It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0071] In the description of the embodiments of this application, the term "and / or" is simply a description of the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent the following three situations: A exists alone, A and B exist simultaneously, and B exists alone.

For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; internal connections between two components or interactions between two components. Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present application based on specific circumstances.

[0075] Currently, driven by the increasing demand for speed, latency, high-speed mobility, and energy efficiency, coupled with the increasing diversity and complexity of future services, the 3GPP international standards organization has begun developing 5G. The main application scenarios for 5G are: enhanced mobile ultra-broadband (eMBB), ultra-reliable low-latency communications (URLLC), and massive machine-type communications (mMTC). eMBB continues to focus on providing users with multimedia content, services, and data, and demand for it is growing rapidly. However, since eMBB can be deployed in diverse scenarios, such as indoors, in urban areas, and in rural areas, its capabilities and requirements vary significantly, making a generalized approach difficult and requiring detailed analysis based on specific deployment scenarios. Typical applications of URLLC include industrial automation, power automation, remote medical operations (surgery), and traffic safety. mMTC's key characteristics include high connection density, low data volumes, latency-insensitive services, low module costs, and long module lifespans. The new radio access network (NR) can also be deployed independently. To reduce air interface signaling and quickly restore radio connections and data services in 5G networks, a new Radio Resource Control (RRC) state, the RRC_INACTIVE state, is defined. This state is distinct from the RRC_IDLE and RRC_ACTIVE states. RRC_IDLE indicates UE-based cell selection and reselection, paging is initiated by the CN, and the paging area is configured by the CN. No UE AS context exists on the base station side. No RRC connection exists. RRC_CONNECTED indicates an RRC connection exists, and a UE AS context exists between the base station and the UE. The network knows the UE's location at the cell level. Mobility is network-controlled. Unicast data can be transmitted between the UE and the base station. RRC_INACTIVE indicates UE-based cell selection and reselection, a CN-NR connection exists, a UE AS context exists on a base station, paging is triggered by the RAN, and the RAN-based paging area is managed by the RAN. The network knows the UE's location at the RAN paging area level.

[0076] The eNodeB can allocate downlink or uplink wireless resources to each UE based on the downlink buffer data in the eNodeB and the buffer status report (BSR) received from the UE. That is, in the 5G NR BSR process, the UE uses the BSR to inform the serving base station of the amount of uplink buffer data of the UE, so that the base station can schedule the UE according to the data volume information provided by the UE. In order to save BSR reporting overhead, group reporting is adopted. Each uplink logical channel corresponds to a logical channel group (LCG), and multiple uplink logical channels can correspond to the same LCG. The correspondence between the logical channel LC and the LCG is configured by the network RRC. The UE reports the BSR based on the LCG. Each UE in NR can support up to 8 LCGs. The BSR triggering conditions are as follows: 1. Uplink data arrives on a higher-priority logical channel of the UE, in which case a regular BSR is triggered. 2. The padding portion of the uplink resources allocated to the UE after carrying other uplink data can carry a BSR MAC CE, in which case a padding BSR is issued. 3. The retransmission BSR timer retxBSR-Timer expires, and at least one uplink logical channel currently has uplink data to send, in which case a regular BSR is triggered. 4. The periodic BSR timer periodicBSR-Timer expires, in which case a periodic BSR is triggered. If multiple logical channels trigger regular BSRs simultaneously, each of these logical channels triggers a separate regular BSR. BSRs can be carried via a BSR MAC CE. If a terminal triggers a regular BSR but has no uplink resources to transmit new data or the uplink resources allocated to it cannot carry the data of the uplink logical channel that triggered the regular BSR, the terminal triggers an uplink Scheduling Request (SR).

[0077] At the 3GPP RAN#88e meeting, a research project titled "eXtended Reality (XR) and cloud gaming (CG) evaluations for NR" was approved. This project addresses services such as augmented reality (AR), virtual reality (VR), and cloud gaming. A key XR / CG service is video streaming, with arrival rates (measured in frames per second) of 30, 60, 90, and 120 fps. The corresponding video stream periods are {33.33ms, 16.67ms, 11.11ms, and 8.33ms}. XR data features variable packet sizes with a large average. For example, for an AR / VR data rate of 100Mbps, the average uplink packet size is 20,833 bytes, the maximum is 31,250 bytes, and the minimum is 10,417 bytes. That is, the size of the data packet to be transmitted in each cycle is between [10417 bytes and 31250 bytes]. In a real system with 100M bandwidth, transmitting a 20833-byte data packet requires approximately 4 time slots of transmission resources.

[0078] In 3GPP RAN2#120, RAN2 determined the reporting of delay information associated with data volume. This report describes the introduction of data volume information associated with delay information (e.g., remaining time) in the MAC CE. Further research is underway on FFS, including whether this will be an extended BSR or a new format. The details include how this will be implemented (e.g., what will be reported specifically) and how this information will be kept up to date, for example, taking into account UL scheduling delays.

[0079] In 3GPP RAN2#122, RAN2 determines the remaining time as derived from the Packet Data Convergence Protocol (PDCP) discard timer value. The UE calculates the remaining time based on the PDCP discard timer value. If the UE reports one or more values, it is FFS. How FFS is modeled in the PDCP specification? The UE supports FFS.

