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

[0154] The following is a brief description of the relevant concepts mentioned in this application.

[0155] 1. Basic Concepts of eXtended Reality (XR)

[0156] The 3GPP 5G system introduces XR services, which are divided into the following categories:

[0157] Augmented Reality (AR): seamless integration of the real world and the virtual world, half real and half fake;

[0158] Virtual Reality (VR): It uses devices to simulate a virtual world, which is completely fake.

[0159] Mixed Reality (MR): contains both real physical entities and virtual information.

[0160] like Figure 2As shown, the XR service is modeled according to data frames. Each data frame can correspond to an XR video frame. The same data frame can be divided into one or more packet data unit sets (PDUset). A PDU set contains multiple packet data units (PDU). The PDUs in the PDU set are related and need to be processed uniformly. In this application, a data frame is also equivalent to a data burst.

[0161] Some of the features of XR services are as follows:

[0162] (1) The video frame period is 15 / 30 / 60 / 90 / 120fps (frames per second), and the corresponding period is 66.6 / 33.3 / 16.66 / / 11.11 / 8.33ms;

[0163] (2) The frame arrival time has unpredictable jitter;

[0164] (3) The latency requirement is 10ms or 7-15ms;

[0165] (4) Bit rate: 10-200Mbps;

[0166] (5) The PDU set QoS parameters include at least:

[0167] (i)PDU set error rate (PDU Set Error Rate, PSER);

[0168] (ii)PDU set delay budget (PSDB);

[0169] (iii) PDU-Set Integrated Handling Indication (PSIHI), which indicates whether the application layer should use all PDUs in the PDU set;

[0170] For uplink XR services, the 5G NR system introduces PDU discard and delay status report (DSR) mechanism.

[0171] 2. Basic concepts of PDU discard

[0172] Since PDU set has integrity requirements, when one or more PDUs in a PDU set times out or is discarded, the terminal needs to discard the entire PDU set, that is, discard other PDUs in the PDU set. Another case of PDU discarding is when the base station determines whether the network is congested. If the network is congested, the terminal can be instructed to discard some PDU sets that are not very important.

[0173] 3. Basic Concepts of DSR

[0174] The terminal can trigger and report an 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.

[0175] 4. Basic concepts of uplink cache reporting

[0176] 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.

[0177] 5. BSR triggering mechanism

[0178] There are three types of BSR: Regular BSR, Periodic BSR, and Padding BSR.

[0179] Regular BSR triggering: (1) Triggered when data with a higher priority than the data in the current buffer arrives or when data arrives in an empty buffer; (2) Triggered when the retxBSR-Timer times out and data arrives in the buffer.

[0180] Periodic BSR (Periodic BSR) triggering: If the periodicBSR-Timer times out, the PeriodicBSR is triggered.

[0181] 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.

[0182] A conventional BSR triggers a Scheduling Request (SR) report. After the SR is triggered, the triggered SR is canceled when the BSR that triggered the SR is sent or when the uplink resources can accommodate all uplink buffered data of the terminal.

[0183] 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 cancelled.

[0184] The following is an introduction to the embodiments of the present application in conjunction with the accompanying drawings. The processing method, device, terminal and network device of the cache status report provided in the embodiments of the present application can be applied to a wireless communication system. The wireless communication system can be a 5G communication system or a later 6G communication system. The technicians in the field can understand that the 5G NR system is only an example and is not a limitation.

[0185] In the prior art, the triggering and sending of BSR are independently operated. After the PDU discarding mechanism and DSR mechanism are introduced into the XR service, problems such as the data of the logical channel triggering BSR is discarded due to PDU discarding, and there is no need to report BSR MACCE, or the DSR report contains the amount of uplink buffer data related to the remaining time, and BSR MAC CE may cause redundant reporting, and the base station does not know how to allocate uplink scheduling resources. There is no technical solution to the above problems in the prior art.

[0186] The embodiments of the present application provide a method, apparatus, terminal and network equipment for processing a cache status report, so as to facilitate accurate resource allocation on the base station side, save uplink resources and improve transmission efficiency.

[0187] Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation methods of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0188] like Figure 3 As shown, an embodiment of the present application provides a method for reporting a cache status, which is executed by a terminal and includes:

[0248] Taking the network device as a base station as an example, the specific application examples of the embodiments of the present application are illustrated as follows.

