Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method, device, and storage medium. Background Art

[0002] In the uplink data transmission process of the fifth generation mobile communication technology (5G), user equipment (UE) needs to obtain uplink transmission authorization through a scheduling request (SR) or random access (RA) process. When the UE has uplink data to be sent, if the UE is configured with the physical uplink control channel (PUCCH) resources of the SR, the UE sends an SR request.

[0003] SR resource management plays an important role in 5G networks. Existing SR configurations generally use static resource pools. In high-load scenarios, such as intensified resource competition, this can easily lead to delays in UE scheduling uplink resources. In low-load scenarios, fixed resource occupation causes resource waste. Summary of the Invention

[0004] The present application provides a communication method, device, and storage medium to achieve elastic scaling of scheduling request (SR) resources, ensure service reliability, and reduce communication overhead.

[0005] In a first aspect, a communication method is provided. This method can be performed, for example, by a network device, or by a component configured within the network device (such as a circuit, chip, or chip system). It can also be implemented by a logic module or software that implements all or part of the network device's functionality. This application is not limited to this. The following description uses a network device (such as a satellite) as an example.

[0006] The method includes: when a first scheduling request SR resource pool meets a first condition, sending activation indication information, the activation indication information is used by the terminal device to activate a second scheduling request SR resource pool; wherein the resource configuration of the physical uplink control channel corresponding to the first scheduling request SR resource pool is different from the resource configuration of the physical uplink control channel corresponding to the second scheduling request SR resource pool.

[0007] Among them, the first scheduling request SR resource pool and the second scheduling request SR resource pool include physical uplink control channel (PUCCH) resources. The terminal device can send a scheduling request (SR) based on the first scheduling request SR resource pool or the second scheduling request SR resource pool to request resources for transmitting uplink data.

[0008] It is understandable that the network device can pre-configure a first scheduling request SR resource pool and a second scheduling request SR resource pool, wherein the PUCCH resource configuration corresponding to the first scheduling request SR resource pool is different from the PUCCH resource configuration corresponding to the second scheduling request SR resource pool.

[0009] It should be noted that the embodiments of the present application do not specifically limit the PUCCH resource configuration corresponding to the first scheduling request SR resource pool and the PUCCH resource configuration corresponding to the second scheduling request SR resource pool. Those skilled in the art can make corresponding configurations based on actual communication service requirements. Exemplarily, the first scheduling request SR resource pool is configured as a resource pool with a fixed resource period, frequency domain position, and format, which is used to adapt to steady-state load scenarios; the second scheduling request SR resource pool is configured as a resource pool with a higher resource density or a shorter period, supports dynamic expansion, and is used to adapt to burst traffic scenarios.

[0010] The first condition is not specifically limited in the embodiments of the present application, and those skilled in the art may configure it accordingly based on specific service requirements. Optionally, the first condition includes: resource utilization of the first scheduling request SR resource pool is greater than a threshold, and / or service congestion occurs in the first scheduling request SR resource pool.

[0011] In the above implementation method, the network device can detect the operating status of the first scheduling request SR resource pool, and activate the second scheduling request SR resource pool when the first scheduling request SR resource pool meets the preset operating status conditions, so that the terminal device can use the resources of the first scheduling request SR resource pool and the second scheduling request SR resource pool to perform resource scheduling for uplink data transmission, thereby realizing elastic scaling of scheduling request resources, ensuring the reliability of communication services, and reducing communication overhead.

[0012] In a possible implementation manner of the first aspect, the activation indication information is carried in downlink control information DCI.

[0013] In the above implementation, a method for sending activation indication information is provided. Among them, the network device can send activation indication information based on downlink control information (DCI). Optionally, the activation instruction field can be carried in the field of DCI. For example: in the DCI 0_1 format, a 1-bit field is configured as a flag bit of the activation instruction, and the activation instruction for the second scheduling request SR resource pool is identified based on the flag bit. For example: when the flag bit is 1, the activation indication information is indicated. In the embodiment of the present application, no specific limitation is made on how the activation indication information is carried in the DCI.