[0080] In 3GPP RAN2#123, further agreement was reached on delay status reporting (DSR), where 1) the network can configure whether the UE triggers delay status reporting. Further study of FFS is required if there are some thresholds for each LCG. 2) When the UE triggers reporting of delay information for an LCG, 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 study of FFS is required if this extends the BSR MAC CE or is a new MAC CE. 3) Assumption: a new separate MAC CE is defined for DSR (remaining delay and associated data volume) reporting, for example, DSR reporting is not coupled with BSR reporting. The detailed definition of associated data volume is further studied in FFS. 4) Threshold-based DSR reporting is supported, for example, DSR reporting is triggered when the remaining delay of a Packet Data Unit (PDU) PDU / PDU set is lower than a threshold configured by the NW. The threshold is configured per LCG. Whether FFS supports configuring multiple thresholds for an LCG. The remaining time is defined as FFS.

[0081] The Delay Status Report (DSR) procedure is used to provide the serving gNB with the delay status of UL data. 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 of the Physical Uplink Control Channel (PUSCH) transmission for which the DSR is sent (as specified in clause 7.3 of TS 38.323 [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 parameters: The remaining time threshold of the UL data configured to trigger DSR for the LCG. When the remaining time of the PDU in the LCG (if configured for DSR) is shorter than its associated remaining time threshold, the MAC entity triggers the DSR. It may also be updated after further agreement is reached, for example, a more precise definition of the "amount of data associated with the reported remaining time" is needed. The definition of the FFS remaining time is under further study. If the LCG reports one or more values, then FFS is under further study. If the data reported with delay below the threshold is FFS. However, the details of how the UE reports the DSR are still unclear. An embodiment of the present application provides a method for processing delay information to solve this problem.

[0082] The delay information processing method provided in the embodiment of the present application can be applied to the application scenario shown in Figure 1. As shown in Figure 1, the scenario includes network 01 and network 02, and network 01 and network 02 can be different types of networks; the scenario also includes base station 03, base station 04, base station 05, base station 06, base station 07 and base station 08, wherein base station 04, base station 06 and base station 07 can be macro base stations, and base station 03, base station 05, base station 08 can be micro base stations, wherein each base station can communicate data through network 01, and can also communicate data through network 02. The scenario also includes UE09, UE010, UE011, UE012, and UE013, and each UE can communicate with the base station through the network. As shown in Figure 1, the scenario includes a large number of transmission and reception points, and multiple transmission and reception points can constitute a virtual cell, and the virtual cell can serve one or more UEs. Among them, the transmission receiving point can be a network-side device or a terminal device. The network-side device can include a macro base station, a micro base station, etc., and can also include a core network device, such as a Mobility Management Entity (MME), a Serving GateWay (S-GW), etc., which is not limited in the embodiments of this application. It should be noted that Figure 1 in the embodiments of this application is only an example of a network architecture and does not constitute a limitation on the application scenarios of the embodiments of this application.

[0083] A UE can be a wireless terminal, which can be a device that provides voice and / or other service data connectivity to a user, or a handheld device with wireless connection capabilities, or other processing devices connected to a wireless modem. A wireless terminal can communicate with one or more core networks via a Radio Access Network (RAN).

For example, it can be a portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted mobile device that exchanges voice and / or data with the radio access network. A wireless terminal can also be called 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 another example, UEs may include, but are not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices may include smart speakers, smart TVs, smart air conditioners, smart car devices, etc. Portable wearable devices may include smart watches, smart bracelets, head-mounted devices, etc., and are not limited in the embodiments of this application.

[0084] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0085] In one embodiment, as shown in FIG2 , a method for processing delay information is provided. The method is described by taking the method applied to the user terminal UE side in FIG1 as an example, including the following steps:

[0086] S201: Under the first condition, trigger DSR and / or report DSR.

[0087] The first condition may be a condition for avoiding excessive DSR reporting, which may be preconfigured, predefined, or determined by RRC. Optionally, the first condition may include a preset period, i.e., when the preset period is met, DSR is triggered; or, when the preset period is met, DSR is reported; or, when the preset period is met, DSR is triggered and DSR is reported. Optionally, the first condition may further include other conditions.

[0088] In an embodiment of the present application, when the UE pre-transmits uplink data, it can determine whether the first condition is met. If so, DSR can be triggered; optionally, if it is met, DSR can be reported if there are transmission resources; optionally, if it is met, DSR can be triggered first, and the triggered DSR can be reported if there are transmission resources; if it is not met, the UE may not trigger and / or report DSR, or may trigger an uplink scheduling request SR.

[0089] The latency information processing method described in the embodiments of this application provides a method for implementing DSR reporting by a UE, namely, triggering and / or reporting a DSR under a first condition. Furthermore, by limiting the DSR reporting conditions, excessive DSR reporting can be avoided, thereby reducing the DSR reporting load.

[0090] In one embodiment, the first condition includes a DSR reporting period, that is, when executing S201, the following is specifically performed: triggering DSR and / or reporting DSR when the DSR reporting period is met.

[0091] The DSR reporting period is a reporting period set for a first object, where the first object may be any one of a UE, a MAC entity, an LCG, and an LCH. The DSR reporting period may be preconfigured or predefined or determined by RRC.

[0092] In an embodiment of the present application, when the UE pre-transmits uplink data, it can determine whether the DSR reporting period is met. If so, 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.

[0093] In one embodiment, the DSR reporting period includes a reporting timer, and / or the DSR is reported when the reporting timer times out.

[0094] In an embodiment of the present application, when the UE is pre-transmitting uplink data, it can determine whether the reporting timer has timed out, and report the DSR if it is determined to have timed out.

