[0154] 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 (Bluetooth (registered trademark)), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine to Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), system using other communication methods, next-generation system expanded based thereon, and the like. Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).

[0155] In some embodiments, in an extended reality (XR) service, data is usually composed of multiple flows (Qos flow), and the traffic volume is very large. The traffic flow of XR needs to meet certain delay requirements during transmission, especially some data flows need to arrive at the server for decoding at the same time. The delay of any one data flow will cause the joint decoding of multiple data flows to fail. However, the scheduling of the network is dynamic, so in some cases, even if some data flow belongs to a low priority logical channel, if some data packet has not been scheduled for a long time, a buffer status report (BSR) needs to be sent as soon as possible to notify the network. However, according to the related mechanism, only when the data of a high priority logical channel arrives can the BSR be sent, at which time the urgent scheduling requirement cannot be met. Therefore, it is necessary to consider optimizing the case of urgent scheduling in XR.

[0156] In some embodiments, a terminal can report a delay status report (DSR), wherein the DSR carries delay information, for example, information that the remaining time of the uplink data is less than a certain threshold because the uplink data has not been scheduled for a long time.

[0157] In some embodiments, the remaining time of the data packet is the time to discard the data packet, that is, the remaining time is determined according to the discard timer of the packet data convergence protocol (PDCP). The DSR is set to the minimum value of the data or the untransmitted data in the logical channel group (LCG). And the DSR carries the data that needs to be urgently scheduled.

[0158] In some embodiments, the DSR procedure is used to provide the delay status of the LCG to a serving base station (gNB). The delay status of the LCG includes the minimum remaining value of the running PDCP discard timer (discardTimer) for PDCP service data units (SDUs) buffered for the LCG but not yet transmitted in any media access control (MAC) packet data unit (PDU), and the total amount of delay-critical uplink (UL) data for the LCG.

[0159] In some embodiments, for delay-aware link control protocol (LCP) enhancements, RAN2 considers the following options to ignore or adjust the priority of logical channels (LCHs) based on delay or deadline information as a reference: use additional priority configured to LCHs in case these LCHs have delay-critical data.

[0160] FIG. 2a is an interaction diagram illustrating a communication method according to an embodiment of the present disclosure. As shown in FIG. 2a, the embodiment of the present disclosure relates to a communication method for a communication system 100, and the method comprises:

[0161] Step S2101: The network device sends second information to the terminal.

[0162] In some embodiments, the terminal receives the second information sent by the network device.

[0163] In some embodiments, the second information is used to indicate that the priority corresponding to the first logical channel is updated.

[0164] In some embodiments, the second information is used to indicate that the priority corresponding to the first logical channel is updated to a first priority.

[0165] In some embodiments, the network device can send the second information to the terminal after receiving the assistance information sent by the terminal; wherein the assistance information is used to indicate the capability of the terminal supporting updating the priority corresponding to the first logical channel.

[0166] In some embodiments, the first logical channel is used to transmit first type data.

[0167] In some embodiments, the first type data is data that needs to be urgently scheduled.

[0168] In some embodiments, the first type data is data with specific scheduling requirements, for example, delay-critical data.

[0169] In some embodiments, the first type data is data to be transmitted in a logical channel group or a logical channel of a logical channel group.

[0170] In some embodiments, the priority is the priority of transmitting data of the first logical channel.

[0171] In some embodiments, the first priority is a first priority determined from at least two priorities.

[0172] In some embodiments, the second information is used to indicate updating the priority corresponding to the first logical channel and used to indicate updating the priority corresponding to the first logical channel to the first priority.

[0173] In some embodiments, the terminal receives radio resource control (RRC) signaling sent by the network device, and the RRC signaling contains the second information.

[0174] In some embodiments, the terminal receives a media access control (MAC) control element (CE) sent by the network device, and the MAC CE contains the second information.

[0175] In some embodiments, the terminal receives a download control information (DCI) sent by the network device, and the DCI contains the second information.

[0176] In some embodiments, the second information is configured for each logical channel.

[0177] In some embodiments, the second information is configured for each logical channel group.

[0178] In some embodiments, the second information is configured for all logical channel groups of each terminal.

[0179] In some embodiments, the second information is configured for logical channels in all logical channel groups of each terminal.

[0180] For example, the first priority level can be pre-configured or indicated by the network through RRC signaling.

[0181] For example, the network uses RRC signaling to notify the terminal of the specified first priority (which can also be referred to as the first priority level).

