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.

[0188] 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).

[0189] 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.

[0190] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1a, or a portion thereof, but are not limited thereto. The entities shown in FIG1a are illustrative only. The communication system may include all or a portion of the entities shown in FIG1a, or may include other entities other than those shown in FIG1a. 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.

[0191] 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).

[0192] In some embodiments, in the Extended Reality (XR) service, data is usually composed of multiple Quality of Service (QoS) flows, and its business volume is very large. The XR business flow needs to meet certain latency 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 BSR to notify the network as soon as possible.

[0193] In some embodiments, a DSR reporting feature is introduced. The basic concept is as follows: a terminal can report a DSR containing 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).

[0194] In some embodiments, the Delay Status Report (DSR) procedure is used to provide the delay status of a Logical Channel Group (LCG) to the serving base station (gNB). The delay status for an LCG includes the remaining time, which is the minimum remaining value of the PDCP discard timer in the Service Data Unit (SDU) buffered by the LCG, and the total amount of delay-critical uplink (UL) data for the LCG, as determined by the data volume calculation process for the associated Radio Link Control (RLC) and PDCP entities, respectively.

[0195] In some embodiments, if the DSR is reported to the network, the base station knows that a specific logical channel needs to be scheduled in a timely manner. An uplink authorization needs to be sent to the terminal. However, according to the relevant LCP process, the uplink data is packaged strictly according to the priority level of the logical channel. Therefore, it is still very likely that when the UE obtains the uplink authorization, the logical channel whose remaining time is about to expire will not be able to be transmitted in time. In this way, the terminal will continue to report the DSR, resulting in unnecessary signaling overhead. Similarly, even in the same logical channel, non-urgent data will be scheduled first, so the logical channel whose remaining time is about to expire will not be able to be transmitted in time. Therefore, this needs to be optimized.

[0197] Step S2101: The terminal receives first information sent by the network device.

[0200] In some embodiments, the first policy may be a policy for the terminal to perform packetization upon detecting the first type of data. It should be noted that data in the present disclosure may also be referred to as a data packet, which is not limited herein.

[0201] In some embodiments, the first policy is used to indicate: first type of data to be transmitted is preferentially selected for data transmission.

[0202] In some embodiments, the first strategy is used to indicate that a first type of logical channel is preferably selected for data transmission.

[0203] In some embodiments, the first strategy is used to indicate: preferentially selecting the first type of data to be transmitted for data transmission and preferentially selecting the first type of logical channel for data transmission.

[0204] In some embodiments, the first strategy is used to indicate: priority transmission of the first type of data within the logical channel.

[0205] In some embodiments, the first policy is used to indicate: preferentially selecting the first type of logical channel from logical channels to perform data transmission.

[0206] In some embodiments, the first type of logical channel includes a first logical channel that detects the first type of data, a second logical channel that triggers the execution of a first operation, a logical channel in a logical channel group to which the first logical channel belongs, and / or a logical channel in a logical channel group to which the second logical channel belongs.

[0207] In some embodiments, the first operation is triggering a Delay Status Report (DSR).

[0208] In some embodiments, it may be a logical channel group that triggers the DSR.

[0209] In some embodiments, the first policy is used to indicate that the priority of the first type of logical channel is updated to the highest priority.

[0210] In some embodiments, the priority of the first type logical channel is updated to the highest priority. It should be noted that there may be multiple logical channels with the highest priority, and they are not limited to one or more of the first type logical channels. In addition to the first type logical channels, they may also be several of the second type logical channels. The second type logical channel may be a logical channel in which no first type data is detected, which is not limited here. In some embodiments, the logical channels include a third logical channel and a fourth logical channel; the first policy is used to indicate that the priority of data transmission on the third logical channel is higher than the priority of data transmission on the fourth logical channel.

[0211] In some embodiments, the third logical channel is the first type logical channel, and the fourth logical channel is a logical channel in which the first type data is not detected.

[0212] In some embodiments, the first type of logical channel includes at least two logical channels, and the first policy is used to indicate that the priorities of the at least two logical channels are determined based on the remaining time of the first type of data to be transmitted in the logical channels.

[0213] In some embodiments, the remaining time of the first type of data (or data packet) is the time from when the first type of data (or data packet) is discarded, and the remaining time can be determined based on a discard timer of the Packet Data Convergence Protocol (PDCP).

[0214] In some embodiments, the first type of data includes at least one of the following:

[0215] Data with predetermined scheduling requirements;

[0216] Data where the remaining time is less than or equal to a first threshold;

[0217] Data that fails to meet the synchronization requirements between at least two data streams.

[0218] In some embodiments, the first type of data may be data requiring urgent dispatch (delay critical data).

[0219] In some embodiments, the first type of data may be data whose scheduling has lagged behind and which cannot meet a multi-stream synchronization threshold between data streams.

[0225] Exemplarily, the MAC layer may determine, through inter-layer interaction, that the remaining time of the data packet is less than or equal to a threshold, thereby determining that the data is the first type of data.

[0226] In some embodiments, a medium access control (MAC) layer of the terminal receives the second information from a first protocol layer of the terminal.

[0230] Step S2104: The terminal allocates transmission resources.

[0231] In some embodiments, the terminal preferentially allocates transmission resources to the first type of data in the logical channel.

[0232] Exemplarily, when a logical channel is selected and resources are allocated, MAC will give priority to the transmission of the first type of data, or allocate resources to the first type of data first.

[0233] In some embodiments, the terminal allocates transmission resources to the logical channels based on the priority order of the logical channels.

