Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a communication method, apparatus, and storage medium. Background Art

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

[0003] SR resource management plays an important role in the 5G network. The existing SR configuration is generally a static resource pool configuration. In high-load scenarios, such as when resource competition intensifies, it is easy to cause delays in the UE's scheduling of uplink resources. In low-load scenarios, fixed resource occupancy results in resource waste. Summary of the Invention

[0004] This application provides a communication method, apparatus, and storage medium, which realizes the elastic expansion and contraction of scheduling request (SR) resources, ensures service reliability, and reduces communication overhead.

[0005] In a first aspect, a communication method is provided. This method can be executed, for example, by a network device, or by a component (such as a circuit, chip, or chip system, etc.) configured in the network device, or by a logic module or software that can implement all or part of the functions of the network device. This application does not limit this. Hereinafter, a network device (such as a satellite) is taken as an example for description.

[0006] The method includes: sending activation indication information under the condition that a first scheduling request (SR) resource pool meets a first condition, where the activation indication information is used for a 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 can be understood that the network device can pre-configure the first scheduling request (SR) resource pool and the second scheduling request (SR) resource pool. Among them, 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 in the embodiments of this application, no specific limitations are imposed on 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 the steady-state load scenario; the second scheduling request (SR) resource pool is configured as a resource pool with a higher resource density or a shorter period, which supports dynamic expansion and is used to adapt to the burst traffic scenario.

[0010] Among them, no specific limitations are imposed on the first condition in the embodiments of this application. Those skilled in the art can make corresponding settings in combination with specific service requirements. Optionally, the first condition includes: the resource utilization rate of the first scheduling request (SR) resource pool is greater than a threshold, and / or, congestion occurs in the services of the first scheduling request (SR) resource pool.

[0011] In the above implementation, the network device can detect the operating state of the first scheduling request (SR) resource pool. When the first scheduling request (SR) resource pool meets the preset operating state conditions, the second scheduling request (SR) resource pool is activated, 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 for resource scheduling of uplink data transmission, thereby realizing the elastic expansion and contraction of scheduling request resources, ensuring the reliability of communication services, and reducing communication overhead.

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

[0013] In the above implementation, a method for sending activation indication information is provided. Among them, the network device may send activation indication information based on downlink control information (DCI). Optionally, an activation instruction field may be carried in the DCI field. Exemplarily, in the DCI 0_1 format, a 1-bit field is configured as the flag bit of the activation instruction, and the activation instruction for the second scheduling request (SR) resource pool is identified based on this flag bit. For example, when the flag bit is 1, it indicates the activation indication information. In the embodiments 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 for the terminal device to activate the second scheduling request (SR) resource pool within a first timing duration.

[0015] Specifically, the activation indication information is used not only to indicate the activation of the second scheduling request (SR) resource pool, but also to indicate the activation duration of the second scheduling request (SR) resource pool. The second scheduling request (SR) resource pool corresponds to a first timer, and the first timer is used to activate the second scheduling request (SR) resource pool within a first timing duration. Optionally, a first timing duration field may be carried in the DCI field. Exemplarily, 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, 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 reverts to the non-activated 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 the activation indication information includes: sending the activation indication information at least twice, and the activation indication information is also used to reset the first timing duration.

[0017] Specifically, the embodiments of the present application also provide a refreshing mechanism for the first timing duration, that is, within the first timing duration, if the terminal device receives the activation indication information again, the terminal device may reset the first timer, that is, reset the first timing duration. Thus, the network device may reset the activation duration of the second scheduling request (SR) resource pool based on the latest operating state of the first scheduling request (SR) resource pool, so that the embodiments of the present application are adapted to high-load scenarios with high persistence.

[0018] In a possible implementation 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 SR resource pool.

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

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

[0021] Specifically, the network device may 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 may configure the first timing duration through RRC signaling. For example, the first timing duration is configured through the RRC parameter additionalSR-Config when configuring the second SR resource pool. Another example is to update the first timing duration through an RRC reconfiguration message. There is no limitation in the embodiments of the present application.

[0022] In a possible implementation 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 SR resource pool and the second SR resource pool.