[0014] In a possible implementation manner of the first aspect, the activation indication information is specifically used by the terminal device to activate the second scheduling request SR resource pool within a first timing duration.

[0015] Specifically, in addition to indicating the activation of the second scheduling request SR resource pool, the activation indication information is also used to indicate the activation duration of the second scheduling request SR resource pool. The second scheduling request SR resource pool corresponds to the first timer, and the first timer is used to activate the second scheduling request SR resource pool within the first timing duration. Optionally, the first timing duration field can be carried in the DCI field. For example, in the DCI 0_1 format, a 2-bit field is configured as the first timing duration field. For example, when the first timing duration field is 3, it indicates that the first timing duration is 3 time slots. In the above implementation method, the activation indication information can realize the activation control of the second scheduling request SR resource pool within the first timing duration. When the first timing duration ends, the second scheduling request SR resource pool automatically falls back to the inactive state, thereby realizing the elastic scaling of the scheduling request resources, preventing resource leakage, ensuring the reliability of communication services, and reducing communication overhead.

[0016] In a possible implementation manner of the first aspect, the sending of activation indication information includes sending activation indication information at least twice, where the activation indication information is also used to reset the first timing duration.

[0017] Specifically, the embodiment of the present application also provides a refresh mechanism for the first timing duration, that is, within the first timing duration, if the terminal device receives activation indication information again, the terminal device can reset the first timer, that is, reset the first timing duration, so that the network device can reset the activation duration of the second scheduling request SR resource pool based on the latest operating status of the first scheduling request SR resource pool, so that the embodiment of the present application is adaptable to continuous high-load scenarios.

[0018] In a possible implementation manner of the first aspect, the method further includes: sending resource pool configuration information based on radio resource control RRC signaling, where the resource pool configuration information is used to configure the first scheduling request SR resource pool and the second scheduling request SR resource pool.

[0019] Specifically, the network device may configure the PUCCH resources corresponding to the first scheduling request SR resource pool and the second scheduling request SR resource pool based on radio resource control (RRC) signaling. For example, the period and corresponding PUCCH resources of the first scheduling request SR resource pool may be configured through the RRC parameter normalSR-Config, and the period and corresponding PUCCH resources of the second scheduling request SR resource pool may be configured through the RRC parameter additionalSR-Config. It should be noted that the second scheduling request SR resource pool is in an inactive state by default under initial configuration.

[0020] In a possible implementation manner of the first aspect, the resource pool configuration information is further used to configure a first timing duration, where the first timing duration is associated with an activation duration of the second scheduling request SR resource pool.

[0021] Specifically, the network device can also configure the first timing duration through the resource pool configuration information, that is, configure the first timing duration through RRC signaling. Exemplarily, the network device can configure the first timing duration through RRC signaling. For example: the first timing duration is configured at the same time when configuring the second scheduling request SR resource pool through the RRC parameter additionalSR-Config. Another example: the first timing duration is updated through the RRC reconfiguration message. This is not limited in the embodiments of the present application.

[0022] In a possible implementation manner of the first aspect, the method further includes: sending priority indication information, where the priority indication information is used to indicate the priority between the first scheduling request SR resource pool and the second scheduling request SR resource pool.

[0023] It is understandable that when the second scheduling request SR resource pool is activated, the terminal device can use the first scheduling request SR resource pool for uplink resource scheduling, and can also use the second scheduling request SR resource pool for uplink resource scheduling. The network device can indicate to the terminal through the priority indication information which scheduling request SR resource pool to use for uplink resource scheduling. Exemplarily, a 1-bit field can be configured through DCI as a flag bit for priority indication, and the priority of the scheduling request SR resource pool is determined based on the flag bit. For example: when the flag bit is 1, it indicates that the priority of the second scheduling request SR resource pool is higher than the priority of the first scheduling request SR resource pool. At this time, the terminal device gives priority to using the resources of the second scheduling request SR resource pool for uplink resource scheduling. For another example: when the flag bit is 0, it indicates that the priority of the first scheduling request SR resource pool is higher than the priority of the second scheduling request SR resource pool. At this time, the terminal device gives priority to using the resources of the first scheduling request SR resource pool for uplink resource scheduling. The specific configuration method of the priority indication information is not limited in the embodiment of the present application.

