[0077] In order to better understand the technical solutions of the present application, the related concepts that can be involved in the embodiments of the present application are explained as follows.

[0078] Introduction of eXtended Reality (XR) service:

[0079] The XR service includes Augmented Reality (AR) service, Virtual Reality (VR) service and Mixed AR and VR (MR) service. At present, the popular XR service adopts H.264 encoding technology to realize image data compression, so as to save traffic and ensure image quality. The H.264 technology in the related art encodes image data into three types of image frames:

[0080] I frame (Intra-coded picture), which is a complete image frame, can generate and present images without dependence on other frames;

[0081] P frame (Predicted picture), which only contains image change information relative to the previous frame, and the receiver needs to combine the previous frame to generate the current frame and complete display on the receiving terminal;

[0082] B frame (Bidirectional predicted picture), which is used to indicate the change information of the current frame relative to the previous frame and the next frame, and the receiver needs to combine the previous frame and the next frame to generate the current frame.

[0083] The above-mentioned previous frame and next frame refer to the order of frame presentation time or image acquisition time of the source end. The actual sending and receiving time can be adjusted according to the image decoding time of the receiver, for example, the sender can send according to the image frame decoding time order of the receiver.

[0084] Different frame types correspond to different frame encoding methods, resulting in different degrees of image compression. Among them, the compression degree of I frame is low (i.e., the frame data amount is the largest), the compression degree of P frame is moderate (i.e., the frame data amount is moderate), and the compression degree of B frame is the highest (i.e., the frame data amount is the smallest).

[0085] There are two transmission modes for XR images, a transmission mode based on frame slice combination and a transmission mode based on a group of pictures (GoP).

[0086] The transmission combination mode based on slice combination: a data frame is cut into multiple data blocks, and the cut blocks of multiple image frames are dispersed and combined into multiple data blocks for transmission, achieving the purpose of smooth XR service data stream flow. This method greatly reduces the flow fluctuation caused by the difference in I / P / B frame data volume, but significantly increases the transmission delay of image frames due to cross-transmission between graphic frames.

[0087] The transmission mode based on frame set: according to the periodicity of the video stream, the video frames are divided into video frame combinations according to the period of I frames. An I frame and all P frames and B frames before the next I frame constitute a frame combination. Image frames are transmitted and played at the receiving end according to the frame period. The time interval between the arrival times of adjacent image frames is a frame period. The transmission mode based on frame set avoids the mixed transmission between image frames, so that the generated image frames are transmitted in time. Due to the different compression levels between I, P and B frames, the frame data rate fluctuates.

[0088] Protocol data unit set (PDU set) definition of XR service:

[0089] Currently, in the related discussions of the 3rd Generation Partnership Project (3GPP), the service data of XR is modeled as a PDU set, which includes a group of PDUs for quality of service (QoS) management when data is transmitted in a wireless network. According to the above different video data transmission modes, one PDU set can correspond to one image frame, such as a complete P frame or B frame, or an XR service data slice; in addition, one image frame can contain several PDU sets, such as when the left and right eye views of an image are transmitted separately, the left eye image data of an image corresponds to one PDU set, and the right eye image data corresponds to another PDU set; in addition, when the image is transmitted in the direction of the viewing axis and the non-viewing axis, the viewing axis direction image data corresponds to one PDU set, and the non-viewing axis direction image data corresponds to another PDU set. The above is only an example of PDU set modeling, and other forms of PDU set modeling are possible, which do not constitute a limitation on the implementation of the present application.

[0090] Transmission of XR service in NR network

[0091] According to the current 3GPP protocol, when an uplink XR data packet of a UE arrives at the Packet Data Convergence Protocol (PDCP) layer buffer from the application layer, the PDCP discard timer is started according to the initial value of the base station provisioning value. During the running of the PDCP discardTimer, the base station can schedule the UE to transmit the data packet to the base station. If the corresponding PDCP discardTimer expires and the data is still not successfully transmitted, the data packet is discarded.

[0092] Packet Delay Budget (PDB) of data

[0093] Different services have different Quality of Service (QoS) management requirements. In the 3GPP network, the QoS parameters include service data rate requirements, service data transmission delay requirements, and service data transmission reliability requirements (such as packet loss rate), etc. The network can set different QoS parameters according to the user experience targets of different services.