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

[0024] In the above implementation, the network device can, based on the real-time network load situation, for example, in a scenario with ultra-reliable low latency communications (URLLC) burst traffic, configure the priority of the second scheduling request SR resource pool to be higher than that of the first scheduling request SR resource pool. Thus, the terminal device can use the resources of the second scheduling request SR resource pool for uplink resource scheduling to ensure the timeliness and reliability of uplink scheduling. Therefore, the priority of the scheduling request resource pool can be dynamically adjusted through the priority indication information to adapt to the uplink scheduling requirements in different service scenarios and ensure that critical services are scheduled first.

[0025] In a second aspect, a communication method is provided. This method can be executed, for example, by a terminal device, or can also be executed by components (such as circuits, chips, or chip systems, etc.) configured in the terminal device, or can also be implemented by a logic module or software that can implement all or part of the functions of the terminal device. The present application does not limit this. The following description is given by taking the terminal device as an example.

[0026] The method includes: receiving activation indication information sent by the network device when the first scheduling request SR resource pool meets a first condition; activating the second scheduling request SR resource pool based on the activation indication information, where 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 of the second aspect, the activation indication information is carried in the downlink control information DCI.

[0028] In a possible implementation 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 of the second aspect, the method further includes: within the first timing duration, if the activation indication information is received again, 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; 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 of the second aspect, the resource pool configuration information is further used to configure a first timing duration, and the first timing duration is associated with the activation duration of the second scheduling request (SR) resource pool.

[0032] In a possible implementation 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 of the second aspect, the first condition includes: the resource utilization rate of the first scheduling request (SR) resource pool is greater than a threshold, and / or, congestion occurs in the services of the first scheduling request (SR) resource pool.

[0067] To facilitate the understanding of the embodiments of this application, the terms involved in this application are briefly described first. Optionally, the explanations of some terms can also refer to the explanations in the 3rd generation partnership project (3GPP) standard protocol.

[0068] 1. Scheduling request (SR) resource pool The SR resource pool includes physical uplink control channel (PUCCH) resources, and a terminal device can send a scheduling request (SR) based on the SR resource pool to request resources for transmitting uplink data.

[0069] In the embodiments 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 may also be referred to as a normal SR resource pool, and the second SR resource pool may also be referred to as a standby SR resource pool.

[0070] The first SR resource pool and the second SR resource pool can be pre-configured through RRC signaling. Exemplarily: The period of the first SR resource pool and the corresponding PUCCH resources are configured through the RRC parameter normalSR-Config, and the period of the second SR resource pool and the corresponding PUCCH resources are configured through the RRC parameter additionalSR-Config. Among them, the second SR resource pool is in an inactive state by default under the initial configuration.

[0071] It should be noted that in the embodiments of the present application, no specific limitations are imposed 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.

[0072] Exemplarily, the first 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 the steady-state load scenario and meet the 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, which supports dynamic expansion and is used to adapt to the burst traffic scenario to ensure low-latency and 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.

[0073] It should be understood that the technical terms in the present application are only examples and not limitations. For example, as technology evolves, technical terms will also change. Under the condition of the same technical meaning, other technical terms should also apply to the present application.

[0074] In the process of uplink data transmission in the fifth generation mobile communication technology (5G), the user equipment (UE) needs to obtain uplink transmission authorization through the 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.

[0075] SR resource management plays an important role in 5G networks. The existing SR configuration is generally a static resource pool configuration. In high-load scenarios, such as when resource competition intensifies, it is easy to cause delays in the UE's scheduling of uplink resources. In low-load scenarios, fixed resource occupancy results in resource waste.

[0076] 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.

[0077] The following combines the corresponding flowcharts to elaborate on the solution provided by the present application. It can be understood that in the schematic flowcharts provided by the present application, different devices (such as terminal devices and network devices) are mainly used as the execution subjects of the interaction schematic to illustrate the method. However, the present application does not limit the execution subjects of the interaction schematic. For example, the devices (such as terminal devices and network devices) in the schematic flowcharts can also be chips, chip systems, or processors that support the device to implement the method, or logical modules or software that can implement all or part of the functions of the device.

