Method and apparatus for requesting scheduling sidelink resource, and storage medium

1. A method for requesting scheduling sidelink resources, applicable to a terminal device, comprising:

sending a sidelink terminal message to a network device, wherein the sidelink terminal message comprises a request initiated by the terminal device for performing sidelink resource scheduling by the terminal device;

receiving a response message corresponding to the sidelink terminal message sent by the network device;

in response to the response message being a first response message indicating that the request from the terminal device is approved, obtaining assigned sidelink resource configuration information from the first response message; and

performing sidelink resource scheduling for respective terminal devices within a user group including the terminal device based on the assigned sidelink resource configuration information;

the method of claim further comprising:

in response to the response message being a second response message indicating that the request of the terminal device is rejected, obtaining timer configuration information from the second response message;

starting a timer based on the timer configuration information and suspending sending the sidelink terminal message to the network device before the timer expires.

2. The method of claim 1 , wherein the sidelink terminal message further comprises a group identifier of the user group, an identifier of each terminal device within the user group, and the number of scheduled terminal devices within the user group.

3. The method of claim 1 , wherein the performing the sidelink resource scheduling for respective terminal devices within the user group including the terminal device based on the assigned sidelink resource configuration information comprises:

obtaining a time range and a frequency range corresponding to assigned sidelink resources from the assigned sidelink resource configuration information; and

performing the sidelink resource scheduling for respective terminal devices within the user group based on the time range and the frequency range.

4. The method of claim 1 , wherein, each of the first response message and the second response message is selected from the group consisting of

RRCConnectionReconfiguration; and

RRCReconfiguration.

5. The method of claim 1 , wherein the sending the sidelink terminal message to the network device comprises:

sending the sidelink terminal message to the network device based on a broadcast message received from the network device.

6. The method of claim 1 , further comprising:

determining terminal devices for which sidelink resources need to be scheduled within the user group.

7. The method of claim 6 , wherein the determining the terminal devices for which the sidelink resources need to be scheduled within the user group comprises:

sending querying information to another terminal device within the user group; and

determining that the sidelink resource needs to be scheduled for the another terminal device when receiving return information indicating that the sidelink resource needs to be scheduled for the another terminal device.

8. The method of claim 6 , wherein the determining the terminal devices for which the sidelink resources need to be scheduled within the user group comprises:

determining that the sidelink resource needs to be scheduled for another terminal device when receiving a request for sidelink resources from the another terminal device.

9. A device for requesting scheduling sidelink resources, comprising:

a processor; and

a memory for storing instructions executable by the processor;

wherein the processor is configured to perform the method for requesting scheduling of side-link resources, comprising:

sending a sidelink terminal message to a network device, wherein the sidelink terminal message comprises a request initiated by the terminal device for performing sidelink resource scheduling by the terminal device;

receiving a response message corresponding to the sidelink terminal message sent by the network device;

in response to the response message being a first response message indicating that the request from the terminal device is approved, obtaining assigned sidelink resource configuration information from the first response message; and

performing sidelink resource scheduling for respective terminal devices within a user group including the terminal device based on the assigned sidelink resource configuration information;

wherein the processor is configured to further perform:

in response to the response message being a second response message indicating that the request of the terminal device is rejected, obtaining timer configuration information from the second response message;

starting a timer based on the timer configuration information and suspending sending the sidelink terminal message to the network device before the timer expires.

10. The device of claim 9 , wherein the sidelink terminal message further comprises a group identifier of the user group, an identifier of each terminal device within the user group, and the number of scheduled terminal devices within the user group.

11. The device of claim 9 , wherein the performing the sidelink resource scheduling for respective terminal devices within the user group including the terminal device based on the assigned sidelink resource configuration information comprises:

obtaining a time range and a frequency range corresponding to assigned sidelink resources from the assigned sidelink resource configuration information; and

performing the sidelink resource scheduling for respective terminal devices within the user group based on the time range and the frequency range.

12. The device of claim 9 , wherein, each of the first response message and the second response message is selected from the group consisting of

RRCConnectionReconfiguration; and

RRCReconfiguration.

13. A non-transitory computer readable storage medium, wherein when instructions in the storage medium are executed by a processor, the processor is caused to perform the method for requesting scheduling of side-link resources, comprising:

sending a sidelink terminal message to a network device, wherein the sidelink terminal message comprises a request initiated by the terminal device for performing sidelink resource scheduling by the terminal device;

receiving a response message corresponding to the sidelink terminal message sent by the network device;

in response to the response message being a first response message indicating that the request from the terminal device is approved, obtaining assigned sidelink resource configuration information from the first response message; and

performing sidelink resource scheduling for respective terminal devices within a user group including the terminal device based on the assigned sidelink resource configuration information;

wherein the processor is further caused to perform:

in response to the response message being a second response message indicating that the request of the terminal device is rejected, obtaining timer configuration information from the second response message;

starting a timer based on the timer configuration information and suspending sending the sidelink terminal message to the network device before the timer expires.

14. The non-transitory computer readable storage medium of claim 13 , wherein the sidelink terminal message further comprises a group identifier of the user group, an identifier of each terminal device within the user group, and the number of scheduled terminal devices within the user group.

15. The non-transitory computer readable storage medium of claim 13 , wherein the performing the sidelink resource scheduling for respective terminal devices within the user group including the terminal device based on the assigned sidelink resource configuration information comprises:

obtaining a time range and a frequency range corresponding to assigned sidelink resources from the assigned sidelink resource configuration information; and

performing the sidelink resource scheduling for respective terminal devices within the user group based on the time range and the frequency range.

16. The non-transitory computer readable storage medium of claim 13 , wherein, each of the first response message and the second response message is selected from the group consisting of
