Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a method for adjusting priorities, a storage medium, a chip system, and a communication system. Background Art

[0002] Extended reality (XR) services are a type of multimedia service that combines the real and virtual worlds through computer technology and wearable devices, enabling human-computer interaction and providing an "immersive" experience of seamless conversion between the virtual world and the real world for users. XR services often have high requirements for the latency of communication networks. To ensure the transmission performance of XR services, the priority of the logical channels carrying XR service data can be configured so that the data of the logical channels with higher priority can be processed preferentially. However, the current logical channel priority configuration scheme has low flexibility and is difficult to meet diverse service requirements. Summary of the Invention

[0003] Embodiments of this application provide a method for adjusting priorities, a storage medium, a chip system, and a communication system, which are beneficial to improving the flexibility of a terminal device in adjusting the priorities of logical channels to adapt to different service requirements.

[0004] In a first aspect, embodiments of this application provide a method for adjusting priorities. This method can be applied to a terminal device, or to a device in the terminal device (such as a chip, or a chip system, or a circuit), or to a device that can be used in conjunction with the terminal device. Hereinafter, an example of applying it to a terminal device will be described. The method may include: receiving first indication information from a network device; the first indication information is used to determine an additional priority of a first logical channel; when the transmission information of the first logical channel meets a trigger condition, adjusting the priority of the first logical channel from a static priority to the additional priority of the first logical channel; the additional priority of the first logical channel is higher than the static priority of the first logical channel; and sending data corresponding to the first logical channel to the network device based on the additional priority of the first logical channel.

[0005] Based on this method for adjusting priorities, the terminal device can determine the additional priority of the first logical channel based on the first indication information sent by the network device, and when the actual transmission situation of the first logical channel meets the trigger condition, raise the priority of the first logical channel from the static priority to the additional priority. In this way, it helps to achieve flexible adjustment of the logical channel priorities, thereby improving the rationality of resource allocation and meeting the latency requirements of different services.

[0006] In a possible implementation, the first indication information is used to indicate the mapping relationship between the reference auxiliary information of N logical channels and the additional priorities of the N logical channels. The N logical channels include a first logical channel; N is a positive integer. The method further includes: determining the additional priority of the first logical channel according to the mapping relationship and the reference auxiliary information of the first logical channel.

[0007] In this technical solution, the first indication information can be used to indirectly indicate the additional priority of the first logical channel. The terminal device can adaptively and dynamically select the additional priority of the first logical channel based on the mapping relationship indicated by the first indication information and in combination with the reference auxiliary information. This helps to achieve fine-grained adjustment of the logical channel priorities.

[0008] In a possible implementation, the reference auxiliary information of the first logical channel includes at least one of the following: the transmission time parameter corresponding to the first logical channel; the service type corresponding to the first logical channel; the traffic characteristic parameter corresponding to the first logical channel.

[0009] In a possible implementation, the transmission information of the first logical channel satisfying the trigger condition includes at least one of the following: the remaining transmission time of the first logical channel is equal to the transmission time parameter corresponding to the first logical channel; the service type corresponding to the first logical channel is a preset service type; the traffic characteristic parameter corresponding to the first logical channel is greater than or equal to a preset traffic characteristic parameter.

[0010] In this technical solution, the transmission information of the first logical channel satisfying the trigger condition may indicate that: the data of the first logical channel needs to be transmitted preferentially, or in other words, the data of the first logical channel needs to be preferentially allocated transmission resources. Thus, the terminal device can raise the static priority of the first logical channel to the additional priority of the first logical channel in order to optimize the data transmission performance and meet the low-latency requirements of the service.

[0011] In a possible implementation, the reference auxiliary information of the first logical channel includes the transmission time parameter corresponding to the first logical channel. In response to the transmission time parameter corresponding to the first logical channel being less than a first time threshold, the additional priority of the first logical channel is a first additional priority. In response to the transmission time parameter corresponding to the first logical channel being greater than or equal to the first time threshold and less than a second time threshold, the additional priority of the first logical channel is a second additional priority. Wherein, the first additional priority is higher than the second additional priority.

[0012] In this technical solution, the smaller the transmission time parameter corresponding to the first logical channel, the more urgent the data transmission time of the first logical channel. Therefore, the corresponding additional priority can be higher. This is beneficial to improving the flexibility of the logical channel priorities in order to better adapt to the dynamically changing service requirements.

[0013] In a possible implementation, the first indication information is used to indicate the additional priority of the first logical channel.

[0014] In this technical solution, the first indication information can be used to directly indicate the additional priority of the first logical channel, which is beneficial to improving the processing efficiency of the terminal device.

[0015] In a second aspect, an embodiment of the present application provides another priority adjustment method. This method can be applied to a network device, or a device in the network device (for example, a chip, or a chip system, or a circuit), or a device that can be used in combination with the network device. Hereinafter, an example of applying it to a network device will be described. The method may include: sending first indication information to a terminal device; the first indication information is used to determine the additional priority of the first logical channel; the additional priority of the first logical channel is used to trigger the adjustment of the priority of the first logical channel from the static priority to the additional priority of the first logical channel when the transmission information of the first logical channel meets the trigger condition; the additional priority of the first logical channel is higher than the static priority of the first logical channel.