[0078] For unified explanation here, in the interaction process of the embodiments of the present application, the message or signaling interaction involved can adopt the messages or signaling in the standard, or can also be newly introduced messages or signaling. The embodiments of the present application do not make specific limitations on this.

[0079] Figure 2 It is a schematic flowchart of a communication method according to an embodiment of the present application. It can be understood that Figure 2 the terminal device in Figure 1 can be any terminal device in Figure 1 or can also refer to the device in the terminal device (such as a processor, a chip, or a chip system, etc.). The network device can be Figure 2 any access network device in Step S200: The network device sends resource pool configuration information based on radio resource control (RRC) signaling; correspondingly, 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.

[0080] Specifically, the network device can configure the physical uplink control channel (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.

[0081] Among them, the resource configuration of the physical uplink control channel corresponding to the first scheduling request (SR) resource pool is different from that of the physical uplink control channel corresponding to the second scheduling request (SR) resource pool. The second scheduling request (SR) resource pool is in a default inactive state under the initial configuration.

[0082] It should be noted that for the configuration methods of the first scheduling request (SR) resource pool and the second scheduling request (SR) resource pool, please refer to the previous term explanation section, which will not be elaborated here.

[0083] 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 for the terminal device to activate the second scheduling request (SR) resource pool.

[0084] Among them, the network device can detect the operation status of the first scheduling request (SR) resource pool and determine whether to activate the second scheduling request (SR) resource pool 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 activation indication information to the terminal device, and after receiving the activation indication information sent by the network device, the terminal device activates the second scheduling request (SR) resource pool.

[0085] It should be noted that the first scheduling request (SR) resource pool is in a default active state under the initial configuration, that is, the terminal device can use the resources of the first scheduling request (SR) resource pool to perform scheduling requests (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 perform scheduling requests (SR) based on the second scheduling request (SR) resource pool to obtain resources for transmitting uplink data.

[0086] In the above implementation, the network device activates the second scheduling request (SR) resource pool based on the operation status of the first scheduling request (SR) resource pool, enabling the terminal device to use the resources of the first scheduling request (SR) resource pool and the second scheduling request (SR) resource pool for resource scheduling of uplink data transmission, thereby realizing the elastic scaling of scheduling request resources, ensuring the reliability of communication services, and reducing communication overhead.

[0087] In an alternative implementation, the first condition includes: the resource utilization rate of the first scheduling request (SR) resource pool is greater than a threshold, and / or, the service of the first scheduling request (SR) resource pool is congested.

[0088] Among them, the network device can 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.

[0089] It should be noted that the first condition can be pre-configured by the network device. In the embodiments of the present application, no specific limitation is imposed on the first condition, and those skilled in the art can make corresponding settings in combination with specific service requirements.

[0090] In an alternative implementation, the activation indication information is carried in the downlink control information (DCI).

[0091] Among them, the network device can send the activation indication information based on the downlink control information (DCI).

[0092] Optionally, an activation instruction field can be carried in a field of the DCI. Exemplarily, in the DCI 0_1 format, a 1-bit field is configured as the flag bit of the activation instruction, and the activation instruction for the second scheduling request (SR) resource pool is identified based on this flag bit. For example, when the flag bit is 1, it indicates the activation indication information.

[0093] It should be understood that the activation indication information can also be indicated by other fields of the DCI, including the original fields or newly added fields. In the embodiments of the present application, no specific limitation is imposed on the manner in which the activation indication information is carried in the DCI.

[0094] In an alternative implementation, the activation indication information is specifically used for the terminal device to activate the second scheduling request (SR) resource pool within the first timing duration.

[0095] Specifically, the activation indication information is used not only to indicate the activation of the second scheduling request (SR) resource pool, but also 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. That is to say, after receiving the activation indication information, the terminal device triggers the first timer to work, activates the second scheduling request (SR) resource pool within the first timing duration, and when the first timer times out, triggers the disabling of the second scheduling request (SR) resource pool. Thus, the dynamic management of the second scheduling request (SR) resource pool is realized by introducing a timer, and the second scheduling request (SR) resource pool is automatically closed (reverted to the non-activated state) after the timer times out to prevent resource leakage.

