[0114] XR refers to a real and virtual combination of a human-computer interactive environment generated by computer technology and wearable devices. XR is a collective term for augmented reality (AR), virtual reality (VR), mixed reality (MR), and other technologies. By integrating the visual interaction technologies of AR, VR, and MR, users can experience the "immersion" of seamless conversion between the virtual world and the real world. In XR services, a service flow is usually composed of multiple data flows (such as quality of service flow (QoS flow), and has a very large amount of data.

[0115] In practical applications, the transmission of the service flow of the XR service needs to meet certain delay requirements, especially some data flows need to arrive at the network function at the same time for synchronous processing (for example, joint decoding). The delay of any one data flow will cause the synchronous processing of multiple data flows to fail. Therefore, in 5G technology, the priority of the logic channel (LC) is used to schedule the data flow. However, the scheduling of the network device is dynamic, so in some cases, even if some data flows belong to a low-priority logic channel, if some data packets have not been scheduled for a long time, the terminal needs to send a buffer status report (BSR) to notify the network as soon as possible.

[0116] In some embodiments, a DSR reporting process is introduced, that is, the terminal can trigger the DSR reporting process, which carries the delay related information of data transmission, for example, the information that the uplink data has not been scheduled for a long time, causing the remaining time of the data packet to be less than a certain threshold. The remaining time of the data packet is the time length from the data packet being discarded. Exemplarily, the remaining time can be determined according to the discard timer of the packet data convergence protocol (PDCP).

[0117] In some embodiments, the DSR procedure is used to provide a delay status of a logic channel group (LCG) to a serving base station. The delay status of the LCG includes a remaining time, which refers to a minimum remaining value of a discard timer for PDCP in a service data unit (SDU) buffered for the LCG, and delay-critical UL data of the LCG associated with a data volume computation procedure for an associated radio link control (RLC) entity and PDCP entity.

[0118] In some embodiments, under certain conditions (e.g., the terminal detects the presence of delay-critical data in a logic channel), the terminal needs to temporarily promote the priority level of the logic channel, and the priority level of the logic channel is configured by the network. However, the network does not explicitly inform the terminal when to promote the priority level of the logic channel, and the specific trigger condition for the promotion of the priority level of the logic channel has not been specified. Therefore, how the terminal implements the promotion of the priority level of the logic channel is a problem to be solved.

[0119] In some embodiments, the terms "delay-critical data", "emergency scheduling data", and "delay-critical UL data" can be replaced with each other.

[0120] In some embodiments, the terms "logic channel" and "logic channel group" can be replaced with each other.

[0121] To this end, the embodiments of the present disclosure provide a communication method, apparatus, device, communication system, storage medium, and program product. The terminal updates a logic channel associated with data having a preset scheduling requirement to a first priority level when a first condition is met, so as to update the priority level of the logic channel by the terminal, so that the data having the preset scheduling requirement can be preferentially scheduled, the timely transmission of the data having the preset scheduling requirement is completed, and the enhancement of data packet processing is achieved.

[0122] In some embodiments, the "data packet" involved in the embodiments of the present disclosure can be a fraction data unit (PDU) of a PDCP entity, an SDU, or the like.

[0123] In some embodiments, the first data packet can comprise data with preset scheduling requirements, such as data with urgent scheduling requirements. In some embodiments, the data with urgent scheduling requirements can comprise delay-critical data. In an example, the delay-critical data can be data with higher requirements on delay. In an example, the delay-critical data can be data sensitive to delay. It can be understood that the delay-critical data has higher requirements on delay and / or is sensitive to delay, and thus has urgent scheduling requirements.

[0124] In some embodiments, the first data packet can comprise data with a remaining time less than or equal to a preset threshold, data for which scheduling has lagged and a multi-flow synchronization threshold between data flows cannot be met, and the like.

[0125] In some embodiments, the remaining time can refer to a time length from when the data packet is discarded. In an example, the remaining time can be indicated by the timer described above.

