configured (i.e., the parameter pdu-SetDiscard is not configured), the PDCP SDU whose discardTimer remaining time is less than the threshold is a Delay-critical PDCP SDU. If the PDU Set-based discard mechanism is configured (i.e., the parameter pdu-SetDiscard is configured), if at least one PDCP SDU in the PDU Set has a discardTimer remaining time less than the threshold, all SDUs in the PDU Set are considered Delay-critical PDCP SDUs.

[0337] Delay-critical RLC SDU: If a PDCP PDU is indicated as delay-critical by PDCP, the RLC SDU related to this PDCP PDU is considered as Delay-critical RLC SDU.

[0338] In the above description, the definitions of delay-Critical PDCP SDU and delay-critical RLC SDU are as follows, respectively:

[0339] Delay-critical PDCP SDU: If no PDU Set based discard mechanism is configured (i.e. parameter pdu-SetDiscard is not configured), the PDCP SDU whose discardTimer remaining time is less than the threshold is considered as Delay-critical PDCP SDU. If PDU Set based discard mechanism is configured (i.e. parameter pdu-SetDiscard is configured), if at least one PDCP SDU within a PDU Set has discardTimer whose remaining time is less than the threshold, all SDUs within this PDU Set are considered as Delay-critical PDCP SDU.

[0340] Delay-critical RLC SDU: If a PDCP PDU is indicated as delay-critical by PDCP, the RLC SDU related to this PDCP PDU is considered as Delay-critical RLC SDU.

[0341] Step 603, determine the data volume of high priority data to be reported by the terminal.

[0342] Once the terminal has a DSR trigger, the terminal needs to report the data volume of high priority data (i.e. target data) in the terminal buffer to the network device. The determination method of the "high priority data" can be: based on logical channel group determination, i.e. all available data (available data, i.e. data already in the buffer) of the logical channels with higher priority than the second logical channel in the first logical channel group.

[0343] The "available data" here can only include non-delay-sensitive data (such as non-Delay-critical UL data), or simultaneously include delay-sensitive data (such as Delay-critical UL data) and non-Delay-critical UL data.

[0344] The first logical channel group specifically includes at least one of the following:

[0345] The logical channel group to which the logical channel triggering DSR belongs;

[0346] The logical channel group to which the logical channel having Delay-critical UL data to be reported belongs;

[0347] The logical channel group having Delay-critical UL data to be reported;

[0348] The logical channel group in which there is no logical channel triggering DSR, but the priority of at least one logical channel having available data in the logical channel group is higher than that of the logical channel triggering DSR.

[0349] The logical channel group in which there is no logical channel having Delay-critical UL data to be sent, but the priority of at least one logical channel having available data in the logical channel group is higher than that of the logical channel having Delay-critical UL data to be sent.

[0350] The second logical channel specifically includes at least one of the following:

[0351] The logical channel with the lowest priority among all logical channels belonging to the first logical channel group and triggering DSR;

[0352] The logical channel with the lowest priority among all logical channels belonging to the first logical channel group and having Delay-critical UL data to be reported;

[0353] The logical channel with the lowest priority among all logical channels triggering DSR of the terminal;

[0354] The logical channel with the lowest priority among all logical channels having Delay-critical UL data to be reported of the terminal.

[0355] For example, the terminal has multiple logical channel groups. For the first logical channel group (any one of the multiple logical channel groups), if there is a second logical channel triggering DSR in the logical channel group (the number of second logical channels can be one or more), the high-priority data refers to the available data of all logical channels in the logical channel group with a priority higher than that of the second logical channel.

[0356] For example, the terminal has multiple logical channel groups. For a first logical channel group (any one of the multiple logical channel groups), if there is no second logical channel triggering DSR in the logical channel group, but the priority of at least one logical channel with available data in the logical channel group is higher than that of the logical channel triggering DSR, the high-priority data refers to the available data of all logical channels with a priority higher than that of the second logical channel in the logical channel group of the terminal. The determination of the second logical channel can be, but is not limited to, any one of the following:

[0357] The logical channel with the lowest priority among all logical channels triggering DSR of the terminal.