[0095] In one embodiment, the first condition includes a DSR triggering period, that is, when executing S201, specifically executing: triggering DSR and / or reporting DSR when the DSR triggering period is satisfied.

[0096] The DSR triggering period is a triggering period set for a first object, where the first object may be any one of a UE, a MAC entity, an LCG, and an LCH. The DSR triggering period may be preconfigured or predefined or determined by RRC.

[0097] In an embodiment of the present application, when the UE pre-transmits uplink data, it can determine whether the trigger timer has timed out, and trigger DSR if it is determined to have timed out.

[0098] In one embodiment, the DSR triggering period includes a triggering timer, and / or the DSR is triggered when the triggering timer times out.

[0099] In an embodiment of the present application, when the UE pre-transmits uplink data, it can determine whether the trigger timer has timed out, and trigger DSR if it is determined to have timed out.

[0100] It should be noted that the reporting timer and the triggering timer may be the same timer or different timers.

[0101] In summary of the above-mentioned related embodiments, the delay information processing method shown in FIG2 includes at least one of the following:

[0102] DSR is triggered only once in the DSR triggering cycle.

[0103] When the trigger timer times out, DSR can be triggered.

[0104] When DSR is triggered, the corresponding trigger timer is started.

[0105] The DSR is triggered only once.

[0106] When the reporting timer times out, a DSR can be reported.

[0107] When reporting DSR, start the corresponding reporting timer.

[0108] Furthermore, for the first object, DSR may be triggered only once in a DSR triggering period.

[0109] Furthermore, for the first object, when the trigger timer times out, a DSR may be triggered.

[0110] Furthermore, for the first object, when the trigger timer times out, a DSR may be triggered.

[0111] Furthermore, for the first object, when the DSR is triggered, a corresponding trigger timer may be started.

[0112] Furthermore, for the first object, DSR may be triggered only once in the DSR trigger report.

[0113] Furthermore, for the first object, when the reporting timer times out, a DSR may be reported.

[0114] Furthermore, for the first object, when reporting the DSR, a corresponding reporting timer may be started.

[0115] The first object may be any one of a UE, a Media Access Control (MAC) entity, a logical channel group (LCG), and a logical channel (LCH).

[0116] In one embodiment, the delay information processing method described in the embodiment of FIG2 further includes the following steps:

[0117] During the period when the first prohibit timer is running, the DSR is not triggered and / or the DSR is not reported.

[0118] In an embodiment of the present application, when the UE transmits uplink data, it may determine whether the first inhibit timer is running. If so, a DSR is not triggered; optionally, if so, no DSR may be reported; optionally, if so, no DSR may be triggered and no DSR may be reported. If it is determined that the first inhibit timer is not running, a DSR may be triggered and / or reported.

[0124] In one embodiment, the delay information processing method described in the embodiment of FIG2 further includes the following steps:

[0125] The triggered DSR is cleared when at least one of the following conditions is met:

[0126] 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; MAC PDU or PUSCH carrying DSR or DS information is transmitted or has been transmitted.

[0127] In the embodiment of the present application, the UE may report DSR information via PUSCH or MAC CE. Optionally, for triggered DSR information, when the DSR information is included in the PUSCH or MAC CE, that is, after the UE has reported the DSR information based on the PUSCH or MAC CE, the triggered DSR may be canceled.

[0128] In one embodiment, the delay information processing method described in the embodiment of FIG2 further includes any one of the following steps:

[0129] No DSR information is triggered for the first object that triggers or has triggered the DSR information.

[0130] For the first object that reports or has reported DSR information, DSR information is not triggered, or DSR is not reported.

[0131] The embodiments of the present application involve multiple methods for no longer triggering DSR information, as well as methods for no longer triggering and not reporting DSR, namely, including: no longer triggering DSR information for the first object that triggers DSR reporting; no longer triggering DSR information for the first object that has already triggered DSR information; no longer triggering DSR for the first object that reports DSR; no longer reporting DSR for the first object that reports DSR; no longer reporting DSR for the first object that reports DSR; and no longer reporting DSR for the first object that has already reported DSR.

[0132] Optionally, the first object in any of the above embodiments is any one of a UE, a MAC entity, an LCG, a LCH, a packet data unit (PDU), a data packet, a packet data unit set PDU set, and a data burst, or the first object is any one of a UE, a MAC entity, an LCG, a LCH, a PDU, a data packet, a PDU set, and a data burst configured with a DSR function or enabled with DSR.

[0133] The above method is illustrated by way of example:

[0134] For the DSR reporting function or DSR triggering function, an LCG or LCH that has already triggered DSR reporting will no longer trigger DSR reporting; or an LCG or LCH that has already reported DS information will no longer trigger DS information. Optionally, if any data in the above LCG or LCH is triggered, other data cannot be triggered or reported; if the same data in the above LCG or LCH is triggered, other data cannot be triggered or reported.

[0141] The delay of new data, PDU or PDU set is less than the threshold or within the first threshold range, and any of the new data, PDU, PDU set does not trigger DSR information and / or report DSR information, and meets the second condition.

[0142] In the above embodiment, the new data or PDU or PDU set belongs to the second object; optionally, the new data or PDU or PDU set belongs to the first object, wherein the second object includes any one of data, PDU, PDU set, LCG, LCH, MAC entity, and UE.