[0094] For latency-sensitive services, the end-to-end latency requirement is generally strict. According to the end-to-end latency requirement, the latency budget of each segment of the data transmission path is determined. When the latency-sensitive service data is transmitted through the air interface of 3GPP, the network determines the corresponding air interface latency budget, and schedules resources to ensure that the data is transmitted through the air interface within the given latency budget.

[0095] According to the current protocol, the PDB / PDU set delay budget (PSDB) window of a data packet can be understood as the running time window of the corresponding PDCP discardTimer, that is, the time window between the start of the PDCP discardTimer and the expiration of the PDCP discardTimer. If the corresponding data packet is still not successfully transmitted when the PDCP discardTimer expires, the PDCP entity will discard the PDCP PDU or the corresponding Radio Link Control (RLC) PDU that has not been successfully transmitted.

[0096] When transmitting XR image data, the network can configure data transmission based on PDU set. At this time, the network can configure the air interface transmission delay budget of the PDU set, PDU set Delay Budget (PSDB). The data packets contained in a PDU set correspond to the transmission window determined according to the PSDB. According to the current conclusion, the network can configure the corresponding PDCP discardTimer of the UE according to the PSDB, which is used to determine the transmission window of the PDU set or the data packets belonging to the PDU set.

[0097] Delay status reporting and uplink delay emergency data:

[0098] In R18, the protocol supports delay status reporting by logical channel group (LCG). When the remaining delay budget of the data with the minimum remaining delay budget in an LCG is lower than a preconfigured threshold (remainingTimeThreshold), the delay status reporting (DSR) of the LCG can be triggered. The data in an LCG whose remaining delay budget is lower than the preconfigured threshold is called delay emergency data. In the delay status report of an LCG, the UE indicates the remaining delay budget of the data with the minimum remaining delay budget in the LCG and the amount of buffered data whose remaining delay budget is lower than the preconfigured threshold. In the standard of R18, when an LCG triggers delay status information reporting, only one pair of remaining delay budget value and corresponding delay emergency data amount is reported.

[0099] In the PDCP protocol, the PDCP entity corresponding to a logical channel (LCH) determines the remaining delay budget of a data packet based on the remaining time of the discardTimer of the data packet.

[0100] FIG. 1b is the DSR format defined in R18, where LCGi (i is 0-7) indicates whether the delay status information of LCG i is included in the DSR. The delay status information of an LCG includes:

[0101] BT indicates whether the buffer status report (BSR) table uses the table defined in the protocol before R18 or the new BSR table defined in R18;

[0102] Remaining delay budget Remaining Time;

[0103] The amount of data corresponding to the delay emergency data.

[0104] In the related discussion, it has been agreed to support configuring multiple remaining time budget reporting thresholds for one LCG, corresponding to multiple remaining time budget ranges, which can be used to generate time status information containing multiple pairs of "remaining time budget and corresponding data volume" for the LCG. As an example, when N remaining time budget reporting thresholds (RRTT) are configured for LCG 1 of the UE, from low to high, they are: RRTT1, RRTT2, …, RRTTN, then at most N pairs of "remaining time budget and corresponding data volume" of time status information can be reported for LCG1, where the first pair corresponds to the remaining time budget of the data packet with the minimum remaining time budget in the data with a remaining time budget less than RRTT1 and the data volume in the data with a remaining time budget less than RRTT1; the nth (n > 1) pair corresponds to the remaining time budget of the data packet with the minimum remaining time budget in the data with a remaining time budget in the range [RRTTn-1, RRTTn) and the data volume of the data with a remaining time budget in the range.

[0105] In the related art, multiple remaining time budget thresholds have been supported for one LCG, which are used to generate multiple pairs of remaining time budget and corresponding data volume (i.e., multiple pairs of time status information) for the LCG, so as to report more detailed time status information generated and reported for the LCG, facilitating the base station to arrange uplink radio resources.

