transmitting, by the first terminal device via the first resource, first data to the second terminal device, wherein the first data is used to trigger the second terminal device to start a first timer.
7 . The method according to claim 1 , wherein said determining, by the first terminal device, the first candidate resource set comprises:
determining, by the first terminal device, the first candidate resource set within a resource selection window based on a sensing result.
8 . The method according to claim 1 , wherein the first DRX configuration information comprises at least one of:
a first DRX parameter, drx-onDurationTimer;
a second DRX parameter, drx-InactivityTimer;
a third DRX parameter, drx-LongCycle and drx-StartOffset; and
a fourth DRX parameter, drx-SlotOffset.
9 . A non-transitory computer-readable storage medium, having a computer program stored thereon, wherein the computer program causes a computer to perform the method according to claim 1 .
10 . A terminal device, comprising:
a memory having a computer program stored thereon; and
a processor configured to invoke and execute the computer program stored in the memory to:

select a first resource having a time domain position located within the first time range;
and further to:
determine a first candidate resource set, wherein the first resource belongs to the first candidate resource set;
select a second resource, wherein the second resource belongs to the first candidate resource set, and a time domain position of the second resource is located within the first time range;
wherein the first resource and the second resource are used to transmit a same sidelink data block.
11 . The terminal device according to claim 10 , wherein the first DRX configuration information is DRX configuration information of the second terminal device; and the processor is further configured to invoke and execute the computer program stored in the memory to:
receive the first DRX configuration information transmitted by the second terminal device.