[0143] Furthermore, in the above embodiment, the DSR triggering or DSR reporting is triggered by the second object; optionally, the DSR triggering or DSR reporting is for the second object; the DSR triggering or DSR reporting is for the first object and the second object.

[0144] In the second condition in the above embodiment, several implementation methods are provided, that is, the second condition includes any one of the following: the delay of new data, PDU, PDU set, LCH, LCG, MAC entity or UE is less than the preset threshold, or falls within the first threshold range; the DSR prohibition timer of the new data, PDU, PDU set, LCH, LCG, MAC entity or UE is not running; the DSR reporting timer and / or trigger timer of the new data, PDU, PDU set, LCH, LCG, MAC entity or UE is not running; the new data, PDU, PDU set, LCH, LCG, MAC entity or UE reaches the DSR reporting period or trigger period.

[0149] In one embodiment, the delay information processing method described in the embodiment of FIG2 further includes the following steps:

[0150] When the third condition is met, DSR is not triggered and / or DSR is not reported for the data, PDU, PDU set, LCH, LCG, MAC entity or UE that has triggered DSR.

[0151] When the third condition is met, DSR is not triggered and / or DSR is not reported for data, PDU, PDU set, LCH, LCG, MAC entity or UE that has reported DSR.

[0152] Alternatively, if the third condition is met, for the data, PDU, PDU set, LCH, LCG, MAC entity or UE that has triggered DSR, if the fourth condition is met, DSR is not triggered and / or DSR is not reported.

[0153] Alternatively, if the third condition is met, for the data, PDU, PDU set, LCH, LCG, MAC entity or UE that has reported DSR, if the fourth condition is met, DSR is not triggered and / or DSR is not reported.

[0156] Alternatively, there is data, PDU, PDU set, LCH, LCG, MAC entity or UE for which DSR has been reported, and for the third object, DSR is not triggered and / or DSR is not reported.

[0159] Alternatively, when the third condition is met, there is data, PDU, PDU set, LCH, LCG, MAC entity or UE that has triggered DSR, and for the third object, DSR is not triggered and / or DSR is not reported.

[0160] Alternatively, when the third condition is met, there is data, PDU, PDU set, LCH, LCG, MAC entity or UE that has reported DSR, and for the third object, DSR is not triggered and / or DSR is not reported.

[0161] Alternatively, when the third condition is met, there is data, PDU, PDU set, LCH, LCG, MAC entity or UE that has triggered DSR. For the third object, when the fifth condition is met, DSR is not triggered and / or DSR is not reported.

[0162] Alternatively, when the third condition is met, there is data, PDU, PDU set, LCH, LCG, MAC entity or UE that has reported DSR. For the third object, when the fifth condition is met, DSR is not triggered and / or DSR is not reported.

[0163] The third object in the above embodiment includes any one of the following:

[0164] PDUs that have triggered and / or reported DSR;

[0165] The PDU set corresponding to the PDU that has triggered and / or reported DSR;

[0166] The data burst corresponding to the PDU that has triggered and / or reported DSR;

[0167] The LCH corresponding to the PDU that has triggered and / or reported DSR;

[0168] The LCG corresponding to the PDU that has triggered and / or reported DSR;

[0169] The MAC entity corresponding to the PDU that has triggered and / or reported the DSR;

[0170] UE corresponding to the PDU that has triggered and / or reported DSR;

[0171] The PDU set that has triggered and / or reported DSR;

[0172] The data burst corresponding to the PDU set that has triggered and / or reported DSR;

[0173] The LCH corresponding to the PDU set that has triggered and / or reported DSR;

[0174] The LCG corresponding to the PDU set that has triggered and / or reported DSR;

[0175] The MAC entity corresponding to the PDU set that has triggered and / or reported DSR;

[0176] UE corresponding to the PDU set that has triggered and / or reported DSR;

[0177] A data burst that has triggered and / or reported a DSR;

[0190] The MAC entity corresponding to the MAC entity that has triggered and / or reported the DSR;

[0191] UE that has triggered and / or reported DSR.

[0192] The above method is illustrated by way of example:

[0193] For an LCG, configuring DSR reporting is not possible. The data / PDU / PDU set that triggers a DSR cannot trigger a new DSR report. Alternatively, configuring DSR reporting is also possible for the UE, MAC entity, or LCH.

[0194] Optionally, for an LCG, the configuration can report DSR information. When 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, the configuration can report DSR. When new data / PDU / PDU set arrives, or there is new data / PDU / PDU set and the new data / PDU / PDU set has not triggered and / or reported DS information, and the third condition (the fourth condition or the 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 for UE, or MAC entity, or LCH to report DSR.

[0195] Optionally, for the DSR reporting function or the DSR triggering function, the LCG or LCH that has triggered the DSR report will no longer trigger the DSR report under the third condition (the fourth condition or the fifth condition), or the LCG or LCH that has reported the DSR information will no longer trigger or report the DSR information under the second condition.

[0196] In one embodiment, any one of the second condition, the third condition, the fourth condition, or the fifth condition in the above embodiments may include a duration and / or a threshold.

[0197] The duration represents the duration during which the DSR report has been triggered. Specifically, when executing step S210 above, the following steps are executed: an LCG or LCH that has triggered a DSR report will not trigger a DSR report again within the duration during which the DSR report has been triggered; or, when executing step S211 above, the following steps are executed: an LCG or LCH that has reported DSR information will not trigger or report DSR information again within the duration during which the DSR report has been triggered. Optionally, no new DSR triggering or reporting is allowed within the duration.