[0106] With this improvement, a new DSR medium access control control element (MAC CE) is introduced to support reporting multiple pairs of time status information for one LCG, which can report time status information with finer granularity, but also generates more overhead. If the UE of R19 always uses the new DSR format, more overhead will be generated than using the R18 DSR format. According to the newly introduced R19, multiple pairs of time status information are supported for one LCG (each pair of time status information includes a remaining time budget and a corresponding data volume) reporting; each pair of time status information includes: a remaining time budget, a corresponding data volume, a BSR table indication, etc.; if the base station configures Nm pairs of time status information reporting for M LCGs of the UE respectively, at most For time status information, the overhead is greatly increased compared to at most M pairs of time status information according to R18, when there is at most one pair of time status information for one LCG. In view of the above problem, the present application provides a time status information reporting method.

[0107] The time status information reporting method, device and other related equipment provided by the embodiments of the present application will be described in detail below in combination with the drawings and some embodiments and their application scenarios.

[0108] Please refer to FIG. 2, which is a flow chart of a method for reporting latency status information according to an embodiment of the present application. The method is applied to a terminal. As shown in FIG. 2, the method comprises the following steps:

[0109] In step 201, when the DSR of an LCG of the terminal is triggered, the terminal performs a first operation, which comprises at least one of the following:

[0110] When a first condition is met, the terminal reports the latency status information of the LCG in a first information format;

[0111] When the first condition is not met, the terminal reports the latency status information of the LCG in a second information format.

[0112] The first condition comprises at least one of the following:

[0113] At least one LCG of the terminal is pre-configured to report a plurality of pairs of latency status information respectively;

[0114] At least one LCG of the terminal is pre-configured to report a plurality of pairs of latency status information respectively, and one or more LCGs of the at least one LCG trigger the DSR;

[0115] Any one or more LCGs of the terminal need to report a plurality of pairs of latency status information respectively;

[0116] The first information format supports that one LCG reports at most M pairs of latency status information, the second information format supports that one LCG reports one pair of latency status information, and M is an integer greater than 1.

[0117] It should be noted that the DSR is triggered when the remaining latency budget of the data with the smallest remaining latency budget of one LCG is lower than a pre-configured threshold.

[0118] In the embodiments of the present application, when the DSR of an LCG of the terminal is triggered, the terminal needs to report the latency status information of the LCG. At this time, if the first condition is met, the terminal reports the latency status information of the LCG in the first information format. Exemplarily, when the DSR is triggered, the terminal reports the latency status information of the LCG in the first information format in the following cases:

[0119] 1) At least one LCG of the terminal is pre-configured to report a plurality of pairs of latency status information respectively;

[0120] 2) At least one LCG of the terminal is pre-configured to report a plurality of pairs of latency status information respectively, and one or more LCGs of the at least one LCG trigger the DSR.

[0121] 3) the terminal has at least one LCG pre-configured to report multiple pairs of latency status information, and one or more LCGs of the at least one LCG need to report multiple pairs of latency status information respectively;

[0122] 4) the terminal has at least one LCG pre-configured to report multiple pairs of latency status information, and one or more LCGs of the at least one LCG trigger DSR reporting and need to report multiple pairs of latency status information respectively.

[0123] The first information format supports that one LCG reports up to M pairs of latency status information, and M is an integer greater than 1. That is, in the case of meeting the first condition, the terminal reports in the first information format, that is, the terminal can support reporting multiple pairs of latency status information for one LCG, so as to report more detailed latency status information, which is more helpful for the network side device to arrange uplink radio resources based on the latency status information reported by the terminal.

[0124] Need to be explained, in the embodiments of the present application, the plurality refers to at least two, and the reporting can also be expressed as reporting. In some cases, multiple pairs of latency status information can also be referred to as multiple pairs of latency status information, and the latency status information includes residual latency budget, corresponding data volume, BSR table indication, etc.

[0125] If the first condition is not met, the terminal reports the latency status information of the LCG in the second information format. It can be understood that the case of meeting the first condition has been described above, and the case of not meeting the first condition can include at least one of the following:

[0126] The terminal has no LCG pre-configured to report multiple pairs of latency status information;

[0127] The terminal has no LCG that needs to report multiple pairs of latency status information;

[0128] The terminal has at least one LCG pre-configured to report multiple pairs of latency status information, and no LCG of the at least one LCG triggers DSR;

[0129] The terminal has at least one LCG pre-configured to report multiple pairs of latency status information, and the LCG triggering DSR of the at least one LCG does not need to report multiple pairs of latency status information.

