Method for reporting delayed status and related device

[0001] The present application claims priority from the Chinese patent application No. 202411342157.2 filed on September 24, 2024, and entitled "Method for reporting delayed status and related device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, in particular to a method for reporting delayed status and related device. BACKGROUND

[0003] In extended reality (XR) or protocol data unit (PDU) services waiting for retransmission, there are characteristics such as arrival time jitter, variable packet size, multi-flow services, and large data volume. If the data packet to be sent cannot be scheduled or cannot be scheduled in time, the network needs to be reported the situation of the data packet to be sent.

[0004] In the prior art, a delayed status report (DSR) mechanism and an enhanced delayed status report (EDSR) mechanism are introduced; the DSR mechanism reports only a set of minimum residual time and related buffer data volume for one logical channel group (LCG), and the EDSR mechanism can report multiple sets of residual time and related buffer data volume for one LCG. However, there is no clear distinction between the two delayed status reporting mechanisms in specific use. SUMMARY

[0005] The present application provides a method for reporting delayed status and related device, aiming to distinguish between the use of the DSR mechanism and the EDSR mechanism.

[0006] To achieve the above object, the present application provides the following technical solutions:

[0007] The first aspect of the present application provides a method for reporting a delay state, which is applied to a terminal device, and the method comprises: performing reporting of an enhanced delayed status report (EDSR) according to a remaining time and reporting configuration information; wherein the remaining time is a remaining time of a data packet to be transmitted in a logical channel group (LCG) or a logical channel (LCH), and the enhanced delayed status report comprises at least one set of delay information of the LCG or the LCH, and the delay information comprises remaining time information and / or data volume information.

[0008] The embodiment first provides a use mechanism of the enhanced delayed status report from a triggering condition of the enhanced delayed status report. In the embodiment, the terminal device can perform reporting of the enhanced delayed status report according to a remaining time of a data packet to be transmitted and reporting configuration information, and the enhanced delayed status report comprises at least one set of delay information in the LCG or the LCH.

[0009] It should be noted that the remaining time involved in the embodiment can also be a remaining time of a protocol data unit set (PUD set). Correspondingly, the enhanced delayed status report (EDSR) can comprise at least one set of delay information of the PUD set. Therefore, the remaining time of the data packet to be transmitted in the LCG or the LCH in the embodiment can be replaced by the remaining time of the data packet to be transmitted in the LCG or the LCH or the remaining time of the PUD set, and the enhanced delayed status report (EDSR) comprising at least one set of delay information of the LCG or the LCH can be replaced by the enhanced delayed status report (EDSR) comprising at least one set of delay information of the LCG or the LCH or the PUD set.

[0010] The remaining time of the data packet to be transmitted is not limited in the embodiment, and the remaining time should be a value greater than zero. When the LCG or the LCH comprises more than one data packet to be transmitted, the remaining time can be a minimum value of the remaining time of all the data packets to be transmitted in the LCG or the LCH. For example, the remaining time can be a remaining time of a discard timer of the data packet to be transmitted, or a remaining time of a waiting timer of the data packet to be transmitted.

[0011] Unless otherwise specified, the terminal device in the present application can refer to the terminal device itself, a component (for example, a processor, a chip, or a chip system, etc.) in the terminal device, or a logical module or software capable of realizing all or part of the functions of the terminal device. The present application does not limit the execution subject of the method for acquiring system information.

[0012] In some possible implementation manners, the reporting configuration information comprises a reporting trigger threshold; the reporting trigger threshold is used to trigger the reporting of the execution of the enhanced delay status report, and the enhanced delay status report comprises at least one group of delay information with a remaining time less than or equal to the reporting trigger threshold.

[0013] The reporting configuration information comprises a reporting trigger threshold of the enhanced delay status report, the reporting trigger threshold is used to trigger the execution of the reporting of the enhanced delay status report, when the remaining time of the data packet to be transmitted is less than or equal to the reporting trigger threshold, the reporting of the enhanced delay status report is triggered, and the enhanced delay status report should comprise at least one group of delay information with a remaining time less than or equal to the reporting trigger threshold.

[0014] In some possible implementation manners, the reporting of the execution of the enhanced delay status report is triggered based on that the remaining time is less than or equal to the reporting trigger threshold.

[0015] In the embodiments of the present application, the enhanced delay status report can be configured with a corresponding reporting trigger threshold, the reporting trigger threshold of the enhanced delay status report is used to trigger the execution of the reporting of the enhanced delay status report, when the remaining time of the data packet to be transmitted is less than or equal to the reporting trigger threshold, the reporting of the enhanced delay status report is triggered.

[0016] In some possible implementation manners, the reporting configuration information further comprises a plurality of remaining time thresholds, the plurality of remaining time thresholds are used to configure the reporting trigger threshold; wherein the reporting trigger threshold is configured as a minimum value or a maximum value in the plurality of remaining time thresholds; or the reporting trigger threshold is configured as a specified remaining time threshold value in the plurality of remaining time thresholds.

[0017] In the embodiments of the present application, the enhanced delay status report can be configured with a plurality of remaining time thresholds, the plurality of remaining time thresholds can be used to configure the reporting trigger threshold of the enhanced delay status report, the reporting trigger threshold can be configured as any threshold value in the plurality of remaining time thresholds, for example, a maximum value, a minimum value or a specified threshold value. The skilled person can adaptively configure the reporting trigger threshold according to actual business requirements.

[0018] In some possible implementation manners, the data packets to be transmitted include at least one of the following: a data packet with a remaining time less than or equal to the reporting trigger threshold; a data packet belonging to a protocol data unit set, and the protocol data unit set including at least one data packet with a remaining time less than or equal to the reporting trigger threshold; a data packet with a remaining time less than or equal to a minimum value or a maximum value of the plurality of remaining time thresholds; a data packet belonging to a protocol data unit set, and the protocol data unit set including at least one data packet with a remaining time less than or equal to a minimum value or a maximum value of the plurality of remaining time thresholds; a data packet with a remaining time less than or equal to a specified remaining time threshold value of the plurality of remaining time thresholds; or a data packet belonging to a protocol data unit set, and the protocol data unit set including at least one data packet with a remaining time less than or equal to a specified remaining time threshold value of the plurality of remaining time thresholds.

[0019] In the embodiments of the present application, when at least one data packet in a protocol data unit set (PUD set) satisfies a condition that a remaining time is less than a configured reporting trigger threshold, all data packets in the protocol data unit set are delay-critical data packets. Since all data packets in the protocol data unit set will be discarded when one data packet in the protocol data unit set is discarded, when reporting delay information, when one data packet in the protocol data unit set is less than or equal to the reporting trigger threshold, all data packets in the protocol data unit set should be considered as delay-critical data packets and be reported together.

[0020] In some possible implementation manners, the data packet to be transmitted is not transmitted as a protocol data unit (PDU) of a medium access control (MAC) layer, the logical channel group (LCG) or the logical channel (LCH) does not perform reporting of an enhanced delay status report, a data amount of the data packet to be transmitted is not reported in the enhanced delay status report, or the data amount of the data packet to be transmitted is not reported in the delay status report and the enhanced delay status report.

[0021] In the requirement that the data packet to be transmitted is not transmitted as a protocol data unit (PDU) of a medium access control (MAC) layer, on one hand, it is ensured that the data packet to be transmitted is not reported to a network device even if a delay status report (DSR) is triggered, and on the other hand, since a data packet to be retransmitted has a relatively high priority, the data packet to be retransmitted is preferentially transmitted when there is an authorization, thereby ensuring that a data packet to be newly transmitted is transmitted.

[0022] The reporting of the LCG or LCH not performing the enhanced delay status reporting refers to the absence of a pending enhanced delay status report, i.e., an enhanced delay status report that is waiting to be sent but has not yet been sent, so that the repeated reporting of delay information can be avoided.

[0023] The data amount of the data packet to be transmitted is not reported in the previous enhanced delay status report, or the data amount of the data packet to be transmitted is not reported in the previous delay status report and the previous enhanced delay status report, so that the repeated sending of delay information can also be avoided, and since the delay information provided in the delay status report is not as rich as that in the enhanced delay status report, the reporting in the delay status report is optional, i.e., even if it is reported in the previous delay status report, the enhanced delay status report that can provide more rich delay information can still be reported.

[0024] It can be understood that those skilled in the art can adjust the limitation conditions of the data packet to be transmitted based on actual business needs, and the embodiments of the present application are not limited.

[0025] In some possible implementation manners, the method further includes: canceling the reporting of the enhanced delay status report based on a first canceling condition; wherein the first canceling condition includes at least one of the following conditions: the first data packet or the second data packet has been discarded; the first data packet or the second data packet has been transmitted as a protocol data unit (PDU) of a media access control (MAC) layer; the enhanced delay status report including the first data packet or the second data packet has been reported; a logical channel group (LCG) or a logical channel (LCH) associated with the first data packet or the second data packet triggers the reporting of the enhanced delay status report, and the first data packet or the second data packet has not been transmitted as a PDU of the MAC layer; wherein the remaining time of the first data packet is less than or equal to a reporting trigger threshold, and the remaining time of the second data packet is less than or equal to a maximum value of a plurality of remaining time thresholds.

[0026] In the case of meeting the corresponding conditions, the reporting of the enhanced delay status report can be canceled, for example: the data packet to be transmitted has been discarded, or the data packet to be transmitted has been transmitted as a PDU of the MAC layer, so that the reporting of the data packet to be transmitted is meaningless, and the reporting of the enhanced delay status report can be canceled at this time to avoid the reporting of meaningless delay information and waste of resources.

[0027] In some possible implementation manners, the method further includes: if the reporting of the delay status report is being performed, indicating, based on a first generation condition, to generate an enhanced delay status report; triggering, based on a first scheduling condition, a scheduling request SR, where the scheduling request SR is used to request an uplink shared channel UL-SCH resource for a new transmission; and wherein the first generation condition includes: the uplink shared channel UL-SCH resource includes a target resource for a new transmission, and the target resource is determined to be used to carry the enhanced delay status report based on a logical channel priority LCP result; and the first scheduling condition includes at least one of the following conditions: no scheduling request of the enhanced delay status report and / or no scheduling request of the delay status report is being processed; and a logical channel LCH corresponding to the triggering of the delay status report and / or the enhanced delay status report is a same logical channel LCH.