[0198] Among them, different thresholds may correspond to different objects. Optionally, different objects may correspond to the same threshold. When corresponding to different thresholds, new DSR triggering or reporting may be allowed. When corresponding to the same threshold, new DSR triggering or reporting is not allowed.

[0199] The above method is illustrated by way of example:

[0200] For the DSR reporting function or the DSR triggering function, a PDU or PDU set that has triggered DSR reporting no longer triggers DSR reporting, or a PDU or PDU set that has reported DRS information no longer triggers or reports DS information.

[0201] For the DSR reporting function or the DSR triggering function, the PDU or PDU set that has triggered the DSR reporting will no longer trigger the DSR reporting under the third condition (the fourth condition or the fifth condition), or the PDU or PDU set that has reported the DSR information will no longer trigger or report the DSR information under the third condition (the fourth condition or the fifth condition).

[0202] Based on the above embodiment, the above delay information processing method further includes:

[0203] If the first LCG has already triggered a DSR, then no DSR is triggered within the second time, or no DSR is triggered for the first LCG within the second time; or, no DSR is triggered, or no DSR is triggered for the first LCG within the second time. And / or, if the first LCG has already reported a DSR, then no DSR is reported within the second time, or no DSR is reported for the first LCG within the second time. Or, no DSR is reported, or no DSR is reported for the first LCG within the second time.

[0204] In an embodiment of the present application, if the first LCG has already triggered DSR information, then the DSR information is no longer triggered within the second time, or the DSR for the first LCG is not triggered within the second time; or, if the first LCG has already triggered DSR information, then the DSR is no longer triggered, or the DSR for the first LCG is not triggered within the second time. And / or, if the first LCG has already reported DSR information, then the DSR information is no longer reported within the second time, or the DSR for the first LCG is not reported within the second time; or, if the first LCG has already reported DSR information, then the DSR information is no longer reported, or the DSR for the first LCG is not reported within the second time.

And / or, if the first LCH or the first data or the first PDU in the first LCG has reported the DSR information, the DSR information is no longer reported, or, if the first LCH or the first data or the first PDU in the first LCG has reported the DSR information, the DSR for the first LCG is not reported, or, if the first LCH or the first data or the first PDU in the first LCG has reported the DSR information, the DSR information is no longer reported within the second time, or, if the first LCH or the first data or the first PDU in the first LCG has reported the DSR information, the DSR for the first LCG is not reported within the second time.

If 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.

And / or, if an LCG has triggered DSR reporting, and it is triggered by the first LCH or the PDU / PDU set in the first LCH, if the second LCH or the PDU / PDU set in the second LCH meets the DSR triggering condition, and the data priority of the second LCH is higher than the data priority of the first LCH, then the DSR for the second LCG can be triggered, or the DSR for the UE (the first LCG and the second LCG). Optionally, the DS information corresponding to the first LCH is reported or no longer reported.

[0244] If the first LCH in an LCG has triggered DSR reporting, no DSR reporting will be triggered within the second time (regardless of whether it is triggered by the first LCH or other LCHs). Alternatively, if an LCG has triggered DSR reporting, and it is triggered by the first LCH or the PDU / PDU set in the first LCH, such as the second LCH or the PDU / PDU set in the second LCH meets the DSR triggering condition, then DSR for the second LCH, or for the UE (the first LCG and the second LCG) can be triggered. Alternatively, if an LCG has triggered DSR reporting, and it is triggered by the first LCH or the PDU / PDU set in the first LCH, such as the second LCH or the PDU / PDU set in the second LCH meets the DSR triggering condition, and the DSR triggering threshold of the second LCH is lower than the DSR triggering threshold of the first LCH that triggered the LCG DSR, then DSR for the second LCH, or for the UE (the first LCG and the second LCG) can be triggered. And / or, if an LCG has triggered DSR reporting, and the DSR reporting is triggered by the first LCH or the PDU / PDU set in the first LCH, if the second LCH or the PDU / PDU set in the second LCH meets the DSR triggering condition, and the data priority of the second LCH is higher than the data priority of the first LCH, then the DSR for the second LCH, or for the UE (the first LCG and the second LCG) can be triggered. Optionally, the DS information corresponding to the first LCH is reported or no longer reported.

[0278] In one embodiment, when the DSR information is triggered, one of the following is included:

[0279] Any PDU in a PDU set can trigger a DSR message.

[0280] Alternatively, a specific PDU in a PDU set may trigger a DSR message.

[0281] Alternatively, if the reported DSR information is the DSR information of the PDU set, any PDU in the PDU set may trigger the DSR information.

[0282] Alternatively, if the reported DSR information is the DSR information of a PDU set, a specific PDU in the PDU set may trigger the DSR information.

[0283] The reported DSR information in the above embodiment is the DSR information of any one PDU in the PDU set; or, the reported DSR information is the DSR information of a specific PDU in the PDU set.

[0284] Optionally, the reported DSR information may include: reporting one or more DSR information for a sixth object; wherein the sixth object is LCG or LCH or PDU set or data burst or UE.

[0286] Optionally, the DSR information in the above embodiment includes any one of delay threshold information, delay segment information, delay index information, delay value information, and delay information for different PDU sets of burst data, or the DSR information corresponds to any one of delay threshold information, delay segment information, delay index, delay value, and delay information for different PDU sets of burst data.

