The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone.

For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0025] Currently, with people's pursuit of speed, latency, high-speed mobility, and energy efficiency, as well as the diversity and complexity of services in future life, the 3GPP international standards organization has begun developing 5G. The main application scenarios for 5G are: enhanced mobile ultra-wideband (eMBB), ultra-reliable low-latency communication (URLLC), and massive machine-type communication (mMTC). eMBB still aims to provide users with multimedia content, services, and data, and its demand is growing rapidly. On the other hand, because eMBB may be deployed in different scenarios, such as indoors, urban areas, and rural areas, its capabilities and needs vary considerably, so generalizations cannot be made; a detailed analysis based on the specific deployment scenario is necessary. Typical applications of URLLC include: industrial automation, power automation, remote medical operations (surgery), and traffic safety assurance. Typical characteristics of mMTC include: high connection density, small data volume, latency-insensitive services, low module cost, and long module lifespan. The New Radio Access Network (NR) can also be deployed independently. In a 5G network environment, to reduce air interface signaling and quickly restore radio connections and data services, a new Radio Resource Control (RRC) state is defined: RRC_INACTIVE. This state differs from RRC_IDLE and RRC_ACTIVE. RRC_IDLE indicates that mobility is based on UE-based cell selection and reselection, paging is initiated by the CN, and the paging area is configured by the CN. There is no UE AS context on the base station side. There is no RRC connection. RRC_CONNECTED: An RRC connection exists, and the base station and UE have a UE AS context. The network side knows the UE's location at the specific cell level. Mobility is network-controlled. Unicast data can be transmitted between the UE and the base station. RRC_INACTIVE: Mobility is based on UE-based cell selection and reselection, a connection exists between the CN and NR, the UE AS context exists on a specific base station, paging is triggered by the RAN, the RAN-based paging area is managed by the RAN, and the network side knows the UE's location at the RAN-based paging area level.

[0026] The eNodeB can allocate downlink or uplink radio resources to each UE based on downlink buffered data in the eNodeB and Buffer Status Reports (BSRs) received from the UE. In other words, during 5G NR BSR, the UE uses the BSR to inform the serving base station of its uplink buffered data volume, allowing the base station to schedule the UE based on this data volume information. To save on BSR reporting overhead, a grouped reporting method is used. Each uplink logical channel corresponds to a Logical Channel Group (LCG), and multiple uplink logical channels can correspond to the same LCG. The mapping between logical channel LCs and LCGs is configured by the network RRC. The UE reports BSRs based on LCGs. Each UE in NR can support up to 8 LCGs. The triggering conditions for BSR are as follows: 1. Uplink data arrives on a higher-priority logical channel of the UE, triggering a regular BSR; 2. The padding portion of the uplink resources allocated to the UE after carrying other uplink data can carry a BSR MAC CE, triggering a padding BSR; 3. The retransmission BSR timer retxBSR-Timer times out, and at least one uplink logical channel currently has uplink data to be transmitted, triggering a regular BSR; 4. The periodic BSR timer periodicBSR-Timer times out, triggering a periodic BSR. If multiple logical channels trigger a regular BSR simultaneously, each of these logical channels will trigger a separate regular BSR. BSR can be carried through BSR MAC CE. If a terminal triggers a regular BSR, but the terminal lacks uplink resources for transmitting new data or the uplink resources allocated to the terminal for transmitting new data cannot carry the data of the uplink logical channel that triggered the regular BSR, the terminal triggers an uplink scheduling request (SR).

[0027] At the 3GPP RAN #88e meeting, a research project entitled "eXtended Reality (XR) and cloud game (CG) evaluations for NR" was adopted. This project studies services including AR (Augmented Reality) / VR (Virtual Reality) / Cloud gaming, etc. A major service of XR / CG is video streaming, with arrival rates (measured in frames per second) of 30fps, 60fps, 90fps, and 120fps. The corresponding video stream periods are {33.33ms, 16.67ms, 11.11ms, 8.33ms}. Specific characteristics of XR data include variable packet size and a relatively large average. For example, in AR / VR with a data rate of 100Mbps, the average uplink packet size is 20833 bytes, the maximum is 31250 bytes, and the minimum is 10417 bytes. That is, the size of the data packet to be transmitted in each cycle is between [10417 bytes, 31250 bytes]. In a real system with a bandwidth of 100M, transmitting a data packet of 20833 bytes requires approximately 4 time slots of transmission resources.

[0028] In 3GPP RAN2#120, RAN2 determines the reporting of delay information associated with data volume. RAN2 will incorporate data volume information associated with delay information (e.g., remaining time) into the MACCE. Further research is needed on FFS, if this is an extended BSR or a new format. How this is done (e.g., what is specifically reported) and how to ensure this information is up-to-date, for example, considering UL scheduling delays.

[0029] In 3GPP RAN2#122, RAN2 determines the remaining time by deriving the Packet Data Convergence Protocol (PDCP) drop timer value. The UE calculates the remaining time based on the PDCP drop timer value. If the UE reports one or more values, it is considered FFS (Free Time Forecast). How is FFS modeled in the PDCP specification? What FFS does the UE support?

[0030] In 3GPP RAN2#123, further agreements were reached regarding delay status reporting (DSR), including: 1) The network can configure whether the UE triggers delay status reporting. Further research into the FFS is needed, especially if each LCG has certain thresholds. 2) When the UE triggers reporting of LCG delay information, the UE also reports the buffer status associated with the remaining time. RAN2 aims to define a single MAC CE for DSR reporting (including buffer status). Further research into the FFS is needed, whether this extends the BSR MAC CE or introduces a new MAC CE. 3) Assumption: Define a new, separate MAC CE for DSR (remaining delay and associated data volume) reporting, for example, DSR reporting is not coupled with BSR reporting. Detailed definitions of associated data volume are needed for further research into the FFS. 4) Support for threshold-based DSR reporting, for example, triggering DSR reporting when the remaining delay of a Packet Data Unit (PDU) PDU / PDU set is below a threshold configured by the NW. The threshold is configured based on the LCG. Whether the FFS supports configuring multiple thresholds for an LCG is also considered. The remaining time is defined as FFS.

[0031] The Delay Status Report (DSR) procedure is used to provide the delay status of UL data to the serving gNB. The delay status includes the remaining time of the UL data, which is based on the value of the PDCP discardTimer associated with the first symbol transmitted on the Physical Uplink Control Channel (PUSCH) that transmits the DSR (as specified in Clause 7.3 of TS38.323[4]), and the amount of data associated with the reported remaining time. The Radio Resource Control (RRC) controls the DSR operation by configuring the following parameter: the remaining time threshold of the UL data configured to trigger the DSR of the LCG. The MAC entity triggers the DSR when the remaining time of the PDU in the LCG (if configured for DSR) is shorter than its associated remaining time threshold. It can also be updated after more agreements are reached, for example, a more precise definition of the "amount of data associated with the reported remaining time" is needed. Further research is needed on the definition of the FFS remaining time. Further research is needed if the LCG reports one or more values. If the reported delay is below the threshold, then FFS is needed. However, the details of how the UE reports DSR are currently unclear. This application provides a latency information processing method to solve this problem.