[0016] Based on this priority adjustment method, the network device sends the first indication information to the terminal device, so that the terminal device can determine the additional priority of the first logical channel based on the first indication information, and when the actual transmission situation of the first logical channel meets the trigger condition, raise the priority of the first logical channel from the static priority to the additional priority. In this way, it helps to achieve flexible adjustment of the logical channel priority, thereby improving the rationality of resource allocation and meeting the delay requirements of different services.

[0017] In a possible implementation, the first indication information is used to indicate the mapping relationship between the reference auxiliary information of N logical channels and the additional priority of the N logical channels. The N logical channels include the first logical channel; N is a positive integer.

[0018] In this technical solution, the first indication information can be used to indirectly indicate the additional priority of the first logical channel, so that the terminal device can adaptively and dynamically select the additional priority of the first logical channel based on the mapping relationship indicated by the first indication information in combination with the reference auxiliary information. In this way, it helps to achieve fine-grained adjustment of the logical channel priority.

[0019] In a possible implementation, the reference auxiliary information of the first logical channel includes at least one of the following: the transmission time parameter corresponding to the first logical channel; the service type corresponding to the first logical channel; the traffic characteristic parameter corresponding to the first logical channel.

[0020] In a possible implementation, the transmission information of the first logical channel satisfying the triggering condition includes at least one of the following: the remaining transmission time of the first logical channel is equal to the transmission time parameter corresponding to the first logical channel; the service type corresponding to the first logical channel is a preset service type; the traffic characteristic parameter corresponding to the first logical channel is greater than or equal to a preset traffic characteristic parameter.

[0021] In this technical solution, the fact that the transmission information of the first logical channel satisfies the triggering condition may indicate that the data of the first logical channel needs to be transmitted preferentially, or in other words, the data of the first logical channel needs to be preferentially allocated transmission resources.

[0022] In a possible implementation, the reference auxiliary information of the first logical channel includes the transmission time parameter corresponding to the first logical channel; in response to the transmission time parameter corresponding to the first logical channel being less than the first time threshold, the additional priority of the first logical channel is the first additional priority; in response to the transmission time parameter corresponding to the first logical channel being greater than or equal to the first time threshold and less than the second time threshold, the additional priority of the first logical channel is the second additional priority; wherein, the first additional priority is higher than the second additional priority.

[0023] In this technical solution, the smaller the transmission time parameter corresponding to the first logical channel, the more urgent the data transmission time of the first logical channel is, so the corresponding additional priority can be higher. This is beneficial to improving the flexibility of the logical channel priority, so as to better adapt to the dynamically changing service requirements.

[0024] In a possible implementation, the first indication information is used to indicate the additional priority of the first logical channel. That is to say, the first indication information can be used to directly indicate the additional priority of the first logical channel.

[0025] In a possible implementation, the above method further includes: determining the additional priority of the first logical channel according to the reference auxiliary information of the first logical channel.

[0026] In this technical solution, the network device can combine the reference auxiliary information of the first logical channel to determine the additional priority of the first logical channel, which is beneficial for the network device to optimize the configuration of the additional priority according to the actual situation.

[0027] In a possible implementation, determining the additional priority of the first logical channel according to the reference auxiliary information of the first logical channel as described above includes: determining the priority adjustment value of the first logical channel according to the reference auxiliary information of the first logical channel; adjusting the static priority of the first logical channel according to the priority adjustment value of the first logical channel to obtain the additional priority of the first logical channel.

[0028] In this technical solution, the network device may first determine the priority adjustment value of the first logical channel, and then determine the additional priority of the first logical channel according to the priority adjustment value of the first logical channel, which is beneficial to the refined priority adjustment of the first logical channel.

[0029] In a possible implementation, the reference auxiliary information of the first logical channel includes the service type corresponding to the first logical channel; in response to the service type corresponding to the first logical channel being the first type, the priority adjustment value of the first logical channel is the first adjustment value; in response to the service type corresponding to the first logical channel being the second type, the priority adjustment value of the first logical channel is the second adjustment value; where the first type is different from the second type, and the first adjustment value and the second adjustment value may be the same or different.

[0030] In this technical solution, different service types may correspond to the same priority adjustment value, or different service types may correspond to different priority adjustment values, which is beneficial to more flexibly determining the additional priority of the first logical channel.

[0031] In a possible implementation, the above method further includes: receiving the reference auxiliary information of the first logical channel from the terminal device.

[0032] In this technical solution, the network device obtains the reference auxiliary information of the first logical channel provided by the terminal device to better meet the requirements of different services.

[0043] Please refer to Figure 1 , Figure 1 FIG. for an architectural schematic diagram of a communication system to which embodiments of the present application are applied. As Figure 1 shown, the communication system may include a radio access network (RAN) 100 and a core network (CN) 101. Among them, the RAN 100 may include at least one network device (such as 110a and 110b, collectively referred to as 110), and at least one terminal device (such as 120a - 120j, collectively referred to as 120).

The terminal device in this application can be a device with wireless transceiver functions and can communicate with one or more core network devices (or also referred to as core devices) via network devices in the radio access network (or also referred to as access network devices or access devices).

[0047] It should be noted that Figure 1 the number and form of the devices in the examples are for illustration purposes and do not constitute a limitation on the embodiments of this application.

[0048] To facilitate the understanding of the technical solution of this application, some related concepts or technologies involved in this application are introduced below. This part is only for easy understanding and should not be regarded as a specific limitation of this application.