[0287] Optionally, the DSR information in the above embodiment includes minimum delay information, or DSR information corresponding to a PDU or PDU set for which DSR information has not been reported.

[0288] 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 amounts of data to be transmitted for the sixth object.

[0289] Based on the above embodiment, a specific optional implementation is given:

[0290] If the reported delay is for a PDU set, then any PDU in the PDU set can trigger the delay report, or only a specific PDU can trigger the delay report (such as the first PDU). Alternatively, when reporting the delay information for a PDU set, the information can be the delay information for any PDU set or the delay information for a specific PDU set.

[0291] Optionally, Once PDU set based operation is enabled, the UE judges the DSR triggering condition based on the first PDU of that PDU set, i.e. for an LCG, the UE triggers a DSR once the remaining time of the first PDU of that PDU set in that LCG is lower than the NW configured threshold.

[0292] 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 discardTimer associated with the first SDU of this PDU set.

[0293] 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 is related to the remaining time of the discardTimer associated with the first SDU of the PDU set.

[0294] 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, is determined by any of the following methods: pre-configured; predefined; RRC indicated; UE determined; fixed value.

[0295] Optionally, the range, delay index, delay threshold, maximum value or minimum value of the first delay information in the DSR information in the above embodiment is determined by any of the following methods: pre-configured; pre-defined; RRC indicated; fixed value.

[0296] Based on the above embodiment, several specific optional implementation methods are given:

[0297] First, for an LCG (object), or for an LCH (object), the method of reporting a delay information includes:

[0298] Optionally, the UE may report a delay information of all PDUs / PDU sets / LCHs / LCGs in the current buffer, or report a delay information of all PDUs / PDU sets / LCHs / LCGs in the current buffer configured for DSR reporting.

[0299] Optionally, the delay information is information about a delay threshold or information about a delay segment. For example, the UE reports the delay information, which indicates that the UE has a data packet with a delay less than a first threshold.

[0300] Optionally, the delay information is a delay threshold information, or delay segment information, or delay index information, or delay value information, or delay information for different PDU sets of a burst data burst; optionally, it can be the delay information for different PDU sets of the entire data packet of a burst data burst, or it can be the delay information for a PDU set of a burst data burst.

[0301] Optionally, the delay information is the minimum delay information, or the delay information corresponding to the PDU / PDU set for which no delay information has been reported.

[0302] Optionally, the delay information is information about the amount of data to be transmitted corresponding to the delay (segment) for the object, or information about all amounts of data to be transmitted for the object.

[0303] Second, for an LCG (object), or for an LCH (object), the methods for reporting multiple delay information include:

[0304] Optionally, the UE may report the delay information of all PDUs / PDU sets / LCHs / LCGs in the current buffer (multiple or all).

[0305] Optionally, the UE may report the delay information (multiple or all) of all PDUs / PDU sets / LCHs / LCGs configured for DSR reporting in the current buffer.

[0306] Optionally, the multiple delay information is more than the delay segment information. For example, if the UE reports multiple delay segment information, it means that the UE has data to be transmitted that meets the delay segments in the reported delay segments.

[0307] Optionally, the delay information is delay threshold information, or delay segment information, or delay index information, or delay value information, or delay information for different PDU sets of one or more bursts.

[0308] Optionally, the delay information is the minimum delay information, or the delay information corresponding to the PDU / PDU set for which no delay information has been reported (optionally, the minimum delay information).

[0309] Optionally, the multiple delay information is information about the amount of data to be transmitted corresponding to each reported delay (segment) for the object, or information about all amounts of data to be transmitted for the object.

[0310] Optionally, multiple delay information items, the number N of which is preconfigured, predefined, or determined by RRC indication, or determined by the UE, or fixed. The delay information is delay value information, or delay segment information, or delay index information, which is preconfigured, predefined, or determined by RRC indication. If the delay index or delay segment information is delay index information, its range, maximum value, or latest value is preconfigured, predefined, determined by RRC indication, or fixed.

[0311] The following is an illustrative description of the delay information processing method in any of the above embodiments:

[0312] For example, if LCG1 and LCG2 are configured for DSR reporting. If LCG1 triggers DSR reporting (e.g., the latency of LCG1 is less than a first threshold), then within a first duration, DSR information of LCG1 is not triggered or reported, and / or the UE reports latency information (one or more) of LCG1. Furthermore, the UE may report latency information of other LCGs (e.g., LCG2). Furthermore, the report may include corresponding data volume information.

[0313] For example, if LCG1 and LCG2 are configured for DSR reporting. If LCG1 triggers DSR reporting (e.g., the delay of LCG1 is less than the first threshold), then within the first duration, the UE's DSR information (including that of LCG1 and LCG2) is not triggered or reported, and / or the UE reports the delay information (one or more) of LCG1. Furthermore, the UE can report the delay information of other LCGs (e.g., that of LCG2). Furthermore, the report can include corresponding data volume information.

[0314] For example, if LCG1 and LCG2 are configured for DSR reporting. If LCG1 has triggered DSR reporting (e.g., the latency of LCG1 is less than the first threshold), and LCG2 has triggered DSR reporting (further, this may include that the third reporting prohibition timer for LCG2 is not running), the UE reports the latency information (one or more) of LCG2. Furthermore, the UE may report the latency information of other LCGs (e.g., LCG1). Furthermore, the report may include corresponding data volume information.