[0130] The second information format supports one LCG reporting one pair of latency state information. Exemplarily, if the terminal does not have multiple pairs of latency state information configured by the LCG for reporting, the LCG is configured with only one pair of latency state information for reporting, the terminal reports in the second information format; or the LCG of the terminal is configured with multiple pairs of latency state information for reporting, but no LCG triggers the DSR, the terminal also reports in the second information format, that is, each LCG reports one pair of latency state information, or the LCG triggering the DSR does not need to report multiple pairs of latency state information, and the terminal also reports one pair of latency state information for the LCG. That is, for the above-mentioned case not satisfying the first condition, the terminal reports the latency state information in the second information format, that is, the terminal reports one pair of latency state information for each LCG, which can effectively reduce the reporting overhead of the terminal.

[0131] In the embodiment of the application, the first information format and the second information format are designed for the format of the terminal LCG reporting the pair of latency state information, in the case that the LCG DSR of the terminal is triggered, the terminal can determine to report the latency state information of the LCG in the first information format or the second information format according to whether the pre-configuration of the pair of latency state information of the LCG and the triggering of the DSR satisfy the first condition, that is, whether to report multiple pairs of latency state information or one pair of latency state information for the LCG, so that the reporting mode of the terminal for the latency state information of the LCG is more flexible, and the second information format with smaller overhead can be selected for reporting in the case not satisfying the first condition, thereby effectively saving the reporting overhead of the terminal.

[0132] Optionally, the first information format includes first indication information, and in the latency state report generated based on the first information format, the first indication information is used to indicate at least one of the following:

[0133] The correspondence between the LCG configured with multiple pairs of latency state information and the pair of latency state information;

[0134] The existence of each pair of latency state information of the LCG configured with multiple pairs of latency state information.

[0135] When the network side device pre-configures multiple pairs of latency state information for reporting for one LCG, some pairs of latency state information corresponding to the data amount of 0 do not need to be reported when the terminal generates the DSR for the LCG. At this time, if the pair of latency state information with the data amount of 0 is reported, 2 bytes will still be occupied, which causes the occupation of the reporting capacity of the latency state information.

[0136] In the embodiments of the present application, the first information format supports one LCG reporting multiple pairs of latency state information, and the first indication information in the first information format can be used to indicate whether each of the multiple pairs of latency state information of one LCG configured with the multiple pairs of latency state information exists, for example, for the pairs of latency state information with a data amount of 0, the first indication information can indicate that these pairs of latency state information do not exist, i.e., do not need to be reported, and the capacity occupied by the first indication information is much less than the total capacity occupied by the pairs of latency state information with a data amount of 0, thereby effectively saving the reporting overhead of the terminal.

[0137] In addition, the first indication information can also be used to indicate the correspondence between one LCG configured with multiple pairs of latency state information and the pairs of latency state information. It can be understood that the first information format supports one LCG reporting multiple pairs of latency state information, and the first indication information is used to indicate which LCG the certain pair of latency state information corresponds to, thereby making the relationship between the pairs of latency state information reported by the terminal and the LCG more clear.

[0138] Optionally, the first indication information is indicated by at least one of the following:

[0139] a bitmap;

[0140] the number of pairs of latency state information;

[0141] a spare bit in the pair of latency state information.

[0142] Exemplarily, the first indication information is indicated by a bitmap. In the DSR MAC CE, for each LCG reporting at least one pair of latency state information, a bitmap is used to indicate whether the pair of latency state information corresponding to the LCG exists. According to this method, the number of bitmap bits occupied by one LCG is equal to the number of the maximum reportable pairs of latency state information. For example, Nm pairs of latency state information are configured for M LCGs of a terminal, and the terminal has a maximum of pairs of latency state information, at least bitmap fields of bits are needed.

[0143] Optionally, in the case where the first indication information is indicated by a bitmap, each first LCG has a corresponding bitmap, and the bitmap is located before the latency state information domain of the first LCG corresponding thereto, or all the bitmaps corresponding to the first LCGs are collectively located before the latency state information domains of the first LCGs; wherein the first LCG is any LCG reporting at least one pair of latency state information or an LCG configured with multiple pairs of latency state information.