[0358] The logical channel with the lowest priority among all logical channels with Delay-critical UL data to be reported of the terminal.

[0359] Step 604, the terminal reports the amount of Delay-critical UL data and the amount of high-priority data.

[0360] When the terminal reports the amount of high-priority data in the terminal buffer to the network device, the terminal reports the amount of high-priority data in the buffer corresponding to each first logical channel group based on each first logical channel group.

[0361] Specifically, the terminal can have two ways to report the amount of Delay-critical UL data and the amount of high-priority data, which are as follows:

[0362] Method A: The amount of high-priority data is reported to the network device by DSR MAC CE;

[0363] Method B: A separate MAC CE (referred to as the first MAC CE) is used for high-priority data reporting. The DSR MAC CE and the first MAC CE can be reported to the network device at the same time or by using adjacent uplink time-frequency resources.

[0364] For the way A, specifically, the terminal can report the data amount of high priority data to the network device through DSR MAC CE, and a field can be added in the existing DSR MAC CE to indicate the data amount of the high priority data (i.e., the first field). Optionally, a field can also be added to indicate the BS table corresponding to the data amount of the high priority data (i.e., the third field). Of course, if the BS table selected by the high priority data is the same as the BS table used by the DSR data of the logical channel group, the BS table indication field can be optionally carried for the high priority data. Considering that the LCG for reporting the DSR and the LCG for reporting the data amount of the high priority data can be different, an LCG indication field can also be added in the DSR MAC CE to indicate which LCG reports the data amount of the high priority data.

[0365] To distinguish the new DSR MAC CE from the existing DSR MAC CE, a new LCID can be introduced for the new DSR MAC CE. In addition, the R bit (i.e., the fourth field) in front of the Remaining Time field can be optionally used to indicate whether there is a field for indicating the data amount of the high priority data after the Remaining time. The schematic diagram of the new DSR MAC CE is shown in Figure 7 . The first byte is used to indicate which LCGs report the DSR data, and the second byte is used to indicate which LCGs report the high priority data.

[0366] For the way B, the first MAC CE needs to include a field for indicating the data amount of the high priority data based on each logical channel group. The first byte is used to indicate which LCGs report the high priority data. Optionally, a field can also be added to indicate the BS table corresponding to the data amount of the high priority data. An LCID can also be introduced for the first MAC CE to identify the first MAC CE. The schematic diagram of the first MAC CE is shown in Figure 8 .

[0367] For the way B, when the DSR is triggered, the first MAC CE is triggered to report.

[0368] When the terminal receives the UL resource allocation (i.e., UL scheduling permission, also known as UL grant), the terminal needs to perform LCP (Logical Channel Prioritization). The priority of the first MAC CE can be any one of the following:

[0369] The first MAC CE has a higher priority than the DSR MAC CE;

[0370] The priority of the first MAC CE is lower than the DSR MAC CE, but higher than the SL-BSR and / or other BSR MAC CEs except padding BSR;

[0371] The priority of the first MAC CE is lower than the SL-BSR and / or other BSR MAC CEs except padding BSR.

[0372] In addition, the first MAC CE cancellation condition includes any of the following:

[0373] The BSR is triggered within a time period after the DSR trigger to before the sending of the DSR MAC CE;

[0374] The uplink grant can carry all target data;

[0375] The DSR is cancelled;

[0376] MAC reset;

[0377] All latency-sensitive data is discarded;

[0378] The uplink grant can carry all latency-sensitive data;

[0379] The uplink grant can carry all available data of the terminal.

[0380] In addition, if the first MAC CE and / or the DSR MAC CE contains the amount of all available data of the terminal, the SR and / or BSR triggered by the terminal is cancelled.

[0381] Referring to Figure 9 , Figure 9 is a flowchart of an information processing method provided by an embodiment of the present application. In this embodiment, the amount of data of high-priority data is determined and reported based on a logical channel. The process can include:

[0382] Step 901, DSR trigger judgment.

[0383] Specifically, whether the DSR is triggered can be judged based on LCG or based on LCH.