[0126] FIG. 2 is an interaction schematic diagram of a communication method according to an embodiment of the present disclosure. The communication method related by the embodiment of the present disclosure can be applied to the communication system 100. As shown in FIG. 2, the communication method of the embodiment of the present disclosure comprises steps S201 to S205.

[0127] In step S201, the terminal determines that a first condition is met.

[0128] In some embodiments, the first condition is used to trigger the terminal to update the priority of a logical channel. In some embodiments, the first condition is used to trigger the terminal to improve the priority of a logical channel.

[0129] In some embodiments, the first condition can be that the terminal detects a first data packet on a certain logical channel or certain logical channels, at which time the logical channel on which the first data packet is detected is the second logical channel. Then, the first condition can also be that the terminal detects a first data packet on the second logical channel. In some embodiments, the first condition can also be that the terminal detects data with preset scheduling requirements on the second logical channel. In some embodiments, the first condition can also be that the terminal detects data to be sent on the second logical channel as data with preset scheduling requirements.

[0130] In some embodiments, the terminal detects a first data packet on one or more logical channels (i.e., the second logical channel), at which time the terminal determines that the first condition is met. In some embodiments, the terminal detects data with preset scheduling requirements on one or more logical channels (i.e., the second logical channel), at which time the terminal determines that the first condition is met. In an example, the terminal detects a data packet with a remaining time less than a preset threshold on one or more second logical channels, at which time the terminal determines that the first condition is met.

[0131] In some embodiments, in the case that the first data packet is detected on one or more second logical channels, the one or more second logical channels have the first data packet. In some embodiments, in the case that the first data packet is detected on one or more second logical channels, there is data with preset scheduling requirement on the one or more second logical channels. In some embodiments, in the case that the first data packet is detected on one or more second logical channels, the data to be sent on the one or more second logical channels is the first data packet. In some embodiments, in the case that data with preset scheduling requirement is detected on one or more second logical channels, the data to be sent on the one or more second logical channels is the data with preset scheduling requirement.

[0132] In an example, the data with preset scheduling requirement is data with urgent scheduling requirement.

[0133] In some embodiments, the second logical channel can be one or more of the logical channels used by the terminal for uplink transmission. In some embodiments, the plurality of second logical channels can belong to the same logical channel group or different logical channel groups.

[0134] In step S202, the terminal determines the first logical channel.

[0135] In some embodiments, the terminal can determine the first logical channel from one or more second logical channels. In some embodiments, the terminal can determine the first logical channel from one or more second logical channels having the first data packet.

[0136] In some embodiments, the first logical channel can be determined based on DSR reporting. In some embodiments, the first logical channel can be a logical channel associated with DSR reporting. In some embodiments, the first logical channel is a logical channel that meets the trigger condition of DSR reporting. In some embodiments, the first logical channel is a logical channel that triggers DSR reporting. In some embodiments, the logical channel group to which the first logical channel belongs is configured for DSR reporting.

[0137] In some embodiments, among the second logical channels having the first data packet, only the logical channel that triggers DSR reporting is determined as the first logical channel. In some embodiments, the network device can configure a logical channel or a logical channel group for DSR reporting, and configure a remaining time threshold for the logical channel or the logical channel group. Then, the second logical channel whose remaining time of the first data packet is less than the remaining time threshold can be determined as the first logical channel.

[0138] In an example, the terminal detects one or more logical channels (i.e., second logical channels) having the first data packet, and determines, as the first logical channel, a logical channel among the detected logical channels that is associated with the DSR reporting. In an example, the terminal detects one or more logical channels having the first data packet, and determines, as the first logical channel, a logical channel among the detected logical channels that triggers the DSR reporting. In an example, the terminal detects one or more logical channels having the first data packet, and determines, as the first logical channel, a logical channel among the detected logical channels that belongs to a logical channel group configured for the DSR reporting.