[0144] In one embodiment, as shown in Fig. 3a, the bitmap corresponding to one LCG is placed before the time delay status information field of the LCG. It should be noted that according to the byte alignment of the MAC CE design, a bitmap of less than 8 bits of one LCG occupies one byte, which results in some reserved bits and a space overhead.

[0145] In another embodiment, as shown in Fig. 3b, the centralized bitmap of 8 LCGs is shown, which is placed before the time delay status information field of all the LCGs and occupies 3 bytes. In this embodiment, the bitmaps of all the LCGs are centralized to form a longer bitmap, so as to avoid the byte fragmentation caused by the bitmaps of different LCGs placed in different areas in the previous embodiment, and the byte occupation is smaller, which effectively saves the capacity of the time delay status information of the LCGs reported by the terminal.

[0146] Optionally, the first indication information can also be the number of time delay status information pairs. In the DSR MAC CE, for each LCG having at least one pair of time delay status information reported, there is a number of time delay status information pairs corresponding to the number of time delay status information pairs of the LCG included in the DSR MAC CE. For one LCG, the number of bits occupied by the indication of the number of time delay status information pairs does not exceed the number of bits occupied by the bitmap indication. Assuming that the bitmap of LCG m occupies Nm bits based on the bitmap indication, the number of time delay status information pairs occupies Furthermore, the indication of the number of time delay status information pairs can more effectively save the reporting overhead of the time delay status information.

[0147] Optionally, in the case where the first indication information is indicated by the number of time delay status information pairs, each second LCG has a corresponding number indication, and the number indication is used to indicate the number of time delay status information pairs of the second LCG; wherein the second LCG is any LCG having at least one time delay status information pair to be reported or an LCG configured with multiple time delay status information pairs.

[0148] It can be understood that if there is a number indication of time delay status information pairs in the time delay status information field of an LCG, it means that the LCG has time delay status information pairs and the number of corresponding time delay status information pairs; if there is no number indication of time delay status information pairs, it means that the LCG has no time delay status information pair to be reported.

[0149] Optionally, each second LCG has a corresponding quantity indication, which is located before the latency state information field of the second LCG corresponding thereto, or all second LCGs have their respective corresponding quantity indications collectively located before the latency state information fields of all second LCGs.

[0150] That is, in the case where the first indication information indicates the number of latency state information pairs, each LCG includes a corresponding quantity indication, which can be placed separately, i.e., each LCG has its respective corresponding quantity indication located before the latency state information field of the LCG, or can be placed collectively, i.e., all LCGs have their respective corresponding quantity indications collectively placed before the latency state information fields of all LCGs. The method of collective placement can avoid fragmenting the byte field of the DSR MAC CE and is conducive to improving the use efficiency.

[0151] Optionally, in the case where the first indication information indicates the number of latency state information pairs or the bitmap, the terminal determines the word length of the bitmap or the word length of the quantity indication of the latency state information pairs based on the number of latency state information reporting thresholds or the maximum number of latency state information pairs preconfigured by the network side device for each LCG.

[0152] Exemplarily, in the case where the first indication information is indicated based on the bitmap, the terminal can determine the length of the bitmap segment corresponding to each LCG based on the number of latency state information reporting thresholds or the maximum number of latency state information pairs preconfigured by the network side device for each LCG; in the case where the first indication information is indicated based on the number of latency state information pairs, the terminal can determine the word length of the quantity indication of the latency state information pairs corresponding to each LCG based on the number of latency state information reporting thresholds or the maximum number of latency state information pairs preconfigured by the network side device for each LCG.

[0153] Optionally, in the case where a third LCG is preconfigured with one latency state information reporting threshold or at most one latency state information pair, the first information format does not use the bitmap or the number of latency state information pairs to indicate whether the latency state information pair of the third LCG exists; wherein the third LCG is any LCG.

[0154] For example, in the case that the first indication information is indicated based on a bitmap, when one LCG is pre-configured with one delay state information reporting threshold or at most one pair of delay state information, the bitmap field is not used in the DSR MAC CE to indicate whether the pair of delay state information is contained in the DSR MAC CE, because the network side device can determine that the pair of delay state information of the LCG is contained in the DSR MAC CE based on the setting of the corresponding bit in the LCG bitmap, and no additional indication is needed, thereby saving the reporting overhead of the terminal.

