[0152] In some embodiments, the network device 102 may include an access network device and a core network device.

The access network device may include an evolved NodeB (eNB), a next generation evolved NodeB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved nodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, and at least one of an access node in a Wi-Fi system, but is not limited thereto.

[0155] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0156] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0157] In some embodiments, a core network device may be a device including one or more network elements, or may be multiple devices or device groups, each including all or part of the one or more network elements. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0158] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0159] The following embodiments of the present disclosure may be applied to the communication system 100 shown in Figure 1a, or a portion thereof, but are not limited thereto. The entities shown in Figure 1a are illustrative only. The communication system may include all or part of the entities shown in Figure 1a, or may include other entities other than those shown in Figure 1a. The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0160] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0161] In some embodiments, in XR services, data is usually composed of multiple streams (Qos flow), and its business volume is very large. The XR business flow needs to meet certain delay requirements during transmission, especially some data streams need to arrive at the server for decoding at the same time. The delay of any one of the data streams will cause the joint decoding of multiple data streams to fail. However, the network scheduling is dynamic, so in some cases, even if some data streams belong to low-priority logical channels, if some data packets have not been scheduled for a long time, it is necessary to send a buffer status report (BSR, Buffer Status Report) to notify the network as soon as possible. However, according to the relevant mechanism, BSR can only be sent when high-priority logical channel data arrives, which cannot meet the needs of emergency scheduling. Therefore, it is necessary to consider optimizing the emergency scheduling situation in XR.

[0162] In some embodiments, a DSR reporting feature is introduced. The basic idea is that a terminal can report a DSR, which carries delay information. For example, if uplink data is not scheduled for a long time, resulting in the remaining time of the data packet being less than a certain threshold. The remaining time of the data packet is the time until the packet is discarded, which is determined by the discard timer of the Packet Data Convergence Protocol (PDCP).

[0163] In some embodiments, a new separate Media Access Control (MAC) Control Element (CE) is defined for Delay State Report (DSR) (remaining delay and related data amount), for example, DSR reporting is not coupled with BSR reporting.

[0164] In some embodiments, threshold-based DSR reporting is supported. For example, DSR reporting is triggered when the remaining delay of a protocol data unit (PDU) or a PDU set is lower than a network-configured threshold, and the threshold is configured according to a logical channel group (LCG).

[0165] In some embodiments, a DSR MAC CE is defined, and the DSR reporting trigger is completely independent of the BSR. Threshold-based DSR is supported. This configuration is reported per LCG (Logical Channel Group). That is, if the terminal detects that the remaining delay of a data packet is lower than the threshold, it will trigger a DSR report.

[0166] In some embodiments, during the DSR reporting triggering process, if there is no authorization to send the DSR MAC CE, the SR will be triggered. However, it is not clear whether the DSR triggering is based on per LCG triggering or per LCH (logical channel) triggering.

[0167] FIG2a is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2a, the present disclosure embodiment relates to a communication method for a communication system 100, the method comprising:

[0168] Step S2101: The terminal sends first information to the network device.

[0169] In some embodiments, the network device receives first information sent by the terminal.

[0170] In some embodiments, the first information is used to indicate: a first time for delay status reporting DSR. It should be noted that DSR can also be called delay status report, which is not limited here.

[0171] In some embodiments, the first time is the time when the distance corresponding to the data packet to be transmitted is discarded.

[0172] In some embodiments, the first time is the time when the distance corresponding to the set of data packets to be transmitted is discarded.

[0173] In some embodiments, the set of data packets to be transmitted includes at least two data packets to be transmitted.

[0174] In some embodiments, the terminal determines that the data packet to be transmitted or the set of data packets to be transmitted is detected, and sends the first information to the network device based on the first time.

[0175] In some embodiments, upon detecting the data packet to be transmitted or the set of data packets to be transmitted, the terminal sends the first information to the network device based on the first time.

[0176] In some embodiments, the terminal determines that the first time is less than a time threshold, and sends the first information to the network device.

[0177] In some embodiments, when the first time is less than a time threshold, the first information is sent to the network device.

[0178] In some embodiments, the data packet to be transmitted is a data packet in a first logical channel.

[0179] In some embodiments, the data packet to be transmitted is a data packet in a logical channel included in a logical channel group, and the logical channel group includes at least two logical channels.

[0180] In some embodiments, the set of data packets to be transmitted is a set of data packets in a first logical channel.

[0181] In some embodiments, the set of data packets to be transmitted is a set of data packets in a logical channel included in a logical channel group, and the logical channel group includes at least two logical channels.

[0182] In some embodiments, the data packet to be transmitted is a data packet that has not been transmitted or a data packet for which DSR is performed.

[0183] In some embodiments, the data packet to be transmitted is a data packet in a logical channel included in the logical channel group or a set of data packets in a logical channel included in the logical channel group.

[0184] In some embodiments, the terminal determines that the data packet to be transmitted or the set of data packets to be transmitted is detected and there is no prepared but not executed (pending) DSR, and sends the first information to the network device based on the first time for the logical channel group.

[0185] In some embodiments, it is determined that uplink authorized resources meet the transmission of a first signaling, and the uplink authorized resources are used to send the first signaling to the network device for the logical channel group based on the first time; wherein the first signaling includes the first information.

[0186] In some embodiments, the terminal determines that the uplink authorized resources do not meet the transmission of the first signaling, and sends SR information based on the first scheduling request SR configuration parameter for the logical channel group; wherein the SR information includes the first information.

[0187] In some embodiments, the first SR configuration parameter is an SR configuration parameter associated with any logical channel in the logical channel group.