[0182] For example, the configuration or indication granularity of the network can be per LCH: for example, indicating that the priority of the logical channel is updated to the first priority under certain conditions.

[0183] For example, the configuration or indication granularity of the network can be per LCG: for example, indicating that the logical channels in the logical channel group update the priority of the logical channel to the first priority under certain conditions.

[0184] For example, the configuration or indication granularity of the network can be per UE: for example, indicating that the logical channels in all uplink channel logical groups of the UE update the priority of the logical channel to the first priority under certain conditions.

[0185] In some embodiments, the second information comprises information of an identification of a logical channel group and / or an identification of a logical channel.

[0186] Exemplarily, the specified logical channel or logical channel group identification is carried in the MAC CE.

[0187] Exemplarily, the specified logical channel or logical channel group identification is carried in the DCI.

[0188] It should be noted that if the priority is updated based on the protocol rule information, step S2102 can be an optional step.

[0189] Step S2102: The terminal updates the priority.

[0190] In some embodiments, the terminal updates the priority corresponding to the first logical channel.

[0191] In some embodiments, the updating can be increasing or decreasing the priority level.

[0192] In some embodiments, the terminal determines that the first condition is met, and updates the priority corresponding to the first logical channel.

[0193] In some embodiments, the first condition comprises at least one of the following:

[0194] The terminal detects the first type of data;

[0195] A delay status report (DSR) needs to be triggered;

[0196] The first type of data needs to be transmitted.

[0197] In some embodiments, the terminal determines that the logical channel group to which the first logical channel belongs is configured with DSR reporting, and determines that the first condition is met, and updates the priority corresponding to the first logical channel.

[0198] It can be understood that the precondition for updating the priority corresponding to the first logical channel can be that the logical channel group to which the first logical channel belongs is configured with DSR reporting.

[0199] In some embodiments, the terminal updates the priority corresponding to the first logical channel to be a first priority of at least two priorities.

[0200] In some embodiments, the terminal can update the priority corresponding to the first logical channel to be any first priority of at least two priorities.

[0201] In some embodiments, the terminal determines the first priority among the at least two priorities based on the first information.

[0202] In some embodiments, the first information is used to indicate at least one of:

[0203] whether the first type of data contains data with a level of importance higher than a first level, the level of importance can be a Public Service Identify (PSI) level;

[0204] an urgency level corresponding to the first type of data.

[0205] In some embodiments, the terminal determines the first priority among the at least two priorities based on whether the first type of data contains data with a level of importance higher than a first level.

[0206] In some embodiments, the terminal determines the first priority among the at least two priorities based on an urgency level corresponding to the first type of data.

[0207] Exemplarily, the at least two priorities include a specified priority 1 and a specified priority 2.

[0208] In some embodiments, when emergency scheduling data is detected in the first logical channel and there is data with a high level of importance (e.g., a high PSI level) in the emergency scheduling data, the terminal updates the priority corresponding to the first logical channel using the specified priority level 1.

[0209] In some embodiments, when emergency scheduling data is detected in the first logical channel and there is no data with a low level of importance in the emergency scheduling data, the terminal updates the priority corresponding to the first logical channel using the specified priority level 2.

[0210] In some embodiments, when specific type of data is detected in the first logical channel, different specified priority levels are used according to the urgency level in the specific type of data. For example, if the remaining duration is lower than a threshold 1, the terminal updates the priority corresponding to the first logical channel using the specified priority level 1; if the remaining duration is lower than a threshold 2, the terminal updates the priority corresponding to the first logical channel using the specified priority level 2; wherein if the threshold 1 is lower than the threshold 2, the priority level of the specified priority level 1 is higher than that of the specified priority level 2.

[0211] In some embodiments, the priority corresponding to the first logical channel is updated based on the first protocol rule information.

[0212] In some embodiments, the terminal determines that the second information is not received, and updates the priority corresponding to the first logical channel based on the first protocol rule information; wherein the second information is used to indicate updating the priority corresponding to the first logical channel and / or updating to the first priority.

[0213] In some embodiments, the first protocol rule information is used to indicate updating the priority corresponding to the first logical channel and / or updating to the first priority. For example, updating to the highest priority. But the priority needs to be lower than that of the signaling radio bearer (SRB).

[0214] In some embodiments, if the network does not issue the second information, the priority corresponding to the first logical channel can not be updated.

[0215] In some embodiments, if the network does not issue the second information, the terminal can still update the priority corresponding to the first logical channel based on the first protocol rule information.

[0216] In some embodiments, the term "information" can be mutually replaced with the terms "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "field", "data", and the like.