[0155] In the case that the first indication information is indicated based on the number of pairs of delay state information, when one LCG is pre-configured with one delay state information reporting threshold or at most one pair of delay state information, the number of pairs of delay state information field is not used in the DSR MAC CE to indicate whether the pair of delay state information is contained in the DSR MAC CE, because the network side device can determine that the pair of delay state information of the LCG is contained in the DSR MAC CE based on the setting of the corresponding bit in the number of pairs of delay state information of the LCG, and no additional indication is needed, thereby saving the reporting overhead of the terminal.

[0156] In the embodiments of the present application, the first indication information can also be indicated by the spare bit in the pair of delay state information. Optionally, in the case that the first indication information is indicated by the spare bit in the pair of delay state information, the spare bit is used to indicate the corresponding relationship between the LCG configured with multiple pairs of delay state information and the pair of delay state information, thereby achieving effective utilization of the spare bit in the delay state information.

[0157] In the embodiments of the present application, in the delay state report generated based on the first information format, the spare bit in the pair of delay state information is used to indicate the first indication information, that is, to indicate the corresponding relationship between the LCG configured with multiple pairs of delay state information and the pair of delay state information (such as S=1, S=0 in FIG. 3c, or E=1, E=0 in FIG. 3d); in the delay state report generated based on the second information format, the spare bit in the pair of delay state information has no indication significance and only represents a spare bit (such as R in FIG. 1b). That is, the first information format is equivalent to newly defining the spare bit in the pair of delay state information, thereby achieving effective utilization of the parameters in the pair of delay state information.

[0158] Optionally, the spare bit includes a target value, in a case where the two adjacent latency status information pairs belong to the same LCG, the spare bits corresponding to the two adjacent latency status information pairs include the same target value; in a case where the two adjacent latency status information pairs do not belong to the same LCG, the spare bits corresponding to the two adjacent latency status information pairs include different target values.

[0159] In this embodiment, whether the target parameters of the spatial domain bits are the same is used to indicate whether the two adjacent latency status information pairs belong to the same LCG. For example, referring to FIG. 3c, the LCG bitmap is 00010101, indicating that the latency status information of LCG 4, LCG 2 and LCG 0 is contained in the DSR MAC CE, and the latency status information pairs are arranged in the DSR MAC CE in descending order of the corresponding LCG ID; it is assumed that the latency status information pairs of LCG 4, LCG 2 and LCG 0 are 2 pairs, 1 pair and 2 pairs respectively, and whether the target values of the spare bits in each latency status information pair are the same is used to determine whether a latency status information pair corresponds to the same LCG as the previous latency status information pair or the next LCG. As shown in FIG. 3c, for LCG 4, the target values in the spare bits of the two adjacent latency status information pairs are both S=1, indicating that the two latency status information pairs belong to the same LCG; the target value in the spare bits of the next latency status information pair (corresponding to LCG 2) is S=0, indicating that the latency status information pair does not belong to the same LCG as the previous adjacent latency status information pair, and the target value in the spare bits of the next latency status information pair (corresponding to LCG 0) is S=1, indicating that the two adjacent latency status information pairs do not belong to the same LCG.

[0160] Alternatively, in another embodiment, the spare bit includes a first value and a second value, in a case where the first latency status information pair is the last latency status information pair of an LCG, the spare bit corresponding to the first latency status information pair includes the first value; in a case where the first latency status information pair is not the last latency status information pair of an LCG, the spare bit corresponding to the first latency status information pair includes the second value; the first value is different from the second value.

[0161] For example, referring to FIG. 3d, for example, the LCG bitmap is 00010101, indicating that the latency status information of LCG 4, LCG 2 and LCG 0 is contained in the DSR MAC CE, and the latency status information is arranged in the DSR MAC CE in descending order of the corresponding LCG ID; assuming that the latency status information pairs of LCG 4, LCG 2 and LCG 0 are 2 pairs, 1 pair and 2 pairs respectively, E=0 (the second parameter) in the spare bit indicates that the latency status information pair is not the last latency status information pair of an LCG, and E=1 (the first value) in the spare bit indicates that the latency status information pair is the last latency status information pair of an LCG. Further, based on whether the spare bit in each latency status information pair includes the first value or the second value, it can be determined whether the latency status information pair is the last latency status information pair of the corresponding LCG, and whether the latency status information pair and the last adjacent latency status information pair belong to the same LCG.