[0049] 1. Extended Reality (XR) services XR services are a type of multimedia service that combines the real and virtual worlds through computer technology and wearable devices, enabling human-computer interaction, and bringing an "immersive feeling" of seamless conversion between the virtual world and the real world to the experiencer. XR services impose higher requirements on the communication network bandwidth and latency. It encompasses various technologies such as virtual reality (VR), augmented reality (AR), and mixed reality (MR). Data with strict requirements for transmission latency in XR services can be called latency-critical data. For example, real-time voice communication data, online game data, remote medical data, etc. all require low latency to ensure transmission performance.

[0050] 2. Logical Channel Prioritization (LCP) In a wireless communication system, logical channel prioritization is a parameter used to determine the priority order of different logical channels during resource allocation and scheduling. Logical channel prioritization can be pre-configured by network devices. For example, network devices can configure static priorities based on parameters such as service type and quality of service requirements. In one implementation, the higher the value of the logical channel prioritization, the lower the priority it represents, and the lower the value of the logical channel prioritization, the higher the priority it represents. By configuring logical channel prioritization, in the case of limited resources, high-priority logical channels can obtain resources first to ensure the performance of critical services. In the embodiments of this application, logical channel prioritization can also be described as the static priority of logical channels.

[0051] Currently, after being configured by network devices, the logical channel prioritization usually remains unchanged unless the network devices reconfigure it. However, this way of configuring priorities lacks flexibility and is difficult to meet the requirements of different service scenarios.

[0052] Based on this, the embodiments of this application provide a priority adjustment method, which is beneficial to enhancing the flexibility of logical channel prioritization to facilitate adapting to the needs of different services.

[0053] The priority adjustment method provided by the embodiments of this application is introduced in detail below.

[0054] Please refer to Figure 2 , Figure 2This is a schematic flowchart of a priority adjustment method provided by an embodiment of the present application. As Figure 2 shown, the priority adjustment method includes: S201, the network device sends the first indication information to the terminal device. Correspondingly, the terminal device receives the first indication information from the network device.

[0055] The first indication information can be used to determine the additional priority of the first logical channel. The additional priority of the first logical channel can be understood as the priority other than the static priority of the first logical channel, and the additional priority of the first logical channel can be higher than the static priority of the first logical channel. By introducing the additional priority of the logical channel, more fine-grained priority control can be achieved, so as to better meet the requirements of different service scenarios.

[0056] In the embodiment of the present application, the additional priority can also be referred to as or replaced by other names such as additional priority, enhanced priority, appended priority, etc., and no limitation is made thereto.

[0057] In a possible implementation, the first indication information can be carried in a media access control element (MAC CE). By carrying the first indication information in the MAC CE, it is beneficial to transmit the first indication information more efficiently.

[0058] Optionally, the first indication information can be used to indirectly indicate the additional priority of the first logical channel, or can also be used to directly indicate the additional priority of the first logical channel.

[0059] In some embodiments, for the case where the first indication information is used to indirectly indicate the additional priority of the first logical channel, the first indication information can specifically be used to indicate the mapping relationship between the reference auxiliary information of N logical channels and the additional priority of the N logical channels. The N logical channels can include the first logical channel, and N is a positive integer. Among them, the reference auxiliary information can be understood as the information used to assist in making a decision on the additional priority, and the reference auxiliary information can also be described as auxiliary decision-making information or other names.

[0060] Optionally, the reference auxiliary information of the first logical channel can include at least one of the following: the transmission time parameter corresponding to the first logical channel; the service type corresponding to the first logical channel; the traffic characteristic parameter corresponding to the first logical channel.

[0061] Among them, the transmission time parameter corresponding to the first logical channel can be understood as the maximum delay time allowed for the data of the first logical channel. That is to say, to meet the low-latency requirements of XR services, the data of the first logical channel needs to be transmitted within the time specified by the transmission time parameter. In some scenarios, if the transmission time parameter corresponding to the first logical channel is small, it can indicate that the data transmission time of the first logical channel is relatively urgent, or rather, the data latency requirement of the first logical channel is relatively high. In this case, the additional priority corresponding to the first logical channel can be a higher priority to meet the latency requirement of the data. Optionally, in the embodiments of the present application, the transmission time parameter can also be referred to as or replaced with other names such as remaining time threshold, delay budget, transmission time threshold, etc. Different transmission time parameters can be configured for different data.

[0062] The service type corresponding to the first logical channel can be understood as the service type to which the data of the first logical channel belongs. The first logical channel can transmit data of different service types. By dividing the service types, it is beneficial to meet the diverse needs of different services. In some scenarios, if the service type corresponding to the first logical channel is a preset service type, for example, some key services or emergency services can be configured as the preset service type according to actual needs. In this case, the additional priority corresponding to the first logical channel can be a higher priority to ensure that the data of these preset service types can be transmitted efficiently and reliably.

[0063] The traffic characteristic parameter corresponding to the first logical channel can include the size of the data volume of the first logical channel and / or the change size of the data volume of the first logical channel. By considering the traffic characteristic parameter corresponding to the first logical channel, it is beneficial to more flexibly allocate resources according to the data volume of the logical channel to ensure service performance. In some scenarios, if the data volume of the first logical channel is large, it can indicate that the data of the first logical channel requires more transmission time. In this case, the additional priority corresponding to the first logical channel can be a higher priority to facilitate the timely transmission of a large amount of data of the first logical channel.

