[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application No. 2023114594856, filed on November 3, 2023, entitled “A method, apparatus, terminal and network device for reporting cache status”, which is incorporated herein by reference in its entirety. Technical Field

[0003] The present disclosure relates to the field of communication technology, and in particular to a method, apparatus, terminal, and network device for reporting cache status. Background Art

[0004] Extended Reality (XR) and cloud gaming (CG), among the most important 5G media applications, require low latency, high throughput, and high reliability, requiring the transmission of large amounts of data in a short period of time. XR is a general term for different types of reality, encompassing all environments and human-computer interactions that combine real and virtual reality, generated by computer technology and devices. It encompasses representative forms such as augmented reality (AR), mixed reality (MR), and virtual reality (VR).

[0005] Currently, for uplink XR services, delay-based packet data unit (PDU) discarding mechanisms, congestion-based PDU discarding mechanisms, and delay reporting mechanisms have been introduced. These mechanisms will affect the terminal's reporting of the uplink buffer status. How to solve the impact of these mechanisms on the terminal's uplink buffer status reporting needs to be urgently addressed.

It should be noted that in the embodiments of the present disclosure, only a 5G base station is used as an example, but the specific type of base station 12 is not limited.

[0208] The following is a brief description of the relevant concepts mentioned in this disclosure.

[0209] 1. Basic Concepts of Extended Reality (XR)

[0210] The 3GPP 5G system introduces XR services, which are divided into the following categories:

[0211] Augmented Reality (AR): seamlessly integrates the real and virtual worlds, creating a half-real, half-fake experience.

[0212] Virtual Reality (VR): It uses devices to simulate a virtual world, which is completely fake.

[0213] Mixed Reality (MR): Contains both real physical entities and virtual information.

[0214] As shown in Figure 2, XR services are modeled as data frames. Each data frame corresponds to an XR video frame. The same data frame can be divided into one or more packet data unit sets (PDU sets). A PDU set contains multiple packet data units (PDUs). The PDUs within a PDU set are related and require unified processing. In this disclosure, a data frame is also equivalent to a data burst.

[0215] Some of the features of XR services are as follows:

[0216] (1) Video frame rates include 15 / 30 / 60 / 90 / 120fps (frames per second), corresponding to periods of 66.6 / 33.3 / 16.66 / / 11.11 / 8.33ms;

[0217] (2) Frame arrival time has unpredictable jitter;

[0218] (3) The latency requirement is 10ms or 7-15ms;

[0219] (4) Bit rate: 10-200Mbps;

[0220] (5) The PDU set QoS parameters include at least:

[0221] (i)PDU set error rate (PSER);

[0222] (ii)PDU set delay budget (PSDB);

[0223] (iii) PDU-Set Integrated Handling Indication (PSIHI), which indicates whether the application layer should use all PDUs in the PDU set;

[0224] For uplink XR services, the 5G NR system introduces PDU discard and Delay Status Report (DSR) mechanisms.

[0225] 2. Basic Concepts of PDU Discard

[0226] Because PDU sets require integrity, if one or more PDUs in a PDU set times out or is discarded, the terminal must discard the entire PDU set, effectively discarding all other PDUs in the set. Another possible PDU discard scenario is when the base station determines network congestion. If so, it can instruct the terminal to discard less important PDU sets.

[0227] 3. Basic Concepts of DSR

[0228] The terminal can trigger and report the uplink delay status report based on the time threshold configured on the base station side. The uplink delay status report is carried by the DSR MAC CE. The DSR MAC CE includes remaining time information and data volume information related to the remaining time information.

[0229] 4. Basic Concepts of Uplink Buffer Reporting

[0230] When the base station receives a buffer status report media access control element (Buffer Status Report MAC CE, BSR MAC CE) reported by the terminal, it can allocate uplink resources of corresponding size according to the BSR reported by the terminal.

[0231] 5. BSR triggering mechanism

[0232] There are three types of BSR: Regular BSR, Periodic BSR, and Padding BSR.

[0233] Regular BSR triggering: (1) Triggered when data with a higher priority than the data in the current buffer arrives or data arrives in an empty buffer; (2) Triggered when the retxBSR-Timer times out and data arrives in the buffer.

[0234] Periodic BSR (Periodic BSR) triggering: If the periodicBSR-Timer times out, the Periodic BSR is triggered.