[0162] In the embodiments of the present application, by setting the constant value in the spare bit in the latency status information pair, it can be determined whether the latency status information pair and the adjacent latency status information pair belong to the same LCG, so that the correspondence between the latency status information pair and the LCG can be indicated by the spare bit. In this way, the spare bit in the latency status information pair is effectively utilized, and no additional bits are required to indicate the correspondence between the latency status information pair and the LCG, which is more helpful to save the reporting overhead of the terminal.

[0163] Optionally, the method further comprises:

[0164] In the case that the terminal is configured to report the DSR based on the PDU set, for any PDU set, the terminal determines the remaining latency budget reporting threshold or the range of the remaining latency budget corresponding to the PDU set according to the PDU with the shortest remaining latency budget among the remaining PDUs of the PDU set, and counts the data amount of all the remaining PDUs of the PDU set into the data amount corresponding to the remaining latency budget reporting threshold or the range of the remaining latency budget.

[0165] For example, assume that the terminal's LCG1 is configured with 3 remaining time thresholds for reporting: 15ms, 10ms and 5ms; LCH1 of LCG 1 carries a PDU set 1 with three remaining PDUs to be transmitted: PDU A, PDU B and PDU C, with corresponding remaining time budgets of 16ms, 12ms and 11ms respectively, and the shortest remaining time budget is 11ms, then the data volume of the three remaining PDUs to be transmitted (PDU A, PDU B and PDU C) of PDU set 1 are all counted into the data volume within the range of 15ms to 10ms of the remaining time budget. In this way, the calculation of the data volume of the PDU set carried by the LCG is redefined, ensuring that the data volume of the PDU set can be transmitted within the remaining time budget reporting threshold.

[0166] Optionally, in the embodiments of the present application, the DSR of the LCG of the terminal is triggered, including:

[0167] The data packet of one LCG of the terminal is not reported in any one of the time status information pairs reported in the previous DSR, and the remaining time budget of the LCG is lower than the remaining time budget threshold for triggering the DSR, and the DSR of the LCG is triggered.

[0168] Exemplarily, in the case that the data packet of one LCG is reported in any one of the time status information pairs reported in the previous DSR, when the remaining time budget of the data packet becomes lower than the remaining time budget threshold for triggering the DSR as time elapses, the DSR is not triggered. That is, only in the case that the data packet of one LCG is not reported in any one of the time status information pairs reported in the previous DSR, and its remaining time budget is lower than the remaining time budget threshold for triggering the DSR, the DSR can be triggered. For the data that has been reported in the DSR before, the network side device can infer the remaining time of the data packet according to the DSR received before, and thus does not need to be reported, thereby saving the DSR reporting overhead.

[0169] Optionally, after the DSR of one LCG of the terminal is triggered, the method further includes:

[0170] The terminal generates the DSR for the LCG, and determines that there is no at least one time status information pair of the LCG that needs to be reported, and cancels the DSR reporting of the LCG.

[0171] In the embodiments of the present application, when one LCG determines to trigger DSR according to the remaining delay budget threshold for triggering DSR, and it is determined that there is no at least one pair of latency status information to be reported when generating DSR for the LCG, i.e., there is no any pair of latency status information to be reported, the DSR reporting of the LCG is cancelled; that is, in the case that all LCHs of the LCG have no at least one data packet matching any remaining delay budget reporting threshold, the DSR reporting is cancelled.

[0172] For example, LCG1 of the terminal is configured with three remaining delay budget reporting thresholds: 15 ms, 10 ms and 5 ms; there are PDU set 1 and PDU set 2, the remaining delay budget of PDU set 1 corresponds to the range of remaining delay budget reporting thresholds 15 ms to 10 ms, and the remaining delay budget of PDU set 2 corresponds to the range of remaining delay budget reporting thresholds 5 ms to 0 ms; when the terminal performs the DSR generation process, if it is found that PDU set 1 and PDU set 2 have been put into the MAC PDU, the DSR is cancelled; if only PDU set 2 is put into the MAC PDU, and PDU set 1 is left, the latency status information pair corresponding to PDU set 1 is reported. In other words, when one LCG of the terminal triggers DSR, if at least one pair of latency status information needs to be reported, regardless of whether the reported latency status information pair is the latency status of latency urgent data or non-latency urgent data, the terminal needs to include the latency status information of the LCG when generating the DSR MAC CE.