[0028] When the terminal device is performing the reporting of the delay status report, the terminal device can be instructed to generate an enhanced delay status report under a corresponding condition, for example: a logical channel group LCG or a logical channel LCH is processing a delay status report DSR, an uplink shared channel (UL-SCH) resource includes a target resource for a new transmission, and the target resource can carry an enhanced delay status report based on a logical channel priority LCP result, at which time a multiplexing and assembling process can be instructed to generate a media access control (MAC) control element (CE) corresponding to the enhanced delay status report EDSR.

[0029] In addition, a scheduling request (SR) can be triggered under a corresponding condition, for example: no scheduling request of the EDSR and / or no scheduling request of the DSE is being processed, and a logical channel corresponding to the triggering of the delay status report and / or the enhanced delay status report is a same logical channel, at which time the scheduling request SR can be triggered to request an uplink shared channel UL-SCH resource for a new transmission.

[0030] In some possible implementation manners, the reporting configuration information is configured through radio resource control (RRC) signaling.

[0031] In the embodiments of the present application, the reporting configuration information can be configured by a network device through radio resource control (RRC) signaling. Optionally, the reporting configuration information can also be configured by the network device through a MAC CE. Optionally, the reporting configuration information can be configured by the RRC signaling and the MAC CE.

[0032] The second aspect of the present application provides a method for reporting a delay status, which is applied to a terminal device, and the method comprises: performing reporting of a delayed status report (DSR) or performing reporting of an enhanced delayed status report (EDSR) according to a remaining time and reporting configuration information; wherein the remaining time is a remaining time of a data packet to be transmitted in a logical channel group (LCG) or a logical channel (LCH), the delayed status report comprises a set of delay information of the logical channel group (LCG) or the logical channel (LCH), and the enhanced delayed status report comprises at least a set of delay information of the logical channel group (LCG) or the logical channel (LCH), and the delay information comprises remaining time information and / or data volume information.

[0033] In the embodiments of the present application, the terminal device can perform reporting of a delayed status report or reporting of an enhanced delayed status report according to a remaining time of a data packet to be transmitted and reporting configuration information, a set of delay information in an LCG or an LCH is included in the delayed status report, and at least a set of delay information in the LCG or the LCH is included in the enhanced delayed status report. The embodiments combine the delayed status report and the enhanced delayed status report to provide a method for reporting a delay status.

[0034] It should be noted that the residual time involved in the embodiments of the present application can also be the residual time of a protocol data unit set (PUD set). Correspondingly, the delay status report (DSR) can include a set of delay information of the PUD set, and the enhanced delay status report (EDSR) can include at least a set of delay information of the PUD set. Thus, the residual time of the data packet to be transmitted in the logical channel group (LCG) or the logical channel (LCH) in the embodiments of the present application can be replaced by the residual time of the data packet to be transmitted in the logical channel group (LCG) or the logical channel (LCH) or the residual time of the PUD set, the set of delay information of the logical channel group (LCG) or the logical channel (LCH) in the delay status report can be replaced by the set of delay information of the logical channel group (LCG) or the logical channel (LCH) or the PUD set in the delay status report, and the at least a set of delay information of the logical channel group (LCG) or the logical channel (LCH) or the PUD set in the enhanced delay report, wherein the granularity of the PUD set can be based on the characteristics of the PUD set, and the characteristics of the PUD set are priority or importance level, or dependency relationship, etc. For example, the delay information based on the priority or importance level of the PUD set, when the importance level is level 1 or level 2, the at least a set of delay information of the PUD set is at least a set of delay information of the PUD set with the importance level 1, or the at least a set of delay information of the PUD set is at least a set of delay information of the PUD set with the importance level 2.

[0035] In the embodiments of the present application, the residual time of the data packet to be transmitted is not limited, and the residual time should be a value greater than zero. When the LCG or the LCH includes more than one data packet to be transmitted, the residual time can be the minimum value of the residual time of all the data packets to be transmitted in the LCG or the LCH. For example, it can be the residual time of the discard timer of the data packet to be transmitted, or it can be the residual time of the waiting timer of the data packet to be transmitted.

[0036] In the embodiments of the present application, the "terminal device" can refer to the terminal device itself, a component (for example, a processor, a chip, or a chip system, etc.) in the terminal device, or a logical module or software capable of realizing all or part of the sending end function. The execution subject of the system information acquisition method in the present application is not limited.

[0037] In some possible implementation manners, the logical channel group LCG is configured as a logical channel group LCG supporting the delayed status reporting, or the logical channel LCH is configured as a logical channel LCH supporting the delayed status reporting, and the performing of the reporting of the delayed status reporting or the performing of the reporting of the enhanced delayed status reporting according to the remaining time and the reporting configuration information comprises: performing the reporting of the delayed status reporting according to the remaining time and the reporting configuration information; the logical channel group LCG is configured as a logical channel group LCG supporting the enhanced delayed status reporting, or the logical channel LCH is configured as a logical channel LCH supporting the enhanced delayed status reporting, and the performing of the reporting of the delayed status reporting or the performing of the reporting of the enhanced delayed status reporting according to the remaining time and the reporting configuration information comprises: performing the reporting of the enhanced delayed status reporting according to the remaining time and the reporting configuration information.

[0038] In the embodiments of the present application, the LCG or the LCH can be configured in advance, and the LCG or the LCH can be configured to support a delayed status reporting type or an enhanced delayed status reporting type. Correspondingly, the LCG or the LCH configured to support the delayed status reporting type supports the performing of the reporting of the delayed status reporting but does not support the performing of the reporting of the enhanced delayed status reporting; and the LCG or the LCH configured to support the enhanced delayed status reporting type supports the performing of the reporting of the enhanced delayed status reporting but does not support the performing of the reporting of the delayed status reporting.

[0039] In some possible implementation manners, the method further comprises: determining, based on the reporting configuration information comprising a reporting trigger threshold corresponding to the delayed status reporting, that the logical channel group LCG is configured as a logical channel group LCG supporting the delayed status reporting, or determining that the logical channel LCH is configured as a logical channel LCH supporting the delayed status reporting; determining, based on the reporting configuration information comprising a reporting trigger threshold corresponding to the enhanced delayed status reporting and a plurality of remaining time thresholds, that the logical channel group LCG is configured as a logical channel group LCG supporting the enhanced delayed status reporting, or determining that the logical channel LCH is configured as a logical channel LCH supporting the enhanced delayed status reporting; determining, based on the reporting configuration information comprising first indication information indicating that the logical channel group LCG or the logical channel LCH supports the delayed status reporting, that the logical channel group LCG is configured as a logical channel group LCG supporting the delayed status reporting or the logical channel LCH; and determining, based on the reporting configuration information comprising second indication information indicating that the logical channel group LCG or the logical channel LCH supports the enhanced delayed status reporting, that the logical channel group LCG is configured as a logical channel group LCG supporting the enhanced delayed status reporting or the logical channel LCH.

[0040] In the embodiments of the present application, the LCG or LCH can be configured to support the delay status reporting type or the enhanced delay status reporting type in the following two ways. In this configuration, the LCG or LCH can only be configured to support only one type of status reporting, and cannot support both the delay status reporting and the enhanced delay status reporting.

[0041] The first way is to configure a threshold indication. When a reporting trigger threshold corresponding to the delay status reporting is configured, it is determined that the LCG or LCH is configured to support the delay status reporting type. When a reporting trigger threshold corresponding to the enhanced delay status reporting and a plurality of remaining time thresholds are configured, it is determined that the LCG or LCH is configured to support the enhanced delay status reporting type.

[0042] The second way is to indicate by explicit indication information. When the reporting configuration information includes first indication information indicating that the LCG or LCH supports the delay status reporting, it is determined that the LCG or LCH is configured to support the delay status reporting type. When the reporting configuration information includes second indication information indicating that the LCG or LCH supports the enhanced delay status reporting, it is determined that the LCG or LCH is configured to support the enhanced delay status reporting type.

[0043] In some possible implementation manners, the LCG is configured to support the delay status reporting and the enhanced delay status reporting, or the LCH is configured to support the delay status reporting and the enhanced delay status reporting.

[0044] In the embodiments of the present application, the LCG or LCH can also be configured to support the delay status reporting and the enhanced delay status reporting type. In this configuration, the corresponding LCG or LCH can report both the delay status reporting and the enhanced delay status reporting, providing the optional of multiple reporting modes.

[0045] In some possible implementation manners, the method further includes: if the reporting configuration information includes a reporting trigger threshold corresponding to the delay status reporting and a reporting trigger threshold corresponding to the enhanced delay status reporting and a plurality of remaining time thresholds, it is determined that the LCG is configured to support the delay status reporting and the enhanced delay status reporting, or it is determined that the LCH is configured to support the delay status reporting and the enhanced delay status reporting; or, if the reporting configuration information includes third indication information indicating that the LCG or LCH supports the delay status reporting and the enhanced delay status reporting, it is determined that the LCG is configured to support the delay status reporting and the enhanced delay status reporting, or it is determined that the LCH is configured to support the delay status reporting and the enhanced delay status reporting.

[0046] In the embodiments of the present application, the LCG or LCH can be configured to support the delay status reporting and the enhanced delay status reporting in the following two ways. In this configuration, the LCG or LCH is configured to support only two types of status reporting, which can support the delay status reporting and the enhanced delay status reporting at the same time.

[0047] The first way is to configure a threshold indication. When the LCG or LCH is configured with the reporting trigger threshold corresponding to the delay status reporting and the reporting trigger threshold corresponding to the enhanced delay status reporting and a plurality of remaining time thresholds, it can be determined that the LCG or LCH is configured to support the delay status reporting and the enhanced delay status reporting.

