Abstract
A user equipment (UE) and a resource selection method in sidelink communication are provided. The resource selection method by a first UE includes requesting a second UE to provide a set of resources by transmitting, to the second UE, a UE assistance information (UEAI) or a scheduling request/buffer status report (SR/BSR) information, receiving the set of resources from the second UE, and selecting or avoiding selecting one or more resources from the set resources for sidelink transmission. This can solve issues in the prior art, avoid transmission collisions with one or more hidden UEs, avoid a half-duplex issue for UEs belong to a same group, save a transmitter UE processing power, provide a good communication performance, and/or provide high reliability.
Claims14
A resource selection method in sidelink communication by a first user equipment (UE), comprising:
- triggering a second UE to provide a set of resources by sending, to the second UE, a UE assistance information;
- receiving the set of resources from the second UE;
- and
- avoiding selecting one or more resources from the set of resources for sidelink transmission,
- wherein the resource selection method further comprises:
- triggering the second UE to perform monitoring on a sidelink resource pool and exclude resources within a resource selection window,
- wherein the set of resources comprises a remaining candidate resource set from the second UE,
- wherein the UE assistance information comprises a resource selection window start and finish time.
A first user equipment (UE), comprising:
- a memory;
- a transceiver;
- and
- a processor coupled to the memory and the transceiver;
- wherein the processor is configured to perform:
- triggering a second UE to provide a set of resources by sending, to the second UE, a UE assistance information;
- receiving the set of resources from the second UE;
- and
- avoiding selecting one or more resources from the set of resources for sidelink transmission,
- wherein the processor is further configured to trigger the second UE to perform monitoring on a sidelink resource pool and exclude resources within a resource selection window,
- wherein the set of resources comprises a remaining candidate resource set from the second UE,
- wherein the UE assistance information comprises a resource selection window start and finish time.
A non-transitory machine-readable storage medium, comprising instructions stored on the non-transitory machine-readable storage medium, wherein when executed by a computer, the instructions cause the computer to perform:
- triggering a second UE to provide a set of resources by sending, to the second UE, a UE assistance information;
- receiving the set of resources from the second UE;
- and
- avoiding selecting one or more resources from the set of resources for sidelink transmission,
- wherein the computer is further configured to trigger the second UE to perform monitoring on a sidelink resource pool and exclude resources within a resource selection window,
- wherein the set of resources comprises a remaining candidate resource set from the second UE,
- wherein the UE assistance information comprises a resource selection window start and finish time.