[0188] In some embodiments, the first SR configuration parameter is an SR configuration parameter associated with a logical channel in a logical channel group where the data packet to be transmitted or the set of data packets to be transmitted is detected.

[0189] In some embodiments, the first SR configuration parameter is not associated with a prepared but pending SR triggered by a DSR.

[0190] For example, for per LCG triggering:

[0191] In some embodiments, if the LCG is configured for Delay Status Reporting (DSR), the MAC entity shall:

[0192] 1> if the minimum remaining value of the PDCP discard timer for data buffered for the LCG that is not transmitted in any MAC PDU or reported as data amount in the DSR MAC CE becomes lower than the remaining time threshold remainingTimeThreshold for the LCG; and,

[0193] 1> If there is no DSR pending for the LCG since the last transmission of the DSR MAC CE:

[0194] 2>Trigger the DSR of LCG.

[0195] In some embodiments, if there is at least one DSR pending, the MAC entity shall:

[0196] 1> If uplink shared channel UL-SCH resources are available for new transmissions and as a result of logical channel priority, the UL-SCH resources can accommodate the DSR MAC CE and its subheader:

[0197] 2> Guide the multiplexing and assembly program to generate DSR MAC CE;

[0198] 1> Otherwise (either uplink shared channel (UL-SCH) resources are available for new transmissions and as a result of logical channel priority, the conditions for UL-SCH resources to accommodate the DSR MAC CE and its subheaders cannot be met, or the network is configured with a configuration grant but the network does not allow DSR reporting), then if there is no pending SR triggered by the DSR procedure for any logical channel of the LCG of the DSR:

[0199] 2>Trigger scheduling request.

[0200] In some embodiments, the data packet to be transmitted is a data packet in the first logical channel or a set of data packets in the first logical channel.

[0201] In some embodiments, the terminal determines that the data packet to be transmitted or the set of data packets to be transmitted is detected and there is no prepared but not executed (pending) DSR, and sends the first information to the network device based on the first time for the first logical channel or the logical channel group to which the first logical channel belongs.

[0202] In some embodiments, it is determined that the uplink authorization resources meet the transmission of the first signaling, and the uplink authorization resources are used to send the first signaling to the network device based on the first time for the first logical channel or the logical channel group to which the first logical channel belongs; wherein the first signaling includes the first information.

[0203] In some embodiments, the terminal determines that the uplink authorized resources do not meet the transmission of the first signaling, and sends SR information based on the first scheduling request SR configuration parameter for the first logical channel or the logical channel group to which the first logical channel belongs; wherein the SR information includes the first information.

[0204] In some embodiments, the first SR configuration parameter is an SR configuration parameter associated with a first logical channel where the data packet to be transmitted or the set of data packets to be transmitted is detected.

[0205] In some embodiments, the first SR configuration parameter is not associated with a prepared but pending SR triggered by a DSR.

[0206] In some embodiments, the terminal determines that the data packet to be transmitted or the set of data packets to be transmitted is detected on at least two logical channels, and sends a separate first information to the network device for each logical channel.

[0207] For example, for per LCH triggering:

[0208] In some embodiments, if the LCG is configured for delayed status reporting, the MAC entity shall:

[0209] 1> if the minimum remaining value of the PDCP discard timers (discardTimers) for data buffered for the LCG that is not transmitted in any MAC PDU or reported as data amount in the DSR MAC CE becomes below the remainingTimeThreshold on the LCH of the LCG; and,

[0210] 1> If there is no DSR pending for the LCH since the last transmission of the DSR MAC CE:

[0211] 2>Trigger the DSR of the LCH or trigger the DSR for the LCG to which the LCH belongs.

[0212] In some embodiments, if there is at least one DSR pending, the MAC entity shall:

[0213] 1> If UL-SCH resources are available for new transmissions and as a result of logical channel priority, the UL-SCH resources can accommodate the DSR MAC CE and its subheader:

[0214] 2> Guide the multiplexing and assembly program to generate DSR MAC CE;

[0215] 1> Otherwise (i.e., uplink shared channel UL-SCH resources are available for new transmissions, and as a result of logical channel priority, the conditions for UL-SCH resources to accommodate the DSR MAC CE and its subheader cannot be met, or the network has configured a configured grant but the network does not allow DSR reporting), if the same logical channel as this DSR has no pending SR triggered by the DSR procedure:

[0216] 2>Trigger scheduling request.

[0217] NOTE 1: When DSR triggering events occur on multiple logical channels simultaneously, each logical channel triggers a separate DSR.

[0218] Step S2102: The network device performs scheduling based on the first information.

[0301] b) When DSR is triggered, if there is uplink granted resource that can accommodate (or satisfy) the transmission of DSR MAC CE, then DSR MAC CE will be sent; otherwise (uplink shared channel UL-SCH resources may be available for new transmission, and as a result of logical channel priority, the conditions for UL-SCH resources to accommodate DSR MAC CE and its subheader cannot be met, or the network is configured with configuration grant but the network does not allow it to be used for DSR reporting), the first SR configuration will be used to initiate SR;

[0302] Among them, the first SR configuration can be the SR configuration associated with any logical channel in the logical channel group; (because the DSR trigger is for LCG, SR can be initiated using the SR configuration associated with any logical channel in the logical channel group); or the first SR configuration can be the SR configuration associated with the logical channel in which the first data is detected in the logical channel group.

[0303] In some embodiments, the first SR configuration may have no pending SR due to DSR triggering.

[0307] The first SR configuration may be an SR configuration associated with a logical channel that triggers DSR;

[0308] The first SR configuration may be an SR configuration associated with the logical channel and has no pending SR due to DSR triggering;