[0048] It should be noted that the reporting trigger threshold corresponding to the delay status reporting and the reporting trigger threshold corresponding to the enhanced delay status reporting can be the same threshold value. Further, the reporting trigger threshold corresponding to the delay status reporting can not be specifically indicated in the reporting configuration information, and the reporting trigger threshold corresponding to the delay status reporting is directly defaulted to use the reporting trigger threshold corresponding to the enhanced delay status reporting.

[0049] The second way is to indicate by explicit indication information. When the reporting configuration information includes third indication information indicating that the LCG or LCH supports the delay status reporting and the enhanced delay status reporting, it is determined that the LCG or LCH is configured to support the delay status reporting and the enhanced delay status reporting.

[0050] In some possible implementation manners, the reporting configuration information includes a reporting trigger threshold, and the reporting trigger threshold is used to trigger the reporting of the delay status reporting or the reporting of the enhanced delay status reporting.

[0051] In the embodiments of the present application, the reporting trigger threshold corresponding to the delay status reporting and the reporting trigger threshold corresponding to the enhanced delay status reporting can be the same threshold value, that is, the reporting trigger threshold, which can trigger the reporting of the delay status reporting and the reporting of the enhanced delay status reporting.

[0052] In some possible implementation manners, the to-be-transmitted data packet is not transmitted as a protocol data unit (PDU) of a medium access control (MAC) layer, the data amount of the to-be-transmitted data packet is not reported in the delay status reporting and / or the enhanced delay status reporting, and the logical channel (LCG) or the logical channel (LCH) is not performing the reporting of the delay status reporting and / or the reporting of the enhanced delay status reporting.

[0053] Wherein, the to-be-transmitted data packet is required not to be transmitted as a protocol data unit (PDU) of a medium access control (MAC) layer, on the one hand, it is guaranteed that the to-be-transmitted data packet has triggered a delay status report (DSR) but the delay status report (DSR) has not been reported to a network device, and on the other hand, since the retransmitted data packet has a relatively high priority, the retransmitted data packet is preferentially transmitted when there is an authorization, thereby ensuring that the newly transmitted data packet is transmitted.

[0054] The logical channel group (LCG) or the logical channel (LCH) is not in the execution of the reporting of the delay status report and / or the reporting of the enhanced delay status report, which means that there is no delay status report and / or enhanced delay status report in a pending state, that is, there is no delay status report and / or enhanced delay status report waiting to be sent but not yet sent, thereby avoiding repeated reporting.

[0055] The data amount of the to-be-transmitted data packet is not reported in the previous delay status report and / or enhanced delay status report, which can avoid repeated sending of the report.

[0056] It can be understood that a person skilled in the art can adjust and configure the related limitation conditions based on actual business needs, and the embodiments of the present application are not limited.

[0057] In some possible implementation manners, the reporting of the delay status report or the reporting of the enhanced delay status report is performed based on a first reporting condition or a second reporting condition, wherein the first reporting condition comprises at least one of the following conditions: each logical channel group (LCG) or logical channel (LCH) includes only one set of delay information; a remaining time of the set of delay information included in the LCG or LCH is less than or equal to a reporting trigger threshold; a data packet of the set of delay information is not transmitted as a protocol data unit (PDU) of a medium access control (MAC) layer; an amount of data of the data packet of the set of delay information is not reported in the delay status report; a first object is configured with information indicating that the delay status report is used; the first object is not configured with information indicating that the enhanced delay status report is used; and a target resource is determined to be used for carrying the delay status report based on a logical channel priority (LCP) result. The second reporting condition comprises at least one of the following conditions: at least two sets of delay information are included in at least one LCG or LCH; a remaining time of at least one set of delay information included in the at least one LCG or LCH is less than or equal to the reporting trigger threshold; a data packet of the at least two sets of delay information is not transmitted as a PDU of a MAC layer; an amount of data of the data packet of the at least two sets of delay information is not reported in the enhanced delay status report; the first object is configured with information indicating that the enhanced delay status report is used; and the target resource is determined to be used for carrying the enhanced delay status report based on an LCP result. The first object comprises an LCG, an LCH, or a MAC entity.

[0058] In the embodiments of the present application, when the LCG or LCH is configured to support the type of the delay status report and the enhanced delay status report, the terminal device can determine whether to actually perform the reporting of the delay status report or the reporting of the enhanced delay status report based on the judgment of the reporting condition, for example, determine the delay reporting type according to the number of sets of delay information, or for example, determine the delay reporting type according to the configuration information of the first object comprising the LCG or LCH or the MAC entity. In the case of satisfying the first reporting condition, the reporting of the delay status report is performed; and in the case of satisfying the second reporting condition, the reporting of the enhanced delay status report is performed.

[0059] In some possible implementation manners, the reporting of the delay status report or the reporting of the enhanced delay status report is performed based on a third reporting condition for a logical channel group (LCG) or a logical channel (LCH), and based on a fourth reporting condition for the LCG or the LCH, wherein the third reporting condition includes at least one of the following conditions: the LCG or the LCH includes only one set of delay information; a remaining time of the set of delay information included in the LCG or the LCH is less than or equal to the reporting trigger threshold; a first object is configured with information indicating that the delay status report is used; the first object is not configured with information indicating that the enhanced delay status report is used; and a target resource is determined to be used to carry the delay status report based on a logical channel priority (LCP) result; and the fourth reporting condition includes at least one of the following conditions: the LCG or the LCH includes at least two sets of delay information; a remaining time of at least one of the two sets of delay information included in the LCG or the LCH is less than or equal to the reporting trigger threshold; the first object is configured with information indicating that the enhanced delay status report is used; the target resource is determined to be used to carry the enhanced delay status report based on the LCP result; and the first object includes the LCG, the LCH, or a MAC entity.

In the case that the first trigger condition or the second trigger condition is met, the enhanced delay status reporting is performed; in the case that the first trigger condition and the second trigger condition are not met, and the third trigger condition is met, the delay status reporting is performed.

[0071] In the embodiments of the present application, when each of the plurality of LCGs or each of the plurality of LCHs only has one set of delay information, and the delay information satisfies the reporting trigger threshold of the delay status reporting, i.e., the remaining time in the delay information is less than the reporting trigger threshold of the delay status reporting, the reporting of the enhanced delay status reporting of the plurality of LCGs or LCHs can be cancelled, and the reporting of the delay status reporting of the plurality of LCGs or LCHs is performed.

[0072] In some possible implementation manners, the method further includes: based on a logical channel group (LCG) or a logical channel (LCH) only having one set of delay information, cancelling the reporting of the enhanced delay status reporting of the logical channel group (LCG) or the logical channel (LCH).

[0107] It should be noted that the communication system described in the embodiments of the present application is for more clearly illustrating the technical solutions of the embodiments of the present application, and does not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those skilled in the art can know that, with the evolution of network architecture and the appearance of new business scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0108] In order to make the technical solutions of the present application clearer and easier to understand, the method of delayed state reporting provided by the embodiments of the present application will be introduced below in conjunction with the drawings.

[0109] The existing reporting mechanism of the delayed status report (DSR) is that the terminal device provides the network device with the delay state information of a logical channel group (LCG) or a logical channel (LCH), and the delay state information includes a remaining time and a data amount of delay critical data, and the data amount of delay critical data includes the data amount of a packet data convergence protocol (PDCP) layer and a radio link control (RLC) layer. The remaining time is the minimum remaining value of the PDCP discard timer discardTimers of the buffered data packets in the LCG or LCH, and these buffered data packets have not been transmitted in the MAC PDU.

[0110] Among them, the PDCP layer calculates the data amount of delay critical data considering the following contents:

[0111] 1. Delay critical SDU which has not been assembled into a PDU;

[0112] 2. PDU including delay critical SDU which has not been submitted to lower layer;

[0113] 3. PDU controlled by PDCP layer;

[0114] 4. PDCP layer SDU which needs to be retransmitted;

[0115] 5. PDCP layer PDU which needs to be retransmitted.

[0116] Among them, the RLC layer calculates the data amount of delay critical data considering the following contents:

[0117] 1. Delay critical SDU and delay critical SDU segment which has not been included in a PDU;

[0118] 2. PDU including delay critical SDU or delay critical SDU segment which is still waiting for initial transmission;

[0119] 3. PDU waiting for retransmission.

[0120] In addition, if the status PDU is triggered (the prohibit timer of the status PDU is not running or expires), the terminal device estimates the size of the status PDU and considers the size in the delay critical data amount.

[0121] In the reporting mechanism of the existing DSR, the network side will configure a remaining time threshold remainingTimeThreshold for triggering the DSR reporting of a logical channel group LCG. If a DSR is configured for the LCG, the MAC entity performs the following operations on each logical channel LCH of the LCG: when the minimum remaining time in the discard timer of all PDCP data packets buffered in the LCH is less than remainingTimeThreshold, and the data packet has not been transmitted in the MAC PDU and has not been reported as data amount in the DSR, and the LCH does not have a DSR being processed; a DSR is triggered for the LCH.

[0122] If the LCH has a DSR being processed, the MAC entity performs the following operations:

[0123] 1. If there is uplink shared channel (UL-SCH) resource available for new transmission resource, and the UL-SCH resource can include DSR according to logical channel priority (LCP) indication, indicate multiplexing and assembly procedure to generate DSR MAC CE.

[0124] Rel-18 XR reports a minimum set of remaining time and related buffer data volume for one LCG, and the current meeting conclusion discusses reporting multiple sets of remaining time and buffer data volume for one LCG. For example, one set of delay information is reported for a remaining time less than 2 ms, and one set of delay information is reported for a remaining time greater than 2 ms and less than 4 ms, so that the network can determine how many resources to schedule according to the scheduled time. The EDSR reporting mechanism can configure a reporting trigger threshold for one EDSR, for example, using the minimum threshold configured by the network as the trigger threshold, which can prevent the problem of frequent triggering of EDSR. Since the format of EDSR is not determined, it may carry the data volume of non-delay critical data in DSR, and may include importance information. In this case, one LCG can distinguish between reporting delay critical data volume and non-delay critical data volume.

[0125] However, there is no clear distinction between the two delay state reporting mechanisms in actual use. The present application proposes a delay state reporting method that distinguishes between DSR and EDSR mechanisms in use.