[0064] The following uses two specific examples to illustrate how the first indication information indicates the mapping relationship between the reference auxiliary information of the first logical channel and the additional priority of the first logical channel. It should be noted that in the embodiments of the present application, it is exemplified that the smaller the priority value, the higher the priority. In some embodiments, it can also be that the larger the priority value, the higher the priority, which is not limited thereto.

[0065] Example 1: Assuming that the reference auxiliary information of the first logical channel includes the transmission time parameter corresponding to the first logical channel, the first indication information may be, for example, a mapping relationship between the reference auxiliary information of the first logical channel (including the transmission time parameter corresponding to the first logical channel) and the additional priority of the first logical channel in the form of Table 1: Table 1

[0066] in, may represent the static priority of the data corresponding to the first logical channel, T may represent the transmission time parameter corresponding to the first logical channel, 0< < , 0≤ < < < .

[0067] The transmission time parameter T corresponding to the first logical channel is less than the first time threshold In the case of , it means that the transmission time parameter T corresponding to the first logical channel is relatively small, and the additional priority of the first logical channel can be That is to say, when the data transmission time is relatively urgent, the additional priority of the first logical channel can be adjusted to a relatively large value compared with the static priority of the first logical channel. , so that it can obtain higher additional priority to preempt resources and meet the low latency requirements of the business.

[0068] The transmission time parameter T corresponding to the first logical channel is greater than or equal to the first time threshold and is less than the second time threshold In the case of , it means that the transmission time parameter T corresponding to the first logical channel is relatively medium, and the additional priority of the first logical channel can be That is to say, when the data transmission time is moderate, the additional priority of the first logical channel can be adjusted to a moderate value compared with the static priority of the first logical channel. , so as to take into account the needs of other businesses and achieve rational allocation and utilization of resources.

[0069] The transmission time parameter T corresponding to the first logical channel is greater than or equal to the third time threshold In the case of , it means that the transmission time parameter T corresponding to the first logical channel is relatively large, and the additional priority of the first logical channel can be That is to say, when the data transmission time is relatively ample, the additional priority of the first logical channel can be adjusted to a relatively small value compared with the static priority of the first logical channel. , to reduce unnecessary resource preemption and improve the fairness of resource allocation.

[0070] Example 2, assume that the reference auxiliary information of the first logical channel includes the transmission time parameter corresponding to the first logical channel and the service type corresponding to the first logical channel. The first indication information can, for example, indicate the mapping relationship between the reference auxiliary information of the first logical channel (including the transmission time parameter corresponding to the first logical channel and the service type corresponding to the first logical channel) and the additional priority of the first logical channel in the form of Table 2: Table 2

[0071] Among them, the urgency of service type A can be greater than that of service type B, or it can be said that the latency requirement of service type A can be higher than that of service type B, or it can be said that the latency budget of service type A can be smaller than that of service type B. The urgency of service type B can be greater than that of service type C, or it can be said that the latency requirement of service type B can be higher than that of service type C, or it can be said that the latency budget of service type B can be smaller than that of service type C. can represent the static priority of the first logical channel, T can represent the transmission time parameter corresponding to the first logical channel, 0 < < , 0 ≤ < < < < .

[0072] When the transmission time parameter T corresponding to the first logical channel is less than the first time threshold , and the service type corresponding to the first logical channel is service type A, the additional priority of the first logical channel can be . That is to say, when the data transmission time is relatively urgent and the service urgency is relatively high, the additional priority of the first logical channel can be relatively high. When the transmission time parameter T corresponding to the first logical channel is greater than or equal to the first time threshold and less than the second time threshold , and the service type corresponding to the first logical channel is service type B, the additional priority of the first logical channel can be . That is to say, when the data transmission time is moderate and the service urgency is moderate, the additional priority of the first logical channel can be moderate. When the transmission time parameter T corresponding to the first logical channel is greater than or equal to the third time threshold , and the service type corresponding to the first logical channel is service type C, the additional priority of the first logical channel can be That is to say, when the data transmission time is relatively abundant and the service urgency is relatively low, the additional priority of the first logical channel can be relatively low.

[0073] In some other embodiments, the first indication information may also be used to directly indicate the additional priority of the first logical channel. For example, the first indication information may directly indicate that the additional priority of the first logical channel is . Optionally, the first indication information may indicate the additional priorities of one or more logical channels, and the one or more logical channels include the first logical channel.

[0074] S202. When the transmission information of the first logical channel meets the triggering condition, the terminal device adjusts the priority of the first logical channel from the static priority to the additional priority of the first logical channel.

[0075] In the embodiments of this application, after receiving the first indication information from the network device, the terminal device may determine the additional priority of the first logical channel according to the first indication information. After the terminal device determines the additional priority of the first logical channel, the additional priority of the first logical channel may not take effect immediately, but take effect only when the transmission information of the first logical channel meets the triggering condition. Here, the effective of the additional priority of the first logical channel can be understood as using the additional priority of the first logical channel to replace the static priority of the first logical channel. Since the additional priority of the first logical channel is higher than the static priority of the first logical channel, in this way, it is possible to flexibly increase the priority of the first logical channel based on the actual data transmission situation of the first logical channel, so as to meet the resource allocation requirements of different services.