[0139] In some embodiments, the first logical channel can be determined based on a remaining time of the first data packet. In some embodiments, the first logical channel is a logical channel having a remaining time of the first data packet satisfying a second condition. In some embodiments, the second condition can include that the remaining time of the data packet is less than a preset threshold, and the first logical channel is a logical channel having a remaining time of the first data packet less than the preset threshold. In some embodiments, the second condition can include that the remaining time of the data packet is within a preset time duration, and the first logical channel is a logical channel having a remaining time of the first data packet within the preset time duration.

[0140] In some embodiments, the preset threshold is less than a remaining time threshold (remainingTimeThreshold) for triggering the DSR reporting associated with the first logical channel. Here, the remaining time threshold is either specified by a protocol or configured by a network device. In some embodiments, the network device can configure a logical channel or a logical channel group for the DSR reporting, and configure a remaining time threshold for the logical channel or the logical channel group. The remaining time threshold is greater than the preset threshold. Then, a second logical channel having a remaining time of the first data packet less than the preset threshold can be determined as the first logical channel.

[0141] In an example, the terminal detects one or more logical channels (i.e., second logical channels) having the first data packet, and determines, as the first logical channel, a logical channel among the detected logical channels that has a remaining time of the first data packet less than a preset threshold.

[0142] In some embodiments, in a case where the first logical channel is determined based on a remaining time of the first data packet, a logical channel group to which the first logical channel belongs can be configured for the DSR reporting, or a logical channel group to which the first logical channel belongs can not be configured for the DSR reporting.

[0143] In some embodiments, the first data packet on the first logical channel is not transmitted. In some embodiments, the first data packet on the first logical channel is not reported by the DSR.

[0144] In step S203, the terminal updates the priority of the first logical channel to the first priority.

[0145] In some embodiments, the first priority can be a specified priority. In some embodiments, the specified priority can be determined by the terminal based on its own implementation, configured by the network device, or specified by a protocol. In some embodiments, a logical channel or a logical channel group can be associated with a priority (i.e., a specified priority) for logical channel priority updating. In step S203, the terminal can update the first logical channel to the associated specified priority (i.e., the first priority).

[0146] In some embodiments, the first priority can be higher than the original priority (e.g., the second priority) of the first logical channel. In the case where the priority of the first logical channel is updated to the first priority, the priority of the first logical channel is promoted, so that the first data packet on the first logical channel can be preferentially scheduled, thereby enabling timely transmission of the first data packet and enhancing data packet processing.

[0147] In some embodiments, the terminal triggers logical channel priority updating for the first logical channel, so that the priority of the first logical channel is updated to the first priority.

[0148] In some embodiments, the specified priority associated with a logical channel or a logical channel group can have a validity time. In some embodiments, the validity time of the specified priority can be a validity time point or a validity time period.

[0149] In some embodiments, the first priority is valid at a first time. In some embodiments, the validity time of the first priority can be a first time point or a first time period.

[0150] In some embodiments, at the first time point, the terminal updates the priority of the first logical channel to the first priority. In some embodiments, during the first time period, the terminal maintains the priority of the first logical channel as the first priority.

[0151] In some embodiments, the first time point can be the time point at which the terminal detects the first data packet. In some embodiments, when the terminal detects the first data packet on a logical channel in step S201 (i.e., the first time point), the specified priority associated with the logical channel is valid, and at this time, the terminal updates the priority of the first logical channel to the first priority. In an example, when the terminal detects that the logical channel A has the first data packet, the specified priority associated with the logical channel A is valid, and the terminal updates the priority of the logical channel A to the first priority.