[0173] In the embodiments of the present application, the cancellation condition of DSR reporting is defined, which can cancel the DSR reporting of the LCG in the case that there is no any pair of latency status information of the LCG to be reported, thereby saving the reporting overhead of the terminal.

[0174] Optionally, the method further includes at least one of the following:

[0175] The terminal determines the remaining delay budget threshold for triggering the DSR reporting of the LCG as one remaining delay budget reporting threshold of the LCG;

[0176] The terminal determines the remaining delay budget threshold for triggering the DSR reporting of the LCG as the minimum remaining delay budget reporting threshold of the LCG.

[0177] In this way, the remaining delay budget reporting threshold and the minimum remaining delay budget reporting threshold of the LCG are defined to ensure that the pair of latency status information of the LCG can be reported within the minimum remaining delay budget reporting threshold.

[0178] Optionally, the method further includes at least one of the following:

[0179] The terminal determines data based on the minimum remaining delay budget reporting threshold as delay urgent data.

[0180] In a case where the network side device configures the terminal with other remaining delay budget reporting thresholds for the LCGs, the terminal determines data based on the other remaining delay budget reporting thresholds as non-delay urgent data.

[0181] In this way, the terminal can determine which data is delay urgent data and which data is non-delay urgent data, and the terminal can preferentially report the delay urgent data to ensure that the delay urgent data can be reported.

[0182] Please refer to FIG. 4, which is a flowchart of another delay state information reporting method provided by an embodiment of the application, and the method is applied to a network side device. As shown in FIG. 4, the method includes the following steps:

[0193] Optionally, the first information format comprises first indication information, and in the latency state report generated based on the first information format, the first indication information is used to indicate at least one of the following:

[0194] A correspondence between an LCG configured with a plurality of latency state information pairs and a latency state information pair.

[0201] The first LCG is an LCG with at least one latency state information pair to be reported or an LCG configured with a plurality of latency state information pairs.

[0202] Optionally, in a case where the first indication information is indicated by a number of latency state information pairs, each second LCG has a corresponding number indication, and the number indication is used to indicate a number of latency state information pairs of the second LCG.

[0204] Optionally, in the case that the first indication information is indicated by the bitmap or the number of the time delay state information pairs, the terminal determines the bit length of the bitmap or the bit length indicated by the number of the time delay state information pairs based on the number of the time delay state information reporting thresholds or the maximum number of the time delay state information pairs of each LCG preconfigured by the network side device.

[0205] Optionally, in the case that the third LCG is preconfigured with one time delay state information reporting threshold or at most one time delay state information pair, the first information format does not use the bitmap or the number of the time delay state information pairs to indicate whether the time delay state information pair of the third LCG exists; wherein the third LCG is any LCG.

[0206] Optionally, in the case that the first indication information is indicated by the spare bit in the time delay state information pair, the spare bit is used to indicate the corresponding relationship between the LCG configured with multiple time delay state information pairs and the time delay state information pair.

[0209] It should be noted that the time delay state information reporting method provided by the embodiments of the present application is applied to the network side device, and is a pair of transceiving relationship with the above-mentioned method applied to the terminal. The related concepts and specific implementation processes involved in the embodiments of the present application can be referred to the description of the above-mentioned terminal method embodiments, which will not be described here.

[0210] In the embodiments of the present application, the network side device can receive the time delay state information reported by the terminal in the first information format and / or the second information format. The terminal can determine to report the time delay state information of the LCG in the first information format or the second information format according to whether the pre-configuration of the time delay state information pair of the LCG and the triggering of the DSR satisfies the first condition, that is, the terminal can select whether to report multiple time delay state information pairs or one time delay state information pair for the LCG, so that the reporting manner of the terminal for the time delay state information of the LCG is more flexible, and the terminal can select the second information format with smaller overhead to report in the case of not satisfying the first condition, thereby effectively saving the reporting overhead of the terminal.

[0211] The time delay state information reporting method provided in the embodiments of the present application can be executed by the time delay state information reporting device.