[0076] The transmission information of the first logical channel can be understood as the relevant information of the data currently to be transmitted on the first logical channel. The fact that the transmission information of the first logical channel meets the triggering condition may include at least one of the following: the remaining transmission time of the first logical channel is equal to the transmission time parameter corresponding to the first logical channel; the service type corresponding to the first logical channel is a preset service type; the traffic characteristic parameter corresponding to the first logical channel is greater than or equal to a preset traffic characteristic parameter. The fact that the transmission information of the first logical channel meets the triggering condition may indicate that the data on the first logical channel needs to be transmitted preferentially, or in other words, the data on the first logical channel needs to be preferentially allocated transmission resources.

[0077] Among them, the remaining transmission time of the first logical channel being equal to the transmission time parameter corresponding to the first logical channel can indicate that the data transmission of the first logical channel is in a critical state, and if there is additional delay, it may lead to failure to meet the delay requirements specified by the transmission time parameter. That is to say, the data of the first logical channel needs to be preferentially allocated resources to ensure that the data can be transmitted within the remaining time. For example, assuming that the transmission time parameter corresponding to the first logical channel is 10 ms and the initial remaining transmission time of the first logical channel is 30 ms, when the remaining transmission time is reduced from 30 ms to 10 ms, it can be considered that the transmission information of the first logical channel meets the trigger condition.

[0078] The service type corresponding to the first logical channel being a preset service type can indicate that the data of the first logical channel has a certain degree of urgency or importance, and it is necessary to ensure low delay in data transmission. That is to say, the data of the first logical channel needs to be preferentially transmitted to ensure the data transmission efficiency of the preset service type. For example, assuming that the preset service type is the AR service, when the data of the first logical channel is the data corresponding to the AR service, it can be considered that the transmission information of the first logical channel meets the trigger condition.

[0079] The traffic characteristic parameter corresponding to the first logical channel being greater than or equal to the preset traffic characteristic parameter can indicate that the data volume of the first logical channel is large and more transmission resources are needed to support a larger data transmission volume. That is to say, the data of the first logical channel needs to be preferentially allocated resources to meet the requirements of large data volume transmission. For example, assuming that the preset traffic characteristic parameter indicates that the preset data volume corresponding to the first logical channel is the first data volume, when the traffic characteristic parameter corresponding to the first logical channel indicates that the data volume corresponding to the first logical channel is greater than or equal to the first data volume, it can be considered that the transmission information of the first logical channel meets the trigger condition.

[0080] When it is determined that the transmission information of the first logical channel meets the trigger condition, the terminal device can adjust the priority of the first logical channel from the static priority to the additional priority of the first logical channel, thereby ensuring the transmission performance of the first logical channel and achieving more optimized resource allocation.

[0081] S203, based on the additional priority of the first logical channel, send the data corresponding to the first logical channel to the network device.

[0082] In an embodiment of the present application, after the terminal device adjusts the priority of the first logical channel from the static priority to the additional priority of the first logical channel, it can schedule data according to the additional priority of the first logical channel and the available resources. Since the additional priority of the first logical channel is higher than the static priority of the first logical channel, after the priority of the first logical channel is adjusted to the additional priority, compared with the case where the priority of the first logical channel is the static priority, the data corresponding to the first logical channel can be preferentially scheduled.

[0083] Figure 2 In the embodiment shown, the terminal device can determine the additional priority of the first logical channel based on the first indication information sent by the network device, and when the actual transmission situation of the first logical channel meets the trigger condition, raise the priority of the first logical channel from the static priority to the additional priority. In this way, it helps to achieve flexible adjustment of the logical channel priority, thereby improving the rationality of resource allocation and meeting the delay requirements of different services.

[0084] The above Figure 2 describes the overall process of the priority adjustment method provided by the embodiment of the present application. In addition, for the priority adjustment method of the embodiment of the present application, according to different ways of indicating the additional priority of the first logical channel by the first indication information, there can be different implementation manners.

[0085] Please refer to Figure 3 , Figure 3 , which is a schematic flowchart of another priority adjustment method provided by the embodiment of the present application. Figure 3 It mainly describes how to implement the priority adjustment method of the embodiment of the present application when the first indication information is used to indirectly indicate the additional priority of the first logical channel. This method can include but is not limited to the following steps: S301, the network device sends the first indication information to the terminal device. Correspondingly, the terminal device receives the first indication information from the network device.

[0086] When the first indication information is used to indirectly indicate the additional priority of the first logical channel, the first indication information can specifically be used to indicate the mapping relationship between the reference auxiliary information of N logical channels and the additional priority of the N logical channels. Among them, the N logical channels can include the first logical channel. Optionally, the reference auxiliary information of the first logical channel can include at least one of the following: the transmission time parameter corresponding to the first logical channel; the service type corresponding to the first logical channel; the traffic characteristic parameter corresponding to the first logical channel. For the relevant content of the reference auxiliary information, please refer to the specific description in the foregoing text, and details are not described herein again.

[0087] S302, the terminal device determines the additional priority of the first logical channel according to the mapping relationship and the reference auxiliary information of the first logical channel.

[0088] In the embodiment of the present application, after the terminal device receives the first indication information, it may determine the reference auxiliary information of the first logical channel, and then determine the additional priority corresponding to the reference auxiliary information of the first logical channel according to the mapping relationship indicated by the first indication information.