[0126] Referring to FIG. 2, a flowchart of a delay state reporting method is shown, which is applied to a terminal device, and the method comprises:

[0127] Step 201: Perform enhanced delayed status report (EDSR) reporting according to the remaining time and reporting configuration information.

[0128] Wherein, the remaining time is the remaining time of the data packet to be transmitted in the logical channel group (LCG) or logical channel (LCH), and the enhanced delayed status report (EDSR) includes at least one set of delay information of the logical channel group (LCG) or logical channel (LCH), and the delay information includes remaining time information and / or data volume information.

[0129] It should be noted that the residual time involved in the embodiments of the present application can also be the residual time of a protocol data unit set (PUD set). Correspondingly, the enhanced delay status report (EDSR) can include at least one group of delay information of the PUD set. Thus, the residual time of the data packet to be transmitted in the logical channel group (LCG) or the logical channel (LCH) in the embodiments of the present application can be replaced by the residual time of the data packet to be transmitted in the logical channel group (LCG) or the logical channel (LCH) or the residual time of the PUD set, and the enhanced delay status report (EDSR) including at least one group of delay information of the logical channel group (LCG) or the logical channel (LCH) can be replaced by the enhanced delay status report (EDSR) including at least one group of delay information of the logical channel group (LCG) or the logical channel (LCH) or the PUD set.

[0130] In the embodiments of the present application, the residual time of the data packet to be transmitted is not limited, and the residual time should be a value greater than zero. When the LCG or the LCH includes more than one data packet to be transmitted, the residual time can be the minimum value of the residual time of all the data packets to be transmitted in the LCG or the LCH.

[0131] For example, the residual time can be the residual time of the discard timer of the data packet to be transmitted, such as the residual time of the discard timer of the data packet buffered in the packet data convergence protocol (PDCP) layer of the logical channel (LCH); or the residual time of the waiting timer of the data packet to be transmitted.

[0132] The data amount information refers to the data amount size corresponding to the delay critical data packet.

[0133] It should be noted that the reporting of the enhanced delay status report (EDSR) in the embodiments of the present application, that is, the reporting process of the EDSR can include: the triggering process of the EDSR, the generation and reporting process of the EDSR, and the cancellation process of the EDSR. In the embodiments of the present application, a use mechanism of the enhanced delay status report is provided from the triggering condition of the enhanced delay status report, and the terminal device can perform the reporting of the enhanced delay status report (EDSR) according to the residual time of the data packet to be transmitted and the reporting configuration information.

[0134] Optionally, the reporting configuration information includes a reporting trigger threshold.

[0135] The reporting trigger threshold is used to trigger the reporting of the enhanced delay status report, and the enhanced delay status report (EDSR) includes at least one group of delay information with a residual time less than or equal to the reporting trigger threshold.

[0136] Specifically, the reporting configuration information can include a reporting trigger threshold for enhanced delay status reporting, and the reporting trigger threshold is used to trigger the reporting of the enhanced delay status reporting. When the remaining time of the data packet to be transmitted is less than or equal to the reporting trigger threshold, the reporting of the enhanced delay status reporting is triggered, and the enhanced delay status reporting should include at least one group of delay information with a remaining time less than or equal to the reporting trigger threshold.

[0137] Optionally, the reporting configuration information further includes a plurality of remaining time thresholds.

[0138] The plurality of remaining time thresholds are used to configure the reporting trigger threshold, and the reporting trigger threshold can be configured as a minimum value or a maximum value of the plurality of remaining time thresholds, or a specified remaining time threshold value in the plurality of remaining time thresholds.

[0139] Specifically, a plurality of remaining time thresholds can be configured for the enhanced delay status reporting in the embodiments of the present application. The plurality of remaining time thresholds can be used to configure the reporting trigger threshold for the enhanced delay status reporting. The reporting trigger threshold can be configured as any threshold value in the plurality of remaining time thresholds, such as a maximum value, a minimum value, or a specified threshold value. The specified threshold value is the reporting trigger threshold configured by the network side in the plurality of remaining time thresholds. If the maximum value, it means that the network needs to schedule data packets less than all the remaining time thresholds. If the minimum value, it means that the network needs to schedule data packets less than the minimum value of all the remaining time thresholds. Other threshold information is used for further scheduling by the network side. If it is a specified threshold value, it provides more flexibility for the network side to schedule, so that the network side can make flexible scheduling according to the existing network environment. The skilled person can adaptively configure the reporting trigger threshold according to the actual business needs.

[0140] After the enhanced delay status reporting is triggered, the resource assembly and the generation of the enhanced delay status reporting are waited for. After a period of time, there can be no delay information less than the trigger threshold, but there can be delay information less than the remaining time threshold. In this case, the enhanced delay status reporting can not need to be reported because there is no delay information less than the reporting trigger threshold, and the urgency of such delay information is generally not required to be reported. Therefore, the enhanced delay status reporting to be reported should include at least one group of delay information with a remaining time less than or equal to the reporting trigger threshold.

[0141] Optionally, it can be required that each LCG should include at least one group of delay information with a remaining time less than or equal to the reporting trigger threshold, or it can be required that the EDSR includes at least one group of delay information with a remaining time less than or equal to the reporting trigger threshold.

[0142] Exemplarily, the reporting trigger threshold is 3 ms, the multiple residual time thresholds are 5 ms, 8 ms and 10 ms, if there is no data packet to be transmitted with a residual time less than 3 ms, but there is data packet to be transmitted with a residual time in the range of 5 ms to 10 ms, in this case, the reporting of the EDSR does not need to be performed.

[0143] Optionally, the EDSR includes a set of delay information, and the delay information has a residual time less than or equal to the reporting trigger threshold, and the reporting of the enhanced delay status report is performed.

[0144] Optionally, the EDSR does not need to include delay information with a residual time less than or equal to the reporting trigger threshold.

[0145] Exemplarily, the reporting trigger threshold is 3 ms, the multiple residual time thresholds are 5 ms, 8 ms and 10 ms, if there is no data packet to be transmitted with a residual time less than 3 ms, but there is data packet to be transmitted with a residual time in the range of 5 ms to 10 ms, in this case, the reporting of the EDSR needs to be performed.

[0146] Optionally, whether the terminal device performs the reporting of the EDSR can be configured by the network side through indication information.

[0147] Optionally, the network side can directly indicate, through a MAC CE, whether the terminal device performs the reporting of the EDSR, and exemplarily, the network side indicates that the terminal device should include at least one set of delay information with a residual time less than or equal to the reporting trigger threshold in the EDSR.

[0148] Optionally, the reporting configuration information further includes indication information of reporting the EDSR.

[0149] The method for reporting a delay status provided in the embodiments of the present application can further include: performing the reporting of the EDSR based on the reporting trigger threshold and the indication information of reporting the EDSR.

[0150] In the EDSR, the at least one set of delay information reported is reported based on the reporting trigger threshold and a time interval; for example, the reporting trigger threshold is 10 ms, and the time interval is 2 ms, and then the EDSR includes delay information corresponding to residual time intervals of 0-2 ms, 2 ms-4 ms, 4 ms-6 ms, 6 ms-8 ms and 8 ms-10 ms.

[0151] It can be understood that, in the case where the indication information of reporting the EDSR is not configured, the terminal device performs the reporting of the DSR, and the DSR includes a set of delay information.

[0152] Optionally, the data packets to be transmitted include at least one of the following data packets: a data packet with a remaining time less than or equal to the reporting trigger threshold; a data packet belonging to a protocol data unit set, and the protocol data unit set including at least one data packet with a remaining time less than or equal to the reporting trigger threshold; a data packet with a remaining time less than or equal to a minimum value or a maximum value of a plurality of remaining time thresholds; a data packet belonging to a protocol data unit set, and the protocol data unit set including at least one data packet with a remaining time less than or equal to a minimum value or a maximum value of a plurality of remaining time thresholds; a data packet with a remaining time less than or equal to a specified remaining time threshold value of a plurality of remaining time thresholds; and a data packet belonging to a protocol data unit set, and the protocol data unit set including at least one data packet with a remaining time less than or equal to a specified remaining time threshold value of a plurality of remaining time thresholds.

[0153] The data amount information included in the delay information specifically refers to data amount information of data packets corresponding to the plurality of remaining time thresholds. For example, the plurality of remaining time thresholds include 10 ms and 5 ms; the data amount information can include data amount information of data packet 1 with a remaining time less than or equal to 10 ms, and data amount information of data packet 2 with a remaining time less than or equal to 5 ms; or the data amount information can be data amount information of data packet 3 with a remaining time less than or equal to 10 ms and greater than 5 ms, and data amount information of data packet 4 with a remaining time less than or equal to 5 ms and greater than 0 ms.

[0154] For example, the plurality of remaining thresholds include 10 ms and 5 ms, wherein the reporting trigger threshold is 5 ms, data packet 1 includes delay critical data packets with a remaining time less than or equal to 5 ms and data packets with a remaining time greater than 5 ms and less than or equal to 10 ms; data packet 2 includes delay critical data packets with a remaining time less than or equal to 5 ms; data packet 3 includes data packets with a remaining time greater than 5 ms and less than or equal to 10 ms; and data packet 4 includes delay critical data packets with a remaining time less than or equal to 5 ms. The data packets with a remaining time less than or equal to 5 ms can be referred to as delay critical data packets.

[0155] In the embodiments of the present application, the remaining time less than or equal to the threshold value can be understood as the case that the remaining time reaches less than or equal to the threshold value.

[0156] The PDCP layer calculates the data amount of the delay information, including the following contents:

[0157] 1. Data packet 1 or data packet 2 or data packet 3 or data packet 4 that has not yet formed a protocol data unit;

[0158] 2. PDU including data packet 1 or data packet 2 or data packet 3 or data packet 4 that has not yet been submitted to the underlying layer;

[0159] and / or

[0160] 3. PDCP layer controlled PDU;

[0161] 4. PDCP layer SDU requiring retransmission;

[0162] 5. PDCP layer PDU requiring retransmission.