[0024] In the above implementation, network devices can configure the priority of the second scheduling request (SR) resource pool to be higher than the priority of the first scheduling request (SR) resource pool based on real-time network load conditions, for example, in scenarios with bursty ultra-reliable low latency communications (URLLC) traffic. This allows terminal devices to utilize the resources in the second scheduling request (SR) resource pool for uplink resource scheduling, ensuring the timeliness and reliability of uplink scheduling. The priority of the scheduling request resource pool can thus be dynamically adjusted using priority indication information to adapt to uplink scheduling requirements in different service scenarios, ensuring priority scheduling of critical services.

[0025] In a second aspect, a communication method is provided. This method can be executed, for example, by a terminal device, or by a component configured in the terminal device (such as a circuit, chip, or chip system), or by a logic module or software that implements all or part of the terminal device's functions. This application is not limited to this. The following description uses a terminal device as an example.

[0026] The method includes: receiving activation indication information sent by a network device when a first scheduling request SR resource pool meets a first condition; activating a second scheduling request SR resource pool based on the activation indication information, wherein the resource configuration of the physical uplink control channel corresponding to the first scheduling request SR resource pool is different from the resource configuration of the physical uplink control channel corresponding to the second scheduling request SR resource pool.

[0027] In a possible implementation manner of the second aspect, the activation indication information is carried in downlink control information DCI.

[0028] In a possible implementation manner of the second aspect, activating the second scheduling request SR resource pool based on the activation indication information includes: activating the second scheduling request SR resource pool within a first timing duration based on the activation indication information.

[0029] In a possible implementation manner of the second aspect, the method further includes: if the activation indication information is received again within the first timing duration, resetting the first timing duration.

[0030] In a possible implementation of the second aspect, the method further includes: obtaining resource pool configuration information sent by the network device based on radio resource control RRC signaling; and configuring the first scheduling request SR resource pool and the second scheduling request SR resource pool based on the resource pool configuration information.

[0031] In a possible implementation manner of the second aspect, the resource pool configuration information is further used to configure a first timing duration, where the first timing duration is associated with an activation duration of the second scheduling request SR resource pool.

[0032] In a possible implementation manner of the second aspect, the method further includes: obtaining priority indication information, where the priority indication information is used to indicate the priority between the first scheduling request SR resource pool and the second scheduling request SR resource pool.

[0033] In a possible implementation manner of the second aspect, the first condition includes: a resource utilization rate of the first scheduling request SR resource pool is greater than a threshold, and / or a service of the first scheduling request SR resource pool is congested.

[0072] 1. Scheduling request (SR) resource pool

[0073] The SR resource pool includes physical uplink control channel (PUCCH) resources. A terminal device can send a scheduling request (SR) based on the SR resource pool to request resources for transmitting uplink data.

[0074] In an embodiment of the present application, the SR resource pool includes a first SR resource pool and a second SR resource pool. The resource configuration of the physical uplink control channel corresponding to the first SR resource pool is different from the resource configuration of the physical uplink control channel corresponding to the second SR resource pool. The first SR resource pool can also be called a normal SR resource pool, and the second SR resource pool can also be called a backup SR resource pool.

[0075] The first and second SR resource pools can be pre-configured via RRC signaling. For example, the period and corresponding PUCCH resources of the first SR resource pool are configured via the RRC parameter normalSR-Config, and the period and corresponding PUCCH resources of the second SR resource pool are configured via the RRC parameter additionalSR-Config. The second SR resource pool is in an inactive state by default in the initial configuration.

[0076] It should be noted that the embodiments of the present application do not make specific limitations on the PUCCH resource configuration corresponding to the first SR resource pool and the PUCCH resource configuration corresponding to the second SR resource pool. Those skilled in the art can make corresponding configurations based on actual communication service requirements.