[0032] The delay information processing method provided in this application embodiment can be applied to, for example... Figure 1 In the application scenarios shown. For example... Figure 1As shown, this scenario includes network 01 and network 02, which can be different types of networks. It also includes base stations 03, 04, 05, 06, 07, and 08. Base stations 04, 06, and 07 can be macro base stations, while base stations 03, 05, and 08 can be micro base stations. Each base station can communicate with the base stations via either network 01 or network 02. The scenario also includes UEs 09, 010, 011, 012, and 013, which can communicate with the base stations via the network. Figure 1 As shown, this scenario includes a large number of transmission and reception points. Multiple transmission and reception points can constitute a virtual cell, which can serve one or more UEs. The transmission and reception points can be network-side devices or terminal devices. Network-side devices can include macro base stations, micro base stations, and core network devices, such as Mobility Management Entities (MMEs) and Serving Gateways (S-GWs). This application embodiment does not impose any limitations. It should be noted that in this application embodiment… Figure 1 This is merely an example of a network architecture and does not constitute a limitation on the application scenarios of the embodiments of this application.

[0033] A UE can be a wireless terminal, which can be a device providing voice and / or other service data connectivity to a user, a handheld device with wireless connectivity, or other processing devices connected to a wireless modem. The wireless terminal can communicate with one or more core networks via a Radio Access Network (RAN). The wireless terminal can be a mobile terminal, such as a mobile phone (or "cellular" phone) or a computer with a mobile terminal, for example, a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device, exchanging voice and / or data with the RAN. The wireless terminal can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile, remote station, remote terminal, access terminal, user terminal, user agent, user device, or user equipment, without limitation herein. For example, the UE can be, but is not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can be smart speakers, smart TVs, smart air conditioners, smart in-vehicle devices, etc. Portable wearable devices can be smartwatches, smart bracelets, head-mounted devices, etc., and are not limited in this embodiment.

[0034] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0035] In one embodiment, such as Figure 2 As shown, a time delay information processing method is provided, which is applied to... Figure 1 Taking the user terminal (UE) side as an example, the explanation includes the following steps: S201, under the first condition, trigger DSR, and / or report DSR.

[0036] The first condition can be a condition to avoid excessive DSR reporting, which can be pre-configured, pre-defined, or determined by RRC. Optionally, the first condition can include a preset period, i.e., triggering DSR when the preset period is met; or, reporting DSR when the preset period is met; or, triggering and reporting DSR when the preset period is met. Optionally, the first condition can also include other conditions.

[0037] In this embodiment of the application, when the UE pre-transmits uplink data, it can determine whether a first condition is met. If the condition is met, a DSR can be triggered. Optionally, if the condition is met, a DSR can be reported if there are transmission resources available. Optionally, if the condition is met, a DSR can be triggered first, and the triggered DSR can be reported if there are transmission resources available. If the condition is not met, the UE may not trigger and / or report a DSR, or it may trigger an uplink scheduling request (SR).

[0038] The latency information processing method described in this application provides an implementation for UE to report DSR, namely, triggering and / or reporting DSR under a first condition. Furthermore, by limiting the reporting conditions for DSR, excessive DSR reporting can be avoided, thereby reducing the DSR reporting load.

[0039] In one embodiment, the first condition includes the DSR reporting cycle, that is, when executing S201 above, specifically: if the DSR reporting cycle is met, trigger DSR, and / or report DSR.

[0040] The aforementioned DSR reporting period is a reporting period set for a first object, which can be any one of UE, MAC entity, LCG, or LCH. The DSR reporting period can be pre-configured, pre-defined, or determined by RRC.

[0041] In this embodiment of the application, when the UE is pre-transmitting uplink data, it can be determined whether the DSR reporting period is met. If it is met, the DSR can be triggered. Optionally, if it is met, the DSR can be reported if there are transmission resources. Optionally, if it is met, the DSR can be triggered first, and the triggered DSR can be reported if there are transmission resources.

[0042] In one embodiment, the DSR reporting period includes a reporting timer, and / or, reporting the DSR if the reporting timer times out.

[0043] In this embodiment of the application, when the UE is pre-transmitting uplink data, it can determine whether the reporting timer has expired, and if it is determined that the timer has expired, the DSR is reported.

[0044] In one embodiment, the first condition includes a DSR triggering cycle, that is, when executing S201, specifically: if the DSR triggering cycle is met, trigger DSR, and / or report DSR.

[0045] The aforementioned DSR triggering period is a triggering period set for a first object, which can be any one of the UE, MAC entity, LCG, and LCH. The DSR triggering period can be pre-configured, pre-defined, or determined by RRC.

[0046] In this embodiment of the application, when the UE is pre-transmitting uplink data, it can be determined whether the trigger timer has timed out, and if it is determined that the timer has timed out, the DSR is triggered.

[0047] In one embodiment, the DSR triggering cycle includes a trigger timer, and / or, triggering the DSR if the trigger timer times out.

[0048] In this embodiment of the application, when the UE is pre-transmitting uplink data, it can be determined whether the trigger timer has timed out, and if it is determined that the timer has timed out, the DSR is triggered.

[0049] It should be noted that the reporting timer and the trigger timer can be the same timer or different timers.

[0050] In summary, based on the above related embodiments, Figure 2 The time delay information processing method includes at least one of the following: DSR is triggered only once during the DSR trigger cycle.

[0051] If the timer times out, DSR can be triggered.

[0052] When DSR is triggered, the corresponding trigger timer is started.

[0053] DSR triggers only once during DSR reporting.

[0054] If the reporting timer times out, a DSR can be reported.

[0055] When DSR is reported, the corresponding reporting timer is started.

[0056] Furthermore, for the first object, DSR can be triggered only once during the DSR triggering cycle.

[0057] Furthermore, for the first object, DSR can be triggered when the timer times out.

[0058] Furthermore, for the first object, DSR can be triggered when the timer times out.

[0059] Furthermore, for the first object, a corresponding trigger timer can be started when DSR is triggered.

[0060] Furthermore, for the first object, DSR can be triggered only once during DSR trigger reporting.

[0061] Furthermore, for the first object, a DSR can be reported when the reporting timer times out.

[0062] Furthermore, for the first object, a corresponding reporting timer can be started when DSR is reported.

[0063] The first object can be any one of the following: UE, Media Access Control (MAC) entity, London Capital Group (LCG), or Logical Channel (LCH).

[0064] In one embodiment, Figure 2 The delay information processing method described in the embodiment further includes the following steps: During the first disable timer operation, DSR is not triggered, and / or DSR is not reported.

[0065] In this embodiment of the application, when the UE transmits uplink data, it can be determined whether the first prohibition timer is running. If it is running, the DSR is not triggered; optionally, if it is running, the DSR is not reported; optionally, if it is running, the DSR is not triggered and the DSR is not reported. If it is determined that the first prohibition timer is not running, the DSR can be triggered and / or reported.