[0089] In a possible implementation, the reference auxiliary information of the first logical channel may include single-item information. For example, the reference auxiliary information of the first logical channel may include the transmission time parameter corresponding to the first logical channel, and the first indication information may indicate the mapping relationship between the transmission time parameter corresponding to the first logical channel and the additional priority of the first logical channel. Exemplarily, the first indication information may indicate the mapping relationship between the transmission time parameter corresponding to the first logical channel and the additional priority of the first logical channel in the form of Table 1 above. It can be seen from Table 1 that different time interval ranges of the transmission time parameter correspond to different additional priorities, so that the terminal device can flexibly select the additional priority of the first logical channel according to the determined transmission time parameter corresponding to the first logical channel. For example, taking Table 1 as an example, assume that in the first time period, the first logical channel transmits data 1, and the transmission time parameter corresponding to data 1 is less than , then the additional priority corresponding to the first logical channel in the first time period may be , where may be the static priority corresponding to data 1; assume that in the second time period, the first logical channel transmits data 2, and the transmission time parameter corresponding to data 2 is greater than , then the additional priority corresponding to the first logical channel in the second time period may be , where may be the static priority corresponding to data 2.

[0090] In a possible implementation, the reference auxiliary information of the first logical channel may include at least two items of information. For example, the reference auxiliary information of the first logical channel may include the transmission time parameter corresponding to the first logical channel and the service type corresponding to the first logical channel. Exemplarily, the first indication information may indicate the mapping relationship between the transmission time parameter corresponding to the first logical channel and the service type corresponding to the first logical channel, and the additional priority of the first logical channel in the form of Table 2 above. It can be seen from Table 2 that different time interval ranges of the transmission time parameter correspond to different additional priorities, and different service types also correspond to different additional priorities, so that the terminal device can flexibly select the additional priority of the first logical channel according to the determined transmission time parameter corresponding to the first logical channel and the service type corresponding to the first logical channel. For example, taking Table 2 as an example, assume that in the third time period, the logical channel transmits data 3, and the transmission time parameter corresponding to data 3 is less than If the service type corresponding to Data 3 is Type A, then the additional priority corresponding to the first logical channel in the third time period can be , where can be the static priority corresponding to Data 3; assume that in the fourth time period, the logical channel transmits Data 4, and the transmission time parameter corresponding to Data 4 is greater than , and the service type corresponding to Data 4 is Type C, then the additional priority corresponding to the first logical channel in the fourth time period can be , where can be the static priority corresponding to Data 4.

[0091] In this way, the terminal device can achieve fine-grained adjustment of the logical channel priority according to the mapping relationship indicated by the first indication information.

[0092] It should be understood that the reference auxiliary information of the first logical channel includes the transmission time parameter corresponding to the first logical channel. The reference auxiliary information of the first logical channel including the transmission time parameter corresponding to the first logical channel and the service type corresponding to the first logical channel is only for illustration and does not constitute a limitation on the embodiments of the present application. In actual implementation, the reference auxiliary information of the first logical channel may include any one or more of the transmission time parameter corresponding to the first logical channel, the service type corresponding to the first logical channel, and the traffic characteristic parameter corresponding to the first logical channel.

[0093] S303. When the transmission information of the first logical channel meets the trigger condition, the terminal device adjusts the priority of the first logical channel from the static priority to the additional priority of the first logical channel.

[0094] S304. Based on the additional priority of the first logical channel, send the data corresponding to the first logical channel to the network device.

[0095] For the relevant content of steps S303 and S304, reference can be made to Figure 2 the specific descriptions of steps S202 and S203 in the corresponding embodiments, which will not be elaborated here.

[0096] Figure 3 In the illustrated embodiment, based on the mapping relationship indicated by the network device, the terminal device can dynamically determine the additional priority of the first logical channel in combination with reference auxiliary information such as the transmission time parameter corresponding to the first logical channel, and when the actual transmission situation of the first logical channel meets the trigger condition, raise the priority of the first logical channel from the static priority to the additional priority. In this way, it helps to achieve fine-grained adjustment of the logical channel priority, thereby improving the rationality of resource allocation and meeting the delay requirements of different services.

[0097] Please refer to Figure 4 ,Figure 4 This is a schematic diagram of the scenario where the terminal device adjusts the static priority of the first logical channel based on the mapping relationship indicated by the first indication information. As Figure 4 shown, after receiving the mapping relationship indicated by the first indication information, the terminal device can determine the reference auxiliary information of the first logical channel, and then determine the additional priority corresponding to the reference auxiliary information of the first logical channel from the mapping relationship as the additional priority of the first logical channel. Furthermore, when the transmission information of the first logical channel meets the trigger condition, the priority of the first logical channel can be adjusted from the static priority to the additional priority of the first logical channel.

[0098] In a possible implementation manner, the first indication information may also directly indicate the additional priority of the first logical channel. Please refer to Figure 5 , Figure 5 which is a schematic flowchart of another priority adjustment method provided by the embodiments of the present application. Figure 5 It mainly describes how to implement the priority adjustment method of the embodiments of the present application when the first indication information is used to directly indicate the additional priority of the first logical channel. The method may include but is not limited to the following steps: Optionally, in S501, the terminal device sends the reference auxiliary information of the first logical channel to the network device. Correspondingly, the network device receives the reference auxiliary information of the first logical channel from the terminal device.