[0077] Exemplarily, the first SR resource pool is configured as a resource pool with a fixed resource period, frequency domain location, and format to accommodate steady-state load scenarios and meet basic uplink resource request requirements. Exemplarily, the second SR resource pool is configured as a resource pool with a higher resource density or a shorter period, supporting dynamic expansion to accommodate bursty traffic scenarios and ensure low-latency, high-reliability uplink resource requests. For example, the resource period of the first SR resource pool is configured as 20 time slots, and the resource period of the second SR resource pool is configured as 5 time slots.

[0078] It should be understood that the technical terms in this application are for illustration only and are not intended to limit the scope of the present invention. For example, as technology evolves, technical terms may also change. In the case of the same technical meaning, other technical terms should also apply to this application.

[0079] In the uplink data transmission process of the fifth generation mobile communication technology (5G), user equipment (UE) needs to obtain uplink transmission authorization through a scheduling request (SR) or random access (RA) process. When the UE has uplink data to be sent, if the UE is configured with the physical uplink control channel (PUCCH) resources of the SR, the UE sends an SR request.

[0080] SR resource management plays an important role in 5G networks. Existing SR configurations generally use static resource pools. In high-load scenarios, such as intensified resource competition, this can easily lead to delays in UE scheduling uplink resources. In low-load scenarios, fixed resource occupation causes resource waste.

[0081] In view of this, the present application provides a communication method to achieve elastic scaling of scheduling request SR resources, ensure service reliability, and reduce communication overhead.

[0082] The following describes the solution provided by this application in detail in conjunction with the corresponding flowcharts. It will be understood that the schematic flowcharts provided in this application primarily use different devices (e.g., terminal devices, network devices) as examples of the execution entities of the interaction diagrams to illustrate the method, but this application does not limit the execution entities of the interaction diagrams. For example, the device (e.g., terminal device, network device) in the schematic flowcharts may also be a chip, chip system, or processor that supports the device to implement the method, or may be a logic module or software that can implement all or part of the functions of the device.

[0083] For a unified explanation here, in the interaction process of the embodiment of the present application, the message or signaling interaction involved can adopt the message or signaling in the standard, or it can be a newly introduced message or signaling, and the embodiment of the present application does not make specific limitations on this.

[0084] Figure 2 This is a flow chart of a communication method according to an embodiment of the present application. Figure 2 The terminal device in can be Figure 1 Any terminal device in the network can also refer to a device in the terminal device (such as a processor, chip, or chip system, etc.). A network device can be Figure 1 Any access network device in the access network device may also refer to a device in the access network device (such as a processor, chip, or chip system, etc.). Figure 2 As shown, the method includes the following steps:

[0085] Step S200: The network device sends resource pool configuration information based on radio resource control RRC signaling; accordingly, the terminal device receives the resource configuration information, and the terminal resource pool configuration information is used to configure the first scheduling request SR resource pool and the second scheduling request SR resource pool.

[0086] Specifically, the network device may configure the PUCCH resources corresponding to the first scheduling request SR resource pool and the second scheduling request SR resource pool based on radio resource control (RRC) signaling.

[0087] Among them, the resource configuration of the physical uplink control channel corresponding to the first scheduling request SR resource pool is different from the resource configuration of the physical uplink control channel corresponding to the second scheduling request SR resource pool. Under the initial configuration, the second scheduling request SR resource pool is in an inactive state by default.

[0088] It should be noted that the configuration method of the first scheduling request SR resource pool and the second scheduling request SR resource pool can be found in the above term explanation part and will not be repeated here.

[0089] Step S201: When the first scheduling request SR resource pool meets the first condition, the network device sends activation indication information; correspondingly, the terminal device receives the activation indication information, and the activation indication information is used by the terminal device to activate the second scheduling request SR resource pool.

[0090] Among them, the network device can detect the operation status of the first scheduling request SR resource pool, and determine whether the second scheduling request SR resource pool needs to be activated based on the operation status of the first scheduling request SR resource pool. Specifically, when the operation status of the first scheduling request SR resource pool meets the first condition, the network device sends an activation indication message to the terminal device, and after receiving the activation indication message sent by the network device, the terminal device activates the second scheduling request SR resource pool.