[0152] In some embodiments, the first time point can be a time point at which the first logical channel triggers the DSR reporting. In some embodiments, after the terminal detects the first data packet on the logical channel in step S201, the specified priority associated with the logical channel takes effect at the time point at which the logical channel triggers the DSR reporting (i.e., the first time point), and the terminal updates the priority of the first logical channel to the first priority. In an example, the terminal detects the first data packet on the logical channel A, and the logical channel A is associated with the DSR reporting. When the logical channel A triggers the DSR reporting, the specified priority associated with the logical channel A takes effect, and the terminal updates the priority of the logical channel A to the first priority.

[0153] In some embodiments, the first time period can be a time period during which the terminal performs logical channel prioritization (LCP). In some embodiments, the specified priority associated with the logical channel takes effect during the time period (i.e., the first time period) during which the terminal performs the LCP, and the terminal keeps the priority of the first logical channel as the first priority. In an example, the terminal detects the first data packet on the logical channel A, and the logical channel A is associated with the DSR or the remaining time of the first data packet on the logical channel A is less than a preset threshold. At this time, the terminal updates the priority of the first logical channel to the first priority, and the specified priority associated with the logical channel A takes effect during the time period during which the terminal performs the LCP, and the terminal keeps the priority of the logical channel A as the first priority.

[0154] In some embodiments, during the first time period, the priority of the logical channel other than the first logical channel in the second logical channel remains unchanged.

[0155] In step S204, the terminal transmits the first data packet on the first logical channel.

[0156] In some embodiments, the network device receives the first data packet. In some embodiments, the first data packet can also be transmitted to other subjects, such as other terminals, and the embodiments of the present disclosure do not make specific limitations thereto.

[0157] In step S205, the terminal restores the priority of the first logical channel to the second priority.

[0158] In some embodiments, after the terminal ends the transmission of the first data packet, the terminal can restore the priority of the first logical channel, i.e., restore the priority of the first logical channel to the second priority.

[0159] In some embodiments, after the first time ends, the first priority is invalidated, and the priority of the first logical channel is restored to the original priority (i.e., the second priority).

[0160] In some embodiments, the priority of the first logical channel is restored to the second priority after the first data packet is completed with scheduling. In some embodiments, the priority of the first logical channel is restored to the second priority after the terminal ends the procedure of LCP.

[0161] Up to now, the terminal completes the processing of the data packet.

[0162] In an example, the terminal detects that there is data with urgent scheduling requirement on logical channel A, logical channel B and logical channel C, wherein the logical channel A triggers DSR reporting. Then, when the logical channel A triggers DSR reporting, the terminal updates the priority of the logical channel A to priority 1, and the priorities of the logical channel B and the logical channel C remain to be priority 2 (priority 1 is higher than priority 2). Then, the terminal transmits the data with urgent scheduling requirement of the logical channel A according to the priority 1, and after the transmission ends, the terminal restores the priority of the logical channel A to the priority 2.

[0163] In an example, the terminal detects that there is data with urgent scheduling requirement on logical channel A, logical channel B and logical channel C, wherein the remaining time of the data with urgent scheduling requirement on the logical channel A is less than a preset threshold. At this time, the terminal updates the priority of the logical channel A to priority 1, and the priorities of the logical channel B and the logical channel C remain to be priority 2 (priority 1 is higher than priority 2). Then, the terminal transmits the data with urgent scheduling requirement of the logical channel A according to the priority 1, and after the transmission ends, the terminal restores the priority of the logical channel A to the priority 2.

[0164] In an example, the terminal detects that there is data with urgent scheduling requirement on logical channel A, logical channel B and logical channel C, wherein the remaining time of the data with urgent scheduling requirement on the logical channel A is less than a preset threshold. Then, during the execution of the procedure of LCP, the terminal maintains the priority of the logical channel A to be priority 1, and the priorities of the logical channel B and the logical channel C remain to be priority 2 (priority 1 is higher than priority 2). Then, the terminal transmits the data with urgent scheduling requirement of the logical channel A according to the priority 1, and after ending the procedure of LCP, the terminal can restore the priority of the logical channel A to the priority 2.