[0163] Wherein, the data volume considered by the RLC layer in calculating the delay information includes:

[0164] 1. Data packet 1 or data packet 2 or data packet 3 or data packet 4, and data packet 1 segment or data packet 2 segment or data packet 3 segment or data packet 4 segment, which have not been included in the PDU;

[0165] 2. PDU including data packet 1 or data packet 2 or data packet 3 or data packet 4, or data packet 1 segment or data packet 2 segment or data packet 3 segment or data packet 4 segment, which are still waiting for initial transmission;

[0166] and / or

[0167] 3. PDU waiting for retransmission.

[0168] Wherein, the data volume included in the delay information includes the data volume corresponding to the delay critical data packet, and the delay critical data packet can include the data packet with the remaining time less than or equal to the reporting trigger threshold. When reporting the delay status report, the data volume of the delay critical data packet is reported.

[0169] In addition, when the protocol data unit (PUD) set is discarded based on the protocol data unit set discard configuration, when at least one data packet in the protocol data unit set meets the condition that the remaining time is less than the configured reporting trigger threshold, all data packets in the protocol data unit set belong to delay critical data packets. Since all data packets in the protocol data unit set will be discarded when one data packet in the protocol data unit set is discarded, when reporting the delay information, when one data packet in the protocol data unit set meets the reporting trigger threshold, all data packets in the protocol data unit set should be considered as delay critical data packets and reported together.

[0170] Optionally, the to-be-transmitted data packet is not transmitted as a protocol data unit (PDU) of a medium access control (MAC) layer, a logical channel group (LCG) or a logical channel (LCH) does not perform reporting of the enhanced delay status report, the data volume of the to-be-transmitted data packet is not reported in the enhanced delay status report, or the data volume of the to-be-transmitted data packet is not reported in the delay status report and the enhanced delay status report.

[0171] Wherein, the to-be-transmitted data packet is required not to be transmitted as a protocol data unit (PDU) of a medium access control (MAC) layer, on one hand, it is guaranteed that the to-be-transmitted data packet has not been reported to a network device even if a delay status report (DSR) is triggered, and on the other hand, the retransmitted data packet has a higher priority and is transmitted preferentially when there is an authorization, thereby ensuring that the newly transmitted data packet is transmitted.

[0172] The LCG or LCH not performing the reporting of the enhanced delay status report means that there is no pending enhanced delay status report, that is, there is no enhanced delay status report waiting to be sent but not yet sent, thereby avoiding repeated reporting.

[0173] It should be noted that if the embodiment of the present application takes a PDU set as the granularity of delay information reporting, the PDU set not performing the reporting of the enhanced delay status report should be considered accordingly, wherein, taking the PDU set as the granularity can be based on the characteristics of the PDU set to consider the granularity, so as to avoid the problem of repeated reporting.

[0174] The data amount of the to-be-transmitted data packet is not reported in the enhanced delay status report, or the data amount of the to-be-transmitted data packet is not reported in the delay status report and the enhanced delay status report, which can also avoid repeated sending of delay information, and since the delay information provided in the delay status report is not as rich as that in the enhanced delay status report, the reporting in the delay status report is optional, that is, even if it is reported in the delay status report, the enhanced delay status report providing more rich delay information can still be reported.

[0175] Optionally, the method for reporting a delay status provided by the embodiment of the present application can further include: canceling the reporting of the enhanced delay status report based on a first canceling condition; wherein the first canceling condition includes at least one of the following conditions: the first data packet has been discarded or the second data packet has been discarded; the first data packet or the second data packet has been transmitted as a PDU of a MAC layer; the EDSR including the first data packet or the second data packet has been reported; the LCH or LCG associated with the first data packet or the second data packet triggers the reporting of the EDSR, and the first data packet and the second data packet have not been transmitted in a MAC PDU; the remaining time of the first data packet is less than or equal to a reporting trigger threshold; and the remaining time of the second data packet is less than or equal to a maximum value of a plurality of remaining time thresholds.

[0176] Canceling the reporting of the enhanced delay status report according to the discarding of the second data packet can be referred to as that the data packet associated with the delay status required to be reported in the enhanced delay status report has been discarded.

[0177] In a case where the first cancellation condition is met, the reporting of the enhanced delay status report can be cancelled. For example, the relevant data packet has been discarded, or the relevant data packet has been transmitted as a MAC layer PDU, and accordingly, there is no meaning to report the to-be-transmitted data packet, where the relevant data packet refers to all relevant data packets. At this time, the reporting of the enhanced delay status report can be cancelled, so as to avoid meaningless delay information reporting and resource waste.

[0178] It should be noted that, in a case where a PDU set is used as a granularity of delay information reporting, the first data packet or the second data packet associated with the LCH or the LCG triggers the reporting of the EDSR in the first cancellation condition, and the first data packet and the second data packet are not transmitted in the MAC PDU, which can be replaced with the PDU set associated with the first data packet or the second data packet triggering the reporting of the EDSR, and the first data packet and the second data packet are not transmitted in the MAC PDU. The PDU set can be considered as a granularity based on a characteristic of the PDU set.

[0179] Optionally, the method for reporting a delay status provided in the embodiments of the present application can further include: if the reporting of the delay status is being performed, generating an enhanced delay status report based on a first generation condition; and triggering a scheduling request SR based on a first scheduling condition, where the scheduling request SR is used to request an uplink shared channel UL-SCH resource for transmitting the enhanced delay status report.

[0180] The first generation condition includes that the uplink shared channel UL-SCH resource includes a target resource for new transmission, and the target resource is determined to be used to carry the enhanced delay status report based on a logical channel priority LCP result.

[0181] The first scheduling condition includes at least one of the following conditions: there is no scheduling request of the enhanced delay status report and / or the delay status report being processed; and the scheduling request SR is the same as a logical channel or a logical channel group LCG corresponding to the triggering of the delay status report and / or the enhanced delay status report.

[0182] The mechanism for triggering the EDSR can be triggered in a granularity of a logical channel group LCG, a logical channel LCH, or a PDU set, where the PDU set can be considered as a granularity based on a characteristic of the PDU set.

[0183] In a case where the first generation condition is met, the terminal device can be instructed to generate an enhanced delay status report, for example: a logical channel group (LCG) or a logical channel (LCH) is processing a delay status report (DSR), uplink shared channel (UL-SCH) resources include target resources for new transmission, and the target resources can carry the enhanced delay status report based on a logical channel prioritization (LCP) result. In this case, a multiplexing and assembling process can be triggered to generate a media access control (MAC) control element (CE) corresponding to the enhanced delay status report (EDSR).

[0184] In addition, in a case where the first scheduling condition is met, a scheduling request (SR) can be triggered, for example: a logical channel group (LCG) or a logical channel (LCH) does not exist that is processing a delay status report (DSR) or an enhanced delay status report (EDSR), and a scheduling request (SR) corresponding to a logical channel (LCH) triggering a delay status report and / or an enhanced delay status report is the same logical channel (LCH). In this case, the scheduling request (SR) for the delay status report and the scheduling request (SR) for the enhanced delay status report have the same configuration, which is based on the configuration of the logical channel or the logical channel group.

[0185] It should be noted that if the PDU set is used as the granularity of the delay information reporting in the embodiments of the present application, the LCG or LCH in the above-mentioned first generation condition and the first scheduling condition can be replaced by the PDU set. For example, the first scheduling condition that the logical channel group (LCG) or the logical channel (LCH) does not exist that is processing a delay status report (DSR) or an enhanced delay status report (EDSR) can be replaced by the PDU set that does not exist that is processing a delay status report (DSR) or an enhanced delay status report (EDSR). In this case, the PDU set is used as the granularity to consider the characteristics based on the PDU set.

[0186] In some possible implementation manners, the reporting configuration information is configured through radio resource control (RRC) signaling.

[0187] In some possible implementation manners, the reporting configuration information is configured through a MAC CE.

[0188] Optionally, the reporting configuration information can be configured by radio resource control (RRC) signaling and MAC CE. For example, the reporting trigger threshold is configured by RRC signaling, and the EDSR indication is configured by MAC CE. After receiving the indication of the MAC CE, the terminal device activates the reporting process of the EDSR.

[0189] In the embodiments of the present application, the reporting configuration information can be configured by a network device through radio resource control (RRC) signaling.

[0190] Next, another flowchart of a method for reporting a delay state is shown in FIG. 3. The method is applied to a terminal device, and the method includes the following steps:

[0191] Step 301: According to the remaining time and the reporting configuration information, performing reporting of a delayed status report (DSR) or performing reporting of an enhanced delayed status report (EDSR).

[0192] In the embodiments of the present application, the remaining time can be the remaining time of a protocol data unit set (PUD set). Correspondingly, the delayed status report DSR can include a set of delay information of the PUD set, and the enhanced delayed status report EDSR can include at least a set of delay information of the PUD set. Therefore, the remaining time of the logical channel group LCG or the logical channel LCH in the embodiments of the present application can be replaced by the remaining time of the logical channel group LCG or the logical channel LCH or the remaining time of the PUD set, and the delayed status report including a set of delay information of the logical channel group LCG or the logical channel LCH can be replaced by the delayed status report including a set of delay information of the logical channel group LCG or the logical channel LCH or the PUD set, wherein the granularity of the PUD set can be considered based on the characteristics of the PUD set.

[0193] In the embodiments of the present application, the remaining time can be the remaining time of a protocol data unit set (PUD set). Correspondingly, the delayed status report DSR can include a set of delay information of the PUD set, and the enhanced delayed status report EDSR can include at least a set of delay information of the PUD set. Therefore, the remaining time of the logical channel group LCG or the logical channel LCH in the embodiments of the present application can be replaced by the remaining time of the logical channel group LCG or the logical channel LCH or the remaining time of the PUD set, and the delayed status report including a set of delay information of the logical channel group LCG or the logical channel LCH can be replaced by the delayed status report including a set of delay information of the logical channel group LCG or the logical channel LCH or the PUD set, wherein the granularity of the PUD set can be considered based on the characteristics of the PUD set.

[0194] The remaining time of the to-be-transmitted data packet is not limited in the embodiments of the present application, and should be a value greater than zero. When more than one to-be-transmitted data packet is included in the LCG or LCH, the remaining time can be the minimum value of the remaining time of all to-be-transmitted data packets in the LCG or LCH.