[0249] Application Scenario 1: DSR Leads to BSR Cancellation

[0250] The execution steps on the terminal side include:

[0251] Step S501: The terminal triggers DSR and BSR simultaneously;

[0252] 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.

[0253] Step S502: The terminal receives an uplink scheduling command from the base station side, or determines a configured grant (CG) resource, and determines whether a DSR and / or BSR can be sent;

[0254] Step S503: If the DSR MAC CE includes the total buffered data volume of the terminal, or includes the total buffered data volume of the logical channel or logical channel group that triggers the BSR, the triggered BSR is canceled, and optionally, the SR corresponding to the triggered BSR is canceled.

[0255] Correspondingly, the execution steps on the base station side include:

[0256] Step S601: receiving a scheduling request SR sent by a terminal;

[0257] Optionally, the base station may determine that the SR is an SR corresponding to the DSR, or an SR corresponding to the BSR.

[0258] Step S602: allocating uplink resources to the terminal according to the SR;

[0259] Optionally, if it is determined that the terminal has pre-configured resources, the dynamically scheduled resources may not be sent.

[0260] Step S603: Receive the DSR MAC CE sent by the terminal, and allocate uplink resources to the terminal according to the buffer data included in the DSR MAC CE.

[0261] Application Scenario 2: Both DSR and BSR are reported

[0262] The execution steps on the terminal side include:

[0263] Step S701: The terminal triggers DSR and BSR simultaneously;

[0264] 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.

[0265] Step S702: The terminal receives an uplink scheduling command from the base station, or determines to configure authorized CG resources, and determines whether DSR and BSR can be sent simultaneously.

[0266] If DSR and BSR can be sent at the same time, a DSR MAC CE and a BSR MAC CE are included in the MAC PDU; if DSR and BSR cannot be sent at the same time, only DSR MAC CE is included in the MAC PDU, and BSR MAC CE is included in the subsequent uplink resources. Among them, BSR MAC CE includes all the buffered data of the terminal, or, includes the remaining data except the data included in DSR.

[0267] Correspondingly, the execution steps on the base station side include:

[0268] Step S801: receiving a scheduling request SR sent by a terminal;

[0269] Optionally, the base station may determine that the SR is an SR corresponding to the DSR, or an SR corresponding to the BSR.

[0270] Step S802: Allocate uplink resources to the terminal.

[0271] If it is determined that the terminal has pre-configured resources, the dynamically scheduled resources may not be sent.

[0272] 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.

[0273] Step S803: receiving the DSR MAC CE and BSR MAC CE sent by the terminal, determining 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 allocating uplink resources to the terminal.

[0274] Application Scenario 3: Impact of PDU Discard on Cache Status Reporting

[0275] The execution steps on the terminal side include:

[0276] Step S901: The terminal triggers DSR and / or BSR;

[0277] 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.

[0278] Step S902: The terminal triggers PDU set discard or PDU discard, including:

[0279] - Case 1: discard all data in the terminal buffer, or

[0280] - Case 2: discard all data in the logical channel or logical channel group that triggered the BSR, or

[0281] - Case 3: discarding all buffered data of the logical channel or logical channel group that triggered the DSR.

[0282] Step S903: For the above situation 1, cancel the triggered BSR, or send a BSRMAC 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 cached data volume of 0 to the network device.

[0283] Correspondingly, the execution steps on the base station side include:

[0284] Step S1001: receiving a scheduling request SR sent by a terminal, and allocating uplink resources to the terminal.

[0285] Step S1002: receiving uplink data sent by the terminal on the uplink resource, and if the terminal skips the uplink data transmission of the uplink resource, determining 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, determining 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, determining that there is no time-critical data to be sent.

[0286] Application Scenario 4: Impact of PDU Discard on Cache Status Reporting

[0287] The execution steps on the terminal side include:

[0288] Step S1101: The terminal triggers DSR and / or BSR;

[0289] 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.

[0290] Step S1102: the terminal triggers PDU set discard or PDU discard, including: discarding part of the data in the terminal buffer.

[0291] 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.

[0292] Correspondingly, the execution steps on the base station side include:

[0293] Step S1201: receiving a scheduling request SR sent by a terminal, and allocating uplink resources to the terminal.

[0294] 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 the DSR MAC CE.

[0295] Through the method for reporting cache status provided by the present application, when the terminal has reported part of the cache data volume, or part or all of the PDU or PDU set in the cache is 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.