[0315] For example, if LCG1 and LCG2 are configured for DSR reporting. If LCG1 has triggered DSR reporting (such as the delay of LCG1 is less than the first threshold), and LCG2 has triggered DSR reporting (further, it may include that the third reporting prohibition timer for LCG2 is not running), and the DSR triggering threshold of LCG2 is different from the DSR triggering threshold of LCG1 (such as less than, or greater than) and / or the priority of LCG2 is higher than the priority of LCG1, the UE reports the delay information (one or more) of LCG2. Further, the UE may report the delay information of other LCGs (such as LCG1). Further, the report may include corresponding data volume information.

[0316] For example, for a triggered DSR, the UE reports the DSR only when the DSR reporting period is met, or reports the DSR only when the DSR reporting timer expires.

[0317] For example, for an LCG configured for DSR reporting, the UE reports DS information. This DS information is used to inform the network of the presence of packets with a delay less than a first threshold, or to inform the network of the delay range, delay index, or delay value of the packet with the lowest delay in the LCG. Alternatively, the DS information may indicate the amount of data associated with the delay.

[0318] For example, for an LCG configured with DSR reporting, the UE reports multiple DS information. The DS information is used to inform the network of packets with delays within different ranges or indices, or to inform the network of which delay ranges or indices the packets in the LCG are within. Alternatively, the DS information indicates the data volume information of the packets corresponding to the delay. For example, the UE reports three delay information of LCG1, corresponding to three delay time periods (starting from the minimum delay or the beginning of the delay segment), and reports data volume information for different delay information.

[0319] For example, method 1: Only one remaining time info 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 info is reported for the associated LCG. Each remaining time info is associated with an individual PDU set which is buffered in the associated LCG. . . . . Method 3, Multiple remaining time info is reported for the associated LCG. Each remaining time info 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.

[0320] In summary, compared to Alt 2, Alt1 / 3 is preferred due to the controlled signalling overhead in one reporting. In addition, to avoid frequent DSR triggering / reporting of a specific LCG, we assume to introduce a per-LCG DSR prohibit timer, i.e., when the prohibit timer for a LCG is running, the UE does not trigger / report the DSR for this LCG. With this assumption, Alt 3 is preferred since, besides the most urgent requirement, Alt3 contains enough delay info to let the gNB know the delay status of that LCG。

[0321] 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 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. Solution 2-2: Several delay ranges are designed for delay status reporting, which covers the time distribution or time range of all PDUs / PDU sets in an LCG or LCG. Each DS information represents a separate delay range.Compared to other solutions, Solution 2-1 may have the uncontrolled signalling overhead issue. As multiple PDU / PDU sets in an LCG may arrive one-by-one, several DSRs would be triggered in a short time duration, which definitely induces frequent DSR triggering and reporting. To resolve such this issue, 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 the above assumption, Solution 2-2 is preferred since, besides the reporting of the most urgent requirement, Solution 2-2 contains enough delay information to let the gNB know the delay status of that LCG. Therefore, if the UE's DSR prohibit timer is running, the UE will not trigger or report 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 also contains sufficient delay information to allow the gNB to know the delay status of this LCG.In the MAC CE for DSR, more than one DS info is reported for the associated LCG. Each DS info represents an individual delay range.

[0322] For example, the MAC CE including the DSR includes one or more delay information, each delay information corresponds to a delay range, and / or corresponding data volume information (such as the data volume corresponding to the delay value or delay index or delay range).

[0323] Any of the above embodiments can achieve the effect of reducing the DSR reporting load, and any of the above embodiments can be used in combination with other embodiments or used alone.

[0324] In one embodiment, as shown in FIG3 , another method for processing delay information is provided, namely, a method for processing delay information under congestion control. This method is described by taking the method applied to the user terminal UE side in FIG1 as an example, and includes the following steps:

[0325] S301: In the event of congestion or receiving first information, or when 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 a PDU set; enabling packet loss processing for a PSI; enabling processing for congestion; using a specific packet loss timer or timer duration; determining whether a PDU set is important or unimportant; determining a threshold or criterion for determining whether a PDU set is important or unimportant; deactivating a DRS reporting function or a DSR mechanism; stopping a DSR reporting or triggering function, or not reporting DSR information; or deconfiguring DSR triggering or reporting.

[0326] The indications therein may, for example, indicate, or the meaning of the specific content or specific value thereof may, for example, be: for example, indicating: enabling packet loss processing; enabling packet loss processing for PDU set; enabling packet loss processing for PSI; enabling processing for congestion; using a specific packet loss timer or timer duration; determining an important or unimportant PDU set; determining a judgment threshold or criterion for an important or unimportant PDU set; deactivating the DRS reporting function, or the DSR mechanism; stopping the DSR reporting or triggering function, or not reporting DSR information; and configuring DSR triggering or reporting.

[0327] In an embodiment of the present application, when the network side informs the UE of congestion, or sends a first message to the UE, the UE can perform relevant operations of packet loss processing in this case, or perform relevant operations of not reporting DSR processing. Among them, the relevant operations of packet loss processing can be implemented specifically by enabling packet loss processing for PDU set, or by enabling processing for congestion, or by using a specific packet loss timer or timer duration, or by determining an important or unimportant PDU set to implement packet loss processing, or by determining a judgment threshold or criterion for an important or unimportant PDU set to implement packet loss processing. The relevant operations of reporting DSR processing can be implemented specifically by deactivating the DRS reporting function, or by the DSR mechanism, or by stopping the DSR reporting or triggering function, or by not reporting DSR information, or by deconfiguring DSR triggering or reporting.