[0195] For example, the remaining time can be the remaining time of the discard timer discardTimer of the to-be-transmitted data packet, such as the remaining time of the discard timer discardTimer of the data packet buffered in the Packet Data Convergence Protocol (PDCP) layer of the logical channel LCH; or the remaining time of the waiting timer of the to-be-transmitted data packet.

[0196] The data amount information refers to the data amount size corresponding to the delay-critical data packet.

[0197] It should be noted that the reporting of the enhanced delay status report EDSR in the embodiments of the present application, i.e., the reporting process of the EDSR, can include the triggering process of the EDSR, the generation and reporting process of the EDSR, and the cancellation process of the EDSR. The reporting of the delay status report DSR in the embodiments of the present application, i.e., the reporting process of the DSR, can include the triggering process of the DSR, the generation and reporting process of the DSR, and the cancellation process of the DSR. The embodiments of the present application provide a delay status reporting method that can report both the DSR and the EDSR from the perspective of combining the delay status report DSR and the enhanced delay status report EDSR, and the terminal device can perform the reporting of the delay status report DSR or the reporting of the enhanced delay status report EDSR according to the remaining time of the to-be-transmitted data packet and the reporting configuration information.

[0198] Optionally, the logical channel group LCG is configured as a logical channel group LCG supporting the delay status report, or the logical channel LCH is configured as a logical channel LCH supporting the delay status report, and the reporting of the delay status report or the reporting of the enhanced delay status report is performed according to the remaining time and the reporting configuration information, including: performing the reporting of the delay status report according to the remaining time and the reporting configuration information.

[0199] The logical channel group LCG is configured as a logical channel group LCG supporting the enhanced delay status report, or the logical channel LCH is configured as a logical channel LCH supporting the enhanced delay status report, and the reporting of the delay status report or the reporting of the enhanced delay status report is performed according to the remaining time and the reporting configuration information, including: performing the reporting of the enhanced delay status report according to the remaining time and the reporting configuration information.

[0200] In the embodiments of the present application, the LCG or LCH can be configured in advance, and the LCG or LCH can be configured to support the delay status reporting type or the enhanced delay status reporting type. Correspondingly, the LCG or LCH configured to support the delay status reporting type can perform the reporting of the delay status report, and the LCG or LCH configured to support the enhanced delay status reporting type can perform the reporting of the enhanced delay status report. In the above method, optionally, the LCG or LCH configured to support the enhanced delay status reporting type can perform the reporting of the enhanced delay status report but cannot perform the reporting of the delay status report; and the LCG or LCH configured to support the delay status reporting type can perform the reporting of the delay status report but cannot perform the reporting of the enhanced delay status report. Optionally, the reporting method of the delay status provided by the embodiments of the present application can further include: determining that the LCG is configured to support the LCG of the delay status report based on the reporting configuration information including the reporting trigger threshold corresponding to the delay status report, or determining that the LCH is configured to support the LCH of the delay status report; determining that the LCG is configured to support the LCG of the enhanced delay status report based on the reporting configuration information including the reporting trigger threshold corresponding to the enhanced delay status report and the plurality of remaining time thresholds, or determining that the LCH is configured to support the LCH of the enhanced delay status report; determining that the LCG is configured to support the LCG of the delay status report based on the reporting configuration information including the first indication information indicating that the LCG or the LCH supports the delay status report, or determining that the LCH is configured to support the LCH of the delay status report; and determining that the LCG is configured to support the LCG of the enhanced delay status report based on the reporting configuration information including the second indication information indicating that the LCG or the LCH supports the enhanced delay status report, or determining that the LCH is configured to support the LCH of the enhanced delay status report.

[0201] It should be noted that if the embodiment of the present application reports the delay information with the granularity of the PDU set, the PDU set can be pre-configured, and the PDU set can be configured to support the delay status reporting type or the enhanced delay status reporting type. Optionally, the type of delay information reporting supported by the PDU set can be determined based on the priority of the PDU set. For example, the PDU set is pre-configured with three priorities, including priority 1, priority 2, and priority 3. The PDU set corresponding to the priority 1 is configured to support the enhanced delay status reporting type, and the PDU set corresponding to the priority 2 and the priority 3 is configured to support the delay status reporting type. The priority 1 is ranked higher than the priority 2 and the priority 3. For example, the PDU set is pre-configured with two importance levels, a high importance level and a low importance level. The type of delay information reporting supported by the PDU set can be configured based on the importance level of the PDU set.

[0202] Specifically, in the embodiment of the present application, the LCG or the LCH can be configured to support the delay status reporting type or the enhanced delay status reporting type in the following two ways. In this configuration, the LCG or the LCH can only be configured to support one type of status reporting, and cannot support both the delay status reporting and the enhanced delay status reporting.

[0203] Method one: through configuration threshold indication. When the reporting trigger threshold corresponding to the delay status reporting is configured, it is determined that the LCG or the LCH is configured to support the delay status reporting type; when the reporting trigger threshold corresponding to the enhanced delay status reporting and the plurality of residual time thresholds are configured, it is determined that the LCG or the LCH is configured to support the enhanced delay status reporting type.

[0204] Method two: indicated by explicit indication information. When the reporting configuration information includes first indication information indicating that the LCG or the LCH supports the delay status reporting, it is determined that the LCG or the LCH is configured to support the delay status reporting type; when the reporting configuration information includes second indication information indicating that the LCG or the LCH supports the enhanced delay status reporting, it is determined that the LCG or the LCH is configured to support the enhanced delay status reporting type.

[0205] Optionally, the logical channel group LCG is configured to support the delay status reporting and the enhanced delay status reporting, or the logical channel LCH is configured to support the delay status reporting and the enhanced delay status reporting.

[0206] In the embodiments of the present application, the LCG or LCH can also be configured to support delay status reporting and the type of enhanced delay status reporting. In this configuration, the corresponding LCG or LCH can report delay status reporting or enhanced delay status reporting, providing the optional reporting mode.

[0207] Optionally, the delay status reporting method provided by the embodiments of the present application can further include: determining a logical channel group LCG configured to support delay status reporting and enhanced delay status reporting of the logical channel group LCG, or determining a logical channel LCH configured to support delay status reporting and enhanced delay status reporting of the logical channel LCH, based on the reporting configuration information including the reporting trigger threshold corresponding to the delay status reporting and the reporting trigger threshold corresponding to the enhanced delay status reporting and the plurality of residual time thresholds; or determining a logical channel group LCG configured to support delay status reporting and enhanced delay status reporting of the logical channel group LCG, or determining a logical channel LCH configured to support delay status reporting and enhanced delay status reporting of the logical channel LCH, based on the reporting configuration information including the third indication information indicating that the logical channel group LCG or the logical channel LCH supports delay status reporting and enhanced delay status reporting.

[0208] In the embodiments of the present application, the LCG or LCH can be configured to support delay status reporting and the type of enhanced delay status reporting in the following two ways. In this configuration, the LCG or LCH is configured to support only two types of status reporting, which can support delay status reporting and enhanced delay status reporting at the same time.

[0209] Method one: by configuring threshold indication. When the LCG or LCH is configured with the reporting trigger threshold corresponding to the delay status reporting and the reporting trigger threshold corresponding to the enhanced delay status reporting and the plurality of residual time thresholds, it can be determined that the LCG or LCH is configured to support delay status reporting and the type of enhanced delay status reporting.

[0210] It should be noted that the reporting trigger threshold corresponding to the delay status reporting and the reporting trigger threshold corresponding to the enhanced delay status reporting can be the same threshold value. Further, the reporting configuration information can not specifically indicate the reporting trigger threshold corresponding to the delay status reporting, and the reporting trigger threshold corresponding to the delay status reporting can directly use the reporting trigger threshold corresponding to the enhanced delay status reporting by default.

[0211] Method two: indicated by explicit indication information. When the reporting configuration information includes the third indication information indicating that the LCG or LCH supports delay status reporting and enhanced delay status reporting, it is determined that the LCG or LCH is configured to support delay status reporting and the type of enhanced delay status reporting.

[0212] Optionally, the reporting configuration information comprises a reporting trigger threshold.

[0213] The reporting trigger threshold is used to trigger reporting of the delay status report or reporting of the enhanced delay status report. Triggering reporting of the delay status report or reporting of the enhanced delay status report can be collectively referred to as triggering reporting of the delay status report. In embodiments of the present application, the reporting trigger threshold corresponding to the delay status report and the reporting trigger threshold corresponding to the enhanced delay status report can be the same threshold value, i.e. the reporting trigger threshold, which can trigger reporting of the delay status report and reporting of the enhanced delay status report. Reporting of the delay status report or reporting of the enhanced delay status report is triggered based on the remaining time of the data packet to be transmitted being less than or equal to the reporting trigger threshold.

[0214] Optionally, the data packet to be transmitted is not transmitted as a protocol data unit (PDU) of a medium access control (MAC) layer, the data volume of the data packet to be transmitted is not reported in the delay status report and / or the enhanced delay status report, and the logical channel group (LCG) or the logical channel (LCH) is not reported in the reporting of the delay status report and / or the reporting of the enhanced delay status report.

[0215] The requirement that the data packet to be transmitted is not transmitted as a PDU of a MAC layer is to ensure that the data packet to be transmitted is not reported to a network device even if a delay status report is triggered, and to ensure that a data packet to be retransmitted is transmitted in priority when there is an authorization.

[0216] The LCG or the LCH not being reported in the reporting of the delay status report and / or the reporting of the enhanced delay status report means that there is no delay status report and / or enhanced delay status report in a pending state, i.e. there is no delay status report and / or enhanced delay status report that is waiting to be sent but has not yet been sent, thereby avoiding repeated reporting of delay information. It should be noted that if the PDU set is used as the granularity of reporting delay information in embodiments of the present application, the PDU set should be considered not to be reported in the reporting of the enhanced delay status report to avoid repeated reporting. The granularity based on the characteristics of the PDU set can be considered.

[0217] The data volume of the data packet to be transmitted is not reported in the previous delay status report and / or the enhanced delay status report, thereby avoiding repeated sending of delay information.