[0099] Step S501 is an optional step, that is, the terminal device may not execute step S501. Optionally, the reference auxiliary information of the first logical channel may include at least one of the following: the transmission time parameter corresponding to the first logical channel; the service type corresponding to the first logical channel; the traffic characteristic parameter corresponding to the first logical channel. For the relevant content of the reference auxiliary information, please refer to the specific description in the foregoing text, and details are not described herein again.

[0100] The terminal device sends the reference auxiliary information of the first logical channel to the network device, so that the network device can more accurately determine the additional priority of the first logical channel according to the reference auxiliary information of the first logical channel.

[0101] S502, the network device determines the additional priority of the first logical channel.

[0102] Among them, the network device can determine the additional priority of the first logical channel according to the real-time network conditions and service requirements, so as to directly indicate the determined additional priority of the first logical channel to the terminal device.

[0103] In a possible implementation, the network device may determine the additional priority of the first logical channel according to the reference auxiliary information of the first logical channel. The manner in which the network device determines the additional priority of the first logical channel according to the reference auxiliary information of the first logical channel may specifically be to first determine the priority adjustment value of the first logical channel according to the reference auxiliary information of the first logical channel, and then adjust the static priority of the first logical channel according to the priority adjustment value of the first logical channel, so as to obtain the additional priority of the first logical channel. Optionally, the smaller the value of the priority, the higher the corresponding priority. The manner of adjusting the static priority of the first logical channel according to the priority adjustment value of the first logical channel may be that the additional priority of the first logical channel minus the priority adjustment value of the first logical channel, and the priority adjustment value of the first logical channel may be a positive integer.

[0104] Optionally, the reference auxiliary information of the first logical channel may include one or more items of information.

[0105] For the case where the reference auxiliary information of the first logical channel includes one item of information, one item of information may correspond to one priority adjustment value or multiple priority adjustment values.

[0106] For example, the reference auxiliary information of the first logical channel may include the transmission time parameter corresponding to the first logical channel. Different transmission time parameters may correspond to different priority adjustment values. For example, the smaller the transmission time parameter, the larger the corresponding priority adjustment parameter may be, and the higher the corresponding additional priority. Or, different transmission time parameters may correspond to the same priority adjustment value. Since the static priorities corresponding to different transmission time parameters may be different, for example, the smaller the transmission time parameter, the higher the corresponding static priority, so uniformly adjusting the same priority adjustment value can satisfy that the smaller the transmission time parameter, the higher the corresponding additional priority.

[0107] Another example is that the reference auxiliary information of the first logical channel may include the service type corresponding to the first logical channel. Different service types may correspond to different priority adjustment values. For example, for a service type with a higher delay requirement, the corresponding priority adjustment parameter may be larger, and the corresponding additional priority is higher. Or, different service types may correspond to the same priority adjustment value. Since the static priorities corresponding to different service types may be different, for example, for a service type with a higher delay requirement, the corresponding static priority may be higher, so uniformly adjusting the same priority adjustment value can satisfy that for a service type with a higher delay requirement, the corresponding additional priority is higher.

[0108] For another example, the reference auxiliary information of the first logical channel may include traffic characteristic parameters corresponding to the first logical channel. Different traffic characteristic parameters may correspond to different priority adjustment values. For example, for a traffic characteristic parameter indicating a larger data volume, the corresponding priority adjustment parameter may be larger, and the corresponding additional priority is higher. Alternatively, different traffic characteristic parameters may correspond to the same priority adjustment value. Since the static priorities corresponding to different traffic characteristic parameters may be different, for example, for a traffic characteristic parameter indicating a larger data volume, the corresponding static priority may be higher. Therefore, uniformly adjusting the same priority adjustment value can satisfy the requirement that for a traffic characteristic parameter indicating a larger data volume, the corresponding additional priority is higher.

[0109] Exemplarily, taking the reference auxiliary information of the first logical channel including the service type corresponding to the first logical channel as an example, the additional priorities corresponding to different service types may be as shown in Table 3: Table 3

[0110] Among them, may represent the static priority corresponding to the data of service type A, may represent the static priority corresponding to the data of service type B, may represent the static priority corresponding to the data of service type C, , and are all different, that is, ≠ ≠ . The urgency of service type A may be greater than that of service type B, or it can be said that the latency requirement of service type A is higher than that of service type B, or it can be said that the latency budget of service type A is smaller than that of service type B. The urgency of service type B may be greater than that of service type C, or it can be said that the latency requirement of service type B is higher than that of service type C, or it can be said that the latency budget of service type B is smaller than that of service type C. For example, service type A may be an interactive VR service type. The latency requirement of interactive VR is very high, and it is necessary to quickly and accurately feedback the user's interaction in the virtual environment; service type B may be a real-time MR collaboration service type. The latency requirement of real-time MR collaboration is relatively high. It involves real-time interaction among multiple users and needs to respond to the user's actions and instructions in a timely manner to achieve a smooth collaboration experience; service type C may be a VR on-demand service type. VR on-demand has relatively low latency requirements because it is mainly a one-way data stream and has less demand for real-time interaction than the previous two. , and may represent the priority adjustment values.