[0066] In one embodiment, the first disable timer can be enabled by at least one of the following conditions: DSR is triggered; DSR is reported; a MAC CE carrying DSR information is generated; DSR or DS information is carried in a MAC PDU or PUSCH; or a MAC PDU or Physical Uplink Shared Channel (PUSCH) carrying DSR or DS information is transmitted or has been transmitted.

[0070] In this embodiment of the application, a first prohibition timer is introduced for UE, or for MAC entity, or for LCG, or for LCH; optionally, when DSR is reported for UE, or for MAC entity, or for LCG, or for LCH, the above-mentioned first prohibition timer is enabled, and DSR information is not triggered or reported for UE, or for MAC entity, or for LCG, or for LCH; optionally, if the first prohibition timer for UE, or for MAC entity, or for LCG, or for LCH times out or does not run, DSR information for UE, or for MAC entity, or for LCG, or for LCH can be triggered or reported.

[0071] In one embodiment, Figure 2 The delay information processing method described in the embodiment further includes the following steps: Clear triggered DSR if at least one of the following conditions is met. Among them, at least one of the above situations includes: generating a MAC CE carrying DSR information; DSR or DS information has been reported; DSR or DS information is carried in a MAC PDU or PUSCH; or a MAC PDU or PUSCH carrying DSR or DS information has been transmitted or has been transmitted.

[0072] In this embodiment of the application, the UE can report DSR information via PUSCH or MAC CE. Optionally, for triggered DSR information, if the DSR information is included in PUSCH or MAC CE, that is, after the UE has reported the DSR information based on PUSCH or MAC CE, the triggered DSR can be canceled.

[0073] In one embodiment, Figure 2 The delay information processing method described in the embodiments further includes any one of the following steps: DSR information will not be triggered for the first object that has already triggered or is triggering DSR information.

[0074] For the first object that has reported or has already reported DSR information, DSR information will not be triggered, or DSR will not be reported.

[0075] This application involves various methods for preventing the triggering of DSR information, as well as methods for preventing the triggering and not reporting of DSR, namely: preventing the triggering of DSR information for the first object that has triggered DSR reporting; preventing the triggering of DSR information for the first object that has already triggered DSR information; preventing the triggering of DSR for the first object that has reported DSR; preventing the reporting of DSR for the first object that has reported DSR; preventing the reporting of DSR for the first object that has reported DSR; and preventing the reporting of DSR for the first object that has already reported DSR.

Optionally, if any data in the aforementioned LCG or LCH is triggered, other data cannot be triggered or reported; if the same data in the aforementioned LCG or LCH is triggered, other data cannot be triggered or reported.

[0078] In one embodiment, Figure 2 The first condition described in the embodiment may include at least one of the following: A new data, PDU, or PDU set has been reached; A new data, PDU, or PDU set arrives, and none of the new data, PDU, or PDU set triggers DSR information and / or reports DSR information; A new data, PDU, or PDU set arrives, and none of the new data, PDU, or PDU set triggers DSR information and / or reports DSR information, and the second condition is met; The latency of a new data, PDU, or PDU set is less than the threshold or within the first threshold. The latency of a new data, PDU, or PDU set is less than the threshold or within the first threshold, and none of the new data, PDU, or PDU set triggers DSR information and / or reports DSR information; The latency of a new data, PDU, or PDU set is less than a threshold or within a first threshold range, and none of the new data, PDU, or PDU set triggers DSR information and / or reports DSR information, and the second condition is met.

[0084] Alternatively, for data, PDUs, PDU sets, LCHs, LCGs, MAC entities, or UEs that have already reported DSRs, DSRs may not be triggered and / or may not be reported if the third condition is met.

[0085] In one embodiment, Figure 2 The delay information processing method described in the embodiment further includes the following steps: If the third condition is met, DSR will not be triggered for data, PDU, PDU set, LCH, LCG, MAC entity or UE that has already triggered DSR, and / or DSR will not be reported.

[0089] In one embodiment, Figure 2 The delay information processing method described in the embodiment further includes the following steps: If there is data, PDU, PDU set, LCH, LCG, MAC entity or UE that has already triggered DSR, DSR will not be triggered for the third object, and / or DSR will not be reported.

[0090] Alternatively, if there is data, PDU, PDU set, LCH, LCG, MAC entity or UE that has already reported DSR, DSR will not be triggered for the third object, and / or DSR will not be reported.

[0091] Alternatively, if there is data, PDU, PDU set, LCH, LCG, MAC entity or UE that has already triggered DSR, for the third object, if the fifth condition is met, DSR will not be triggered, and / or DSR will not be reported; Alternatively, if there is data, PDU, PDU set, LCH, LCG, MAC entity or UE that has already reported DSR, for the third object, if the fifth condition is met, DSR will not be triggered, and / or DSR will not be reported.

[0092] Alternatively, if the third condition is met, and there is data, PDU, PDU set, LCH, LCG, MAC entity or UE that has already triggered DSR, DSR will not be triggered for the third object, and / or DSR will not be reported.

[0094] Alternatively, if the third condition is met and there is data, PDU, PDU set, LCH, LCG, MAC entity or UE that has triggered DSR, then for the third object, if the fifth condition is met, DSR will not be triggered and / or DSR will not be reported.

[0095] Alternatively, if the third condition is met, and there is data, PDU, PDU set, LCH, LCG, MAC entity or UE that has already reported DSR, then for the third object, if the fifth condition is met, DSR will not be triggered, and / or DSR will not be reported.

[0096] The third object in the above embodiments includes any one of the following: PDUs that have already triggered and / or reported DSR; The PDU set corresponding to the PDUs that have triggered and / or reported DSR; The data burst corresponding to the PDU that has triggered and / or reported DSR; LCH corresponding to the PDU that has already triggered and / or reported DSR; The LCG corresponding to the PDU that has triggered and / or reported DSR; The MAC entity corresponding to the PDU that has triggered and / or reported DSR; The UE corresponding to the PDU that has triggered and / or reported DSR; PDU sets that have already triggered and / or reported DSR; The data burst corresponding to the PDU set that has already triggered and / or reported DSR; The LCH corresponding to the PDU set that has already triggered and / or reported DSR; LCG corresponding to the PDU set that has already triggered and / or reported DSR; The MAC entity corresponding to the PDU set that has triggered and / or reported DSR; The UE corresponding to the PDU set that has already triggered and / or reported DSR; A data burst that has been triggered and / or reported DSR has occurred; LCH corresponding to the data burst that has been triggered and / or reported DSR; The LCG corresponding to the data burst that has already triggered and / or reported DSR; The MAC entity corresponding to the data burst that has triggered and / or reported DSR; The UE corresponding to the data burst that has triggered and / or reported DSR; LCHs that have already triggered and / or reported DSRs; The LCG corresponding to the LCH that has already triggered and / or reported DSR; The MAC entity corresponding to the LCH that has triggered and / or reported DSR; The UE corresponding to the LCH that has already triggered and / or reported DSR; LCGs that have already triggered and / or reported DSR; The MAC entity corresponding to the LCG that has triggered and / or reported DSR; UEs corresponding to LCGs that have already triggered and / or reported DSR; MAC entities that have already triggered and / or reported DSR; The MAC entity corresponding to the MAC entity that has triggered and / or reported DSR; UEs that have already triggered and / or reported DSR.