[0165] In an example, the terminal detects that there is data with urgent scheduling requirement on logical channel A, logical channel B and logical channel C, wherein the logical channel A triggers DSR reporting. Then, in the process of performing LCP, the terminal keeps the priority of the logical channel A as priority 1, and keeps the priorities of the logical channel B and the logical channel C as priority 2 (priority 1 is higher than priority 2). Then, the terminal transmits the data with urgent scheduling requirement of the logical channel A according to the priority 1, and after ending the process of LCP, the terminal can restore the priority of the logical channel A to the priority 2.

[0167] In some embodiments, step S204 is optional, and one or more of these steps can be omitted or replaced in different embodiments.

[0168] In the embodiments of the present disclosure, by updating the logical channel associated with the data with the preset scheduling requirement to the first priority when the first condition is met, the priority of the logical channel is updated, so that the data with the preset scheduling requirement can be scheduled preferentially, thereby realizing the timely transmission of the data with the preset scheduling requirement, and enhancing the data packet processing.

[0198] In the following, the technical solutions of the embodiments of the present disclosure are exemplarily described through specific embodiments.

[0199] In some embodiments, a method for updating the priority of a logical channel to a specified priority when a terminal transmits data of a specific type (i.e., the first data packet) under a specific trigger condition (i.e., the first condition) is provided.

[0200] In some embodiments, the data of the specific type is delay-critical data.

[0201] In some embodiments, a certain logical channel or logical channel group has data of the specific type to be transmitted.

[0202] In some embodiments, the logical channel that needs to be prioritized can be selected according to the following rules.

[0203] Method 1: selection according to DSR triggering.

[0204] In some embodiments, only the LCH that triggers DSR can update the priority of the logical channel to the specified priority under the specific trigger condition, i.e., other LCHs that do not trigger DSR maintain the original priority of the logical channel.

[0205] In some embodiments, among the LCHs that trigger DSR, there is data of the specific type to be transmitted, the minimum remaining duration of the data is lower than the DSR configuration threshold 1, and the data has not been transmitted or reported on DSR. In this case, the priority of the logical channel is updated to the specified priority.

[0206] In some embodiments, when DSR is reported, only the LCH associated with the LCG reported in the report can update the priority of the logical channel to the specified priority under the specific trigger condition.

[0207] In some embodiments, for a certain LCH, the logical channel priority level is updated to a specified priority level under certain trigger conditions only when it is detected that there is emergency scheduling data (the minimum remaining time of the data is lower than a DSR configuration threshold threshold). The LCH does not necessarily have to be the LCH that triggers the DSR.

[0208] In some embodiments, the LCG to which the logical channel whose priority level needs to be promoted belongs is configured with DSR trigger reporting.

[0209] Method 2: selection according to the remaining time of the data.

[0210] In some embodiments, the terminal updates the logical channel priority level to a specified priority level when it detects that there is a certain type of data for a certain logical channel, and the remaining time of the data is lower than threshold 2 or within a specified threshold range. In an example, threshold 2 is lower than the reporting trigger threshold 1 (i.e. the remaining time threshold) of the DSR.

[0211] In some embodiments, in addition to the minimum remaining time of the data being lower than threshold 2, other factors can also be considered for the logical channel whose priority level needs to be promoted, such as the data not having been transmitted or not having been reported on the DSR, and the logical channel priority level is updated to a specified priority level.

[0212] In some embodiments, the LCG to which the logical channel whose priority level needs to be promoted belongs does not necessarily have to be configured with DSR trigger reporting.

[0213] In some embodiments, the time or period when the terminal promotes the logical channel can be at least one of the following:

[0214] When the LCH triggers the DSR reporting (i.e. the time of validity), the logical channel priority level is updated to a specified priority level;

[0215] When the LCP procedure is performed (i.e. the period of validity), the logical channel priority level is updated to a specified priority level.