[0218] Optionally, the reporting of the delay status report or the reporting of the enhanced delay status report performed in the step 301 comprises: performing the reporting of the delay status report based on a first reporting condition; performing the reporting of the enhanced delay status report based on a second reporting condition.

[0219] The first reporting condition comprises at least one of the following conditions: each logical channel group (LCG) or logical channel (LCH) includes only one set of delay information; a remaining time of the one set of delay information included in the LCG or LCH is less than or equal to a reporting trigger threshold; a data packet of the one set of delay information is not transmitted as a protocol data unit (PDU) of a medium access control (MAC) layer; a data amount of the data packet of the one set of delay information is not reported in the delay status report; a first object is configured with information indicating that the delay status report is used; the first object is not configured with information indicating that the enhanced delay status report is used; and a target resource is determined to be used for carrying the delay status report based on a logical channel priority (LCP) result.

[0220] The second reporting condition comprises at least one of the following conditions: at least two sets of delay information are included in at least one LCG or LCH; a remaining time of at least one set of delay information included in the at least two sets of delay information is less than or equal to the reporting trigger threshold; a data packet of the at least two sets of delay information is not transmitted as a PDU of a MAC layer; a data amount of the data packet of the at least two sets of delay information is not reported in the enhanced delay status report; the first object is configured with information indicating that the enhanced delay status report is used; and the target resource is determined to be used for carrying the enhanced delay status report based on the LCP result.

[0221] The first object can be an LCG or an LCH or a MAC entity.

[0222] In the embodiments of the present application, when the LCG or LCH is configured to support the type of the delay status report and the enhanced delay status report, the terminal device can determine whether to actually perform the reporting of the delay status report or the reporting of the enhanced delay status report based on the judgment of the reporting condition, for example, determine the delay reporting type according to the number of sets of delay information, or for example, determine the delay reporting type according to the configuration information of the first object including the LCG or the LCH or the MAC entity. In the case where the first reporting condition is met, the reporting of the delay status report is performed; and in the case where the second reporting condition is met, the reporting of the enhanced delay status report is performed.

[0223] Optionally, the reporting of the delay status report or the reporting of the enhanced delay status report performed in the step 301 comprises: performing the reporting of the delay status report for the LCG or the LCH if the third reporting condition is met; performing the reporting of the enhanced delay status report for the LCG or the LCH if the fourth reporting condition is met.

[0224] The third reporting condition comprises at least one of the following conditions: the logical channel group LCG or the logical channel LCH includes only one set of delay information; the remaining time of the set of delay information included in the logical channel group LCG or the logical channel LCH is less than or equal to the reporting trigger threshold; the first object is configured with information indicating that the delay status report is used; the first object is not configured with information indicating that the enhanced delay status report is used; and the target resource is determined to be used to carry the delay status report based on the logical channel priority LCP result.

[0225] The fourth reporting condition comprises at least one of the following conditions: the logical channel group LCG or the logical channel LCH includes at least two sets of delay information; the remaining time of at least one of the two sets of delay information included in the logical channel group LCG or the logical channel LCH is less than or equal to the reporting trigger threshold; the first object is configured with information indicating that the enhanced delay status report is used; and the target resource is determined to be used to carry the enhanced delay status report based on the logical channel priority LCP result.

[0226] In the embodiments of the present application, when the LCG or the LCH is configured to support the type of the delay status report and the enhanced delay status report, the terminal device can determine whether the LCG or the LCH actually performs the reporting of the delay status report or the reporting of the enhanced delay status report according to the granularity of each LCG or LCH and in combination with the judgment of the reporting condition, for example, determining the delay reporting type according to the number of sets of delay information of each LCG or LCH, and for example, determining the delay reporting type of each LCG or LCH according to the configuration information of the first object including the LCG or the LCH or the MAC entity. In the case of meeting the third reporting condition, the reporting of the delay status report is performed; in the case of meeting the fourth reporting condition, the reporting of the enhanced delay status report is performed.

[0227] The first reporting condition, the second reporting condition, the third reporting condition, and the fourth reporting condition are used to determine whether to report in the DSR or EDSR assembly and reporting process.

[0228] In addition, when there is no resource for sending the DSR and / or the EDSR, and there is no scheduling request SR currently being processed for the DSR and / or the EDSR trigger, and the scheduling request SR is the same as the logical channel triggering the DSR and / or the EDSR, the scheduling request SR is triggered.

[0229] It should be noted that if the embodiment of the present application reports the delay information with PDU set as the granularity, the LCG or LCH in the first reporting condition, the second reporting condition, the third reporting condition and the fourth reporting condition can be replaced by PDU set. For example, the at least two groups of delay information in the logical channel group LCG or the logical channel LCH in the fourth reporting condition can be replaced by the at least two groups of delay information in the PDU set. Wherein, the granularity based on the characteristics of the PDU set is considered.

[0230] In some possible implementation manners, the reporting configuration information includes a reporting trigger threshold of the delay status report and a plurality of remaining time thresholds of the enhanced delay status report; the reporting of the enhanced delay status report is performed based on that a first trigger condition or a second trigger condition is met; the reporting of the delay status report is performed based on that the first trigger condition and / or the second trigger condition is not met and a third trigger condition is met.

[0231] The first trigger condition, the second trigger condition and the third trigger condition are used to trigger the trigger process of the DSR / EDSR.

[0232] The first trigger condition includes that: the remaining time is less than or equal to the reporting trigger threshold of the enhanced delay status report; at least one logical channel group LCG or logical channel LCH includes at least two groups of delay information; the data to be transmitted corresponding to the at least two groups of delay information is not transmitted as a protocol data unit PDU of a medium access control MAC layer; the data amount of the data to be transmitted corresponding to the at least two groups of delay information is not reported in the delay status report and / or the enhanced delay status report; the logical channel group LCG or the logical channel LCH does not perform the reporting of the enhanced delay status report; the minimum value of the remaining time of the data to be transmitted in the LCG or the LCH is less than or equal to the reporting trigger threshold of the enhanced delay status report, and the data packet to be transmitted is not transmitted as a protocol data unit PDU of a medium access control MAC layer or the data amount of the data to be transmitted is not reported in the delay status report and / or the enhanced delay status report.

[0233] The second trigger condition includes that: the logical channel group LCG or the logical channel LCH includes only one group of delay information, and the one group of delay information does not meet the reporting trigger threshold of the delay status report; the logical channel group LCG or the logical channel LCH does not perform the reporting of the enhanced delay status report; the minimum value of the remaining time of the data to be transmitted in the LCG or the LCH is less than or equal to the reporting trigger threshold of the enhanced delay status report, and the data to be transmitted is not transmitted as a protocol data unit PDU of a medium access control MAC layer.

[0234] The third trigger condition comprises: each logical channel group (LCG) or logical channel (LCH) includes only one set of delay information; the remaining time is less than or equal to a reporting trigger threshold of the delay status report; the delay information corresponding to the to-be-transmitted data is not transmitted as a protocol data unit (PDU) of a medium access control (MAC) layer; the data volume of the delay information corresponding to the to-be-transmitted data is not reported in the delay status report and / or the enhanced delay status report; and optionally, the remaining time is the minimum value of the remaining time of the to-be-transmitted data in the LCG or LCH.

[0235] In the embodiments of the present application, when the LCG or LCH is configured to support the type of the delay status report and the enhanced delay status report, the terminal device can determine whether to actually perform the reporting of the delay status report or the reporting of the enhanced delay status report based on the judgment of the trigger condition. When the first trigger condition or the second trigger condition is met, the reporting of the enhanced delay status report is performed; and when the first trigger condition and the second trigger condition are not met, and the third trigger condition is met, the reporting of the delay status report is performed.

[0236] It should be noted that, if the PDU set is used as the granularity of the delay information reporting in the embodiments of the present application, the LCG or LCH in the first trigger condition, the second trigger condition and the third trigger condition can be replaced by the PDU set. For example, the first trigger condition that at least one logical channel group (LCG) or logical channel (LCH) includes at least two sets of delay information can be replaced by the first trigger condition that at least one PDU set includes at least two sets of delay information. The granularity based on the characteristics of the PDU set can be considered.

[0237] Optionally, the at least two sets of delay information comprise: a first remaining time and a second remaining time.

[0238] The first remaining time is less than or equal to a minimum remaining time threshold, the second remaining time is greater than the minimum remaining time threshold and less than or equal to a maximum remaining time threshold, or the first remaining time is less than or equal to the maximum remaining time threshold, and the second remaining time is in a different remaining time interval from the first remaining time; and the remaining time interval is determined based on a plurality of remaining time thresholds.

[0239] Further, in the first trigger condition, the at least two groups of remaining time can include a first remaining time and a second remaining time, the first remaining time is a remaining time corresponding to the first to-be-transmitted data packet, and the second remaining time is a remaining time corresponding to the second to-be-transmitted data packet; wherein, the first trigger condition can further include: the first remaining time is less than or equal to a minimum remaining time threshold, the second remaining time is greater than the minimum remaining time threshold and less than or equal to a maximum remaining time threshold, or the first remaining time is less than or equal to the maximum remaining time threshold, and the second remaining time is in a different remaining time interval from the first remaining time; wherein, the minimum remaining time threshold is a minimum threshold value in the plurality of remaining time thresholds, and the maximum remaining time threshold is a maximum threshold value in the plurality of remaining time thresholds. It can be understood that the remaining time interval is determined based on the plurality of remaining time thresholds.

[0240] The first trigger condition is described below in combination with a remaining time diagram of to-be-transmitted data shown in FIG. 4, the plurality of remaining time thresholds are 3 ms, 5 ms, 8 ms and 10 ms, and then the corresponding remaining time intervals are 0 ms-3 ms, 3 ms-5 ms, 5 ms-8 ms, 8 ms-10 ms and an interval greater than 10 ms. Among them, the first service data unit SDU1 is a general term of data packets with a remaining time less than or equal to the minimum remaining time threshold (3 ms), and the second service data unit SDU2 is a general term of data packets with a remaining time greater than the minimum remaining time threshold (3 ms) and less than or equal to the maximum remaining time threshold (10 ms), that is, the first remaining time of SDU1 is less than or equal to the minimum remaining time threshold, and the second remaining time of SDU2 is greater than the minimum remaining time threshold and less than or equal to the maximum remaining time threshold.