[0111] Optionally, , and can be the same, that is, = = . That is to say, the static priorities corresponding to service type A, the static priorities corresponding to service type B, and the static priorities corresponding to service type C can be uniformly adjusted by the same priority adjustment value, so as to obtain the additional priorities corresponding to service type A, the additional priorities corresponding to service type B, and the static priorities corresponding to service type C.

[0112] Optionally, , and can also be different, such as . That is to say, the static priorities of different service types can be adjusted by different priority adjustment values, and the higher the delay requirement of the service type, the larger the corresponding priority adjustment value, and the higher the corresponding additional priority.

[0113] For the case where the reference auxiliary information of the first logical channel includes multiple pieces of information, the multiple pieces of information can correspond to the same priority adjustment value, or can respectively correspond to different priority adjustment values.

[0114] For example, the reference auxiliary information of the first logical channel may include the transmission time parameter corresponding to the first logical channel and the service type corresponding to the first logical channel. The additional priorities corresponding to different transmission time parameters and the additional priorities corresponding to different service types can be as shown in Table 4: Table 4

[0115] Among them, can represent the static priority corresponding to the data of service type A and the transmission time parameter satisfying T < , can represent the static priority corresponding to the data of service type B and the transmission time parameter satisfying ≤T < , can represent the static priority corresponding to the data of service type C and the transmission time parameter satisfying T≥ . , and are all different, such as < < (taking the smaller the value, the higher the priority as an example). Optionally, , and can be the same, that is, = = or 、 and may also be different, such as > > 。

[0116] For another example, the reference auxiliary information of the first logical channel may include the service type corresponding to the first logical channel and the traffic characteristic parameters corresponding to the first logical channel. The additional priorities corresponding to different service types and the additional priorities corresponding to different traffic characteristic parameters may be as shown in Table 5: Table 5

[0117] Among them, may represent the static priority corresponding to data of service type A and with a data volume greater than s, may represent the static priority corresponding to data of service type A and with a data volume less than or equal to s, may represent the static priority corresponding to data of service type B and with a data volume greater than s, may represent the static priority corresponding to data of service type B and with a data volume less than or equal to s, may represent the static priority corresponding to data of service type C and with a data volume greater than s, may represent the static priority corresponding to data of service type C and with a data volume less than or equal to s. The static priorities of the same service type may be the same, that is = = , = ,and the static priorities of different service types may be different, such as < < (taking the case where the smaller the value, the higher the priority). Optionally, 、 、 、 、 、 may be the same, that is = = = = = or 、 、 、 、 、 may also be different, such as > > > > > 。

[0118] In a possible implementation, the network device may determine a priority adjustment value of the first logical channel according to the reference auxiliary information of the first logical channel and a preset model. Optionally, the preset model may be a linear model or a non-linear model, which is not limited in this application. Taking the preset model as a linear model as an example, the priority adjustment value of the first logical channel may satisfy the following formula, for example:

[0119] where T may represent a transmission time parameter corresponding to the first logical channel, may represent a proportionality coefficient corresponding to T, D may represent a delay budget of the service type corresponding to the first logical channel, may represent a proportionality coefficient corresponding to D, B may represent a traffic characteristic parameter corresponding to the first logical channel, may represent a proportionality coefficient corresponding to B. 、 and can be flexibly adjusted according to actual requirements.

[0120] In a possible implementation, the network device may also determine the priority adjustment value of the first logical channel in combination with the current network load and congestion situation. For example, in a congested situation, for the case where the transmission time parameter corresponding to the first logical channel is small, or the delay budget of the service type corresponding to the first logical channel is small, or the traffic characteristic parameter corresponding to the first logical channel is large, the network device may determine a higher priority adjustment value, so that the first logical channel can obtain a higher additional priority to meet the service requirements.

[0121] S503. The network device sends first indication information to the terminal device. Correspondingly, the terminal device receives the first indication information from the network device.

[0122] In the embodiment of this application, after determining the additional priority of the first logical channel, the network device may send first indication information to the terminal device, and the first indication information may be used to directly indicate the additional priority of the first logical channel, which is beneficial to improving the processing efficiency of the terminal device.

[0123] S504. When the transmission information of the first logical channel meets the trigger condition, the terminal device adjusts the priority of the first logical channel from the static priority to the additional priority of the first logical channel.

[0124] S505. Send the data corresponding to the first logical channel to the network device based on the additional priority of the first logical channel.

[0125] For the relevant content of steps S504 and S505, reference can be made to Figure 2 the specific descriptions of steps S202 and S203 in the corresponding embodiments, which will not be elaborated here.

[0126] Figure 5 In the illustrated embodiment, based on the additional priority of the first logical channel indicated by the network device, the terminal device can more quickly determine the additional priority, and when the actual transmission situation of the first logical channel meets the triggering condition, the priority of the first logical channel can be upgraded from the static priority to the additional priority. In this way, it helps to achieve flexible adjustment of the logical channel priority, thereby improving the rationality of resource allocation and meeting the delay requirements of different services.

[0127] Please refer to Figure 6 , Figure 6 is a schematic diagram of the scenario where the terminal device adjusts the static priority of the first logical channel based on the additional priority of the first logical channel indicated by the first indication information. As Figure 6 shown, based on the received first indication information, the terminal device can obtain the additional priority of the first logical channel. Then, when the transmission information of the first logical channel meets the triggering condition, the priority of the first logical channel can be adjusted from the static priority to the additional priority of the first logical channel.