[0097] The above method can be illustrated by example: For an LCG, if it is configured to report DSR, the data / PDU / PDU set that triggers DSR cannot trigger new DSR reporting; and / or, data / PDU / PDU sets that have already reported DSR information cannot trigger new DSR reporting. Optionally, the above can also be configured to report DSR for a UE, MAC entity, or LCH.

[0098] Optionally, for an LCG, if DSR information can be reported, when a new data / PDU / PDU set arrives, the new data / PDU / PDU set, or the LCG / LCH corresponding to the new data / PDU / PDU set, can trigger a new DSR report; for an LCG, if DSR information can be reported, when a new data / PDU / PDU set arrives, or if a new data / PDU / PDU set exists and has not triggered and / or reported DSR information, and the third condition (fourth condition or fifth condition) is met, the new data / PDU / PDU or the corresponding LCG / LCH can trigger new DSR information, or report DSR information; optionally, the above can also be configured to report DSR for a UE, or a MAC entity, or an LCH.

[0099] Optionally, for the DSR reporting function or the DSR triggering function, if an LCG or LCH that has already triggered DSR reporting is no longer triggered under the third condition (fourth condition or fifth condition), or if an LCG or LCH that has already reported DSR information is no longer triggered or reported DSR information under the second condition.

[0100] In one embodiment, any one of the second, third, fourth, or fifth conditions in the above embodiments may include duration and / or threshold.

[0101] Here, "duration" represents the duration during which DSR reporting has been triggered. Specifically, when executing step S210 above, the following steps are executed: LCGs or LCHs that have already triggered DSR reporting will not trigger DSR reporting again within the specified duration. Alternatively, when executing step S211 above, the following steps are executed: LCGs or LCHs that have already reported DSR information will not trigger or report DSR information again within the specified duration. Optionally, new DSRs are not allowed to be triggered or reported within the specified duration.

[0102] Different thresholds can be assigned to different objects, or alternatively, different objects can be assigned to the same threshold. When different thresholds are assigned, new DSRs can be triggered or reported. When the same threshold is assigned, new DSRs cannot be triggered or reported.

[0103] The above method can be illustrated by example: For the DSR reporting function or DSR triggering function, PDUs or PDU sets that have already triggered DSR reporting will no longer trigger DSR reporting, or PDUs or PDU sets that have already reported DRS information will no longer trigger or report DS information.

[0104] For the DSR reporting function or DSR triggering function, if a PDU or PDU set that has already triggered DSR reporting will no longer trigger DSR reporting under the third condition (fourth or fifth condition), or if a PDU or PDU set that has already reported DSR information will no longer trigger or report DSR information under the third condition (fourth or fifth condition).

[0122] Here, the first LCG refers to any LCG, and the first LCH refers to any LCH within the LCG. The second time can be pre-configured, pre-defined, or determined by RRC.

[0123] In this embodiment of the application, optionally, if the first LCG has already triggered DSR information, DSR reporting will not be triggered again in the second time period, regardless of whether the first LCG or other LCG is triggered.

[0124] In this embodiment of the application, optionally, if the first LCG triggers DSR reporting, and the second LCG meets the DSR triggering condition, then DSR information for the UE or for the second LCG can be triggered, wherein the DSR information for the UE is the DSR information for the first LCG and the second LCG.

[0125] In this embodiment of the application, optionally, if the first LCG triggers DSR reporting, and the second LCG meets the DSR triggering condition, and the DSR triggering threshold of the second LCG is lower than the DSR triggering threshold of the first LCG, then DSR information for the UE or for the second LCG can be triggered; and / or, if the first LCG triggers DSR reporting, and the second LCG meets the DSR triggering condition, and the data priority of the second LCG is higher than the data priority of the first LCG, then DSR information for the UE or for the second LCG can be triggered.

[0127] The methods in the above embodiments are illustrated by example: If the first LCG has already triggered DSR reporting, DSR reporting will not be triggered again during the second time period (regardless of whether it was triggered by the first LCG or another LCG). Alternatively, if the first LCG has triggered DSR reporting, and the second LCG meets the DSR triggering conditions, then DSR can be triggered for the UE or for the second LCG. Or, if the first LCG has already triggered DSR reporting, and the second LCG meets the DSR triggering conditions, and the second LCG's DSR triggering threshold is lower than the DSR triggering threshold that triggered the first LCG's DSR, then DSR can be triggered for the UE or for the second LCG.

[0128] If a first LCH in an LCG has already triggered a DSR report, no further DSR reports will be triggered in the second time period (regardless of whether the first LCH or any other LCH triggered it). Alternatively, if an LCG has already triggered a DSR report, and it was triggered by the first LCH or a PDU / PDU set within the first LCH, and if the second LCH or a PDU / PDU set within the second LCH meets the DSR triggering conditions, then a DSR can be triggered for the second LCH, or for the UE (first LCG and second LCG).

And / or, if an LCG has already triggered DSR reporting, and it was triggered by the first LCH or a PDU / PDU set in the first LCH, and if the second LCH or a PDU / PDU set in the second LCH meets the DSR triggering conditions, and the data priority of the second LCH is higher than the data priority of the first LCH, then DSR can be triggered for the second LCG, or for the UE (first LCG and second LCG). Optionally, the DS information corresponding to the first LCH may or may not be reported.

[0129] If the first LCH in an LCG has already triggered a DSR report, no further DSR reports will be triggered in the second time period (regardless of whether it was triggered by the first LCH or another LCH). Alternatively, if an LCG has already triggered a DSR report, and it was triggered by the first LCH or a PDU / PDU set within the first LCH, and if the second LCH or a PDU / PDU set within the second LCH meets the DSR triggering conditions, then a DSR can be triggered for the second LCH, or for the UE (first LCG and second LCG). Alternatively, if an LCG has already triggered a DSR report, and it was triggered by the first LCH or a PDU / PDU set within the first LCH, and if the second LCH or a PDU / PDU set within the second LCH meets the DSR triggering conditions, and the DSR triggering threshold of the second LCH is lower than the DSR triggering threshold of the first LCH that triggered the LCG's DSR, then a DSR can be triggered for the second LCH, or for the UE (first LCG and second LCG). And / or, if an LCG has already triggered DSR reporting, and it was triggered by the first LCH or a PDU / PDU set in the first LCH, and if the second LCH or a PDU / PDU set in the second LCH meets the DSR triggering conditions, and the data priority of the second LCH is higher than the data priority of the first LCH, then DSR can be triggered for the second LCH, or for the UE (first LCG and second LCG). Optionally, the DS information corresponding to the first LCH may or may not be reported.

[0130] In one embodiment, the MAC CE including DSR is a fixed-length MAC CE, or a variable-length MAC CE.