[0217] In some embodiments, the term "send" can be mutually replaced with the terms "transmit", "report", "transport", and the like.

[0277] Example 1:

[0278] In some embodiments, the method for protecting the network to update the priority level of the logical channel (corresponding to the first logical channel in the present disclosure) of the terminal to a specified priority level (corresponding to the first priority level in the present disclosure) when the terminal transmits data of a specific type (corresponding to the first type of data in the present disclosure) under specific conditions (corresponding to the first condition in the present disclosure).

[0279] In some embodiments, the network can configure the terminal based on the assistance information reported by the terminal, e.g., the support capability of the terminal (may correspond to the scheme in which the network device sends the second information in the disclosure).

[0280] In some embodiments, the support capability of the terminal can be the capability of the terminal to update the priority level of a logical channel (corresponding to the first logical channel in the disclosure) to a specified priority level (may correspond to the first priority in the disclosure) under certain conditions.

[0281] In some embodiments, the precondition for the terminal to support the capability of updating the priority level of a logical channel (corresponding to the first logical channel in the disclosure) to a specified priority level under certain conditions is that the terminal supports the capability of DSR reporting.

[0282] In some embodiments, the specific type of data is delay-critical data with specific scheduling requirements.

[0283] In some embodiments, it can be that a certain logical channel or logical channel group has data of the specific type to be transmitted.

[0284] In some embodiments, the specific condition can be that the terminal detects the presence of specific type data, or triggers DSR reporting, or needs to transmit specific type data.

[0285] In some embodiments, the precondition for the network to configure the logical channel to update to a specified priority level is that the logical channel group to which the logical channel belongs is configured with a reporting trigger of DSR or DSR reporting.

[0286] In some embodiments, the updating of the priority level of the logical channel to the specified priority level can be more than one specified priority level, which can be used under different trigger conditions (corresponding to the first information in the disclosure):

[0287] In some embodiments, the terminal uses a specified priority level 1 when detecting emergency scheduling data and there is data with high importance level (such as PSI level) in the emergency scheduling data.

[0288] In some embodiments, the terminal uses a specified priority level 2 when detecting emergency scheduling data and there is no data with low importance level in the emergency scheduling data.

[0289] In some embodiments, when detecting specific type data, different specified priority levels are used according to the urgency of the specific type data.

[0290] For example, if the remaining duration is lower than threshold 1, then priority level 1 is used; if the remaining duration is lower than threshold 2, then priority level 2 is used; if threshold 1 is lower than threshold 2, then priority level 1 has higher priority than priority level 2.

[0291] In some embodiments, the specified priority level can be pre-configured or indicated by the network through RRC signaling:

[0292] In some embodiments, the network uses RRC signaling to inform the terminal of the specified target logical channel priority level (corresponding to the first priority).

[0298] In some embodiments, it is indicated that the logical channel in all uplink channel logical channel groups of the UE will update the logical channel priority level to the specified priority level under certain conditions.

[0299] In some embodiments, the specified priority level can be configured or indicated by the network through MAC CE signaling or DCI:

[0300] In some embodiments, the MAC CE will carry the specified logical channel or logical channel group identifier.

[0301] In some embodiments, the DCI will carry the specified logical channel or logical channel group identifier.

[0302] In some embodiments, the network uses MAC CE to inform the terminal of the specified UE's logical channel, which will update the logical channel priority level to the specified priority level under certain conditions.

[0303] In some embodiments, the network uses MAC CE to inform the terminal of the specified UE's logical channel group, which will update the logical channel in the logical channel group, and the priority level to the specified priority level under certain conditions.

[0304] In some embodiments, the network uses DCI to inform the terminal of the logical channel of the specified UE, and updates the priority level of the logical channel to the specified priority level under certain conditions.

[0305] In some embodiments, the network uses DCI to inform the terminal of the logical channel group of the specified UE, and updates the priority level of the logical channel in the logical channel group to the specified priority level under certain conditions.

[0306] In some embodiments, if the network does not issue the logical channel priority level update to the specified priority level when having transmission data of a certain type under certain conditions, the specified priority level can be as follows:

[0307] Exemplarily, the logical channel priority level when having transmission data of a certain type under certain conditions is updated (i.e. not configured, then not updated).

[0308] Exemplarily, the logical channel priority level when having transmission data of a certain type under certain conditions is updated to the protocol agreed (corresponding to the first communication rule) level, such as the highest level, or the highest level but lower than the SRB level.