[0091] It should be noted that the first scheduling request SR resource pool is activated by default in the initial configuration, that is, the terminal device can use the resources of the first scheduling request SR resource pool to make a scheduling request SR to obtain resources for transmitting uplink data. Activating the second scheduling request SR resource pool means that the PUCCH resources corresponding to the second scheduling request SR resource pool are allowed to be used, and the terminal device can make a scheduling request SR based on the second scheduling request SR resource pool to obtain resources for transmitting uplink data.

[0092] In the above implementation, the network device activates the second scheduling request SR resource pool based on the operating status of the first scheduling request SR resource pool, so that the terminal device can use the resources of the first scheduling request SR resource pool and the second scheduling request SR resource pool to perform resource scheduling for uplink data transmission, thereby realizing elastic scaling of scheduling request resources, ensuring communication service reliability, and reducing communication overhead.

[0093] In an optional implementation, the first condition includes: resource utilization of the first scheduling request SR resource pool is greater than a threshold, and / or service congestion occurs in the first scheduling request SR resource pool.

[0094] The network device may determine whether to activate the second scheduling request SR resource pool based on the resource utilization rate of the first scheduling request SR resource pool and the service operation status.

[0095] It should be noted that the first condition may be pre-configured by the network device. The embodiment of the present application does not make specific limitations on the first condition, and those skilled in the art may make corresponding settings based on specific business requirements.

[0096] In an optional implementation manner, the activation indication information is carried in downlink control information DCI.

[0097] The network device may send activation indication information based on downlink control information (DCI).

[0098] Optionally, an activation instruction field can be carried in the DCI field. For example: in the DCI 0_1 format, a 1-bit field is configured as a flag bit for the activation instruction, and the activation instruction for the second scheduling request SR resource pool is identified based on the flag bit, for example: when the flag bit is 1, the activation instruction information is indicated.

[0099] It should be understood that the activation indication information can also be indicated through other fields of the DCI, including existing fields or newly added fields. The embodiments of the present application do not make specific limitations on how the activation indication information is carried in the DCI.

[0100] In an optional implementation, the activation indication information is specifically used by the terminal device to activate the second scheduling request SR resource pool within the first timing duration.

[0101] Specifically, in addition to indicating the activation of the second scheduling request SR resource pool, the activation indication information is also used to indicate the activation duration of the second scheduling request SR resource pool. The second scheduling request SR resource pool corresponds to the first timer, and the first timer is used to activate the second scheduling request SR resource pool within the first timing duration. In other words, after receiving the activation indication information, the terminal device triggers the first timer to activate the second scheduling request SR resource pool within the first timing duration. When the first timer times out, it triggers the disabling of the second scheduling request SR resource pool. In this way, dynamic management of the second scheduling request SR resource pool is achieved by introducing a timer. After the timer times out, the second scheduling request SR resource pool is automatically closed (falls back to an inactive state) to prevent resource leakage.

[0102] Optionally, the first timing duration field can be carried in the DCI field. For example: in the DCI 0_1 format, a 2-bit field is configured as the first timing duration field. For example: when the first timing duration field is 3, it indicates that the first timing duration is 3 time slots; when the first timing duration field is 2, it indicates that the first timing duration is 2 time slots.

[0103] In an optional implementation, the activation indication information is also used to reset the first timing duration.

[0104] Specifically, within the first timing duration (the second SR resource pool is in an activated state), if the terminal device receives activation indication information again, the terminal device can reset the first timer, that is, reset the first timing duration, and the network device can reset the activation duration of the second scheduling request SR resource pool based on the latest operating status of the first scheduling request SR resource pool, thereby providing a refresh mechanism for the first timing duration, so that the embodiment of the present application is adaptable to continuous high-load scenarios.

[0105] In an optional implementation, the resource pool configuration information is further used to configure a first timing duration, where the first timing duration is associated with an activation duration of the second scheduling request SR resource pool.