[0131] Optionally, the length of the MAC CE mentioned above is related to any of the following; The number of LCGs that reported DSR information; The number of DSR messages reported; Does the LCG configured to report DSR information have DSR information? The number of DSR information items that need to be reported or reported in the LCG configured to report DSR information.

[0132] The method in the above embodiments is illustrated by an example: the MAC CE including DSR information is a variable-size MAC CE. Optionally, the length of the MAC CE is affected by the number of LCGs that report DSR, or by whether the LCGs configured to report DSR have DS information to report, or by how much latency information in the LCGs configured to report DSR needs to be reported.

[0164] Optionally, the DSR information includes information on the amount of data to be transmitted for the corresponding delay segment of the sixth object, or information on all the data to be transmitted for the sixth object.

[0165] Based on the above embodiments, a specific optional implementation method is given: If the reported latency is the latency of a PDU set, then any PDU in the PDU set can trigger the latency reporting, or only a specific PDU can trigger latency reporting (such as the first PDU). Alternatively, the latency information of a PDU set can be reported, and the information can be the latency information of any PDU set, or the latency information of a specific PDU set.

[0166] Optionally, once PDU set-based operation is enabled, the UE determines the DSR triggering condition based on the first PDU in that PDU set. For example, for an LCG, the UE triggers a DSR once the remaining time of the first PDU in that PDU set is lower than the NW-configured threshold for that LCG.

[0167] Optionally, once PDU set-based operation is enabled, the reported remaining time of a PDU set in the DSR procedure equals or derives by the remaining time of the discardTimer associated with the first SDU of this PDU set.

[0168] For a PDU, its remaining time, or the remaining time of the PDU reported in the DSR process, is equal to the remaining time of the discardTimer associated with the first SDU of the PDU set, or related to the remaining time of the discardTimer associated with the first SDU of the PDU set.

[0169] Optionally, the multiple DSR information in the above embodiments, or the DSR data included on a MAC CE, or the number of DSRs reported for an LCH or an LCG, are determined by any of the following methods: pre-configured; predefined; indicated by RRC; determined by the UE; or a fixed value.

[0172] Optionally, the latency information can be either a latency threshold or a latency segment. For example, if the UE reports this latency information, it means that the UE has data packets with a latency less than the first threshold.

[0173] Optionally, the delay information can be a delay threshold, a delay segment, a delay index, a delay value, or delay information for different PDU sets of a burst of data. Optionally, it can be delay information for different PDU sets of the entire data packet of a burst of data, or delay information for a single PDU set of a burst of data.

[0174] Optional, latency information, which can be minimum latency information, or latency information corresponding to a PDU / PDU set that has not reported latency information.

[0175] Optionally, the latency information is information about the amount of data to be transmitted for the object corresponding to that latency (segment). Alternatively, it is information about all the data to be transmitted for the object.

[0176] Second, for a single LCG (object), or for a single LCH (object), the methods for reporting multiple latency information include: Optionally, the UE can report the latency information (multiple or all) of all PDUs / PDU sets / LCHs / LCGs in the current buffer.

[0177] Optionally, the UE can report the latency information (multiple or all) of all PDUs / PDU sets / LCHs / LCGs reported by the DSR configured in the current buffer.

[0178] Optionally, multiple delay information refers to information on multiple delay segments. For example, if a UE reports multiple delay segment information, it means that the UE has data to be transmitted that meets the requirements of these delay segments.

[0179] Optional, the delay information can be delay threshold information, delay segment information, delay index information, delay value information, or delay information for different PDU sets for one or more bursts.

[0180] Optional, latency information, which can be the few minimum latency information, or the latency information corresponding to a PDU / PDU set that has not reported latency information (optionally, the few minimum latency information).

[0181] Optionally, multiple delay information may be provided, which may be information on the amount of data to be transmitted for each reported delay (segment) for the object, or information on all the amounts of data to be transmitted for the object.

[0182] Optionally, multiple delay information items, N in number, may be pre-configured, pre-defined, or determined by RRC indication, or determined by the UE, or fixed. These delay information items may be delay value information, delay segment information, or delay index information, and may be pre-configured, pre-defined, or determined by RRC indication. If it is delay index or delay segment information, its range, maximum, or latest value may be pre-configured, pre-defined, or determined by RRC indication, or fixed.

[0183] The following exemplarily illustrates the delay information processing method in any of the above embodiments: For example, if LCG1 and LCG2 are configured to report DSR, and if LCG1 triggers DSR reporting (e.g., LCG1's latency is less than a first threshold), then within a first time period, LCG1's DSR information will not be triggered or reported, and / or the UE will report LCG1's latency information (one or more). Furthermore, the UE can report latency information for other LCGs (e.g., LCG2). Furthermore, the reported latency information may include corresponding data volume information.

[0184] For example, if LCG1 and LCG2 are configured to report DSR, and if LCG1 triggers DSR reporting (e.g., LCG1's latency is less than a first threshold), then within a first time period, no DSR information of the UE (including that of LCG1 and LCG2) will be triggered or reported, and / or the UE will report latency information of LCG1 (one or more). Furthermore, the UE can report latency information of other LCGs (e.g., LCG2). Furthermore, the reported latency information may include corresponding data volume information.

[0185] For example, if LCG1 and LCG2 are configured to report DSR, and if LCG1 has already triggered DSR reporting (e.g., LCG1's latency is less than the first threshold), and LCG2 triggers DSR reporting (furthermore, this may include a third reporting disable timer for LCG2 not running), the UE reports the latency information (one or more) of LCG2. Furthermore, the UE can report the latency information of other LCGs (e.g., LCG1's). Furthermore, the report may include corresponding data volume information.

[0186] For example, if LCG1 and LCG2 are configured to report DSR, and if LCG1 has already triggered DSR reporting (e.g., LCG1's latency is less than a first threshold), and LCG2 triggers DSR reporting (furthermore, this may include a third reporting disable timer not running for LCG2), and LCG2's DSR trigger threshold is different from LCG1's DSR trigger threshold (e.g., less than, or greater than) and / or LCG2's priority is higher than LCG1's priority, the UE reports the latency information of LCG2 (one or more). Furthermore, the UE can report the latency information of other LCGs (e.g., LCG1's). Furthermore, the report may include corresponding data volume information.

[0187] For example, for triggered DSRs, the UE only reports the DSR if the DSR reporting period is met, or only if the DSR reporting timer expires.

[0188] For example, for an LCG configured with DSR reporting, the UE reports a DS information. This DS information is used to inform the network that there are packets with latency less than a first threshold, or to inform the network of the latency range, latency index, or latency value of the packet with the lowest latency in the LCG. Alternatively, the DS information can indicate the amount of data for that latency.

[0189] For example, for an LCG configured with DSR reporting, the UE reports multiple DS information entries. These DS information entries are used to inform the network that packets exist within different delay ranges or indices, or to indicate which delay ranges or indices the packets within the LCG fall into. Alternatively, the DS information can indicate the data volume of packets with corresponding delays. For instance, the UE reports three delay information entries for LCG1, corresponding to three delay time periods (starting from the shortest delay or the beginning of the delay period), and reports the data volume information for each delay entry.

