Abstract

Claims (38)

1 . An electronic device for a first terminal device, wherein the electronic device comprises a processing circuit, and the processing circuit is configured to:

search for time-frequency resources based on at least two allocation modes to obtain a candidate resource set;

select a time-frequency resource from the candidate resource set;

notify a second terminal device of the selected time-frequency resource to be used for sidelink communication with the second terminal device; and

send resource selection information to a base station, wherein the resource selection information indicates whether a specified resource is selected,

wherein the search for the time-frequency resources based on at least two allocation modes comprises:

for a first allocation mode, sending a resource scheduling request message to the base station, and receiving a resource grant message from the base station; and

for a third allocation mode, sending a resource scheduling request message to a cluster scheduling device, and receiving a resource grant message from the cluster scheduling device,

wherein the candidate resource set comprises time-frequency resources corresponding to the first and third allocation modes.

2 . The electronic device of claim 1 , wherein the searching for time-frequency resources based on at least two allocation modes further comprises:

for a second allocation mode, perceiving and searching for time-frequency resources,

wherein the candidate resource set further comprises time-frequency resources corresponding to the second allocation mode.

3 . The electronic device of claim 2 , wherein the perceiving and searching for time-frequency resources for the second allocation mode comprises:

perceiving resources in a resource window, and selecting a desired resource based on a perception result.

4 . The electronic device of claim 2 , wherein the selecting the time-frequency resource comprises:

selecting the time-frequency resource based on a QoS requirement of sidelink communication and attributes of time-frequency resources in the candidate resource set, wherein a time-frequency resource corresponding to one or more allocation modes is selected.

5 . The electronic device of claim 4 , wherein the resource selection information indicates, to the base station, whether a time-frequency resource corresponding to the first allocation mode is selected.

6 . The electronic device of claim 5 , wherein the resource selection information further indicates, to the base station, a time-frequency resource selected from time-frequency resources corresponding to the second or third allocation mode.

7 . The electronic device of claim 1 , wherein the first terminal device is used as the cluster scheduling device, and the processing circuit is configured to:

send a resource pool scheduling request message to the base station, and receive a resource pool grant message from the base station; and

in response to a resource scheduling request message from a specified terminal device, select a time-frequency resource from the resource pool, so as to provide grant for the specified terminal device.

8 . The electronic device of claim 1 , the processing circuit is further configured to: receive, from the base station, parameter configurations of the at least two allocation modes by using radio resource control RRC signaling.

9 . The electronic device of claim 1 , where the processing circuit is further configured to: receive, from the second terminal device, information on a time-frequency resource selected by the second terminal device, where the information on the time-frequency resource is used for receiving sidelink communication from the second terminal device.

10 . The electronic device of claim 1 , wherein the processing circuit is further configured to:

transmit specific time-frequency resource information or index by using sidelink control information to notify the second terminal device of the selected time-frequency resource.

11 . A method for wireless communication, comprising:

by a first terminal device:

searching for time-frequency resources based on at least two allocation modes to obtain a candidate resource set;

selecting a time-frequency resource from the candidate resource set;

notifying a second terminal device of the selected time-frequency resource to be used for sidelink communication with the second terminal device; and

sending resource selection information to a base station, wherein the resource selection information indicates whether a specified resource is selected,

wherein the searching for the time-frequency resources based on at least two allocation modes comprises:

for a first allocation mode, sending a resource scheduling request message to the base station, and receiving a resource grant message from the base station; and

for a third allocation mode, sending a resource scheduling request message to a cluster scheduling device, and receiving a resource grant message from the cluster scheduling device,

wherein the candidate resource set comprises time-frequency resources corresponding to the first and third allocation modes.

12 . The method of claim 11 , wherein the searching for time-frequency resources based on at least two allocation modes further comprises:

for a second allocation mode, perceiving and searching for time-frequency resources,

wherein the candidate resource set further comprises time-frequency resources corresponding to the second allocation mode.