[0384] If based on LCG, the DSR trigger condition is as follows:

[0385] If the minimum of the remaining time of the PDCP discardTimer corresponding to all SDUs in one LCG is less than the threshold, and the SDU corresponding to the PDCP discardTimer is not contained in the DSR MAC CE, and the current LCG has no pending DSR, the DSR is triggered for the LCG.

[0386] If based on LCH, the DSR triggering condition is as follows:

[0387] If the minimum of the remaining time of the PDCP discardTimer corresponding to all SDUs in one LCH is less than the threshold, and the SDU corresponding to the PDCP discardTimer is not contained in the DSR MAC CE, and the current LCH has no pending DSR, the DSR is triggered for the LCH.

[0388] Step 902, determine the data volume of delay-critical data in each LCG.

[0389] Before generating the DSR MAC CE, the terminal first needs to determine the data volume of the buffer corresponding to each LCG of the DSR to be reported. The data volume is the delay-critical UL data volume in the LCG.

[0390] Specifically, the Delay-critical UL data includes PDCP layer delay-critical PDCP data volume and delay-critical RLC data volume.

[0391] Wherein:

[0392] The PDCP layer delay-critical PDCP data volume includes:

[0393] Delay-critical PDCP SDU that has not generated PDCP data PDU;

[0394] PDCP data PDU containing delay-critical PDCP SDU and not submitted to the lower layer;

[0395] PDCP Control PDU;

[0396] For AM DRB, PDCP SDU to be retransmitted;

[0397] PDCP Data PDUs to be retransmitted for AM DRB.

[0398] RLC layer delay-critical RLC data volume includes:

[0399] delay-critical RLC SDUs and delay-critical RLC SDU segments that have not been generated into RLC PDUs;

[0400] RLC data PDUs containing delay-critical RLC SDUs or delay-critical RLC SDU segments that are waiting for initial transmission;

[0401] RLC data PDUs waiting for retransmission for RLC AM.

[0402] In the above description, the definitions of delay-Critical PDCP SDU and delay-critical RLC SDU are as follows:

[0403] Delay-critical PDCP SDU: If no PDU Set based discard mechanism is configured (i.e. parameter pdu-SetDiscard is not configured), the PDCP SDU whose discardTimer remaining time is less than the threshold is Delay-critical PDCP SDU. If PDU Set based discard mechanism is configured (i.e. parameter pdu-SetDiscard is configured), if at least one PDCP SDU within a PDU Set has discardTimer remaining time less than the threshold, all SDUs within the PDU Set are considered as Delay-critical PDCP SDU.

[0404] Delay-critical RLC SDU: If a PDCP PDU is indicated as delay-critical by PDCP, the RLC SDU related to this PDCP PDU is considered as Delay-critical RLC SDU.

[0405] In the above description, the definitions of delay-Critical PDCP SDU and delay-critical RLC SDU are as follows:

[0406] Delay-critical PDCP SDU: If no PDU Set based discard mechanism is configured (i.e. parameter pdu-SetDiscard is not configured), a PDCP SDU whose discardTimer remaining time is less than the threshold is a Delay-critical PDCP SDU. If PDU Set based discard mechanism is configured (i.e. parameter pdu-SetDiscard is configured), if at least one PDCP SDU within a PDU Set has discardTimer remaining time less than the threshold, all SDUs within the PDU Set are considered as Delay-critical PDCP SDU.

[0407] Delay-critical RLC SDU: If a PDCP PDU is indicated as delay-critical by PDCP, the RLC SDU associated with the PDCP PDU is considered as Delay-critical RLC SDU.

[0408] Step 903, determining the data amount of high priority data to be reported by the terminal.

[0409] Once the terminal has a DSR trigger, the terminal needs to report the data amount of high priority data (i.e. target data) in the terminal buffer to the network device.

[0410] The determination method of the "high priority data" can be: the available data (i.e. data already in the buffer) in each logical channel whose priority is higher than the priority of the first logical channel of the terminal.

[0411] The "available data" here can only include non-delay-sensitive data (such as non-Delay-critical UL data), or simultaneously include delay-sensitive data (such as Delay-critical UL data) and non-Delay-critical UL data.