[0190] For example, Method 1: Only one remaining time information is reported for the associated LCG. The remaining time is the shortest value of the remaining times of the PDU sets in the associated LCG. Method 2: Multiple remaining time information is reported for the associated LCG. Each remaining time information is associated with an individual PDU set which is buffered in the associated LCG. ... Method 3: Multiple remaining time information is reported for the associated LCG. Each remaining time information is associated with an individual delay range in which the delay of available data of this LCG is distributed. The number, as well as the min / max value of the delay range, is fixed or configured.

[0191] In conclusion, compared to Alternative 2, Alternative 1 / 3 is preferred due to the controlled signaling overhead in one reporting. In addition, to avoid frequent DSR triggering / reporting of a specific LCG, we propose introducing a per-LCG DSR prohibit timer, that is, when the prohibit timer for a LCG is running, the UE does not trigger / report the DSR for this LCG. With this proposal, Alternative 3 is preferred because, in addition to the most urgent requirement, Alternative 3 contains enough delay information to let the gNB know the delay status of that LCG.

[0192] For example, Solution 1: Only one DS info is reported for the associated LCG. The DS info is associated with the shortest value of the remaining times in the LCG. Solution 2: More than one DS info is reported for the associated LCG. Solution 2-1: Each DS info is associated with an individual PDU / PDU set which is buffered in the LCG. Solution 2-2: Several delay ranges are designed for the delay status report, which covers the time distribution of all PDU / PDU sets in an LCG. Each DS info represents an individual delay range. Each DS message represents a separate delay range.Compared to other solutions, Solution 2-1 may have the issue of uncontrolled signaling overhead. Since multiple PDU / PDU sets in an LCG may arrive one by one, several DSRs will be triggered in a short period, inevitably leading to frequent DSR triggering and reporting. To address this, a per-LCG DSR prohibit timer could be considered. Accordingly, the UE would not trigger or report a DSR for a specific LCG if its DSR prohibit timer is running. Based on this assumption, Solution 2-2 is preferred. Besides reporting, which is the most urgent requirement, Solution 2-2 contains sufficient delay information to inform the gNB about the delay status of that LCG. Therefore, if the UE's DSR disable timer is running, the UE will not trigger or report the DSR for a specific LCG. Based on the above assumptions, Solution 2-2 is preferred because, in addition to reporting the most urgent needs, Solution 2-2 contains sufficient delay information to allow the gNB to know the delay status of the LCG.In the MAC CE for DSR, more than one DS information is reported for the associated LCG. Each DS information represents an individual delay range.

[0193] For example, a MAC CE containing DSR includes one or more delay information, each delay information corresponding to a delay range, and / or, corresponding data volume information (such as the data volume corresponding to this delay value or delay index or delay range).

[0194] Any of the above embodiments can reduce the DSR reporting load, and any of the above embodiments can be used in combination with other embodiments or used alone.

[0195] In one embodiment, such as Figure 3 As shown, another delay information processing method is also provided, namely the processing method under congestion control, which is applied to... Figure 1 Taking the user terminal (UE) side as an example, the explanation includes the following steps: S301, In the event of congestion or receipt of the first information, or if the first information indicates specific content or a specific value, the UE performs a first action. The first action includes at least one of the following: enabling packet loss processing for PDU sets; enabling packet loss processing for PSI; enabling congestion processing; using a specific packet loss timer or timer duration; determining important or unimportant PDU sets; determining the threshold or criteria for determining important or unimportant PDU sets; deactivating the DRS reporting function, or the DSR mechanism; stopping the DSR reporting or triggering function, or not reporting DSR information; deconfiguring DSR triggering or reporting.

[0196] The instructions can be, for example, indicating, or the meaning of specific content or values, such as: enabling packet loss processing; enabling packet loss processing for PDU sets; enabling packet loss processing for PSI; enabling congestion processing; using a specific packet loss timer or timer duration; determining important or unimportant PDU sets; determining the threshold or criteria for determining important or unimportant PDU sets; deactivating DRS reporting function, or DSR mechanism; stopping DSR reporting or triggering function, or not reporting DSR information; configuring DSR triggering or reporting.

[0197] In this embodiment, when the network side informs the UE of congestion or sends first information to the UE, the UE can perform packet loss handling operations or non-reporting DSR operations under these circumstances. Specifically, packet loss handling operations can be implemented by enabling packet loss handling for PDU sets, enabling congestion handling, using a specific packet loss timer or timer duration, determining important or unimportant PDU sets, or determining thresholds or criteria for important or unimportant PDU sets. DSR reporting operations can be implemented by deactivating the DSR reporting function, or through the DSR mechanism, or by stopping DSR reporting or triggering functions, or by not reporting DSR information, or by configuring DSR triggering or reporting.

[0198] The latency information processing method described in this application can handle congestion and DSR (Delayed Source Reception) processing, thereby avoiding excessive DSR reporting under congestion conditions and reducing resource overhead.

[0199] Optionally, in the above embodiments, the UE performing at least one of the following operations—not triggering DSR, not reporting DSR, stopping DSR function, stopping DSR triggering or reporting, deconfiguring DSR mechanism, deconfiguring DSR triggering or reporting, deactivating DSR mechanism, and deactivating DSR triggering or reporting—includes at least one of the following: clearing triggered DSR information; stopping all timers corresponding to DSR information; deactivating the configured DSR reporting function, or stopping the unconfigured DSR reporting function, or stopping the triggering, reporting, and MAC CE generation functions; and clearing all DSR information.

[0200] In this embodiment, for DSRs that have been reported through PUSCH and MAC CE, the triggered DSR information can be cleared, thereby reducing resource consumption in the cache.

[0201] Optionally, the DSR information in the above embodiments is the DSR information of objects whose importance is lower than the first preset threshold, or the DSR information of objects judged to be unimportant, or the DSR information of objects whose priority is lower than the second preset threshold, or the DSR information of objects judged to be low priority; the objects include any one of PDU, PDU set, LCG, and LCH.

[0202] The importance of DSR information, whether DSR information is important, the first preset threshold, the second preset threshold, and the priority of DSR information can be preconfigured, predefined, or given by Radio Resource Control (RRC) signaling. In this embodiment, the UE can compare the importance of DSR information and select the DSR information of objects with an importance lower than the first preset threshold as the DSR information for which the DSR reporting operation is not performed; optionally, the UE can determine whether the DSR information is important and use the unimportant DSR information as the DSR information for which the DSR reporting operation is not performed; optionally, the UE can compare the priority of DSR information and use the DSR information with a priority lower than the second preset threshold as the DSR information for which the DSR reporting operation is not performed; optionally, the UE can directly use the low-priority DSR information as the DSR information for which the DSR reporting operation is not performed. The above operations can be performed on the DSR information of different objects, such as any one of PDU, PDU set, LCG, and LCH.