[0234] In some embodiments, the logical channel comprises the first type logical channel.

[0235] In some embodiments, the terminal ignores priority bit rate (PBR) information and preferentially allocates transmission resources to the first type of data in the logical channel.

[0236] In some embodiments, when the logical channel is selected and resources are allocated, MAC will give priority to the transmission of the first type of data, or when resources are allocated to the first type of data first, it may not be subject to the priority bit rate (RBR, Prioritized Bit Rate) limit of the logical channel, and the data transmission of the first type of data can be met.

[0237] Step S2105: The terminal determines whether the first policy is effective or ineffective.

[0242] In some embodiments, the terminal determines that the first policy is effective.

[0243] In some embodiments, the terminal receives fourth information sent by the network device; wherein the fourth information is used to indicate that the first policy is effective.

[0244] In some embodiments, the terminal determines that the fourth information is received and determines that the first policy is effective.

[0245] In some embodiments, the fourth information is used to indicate the time when the first policy takes effect, which may be a periodic time or a time period, which is not limited here.

[0254] In some embodiments, the terminal preferentially transmits the first type of data within the logical channel based on a first strategy.

[0255] In some embodiments, the terminal preferentially selects the first type of logical channel from logical channels based on a first policy to perform data transmission.

[0256] In some embodiments, the terminal updates the priority of the first type of logical channel to the highest priority based on a first policy.

[0257] In some embodiments, the priority of the first type of logical channel is updated to the highest priority. It should be noted that there can be multiple logical channels with the highest priority, and they are not limited to one or more of the first type of logical channels. In addition to the first type of logical channels, they can also be several of the second type of logical channels. Here, the second type of logical channel can be a logical channel in which no first type of data is detected, which is not limited here. In some embodiments, the logical channels include a third logical channel and a fourth logical channel; based on the first policy, the terminal prioritizes data transmission on the third logical channel over data transmission on the fourth logical channel.

[0258] In some embodiments, the third logical channel is the first type logical channel, and the fourth logical channel is a logical channel in which the first type data is not detected.

[0259] In some embodiments, the first type of logical channel includes at least two logical channels, and the terminal determines the priorities of the at least two logical channels based on the remaining time of the first type of data to be transmitted in the logical channels based on the first policy.

[0366] In some embodiments, a certain logical channel may detect the specific type of data to be transmitted.

[0367] In some embodiments, when the logical channel is selected for resource allocation, the MAC will give priority to transmitting the transmission data of the specific type, or allocate resources to the data of the specific type first.

[0368] In some embodiments, when the logical channel is selected for resource allocation, MAC will give priority to transmitting the transmission data of a specific type, or when allocating resources to the data of a specific type first, it may not be subject to the priority bit rate (PBR, Prioritized Bit Rate) limit of the logical channel; at this time, all transmission data of a specific type can be transmitted.

[0369] In some embodiments, the network sends or the protocol agrees on a priority strategy for uplink data packetization, which prioritizes logical channels that detect specific types of data or trigger specific operations.

[0370] In some embodiments, the logical channel that triggers a specific operation may be the logical channel that triggers DSR reporting; or the logical channel group to which the logical channel that triggers the specific operation belongs or all logical channels in the logical channel group that triggers the specific operation.

[0371] In some embodiments, the priority level of a logical channel with a specific type of transmission data is updated to the highest priority level when issued by the network or agreed upon by the protocol. It should be noted that the priority level of a logical channel with a specific type of transmission data (corresponding to the first type of logical channel) is updated to the highest priority level, and at this time, it is at the same high priority level as the logical channel without the specific type of transmission detected.

[0372] In some embodiments, a logical channel with a specific type of transmission data, as issued by the network or as agreed by the protocol, has a higher priority than a logical channel without the specific type of transmission data detected. It should be noted that even if a logical channel without the specific type of transmission data is already at the highest priority, the logical channel with the specific type of transmission data detected will still have a higher priority, i.e., it will be transmitted with higher priority.

[0373] In some embodiments, when the network sends or the protocol agrees on a logical channel with a specific type of transmission data, the priority level is sorted according to the remaining time of the specific type of data, that is, the smaller the remaining time, the logical channel will be transmitted first; (that is, when it is detected that multiple logical channels of a specific type of transmission are also at a high priority level, they are further subdivided according to the minimum remaining time).

[0374] In some embodiments, when allocating resources, resources are first allocated from high to low according to the above logical channel ranking, and at the same time, transmission data of a specific type is preferentially transmitted within a logical channel.

[0375] In some embodiments, the priority policy issued by the network or agreed upon by the protocol when packaging uplink data may become invalid in the following scenarios, that is, the priority policy is no longer used.

[0376] In some embodiments, after the transmission of data of a specific type is completed, the priority policy becomes invalid.

[0377] In some embodiments, the network display indicates that the above priority policy has failed.

[0378] In some embodiments, the network sends or the protocol stipulates in which scenarios the priority policy (corresponding to the first policy) when uplink data is packaged can take effect, that is, in which scenarios the priority policy is used.

[0379] In some embodiments, the base station explicitly instructs the terminal to start using the priority policy when packaging uplink data; at this time, the terminal takes effect according to the agreed time after receiving the priority policy, for example, it takes effect several milliseconds after receiving the priority policy.

[0380] In some embodiments, the base station instructs the terminal to start using the priority policy for uplink data packetization within a time range, for example, within a time range. For example, the priority policy can also be used periodically, that is, a periodic pattern is configured for the terminal, and the terminal uses the priority policy within the time range corresponding to the pattern.