[0412] The "first logical channel" specifically includes at least one of the following:

[0413] The logical channel with the lowest priority among all logical channels of the terminal triggering the DSR;

[0414] The logical channel with the lowest priority among all logical channels of the terminal having Delay-critical UL data to be reported.

[0415] Step 904, the terminal reports the amount of Delay-critical UL data and the amount of high priority data.

[0416] When the terminal reports the data amount of high-priority data in the terminal buffer to the network device, the terminal reports the data amount of the high-priority data based on each logical channel having high-priority data to be reported.

[0417] Specifically, there are two ways for the terminal to report the Delay-critical UL data amount and the data amount of the high-priority data, and the two ways are as follows:

[0418] Method A: The data amount of the high-priority data is reported to the network device by DSR MAC CE piggybacking.

[0419] Method B: A separate MAC CE (referred to as the first MAC CE) is used for high-priority data reporting for high-priority data, and the DSR MAC CE and the first MAC CE can be reported to the network device at the same time or reported to the network device by using adjacent uplink time / frequency resources.

[0420] For method A, specifically, the terminal can report the data amount of the high-priority data to the network device by DSR MAC CE piggybacking, and then a field can be added to the existing DSR MAC CE to indicate the data amount of the high-priority data in the logical channel that needs to report the high-priority data (i.e., the first field). Optionally, a field can also be added to indicate the BS table corresponding to the data amount of the high-priority data of the logical channel (i.e., the second field). Of course, if the BS table selected by the high-priority data is the same as the BS table used by the DSR data corresponding to the logical channel group to which the logical channel belongs, the BS table indicating field can also be omitted.

[0421] In order to distinguish the new DSR MAC CE from the existing DSR MAC CE, a new LCID can be introduced for the new DSR MAC CE. In addition, optionally, the R bit (i.e., the fourth field) in front of the Remaining Time field can be used to indicate whether there is a field for indicating the data amount of the high-priority data after the Remaining time. The schematic diagram of the new DSR MAC CE is shown in Figure 10 . The first byte is used to indicate which LCGs to report DSR data.

[0422] For method B, the first MAC CE needs to include a field (i.e., the second field) for indicating the data amount of the high-priority data based on each logical channel. Optionally, a field can also be added to indicate the BS table corresponding to the data amount of the high-priority data (i.e., the fifth field). An LCID can also be introduced for the first MAC CE to identify the first MAC CE. The schematic diagram of the first MAC CE is shown inFigure 11 is shown.

[0423] In addition, for the manner B, when the DSR is triggered, the first MAC CE is triggered to report.

[0424] When the terminal receives the UL resource allocation (i.e., UL scheduling permission, also referred to as UL grant), the terminal needs to perform LCP (Logical Channel Prioritization). The priority of the first MAC CE can be any one of the following:

[0425] The priority of the first MAC CE is higher than the DSR MAC CE;

[0426] The priority of the first MAC CE is lower than the DSR MAC CE, but higher than the SL-BSR and / or other BSR MAC CE except the padding BSR;

[0427] The priority of the first MAC CE is lower than the SL-BSR and / or other BSR MAC CE except the padding BSR.

[0428] In addition, the first MAC CE cancellation condition includes any one of the following:

[0429] The BSR is triggered within a time period after the DSR is triggered to the sending of the DSR MAC CE;

[0430] The uplink grant can carry all target data;

[0431] The DSR is cancelled;

[0432] The medium access control is reset;

[0433] All latency-sensitive data is discarded;

[0434] The uplink grant can carry all latency-sensitive data;

[0435] The uplink grant can carry all available data of the terminal.

[0436] In addition, if the first MAC CE and / or the DSR MAC CE contains the amount of all available data of the terminal, the SR and / or BSR triggered by the terminal is cancelled.

[0437] In the embodiments of the present application, it can be ensured that the network device can accurately know the amount of data that needs to be preferentially scheduled, so as to ensure that the network device allocates sufficient resources to carry the latency-sensitive service, and the high-priority data will not affect the transmission of the latency-sensitive service, thereby ensuring the transmission delay of the latency-sensitive service