[0096] Optionally, a first timing duration field can be carried in a field of the DCI. Exemplarily, 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, and when the first timing duration field is 2, it indicates that the first timing duration is 2 time slots.

[0097] In an alternative implementation, the activation indication information is also used to reset the first timing duration.

[0098] Specifically, within the first timing duration (when the second SR resource pool is in the active state), if the terminal device receives the activation indication information again, the terminal device can reset the first timer, that is, reset the first timing duration. The network device can reset the activation duration of the second scheduling request SR resource pool based on the latest operating state of the first scheduling request SR resource pool, thereby providing a refreshing mechanism for the first timing duration, enabling the embodiments of the present application to adapt to continuous high-load scenarios.

[0099] In an alternative implementation, the resource pool configuration information is further configured to configure the first timing duration, and the first timing duration is associated with the activation duration of the second scheduling request SR resource pool.

[0100] 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: configure the first timing duration simultaneously when configuring the second scheduling request SR resource pool through the RRC parameter additionalSR-Config. Another example: update the first timing duration through an RRC reconfiguration message, which is not limited in the embodiments of the present application. Thereby providing another configuration method and update method for the first timing duration to meet the latency requirements in different service scenarios.

[0101] In an alternative implementation, the communication method provided by the embodiments 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.

[0102] 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 the terminal should preferentially use for uplink resource scheduling through the priority indication information.

[0103] Exemplarily, a 1-bit field SR-Priority in the DCI can be configured as a flag bit for priority indication, and the priority of the scheduling request SR resource pool is determined based on this 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 that of the first scheduling request SR resource pool. At this time, the terminal device preferentially uses the resources of the second scheduling request SR resource pool for uplink resource scheduling. Another example: when the flag bit is 0, it indicates that the priority of the first scheduling request SR resource pool is higher than that of the second scheduling request SR resource pool. At this time, the terminal device preferentially uses the resources of the first scheduling request SR resource pool for uplink resource scheduling. In the embodiments of the present application, the specific configuration method of the priority indication information is not limited.

[0104] It should be understood that the priority indication information can also be indicated by other fields of the DCI, including the original fields or newly added fields. In the embodiments of the present application, the specific manner in which the priority indication information is carried in the DCI is not specifically limited.

[0105] In the above implementation, the network device can, based on the real-time network load situation, for example, in a scenario with ultra-reliable low latency communications (URLLC) burst traffic, configure the priority of the second scheduling request SR resource pool to be higher than that of the first scheduling request SR resource pool. Thus, the terminal device can use the resources of the second scheduling request SR resource pool for uplink resource scheduling, ensuring the timeliness and reliability of the uplink scheduling. Thus, the priority of the scheduling request resource pool can be dynamically adjusted through the priority indication information, flexibly adapting to the uplink scheduling requirements in different service scenarios, and ensuring that critical services are scheduled first.

[0106] Next, in combination with Figure 3 the following schematic flowchart of another communication method shows the communication method provided by the embodiments of the present application.

[0107] 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 active state by default, and the second scheduling request SR resource pool is in the inactive state by default.

[0108] 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 for uplink resource scheduling.

[0109] Next, 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 activation indication information to activate the second SR resource pool and synchronously triggers the first timer.

[0110] Finally, the terminal device detects whether the first timer times out. When the first timer times out, the second SR resource pool is disabled, and it will fall back to only using the first SR resource pool for uplink resource scheduling; when the first timer does not time out, the second SR resource pool is kept in an active state.

[0111] It can be determined through the above process that the embodiments of the present application provide a solution for dynamically activating the SR resource pool. The network device can decide whether to enable the standby SR resource according to the real-time network load, realizing the elastic scaling of resources. And a timer is introduced to manage the activation duration of the standby SR resource pool, which will be automatically closed after timing out to prevent resource leakage. The timing duration of the timer can be configured and adjusted by the network device, supporting flexible adaptation to the latency requirements of different scenarios, and the timer can be refreshed to adapt to the scenario of continuous high load.