[0203] This embodiment processes specific DSR information based on its importance and priority, thereby reducing resource overhead while ensuring effective data transmission.

[0204] Optionally, the importance or priority in the above embodiments can be determined by any of the following methods: determined by the UE; determined based on a threshold issued by the network; the priority of the LCH or LCG; the threshold determined by the UE; the characteristic information of the first object; the indication information of the network; the identifier of the LCG or LCH.

[0205] Furthermore, the threshold, identifier, priority, or first object feature in the above embodiments is determined by any of the following methods: pre-configured; RRC configured; network indicated; configured in the first information; determined by the UE.

[0206] In one embodiment, Figure 3 The aforementioned delay processing method further includes: During Logical Channel Prioritization (LCP), the priority of the MAC CE corresponding to the DSR is set to be lower than the priority of the data, or the priority of the MAC CE corresponding to the DSR is set to be the lowest during LCP.

[0207] In this embodiment, during the LCP process, the UE can set the priority of the MAC CE corresponding to the DSR of all objects to be lower than the priority of the data, or during the LCP process, the UE can set the priority of the MAC CE corresponding to the DSR of all objects to be the lowest. Optionally, during the LCP process, the UE can also set the priority of the MAC CE corresponding to the DSR of some objects to be lower than the priority of the data, or during the LCP process, the UE can set the priority of the MAC CE corresponding to the DSR of some objects to be the lowest.

[0208] Furthermore, the above methods also include: During LCP, the priority of the MAC CE corresponding to the DSR of a specific object is set to be lower than the priority of the data, or the priority of the MAC CE corresponding to the DSR of a specific object is set to be the lowest during LCP.

[0209] The specific object includes any one of a specific PDU, PDU set, LCG, or LCH; or, the specific object includes any one of a low-priority or unimportant PDU, PDU set, LCG, or LCH; or, the specific object includes any one of a low-priority PDU, PDU set, LCG, or LCH with a priority below the first threshold; or, the specific object includes any one of a PDU, PDU set, LCG, or LCH with an importance below the second threshold.

[0210] In one embodiment, when the UE performs the first action, it may also specifically perform the following: The DSR message can be triggered but not reported; or, for a specific object, the DSR message can be triggered but not reported. The specific object includes any one of a specific PDU, PDU set, LCG, or LCH; or, the specific object includes any one of a low-priority or unimportant PDU, PDU set, LCG, or LCH; or, the specific object includes any one of a low-priority PDU, PDU set, LCG, or LCH with a priority below a first threshold; or, the specific object includes any one of a PDU, PDU set, LCG, or LCH with an importance below a second threshold.

[0211] In one embodiment, when the UE performs the first action, it may also specifically perform the following: DSR information is not triggered, or DSR information is not reported; or, for a specific object, DSR information is not triggered, or DSR information is not reported. The specific object includes any one of a specific PDU, PDU set, LCG, or LCH; or, the specific object includes any one of a low-priority or unimportant PDU, PDU set, LCG, or LCH.

[0212] In one embodiment, when the UE performs the first action, it may also specifically perform the following: DSR is not triggered due to the Packet Data Convergence Protocol (PDCP) packet drop timer timeout; or, DSR is not triggered based on latency being less than a first threshold; or, DSR information is not triggered based on the duration of the PDCP packet drop timer; or, for a specific object, DSR is not triggered due to the PDCP drop timer timeout; or, DSR is not triggered based on latency being less than a first threshold; or, DSR information is not triggered based on the duration of the PDCP packet drop timer. Alternatively, DSR may not be reported due to PDCP packet loss timer timeout; or, DSR may not be reported based on latency being less than the first threshold; or, DSR information may not be reported based on the duration of the PDCP packet loss timer.

Alternatively, in congestion conditions or upon receiving the first information, the UE sets the reporting priority of the MAC CE corresponding to the DSR to a lower priority than data, or the lowest priority, during the LCP process. Alternatively, during the LCP process, the UE sets the reporting priority of the MAC CE corresponding to the DSR of a specific PDU / PDU set / LCG / LCH to a lower priority than data, or the lowest priority; or, in congestion conditions or upon receiving the first information, the UE triggers the DSR but does not report it.

Alternatively, the UE does not trigger or report the DSR for PDUs / PDU sets / LCGs / LCGs that it deems unimportant.

[0239] The first piece of information in the above example is: congestion indication information or indication information used by PSI-discard (such as including at least one of the following: enabling PSI-discard, indicating congestion, indicating the use of a specific discard timer or timer duration, network-indicated discard timer information, indication threshold information, indication threshold for judging important or unimportant PDU sets, deactivation / inapplicability / deconfiguration / suspend DSR).

[0246] Optionally, the first information can instruct the behavior of the DRB entity.

[0247] Method 1 can indicate information per DRB or UE behavior for a specific DRB. Optionally, it can carry a DRB identifier. Optionally, it can provide first information for this DRB, or instruct the UE to perform the operation corresponding to the first information.

[0248] For example, based on the aforementioned first information, the structure of the MAC CE containing that first information can be as follows: Figure 16 , Figure 17 , Figure 18 , Figure 19 , Figure 20 , Figure 21 and Figure 22 Any of the ones shown.

D represents at least one of the following: not using PSI-based discard or using PDUset-based discard, not using a specific timer or using an existing PDCP disard timer (or timer duration), not suspending or resuming DSR operation.

[0250] For example, in a DSR field: 1 means suspend the DSR operation. 0 means either not suspending or resuming the DSR operation. Alternatively, 0 means suspend the DSR operation. 1 means either not suspending or resuming the DSR operation.

[0251] For example, the timer index indicates which PDCP discard timer (or timer duration) is being used when multiple PDCP discard timers (or timer durations) are configured or pre-configured.

[0252] For example, TH represents the threshold for determining unimportant packets, and / or, using PSI-based discard. TH can be pre-configured, RRC-configured, or determined by the UE itself. For example, TH can have multiple configured or pre-configured values, and the TH index represents which value to use. For example, TH of 1 represents using PSI-based discard and / or threshold-based determination of unimportant packets, while 0 represents not using PSI-based discard and / or not using threshold-based determination of unimportant packets. For example, TH of 0 represents using PSI-based discard and / or threshold-based determination of unimportant packets, while 1 represents not using PSI-based discard and / or not using threshold-based determination of unimportant packets. Optionally, TH can sometimes also be a TH index.

[0257] For example, the timer index indicates which PDCP discard timer (or timer duration) is being used when multiple PDCP discard timers (or timer durations) are configured or pre-configured.