[0235] Padding BSR triggering: If the UE can accommodate more bits (Padding) in addition to the data to be transmitted in the uplink grant (UL grant) when organizing the MAC PDU, the Padding BSR can be triggered.

[0236] A regular BSR triggers a Scheduling Request (SR) report. After an SR is triggered, the triggered SR is canceled when the BSR that triggered it is sent, or when the uplink resources can accommodate all the uplink buffered data of the terminal.

[0237] When the uplink resources can accommodate all uplink buffered data of the terminal, or when the uplink transmission includes the triggered BSR, the triggered BSR is canceled.

[0238] The following describes embodiments of the present disclosure in conjunction with the accompanying drawings. The buffer status report processing method, apparatus, terminal, and network device provided in the embodiments of the present disclosure can be applied to a wireless communication system. The wireless communication system can be a 5G communication system or a later 6G communication system. Those skilled in the art will appreciate that the 5G NR system is merely an example and not a limitation.

[0239] In related technologies, BSR triggering and sending are independent operations. The introduction of PDU discard and DSR mechanisms in XR services can lead to problems such as PDU discard causing the data on the logical channel that triggered the BSR to be discarded, eliminating the need to report a BSR MAC CE. Alternatively, DSR reports may include the amount of uplink buffered data related to the remaining time, potentially leading to redundant BSR MAC CE reports and the base station being unable to determine how to allocate uplink scheduling resources. There are no technical solutions to these problems in related technologies.

[0240] The embodiments of the present disclosure provide a method, apparatus, terminal, and network device for processing cache status reporting, so as to facilitate accurate resource allocation on the base station side, save uplink resources, and improve transmission efficiency.

[0291] As shown in FIG4 , an embodiment of the present disclosure provides a method for reporting a cache status, which is performed by a network device and includes:

[0300] receiving a triggered DSR and / or a triggered BSR sent by the terminal;

[0301] Receive an SR corresponding to the triggered DSR and / or an SR corresponding to the triggered BSR sent by the terminal.

[0302] Taking the network device as a base station as an example, the specific application of the embodiment of the present disclosure is illustrated below.

[0303] Application Scenario 1: DSR Leads to BSR Cancellation

[0304] The execution steps on the terminal side include:

[0305] Step S501: The terminal triggers DSR and BSR simultaneously;

[0306] Optionally, the SR corresponding to the BSR is triggered based on the triggered BSR and / or the SR corresponding to the DSR is triggered based on the triggered DSR.

[0307] Step S502: The terminal receives an uplink scheduling command from the base station, or determines configured grant (CG) resources, and determines whether a DSR and / or BSR can be sent.

[0308] Step S503: If the DSR MAC CE includes the total buffered data volume of the terminal, or the total buffered data volume of the logical channel or logical channel group that triggers the BSR, cancel the triggered BSR, and optionally cancel the SR corresponding to the triggered BSR.

[0309] Correspondingly, the execution steps on the base station side include:

[0310] Step S601: receiving a scheduling request SR sent by a terminal;

[0311] Optionally, the base station may determine that the SR is an SR corresponding to a DSR, or an SR corresponding to a BSR.

[0312] Step S602: Allocate uplink resources to the terminal according to the SR;

[0313] Optionally, if it is determined that the terminal has pre-configured resources, the dynamically scheduled resources may not be sent.

[0314] Step S603: Receive the DSR MAC CE sent by the terminal, and allocate uplink resources to the terminal according to the buffered data included in the DSR MAC CE.

[0315] Application Scenario 2: Both DSR and BSR are reported

[0316] The execution steps on the terminal side include:

[0317] Step S701: The terminal triggers DSR and BSR simultaneously;

[0318] Optionally, the SR corresponding to the BSR is triggered based on the triggered BSR and / or the SR corresponding to the DSR is triggered based on the triggered DSR.

[0319] Step S702: The terminal receives an uplink scheduling command from the base station side, or determines to configure authorized CG resources, and determines whether DSR and BSR can be sent simultaneously.

[0320] If the DSR and BSR can be sent simultaneously, the MAC PDU contains a DSR MAC CE and a BSR MAC CE. If the DSR and BSR cannot be sent simultaneously, the MAC PDU contains only the DSR MAC CE, and the BSR MAC CE is included on subsequent uplink resources. The BSR MAC CE contains the entire buffered data amount of the terminal, or the remaining data amount excluding the data amount included in the DSR.