[0106] Specifically, the network device can also configure the first timing duration through the resource pool configuration information, that is, configure the first timing duration through RRC signaling. Exemplarily, the network device can configure the first timing duration through RRC signaling. For example: the first timing duration is configured at the same time when the second scheduling request SR resource pool is configured through the RRC parameter additionalSR-Config. Another example: the first timing duration is updated through the RRC reconfiguration message, which is not limited in the embodiments of the present application. This provides another configuration method and update method for the first timing duration to meet the latency requirements in different business scenarios.

[0107] In an optional implementation, the communication method provided in an embodiment of the present application further includes: sending priority indication information, where the priority indication information is used to indicate the priority between the first scheduling request SR resource pool and the second scheduling request SR resource pool.

[0108] Specifically, when the second scheduling request SR resource pool is activated, the terminal device can use the first scheduling request SR resource pool for uplink resource scheduling, or use the second scheduling request SR resource pool for uplink resource scheduling. The network device can indicate which scheduling request SR resource pool to use for uplink resource scheduling through priority indication information.

[0109] Exemplarily, a 1-bit field SR-Priority can be configured through DCI as a flag bit for priority indication, and the priority of the scheduling request SR resource pool can be determined based on the flag bit. For example: when the flag bit is 1, it indicates that the priority of the second scheduling request SR resource pool is higher than the priority of the first scheduling request SR resource pool. At this time, the terminal device gives priority to using the resources of the second scheduling request SR resource pool for uplink resource scheduling. For another example: when the flag bit is 0, it indicates that the priority of the first scheduling request SR resource pool is higher than the priority of the second scheduling request SR resource pool. At this time, the terminal device gives priority to using the resources of the first scheduling request SR resource pool for uplink resource scheduling. The specific configuration method of the priority indication information is not limited in the embodiments of the present application.

[0110] It should be understood that the priority indication information can also be indicated through other fields of the DCI, including existing fields or newly added fields. The embodiments of the present application do not make specific limitations on how the priority indication information is carried in the DCI.

[0111] In the above implementation, network devices can configure the priority of the second scheduling request (SR) resource pool to be higher than the priority of the first scheduling request (SR) resource pool based on real-time network load conditions, for example, in scenarios with bursty ultra-reliable low latency communications (URLLC) traffic. This allows terminal devices to utilize the resources in the second scheduling request (SR) resource pool for uplink resource scheduling, ensuring the timeliness and reliability of uplink scheduling. This allows the priority of the scheduling request resource pool to be dynamically adjusted using priority indication information, flexibly adapting to uplink scheduling requirements in different service scenarios and ensuring priority scheduling of critical services.

[0112] The following combination Figure 3 The flowchart of another communication method shown illustrates the communication method provided in the embodiment of the present application.

[0113] First, the network device pre-configures the first scheduling request SR resource pool and the second scheduling request SR resource pool based on the RRC message. After the initial configuration, the first scheduling request SR resource pool is in the activated state by default, and the second scheduling request SR resource pool is in the inactivated state by default.

[0114] Then, when the first scheduling request SR resource pool is in a low-load state, the terminal device uses the first scheduling request SR resource pool to perform uplink resource scheduling.

[0115] Then, when the network device detects that the first scheduling request SR resource pool is in a high load state (the load is higher than the threshold and / or the service is congested), the network device sends an activation indication message to activate the second SR resource pool and synchronously triggers the first timer.

[0116] Finally, the terminal device detects whether the first timer has timed out. When the first timer times out, the second SR resource pool is disabled and only the first SR resource pool is used for uplink resource scheduling. When the first timer has not timed out, the second SR resource pool is kept activated.

[0117] The above process demonstrates that this embodiment provides a solution for dynamically activating the SR resource pool. Network devices can decide whether to enable backup SR resources based on real-time network load, achieving elastic resource scaling. A timer is introduced to manage the activation duration of the backup SR resource pool, automatically shutting it down after a timeout to prevent resource leakage. The timer duration can be configured and adjusted by the network device, supporting flexible adaptation to the latency requirements of different scenarios. The timer is also refreshable, adapting to scenarios with sustained high loads.