[0328] The delay information processing method described in the embodiment of the present application can realize the processing under congestion conditions and the processing of DSR, so that excessive DSR reports can be avoided under congestion conditions, thereby achieving the effect of reducing resource overhead.

[0329] Optionally, in the above embodiment, the UE performs at least one of the operations of 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, including at least one of the following: clearing the triggered DSR information; stopping all timers corresponding to the DSR information; deactivating the configured DRS reporting function, or stopping the unconfigured DSR reporting function, or stopping triggering, reporting, and generating MAC CE functions; clearing all DSR information.

[0330] In this embodiment, for the DSR reported through the PUSCH and MAC CE, the triggered DSR information may be cleared, thereby reducing resource usage in the cache.

[0331] Optionally, the DSR information in the above embodiment is the DSR information of an object whose importance is lower than a first preset threshold, or the DSR information of an object judged to be unimportant, or the DSR information of an object whose priority is lower than a second preset threshold, or the DSR information of an object judged to be of low priority; the object includes any one of PDU, PDU set, LCG, and LCH.

[0332] Among them, 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 pre-configured, pre-defined or given by Radio Resource Control signaling (Radio Resource Control, RRC). In an embodiment of the present application, 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 performing the non-reporting DSR operation; optionally, the UE can determine whether the DSR information is important and use the unimportant DSR information as the DSR information for performing the non-reporting DSR operation; 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 performing the non-reporting DSR operation; optionally, the UE can directly use the low-priority DSR information as the DSR information for performing the non-reporting DSR operation. The above operations can be performed on the DSR information of different objects, for example, for any one of PDU, PDU set, LCG, and LCH.

[0333] This embodiment processes specific DSR information based on its importance, priority, etc., which can reduce resource overhead while ensuring effective data transmission.

[0334] Optionally, the importance or priority in the above embodiments is determined by any one of the following methods: UE determination; determination based on a threshold issued by the network; priority of LCH or LCG; threshold determined by UE; characteristic information of the first object; indication information of the network; identification of LCG or LCH.

[0520] The description of A3, A4 and A5 in the above embodiment is as follows:

[0521] As agreed before,Event A3,A4 and / or A5 can be configured as a CHO execution condition for NES.The NES-specific configuration of Event A3 / 4 / 5 would 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 UE executes the CHO only if the source cell enters the NES and if any candidate target cell fulfils the NES-specific Event A3 / 4 / 5.

[0522] Proposal 1:The UE consider a candidate target cell as a triggered cell if the source cell enters the NES and if this candidate target cell fulfils the NES-specific Event A3 / 4 / 5.

[0523] Before the source cell enters the NES, the UE may move out of the boundary of the source cell. If that is the case, the network needs to also configure the legacy CHO execution conditions to keep the UE connected and guarantee the UE's performance. 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.

[0524] Proposal 2: If both the legacy and NES-specific CHO execution conditions are configured and if the legacy CHO execution event is fulfilled, the UE should execute the legacy CHO.

[0525] The above method is exemplified below:

[0526] The first method is to use common DCI to indicate the CHO execution trigger corresponding to the network energy saving (NES), or to execute whether the corresponding cell saves energy or enters the energy saving state.

[0527] Optionally, the common DCI is a newly defined DCI, or an existing DCI used for activating / deactivating cell DTX / DRX is reused.

[0528] Optionally, a reserved bit in the DCI or a reused existing bit (for example, an existing bit indicates a different meaning in a specific situation) indicates whether to trigger CHO execution.

[0529] Optionally, whether to trigger CHO execution is indicated for each cell, or whether to trigger CHO execution is indicated for Pcell and / or PScell, or whether to trigger CHO execution is indicated for specific cells (for example, for which cell or cells).

[0530] Optionally, the DCI instructs the UE to use, measure, or evaluate other CHO execution conditions (such as at least one of A3 / 4 / 5) corresponding to network energy saving (NES).

[0531] The second method is to use MAC CE to indicate the CHO execution trigger corresponding to the Network Energy Saving (NES), or to execute whether the corresponding cell saves energy or enters the energy saving state.

[0532] The MAC CE is a UE-specific MAC CE, one of which is sent to each UE, or a common MAC CE, the same of which is sent to all UEs.

[0533] Optionally, the MAC CE is a newly introduced MAC CE triggered for CHO execution.

[0534] Optionally, the MAC CE has a new LCID identifier, such as E-LCID. Accordingly, based on the LCID identifier, the UE determines the role of the MAC CE.

[0535] Optionally, the MAC CE carries indication information for indicating whether to trigger CHO execution.

[0536] Optionally, the indication information is for a cell or each cell or a specific cell (for example, given a cell bitmap, different bitmap positions indicate whether the cell corresponding to the bit position triggers CHO execution. For another example, given a cellindex, the cell of this cell index indicates whether CHO execution is triggered), or it can be for the UE (correspondingly, indicating whether all service cells of the UE, or Pcell / PScell ​​execute CHO), or it can be for the MAC entity (correspondingly, indicating whether all service cells of this MAC entity of the UE, or Pcell / PScell ​​corresponding to this MAC entity execute CHO).

[0537] The MAC CE instructs the UE to use, measure, or evaluate other CHO execution conditions (such as at least one of A3 / 4 / 5) corresponding to network energy saving (NES).