[0321] Correspondingly, the execution steps on the base station side include:

[0322] Step S801: receiving a scheduling request SR sent by a terminal;

[0323] Optionally, the base station may determine that the SR is an SR corresponding to a DSR, or an SR corresponding to a BSR.

[0324] Step S802: Allocate uplink resources to the terminal.

[0325] If it is determined that the terminal has pre-configured resources, the dynamically scheduled resources may not be sent.

[0326] Optionally, if it is determined that both the DSR and the BSR need to be sent, uplink resources sufficient to accommodate the two MAC CEs are allocated to the terminal.

[0327] Step S803: Receive the DSR MAC CE and BSR MAC CE sent by the terminal, determine whether the BSR MAC CE contains the entire uplink buffered data amount or the remaining buffered data amount other than the data amount contained in the DSR MAC CE, and allocate uplink resources to the terminal.

[0328] Application Scenario 3: Impact of PDU Discard on Cache Status Reporting

[0329] The execution steps on the terminal side include:

[0330] Step S901: The terminal triggers DSR and / or BSR;

[0331] Optionally, the SR corresponding to the BSR is triggered based on the triggered BSR and / or the SR corresponding to the DSR is triggered based on the triggered DSR.

[0332] Step S902: The terminal triggers PDU set discard or PDU discard, including:

[0333] Case 1: discard all data in the terminal buffer, or

[0334] Case 2: discard all data in the logical channel or logical channel group that triggered the BSR, or

[0335] Case 3: All buffered data of the logical channel or logical channel group that triggers DSR is discarded.

[0336] Step S903: For the above situation 1, cancel the triggered BSR, or send a BSR MAC CE with a data volume of 0 to the network device; for the above situation 2, cancel the triggered BSR; for the above situation 3, cancel the triggered DSR; or send a DSR MAC CE with a remaining time of 0 and a buffered data volume of 0 to the network device.

[0337] Correspondingly, the execution steps on the base station side include:

[0338] Step S1001: receiving a scheduling request SR sent by a terminal and allocating uplink resources to the terminal.

[0339] Step S1002: Receive uplink data sent by the terminal on the uplink resource. If the terminal skips the uplink data transmission of the uplink resource, determine that the corresponding BSR and / or DSR is cancelled, or, if a BSR MAC CE with a cached data amount of 0 is received on the uplink resource, determine that the terminal has no uplink data to send, or, if a DSR MAC CE with a remaining time of 0 and a cached data amount of 0 is received on the uplink resource, determine that there is no time-critical data to be sent.

[0340] Application Scenario 4: Impact of PDU Discard on Cache Status Reporting

[0341] The execution steps on the terminal side include:

[0342] Step S1101: The terminal triggers DSR and / or BSR;

[0343] Optionally, the SR corresponding to the BSR is triggered based on the triggered BSR and / or the SR corresponding to the DSR is triggered based on the triggered DSR.

[0344] Step S1102: The terminal triggers PDU set discard or PDU discard, including discarding part of the data in the terminal buffer.

[0345] Step S1103: If a BSR MAC CE has been organized, update the content of the BSR MAC CE to include only the latest uplink data volume. Or, if a DSR MAC CE has been organized, update the content of the DSR MAC CE to include only the data volume in the cache that meets the DSR trigger condition and its corresponding remaining time value.

[0346] Correspondingly, the execution steps on the base station side include:

[0347] Step S1201: Receive a scheduling request SR sent by a terminal and allocate uplink resources to the terminal.

[0348] Step S1202: receiving terminal transmission on uplink resources, and allocating uplink resources to the terminal according to the amount of buffered data included in the BSR MAC CE and / or DSR MAC CE.

[0349] Through the method for reporting cache status provided by the present disclosure, when the terminal has reported part of the cache data volume, or part or all of the PDUs or PDU sets in the cache are discarded, the terminal can report an accurate BSR or DSR, or the terminal can clear or cancel the triggered BSR and its corresponding SR based on the cache, or the terminal can clear or cancel the triggered DSR and its corresponding SR based on the cache, or the terminal can update the information reported in the DSR MAC CE or BSR MAC CE. Canceling the BSR and / or DSR, as well as canceling the SR corresponding to the BSR and / or canceling the SR corresponding to the DSR, can save uplink air interface resources, facilitate accurate resource allocation on the base station side, and improve transmission efficiency.