[0258] For example, TH represents the threshold for determining unimportant packets, and / or, using PSI-based discard. TH can be pre-configured, RRC-configured, or determined by the UE itself. For example, TH can be multiple configured or pre-configured values, and the TH index represents which value to use. For example, TH of 1 represents using PSI-based discard and / or threshold-based determination of unimportant packets, while 0 represents not using PSI-based discard and / or not using threshold-based determination of unimportant packets. For example, TH of 0 represents using PSI-based discard and / or threshold-based determination of unimportant packets, while 1 represents not using PSI-based discard and / or not using threshold-based determination of unimportant packets. Optionally, TH can sometimes also be the TH index. Method 3, in particular, can indicate information for all DRBs or corresponding UE actions. Optionally, it can carry a DRB identifier (e.g., assigning a DRB identifier. Correspondingly, the UE performs the operation corresponding to the first information for the DRB that indicates the DRB identifier. For example, assigning a DRB identifier and instructing the first information for this DRB / the operation of the first information for this DRB identifier). For example, assigning a DRB identifier and instructing all indicated DRB identifiers to perform the operation of the first information for this MAC CE), or the bitmap information of the DRB identifier (e.g., Di represents DRB i, and the corresponding bit of Di represents the first information for DRB i, such as: activation or PSI-based discard, or using a specific timer duration, and / or activating / suspending the DSR corresponding to DRB i. Optionally, if the content of the first information is one, the MAC CE can occupy 1 OCT; otherwise, it can occupy more than one OCT).

Optionally, the MAC CE occupies 1 OCT, or it can occupy more than one OCT).

[0267] Optionally, in any of the above embodiments, the first information may indicate 8 or 16 DSBs.

[0268] The above method is illustrated below by example: If the UE is configured to report DSR for LCG1 and 2, upon receiving the first message, the UE enables discard based on PSI (PDU set importance), cancels the triggered DSR for LCG1 / 2, and stops DSR triggering / reporting and related functions or operations.

[0269] If the UE is configured to report DSR for LCG1 and 2, and if the first message is received, and the first message indicates that DSR is stopped for LCG1 (or there is a change in DSR processing for LCG1), the UE enables discard based on PSI (PDU setimportance), and cancels the triggered DSR for LCG1, and stops DSR triggering / reporting and other related functions or operations.

[0270] The above embodiments provide DSR processing under congestion conditions. Each embodiment can be used in combination with other embodiments or used alone.

[0271] Optionally, the UE performs packet loss processing or PDU set processing in the first action, including: the PDCP layer instructs the lower layer to provide the Mth information, the lower layer including the RLC and / or MAC layers. The Mth information is used to indicate which PDUs or PDU sets or data packets correspond to the amount of data to be transmitted for DSR reporting, or to be carried in the MAC CE including the DSR, or to be the amount of data to be transmitted corresponding to the DSR, or to indicate which PDUs or PDU sets or data packets correspond to the timed-out or non-running PDCP discard timers, or to indicate that the amount of data corresponding to the PDUs or PDU sets or data packets corresponding to the timed-out or non-running PDCP discard timers is not used as the amount of data for BSR or DSR statistics or reporting.

[0272] In this embodiment, specifically, the packet loss handling or PDU set packet loss handling includes: the PDCP layer instructing the lower layers, including the RLC and / or MAC layers, to send information M. Information M is used to indicate which PDUs, PDU sets, or data packets correspond to the amount of data to be transmitted for DSR reporting; or, to indicate which PDUs, PDU sets, or data packets correspond to the amount of data to be transmitted for inclusion in the MAC CE including the DSR; or, to indicate which PDUs, PDU sets, or data packets correspond to the amount of data to be transmitted for the corresponding DSR; or, to indicate which PDUs, PDU sets, or data packets correspond to timed-out or non-running PDCP discard timers; or, to indicate that the data corresponding to the PDUs, PDU sets, or data packets corresponding to timed-out or non-running PDCP discard timers is not used as data for BSR or DSR statistics or reporting.

Optionally, the PDCP layer determines which PDUs, PDU sets, or data packets are based on importance, priority, etc.

[0275] Optionally, the UE performs the operation in the first action to determine or identify whether a data packet or PDU or PDU set is important or not, or whether it is prioritized or not, including: in the case of configuring packet loss processing or packet loss processing based on PDU set, and / or, upon receiving the first information, the UE determines or identifies whether a data packet or PDU or PDU set is important or not, or whether it is prioritized or not.

[0276] In this embodiment, specifically, when packet loss handling or PDU set-based packet loss handling is configured, and / or upon receiving the first information, the UE determines or identifies whether the data packet, PDU, or PDU set is important or has priority. For example, if the transmitting PDCP entity is configured with psi-BasedDiscard and the discardTimerXR is activated, upon receiving a PDCP SDU from upper layers, the transmitting PDCP entity shall identify whether the PDU set is a high-importance PDU set or a lower-importance PDU set.

[0300] The descriptions of A3, A4, and A5 in the above embodiments are as follows: As agreed before, Event A3, A4 and / or A5 can be configured as a CHOexecution condition for NES. The NES-specific configuration of Event A3 / 4 / 5would be the relaxed conditions to suit the NES scenario / requirement, thus,when the UE considers whether a candidate target cell is a triggered cell,the UE should consider both execution conditions together, i.e. the UEexecutes the CHO only if the source cell enters the NES and if any candidatetarget cell fulfils the NES-specific Event A3 / 4 / 5. Proposal 1: The UE consider a candidate target cell as a triggeredcell if the source cell enters the NES and if this candidate target cellfulfils the NES-specific Event A3 / 4 / 5. Once the legacy CHO execution event is fulfilled, the UE executes the legacy CHO no matter if the source cell enters the NES or not. Proposal 2: If both the legacy and NES-specific CHO executionconditions are configured and if the legacy CHO execution event is fulfilled, the UE should execute the legacy CHO. The above method is illustrated below by example: The first method is to use the common DCI to instruct the corresponding CHO to trigger the network energy saving (NES) function, or to determine whether the corresponding cell is in energy-saving mode or has entered energy-saving mode.

[0304] Optionally, the DCI instructs the UE to use, measure, or evaluate other CHO enforcement conditions (such as at least one of A3 / 4 / 5) corresponding to Network Energy Saving (NES).

[0305] The second method is to use MAC CE to instruct the corresponding CHO to trigger the Network Energy Saving (NES) function, or to execute the corresponding cell's energy saving or entry into energy saving mode.

[0306] The MAC CE is a UE-specific MAC CE, sent once for each UE. Alternatively, it can be a common MAC CE, where the same MAC CE is sent to all UEs.

[0307] Optionally, the MAC CE is a newly introduced MAC CE triggered for CHO execution.

[0308] Optionally, the MAC CE has a new LCID identifier, such as E-LCID. Accordingly, based on the LCID identifier, the UE determines the function of the MAC CE.

[0309] Optionally, the MAC CE carries indication information to indicate whether to trigger CHO execution.

[0310] Optionally, the indication information can be for a single cell, each cell, or a specific cell (e.g., for a cell bitmap, different bitmap positions indicate whether the cell corresponding to the bit should trigger CHO execution; or, for a cell index, indicate whether the cell at that cell index should trigger CHO execution). It can also be for the UE (correspondingly, indicating whether all serving cells of the UE, or Pcell / PScell, should execute CHO), or it can be for a MAC entity (correspondingly, indicating whether all serving cells of the UE's MAC entity, or the Pcell / PScell ​​corresponding to the MAC entity, should execute CHO).