[0241] The first trigger condition is described below in combination with another remaining time diagram of to-be-transmitted data shown in FIG. 5, the plurality of remaining time thresholds and the remaining time intervals formed thereby are the same as shown in FIG. 4, the first service data unit SDU1 is a general term of data packets with a remaining time less than or equal to the maximum remaining time threshold (10 ms), and the second service data unit SDU2 has a remaining time in a different remaining time interval from the remaining time of SDU1, that is, the first remaining time of SDU1 is less than or equal to the maximum remaining time threshold (10 ms), and the second remaining time of SDU2 is in a different remaining time interval from the first remaining time of SDU1 (for example, the first remaining time is in the 0 ms-3 ms remaining time interval, and the second remaining time is in the 5 ms-8 ms remaining time interval).

[0242] In the embodiments of the present application, when different to-be-transmitted data packets meet different residual time threshold requirements, enhanced delay status reporting is performed, and the enhanced delay status reporting can include multiple sets of delay information, so that more detailed residual time information can be reported for different to-be-transmitted data packets.

[0243] Optionally, according to the residual time and the reporting configuration information, the reporting of the delay status report or the reporting of the enhanced delay status report is performed, including: if the logical channel group LCG or the logical channel LCH includes only one set of delay information, triggering the delay status report for the logical channel group LCG or the logical channel LCH according to the residual time and the reporting configuration information; if the logical channel group LCG or the logical channel LCH includes at least two sets of delay information, triggering the enhanced delay status report for the logical channel group LCG or the logical channel LCH according to the residual time and the reporting configuration information.

[0244] In the embodiments of the present application, the number of sets of delay information included in the logical channel group LCG or the logical channel LCH can be directly used to determine the corresponding reporting mode, when the LCG or the LCH includes only one set of delay information, triggering the delay status report for the LCG or the LCH; when the LCG or the LCH includes at least two sets of delay information, triggering the enhanced delay status report for the LCG or the LCH.

[0245] It should be noted that if the PDU set is used as the granularity of delay information reporting in the embodiments of the present application, the method can further include: if the PDU set includes only one set of delay information, triggering the delay status report for the PDU set according to the residual time and the reporting configuration information. Using the PDU set as the granularity can consider the characteristics of the PDU set as the granularity.

[0246] The following describes another method of delay status reporting in conjunction with the flowchart of the method shown in FIG. 6, including a first logical channel group LCG1, a second logical channel group LCG2, and a third logical channel group LCG3. The LCG1 and the LCG3 each include two sets of delay information, so the enhanced delay status report EDSR is triggered for the LCG1 and the LCG3. The LCG2 includes only one set of delay information, so the delay status report DSR is triggered for the LCG2. In the embodiments of the present application, the number of sets of delay information included in the logical channel group is used to determine the reporting mechanism of the delay status, the reporting mechanism of the DSR is used for the LCG including only one set of delay information, because the DSR can carry one set of delay information and occupies less data resource than the EDSR; the reporting mechanism of the EDSR is used for the LCG including at least two sets of delay information, because the EDSR can carry multiple sets of delay information, ensuring the effectiveness and efficiency of delay information reporting.

[0247] It should be noted that FIG. 6 is an illustration made with LCG as the granularity of delay information reporting, and a person skilled in the art can also implement the scheme with logical channel LCH as the granularity of delay information reporting, and FIG. 6 does not limit the embodiments of the present application.

[0248] Optionally, according to the remaining time and the reporting configuration information, the reporting of the delay status report or the reporting of the enhanced delay status report is performed, including: if at least one of the plurality of logical channel groups LCGs includes at least two groups of delay information, triggering the enhanced delay status report for the plurality of logical channel groups LCGs; if at least one of the plurality of logical channels LCHs includes at least two groups of delay information, triggering the enhanced delay status report for the plurality of logical channels LCHs.

[0249] In the embodiments of the present application, when there are a plurality of LCGs, and at least one of the plurality of LCGs includes at least two groups of delay information, the enhanced delay status report is triggered for the plurality of LCGs; when there are a plurality of LCHs, and at least one of the plurality of LCHs includes at least two groups of delay information, the enhanced delay status report is triggered for the plurality of LCHs.

[0250] It should be noted that if the PDU set is used as the granularity of delay information reporting in the embodiments of the present application, the method can also include: if at least one of the plurality of PDU sets includes at least two groups of delay information, triggering the enhanced delay status report for the plurality of PDU sets. Wherein, the PDU set can be considered as the granularity based on the characteristics of the PDU set.

[0251] The following describes another method of delay status reporting in conjunction with the flow diagram of the method shown in FIG. 7, including a first logical channel group LCG1, a second logical channel group LCG2, and a third logical channel group LCG3, wherein LCG1 includes two groups of delay information, LCG2 includes one group of delay information, and LCG3 includes three groups of delay information. Since at least one of the three logical channel groups includes at least two groups of delay information, the enhanced delay status report is triggered for the three logical channel groups. In the embodiments of the present application, when there is at least one LCG including at least two groups of delay information, the reporting mechanism of EDSR is uniformly used for all LCGs. At this time, for part of the LCGs including only one group of delay information, there is no need to assemble a delay status report DSR data packet separately, thereby improving the efficiency of delay information reporting.

[0252] It should be noted that FIG. 7 is an illustration made with LCG as the granularity of delay information reporting, and a person skilled in the art can also implement the scheme with logical channel LCH as the granularity of delay information reporting, and FIG. 7 does not limit the embodiments of the present application.

[0253] Optionally, the method for reporting delay status provided by the embodiments of the present application can further include: canceling the reporting of the enhanced delay status report of the logical channel group LCG or the logical channel LCH based on the fact that the logical channel group LCG or the logical channel LCH only includes one set of delay information.

[0254] Specifically, if there is only one set of delay information left in the LCG or the LCH, and the LCG or the LCH is performing the reporting of the enhanced delay status report, the reporting of the enhanced delay status report performed by the LCG or the LCH can be canceled at this time. Since there is only one set of delay information left in the LCG or the LCH, the reporting of the EDSR is not needed at this time, and the condition of the delay information can be combined to determine whether the reporting of the DSR is performed, thereby saving the amount of reported data and reducing the communication cost.

[0255] It should be noted that if the PDU set is used as the granularity of the reporting of the delay information in the embodiments of the present application, the above method can be replaced by canceling the reporting of the enhanced delay status report of the PDU set based on the fact that the PDU set only includes one set of delay information. The granularity based on the characteristics of the PDU set can be considered as the granularity.

[0256] Further, the reporting of the enhanced delay status report of the logical channel group LCG or the logical channel LCH can also be canceled in the case where the first canceling condition is met. The first canceling condition includes at least one of the following conditions: the first data packet has been discarded or the second data packet has been discarded; the first data packet or the second data packet has been transmitted as a protocol data unit PDU of a media access control MAC layer; the EDSR including the first data packet or the second data packet has been reported; the LCH or the LCG associated with the first data packet or the second data packet triggers the reporting of the EDSR, and the first data packet and the second data packet have not been transmitted in a MAC PDU; the remaining time of the first data packet is less than or equal to a reporting trigger threshold; and the remaining time of the second data packet is less than or equal to a maximum value of a plurality of remaining time thresholds.

[0257] In the case where the first canceling condition is met, the reporting of the enhanced delay status report of the LCG or the LCH can be canceled. For example, the related data packets have been discarded, or the related data packets have been transmitted as the PDU of the MAC layer, and accordingly there is no need to report the to-be-transmitted data packets. At this time, the reporting of the enhanced delay status report can be canceled to avoid the meaningless reporting of the delay information and the waste of resources.

[0258] Optionally, if the second cancellation condition is met, canceling reporting of the enhanced delay status report for the plurality of logical channel groups (LCGs) or LCHs, and reporting of the delay status report for the plurality of LCGs or LCHs; wherein the second cancellation condition comprises: each of the plurality of LCGs or LCHs only has one set of delay information left, and each of the plurality of LCGs or LCHs has the one set of delay information left that meets the reporting trigger threshold of the delay status report.

[0259] Specifically, when each of the plurality of LCGs or each of the plurality of LCHs only has one set of delay information left, and each of the plurality of LCGs or each of the plurality of LCHs has the one set of delay information left that meets the reporting trigger threshold of the delay status report, i.e., the remaining time in the delay information is less than the reporting trigger threshold of the delay status report, reporting of the enhanced delay status report (EDSR) for the plurality of LCGs or LCHs can be canceled, and reporting of the delay status report (DSR) for the plurality of LCGs or LCHs is performed.

[0260] It can be understood that, in the actual reporting process of the enhanced delay status report (EDSR), the terminal device needs to wait for uplink resources that can be used to carry the enhanced delay status report (EDSR), for example, the terminal device schedules a request (SR) for uplink shared channel (UL-SCH) resources, and the logical channel priority (LCP) result indicates that the resources can be used to carry the enhanced delay status report (EDSR). However, during the process of requesting the uplink resources to determining that the uplink resources are used to transmit the enhanced delay status report (EDSR), the data packets to be transmitted in the LCG or LCH can be discarded, and therefore the delay information included in the LCG or LCH can change accordingly. In the embodiments of the present application, the delay status reporting mechanism is adjusted based on the dynamic change of the delay information included in the LCG or LCH, to ensure the accuracy and efficiency of the delay status reporting mechanism.

[0261] It should be noted that, if the PDU set is used as the granularity of the delay information reporting in the embodiments of the present application, the LCG or LCH in the first cancellation condition and the second cancellation condition in the above method can be replaced by the PDU set. For example, the first data packet or the second data packet associated with the LCH or the LCG triggers the reporting of the EDSR in the first cancellation condition can be replaced by the first data packet or the second data packet associated with the PDU set triggering the reporting of the EDSR. Wherein, the PDU set is used as the granularity to consider the characteristics based on the PDU set.
