Abstract
A user equipment (UE) and a sidelink resource exclusion method are provided. The sidelink resource exclusion method includes identifying a first sidelink resource selected by the UE or reserved by a peer UE in a first slot from a candidate resource set in a resource selection window and in a first sidelink resource pool and excluding the first sidelink resource and/or sidelink subchannels in the first slot from the candidate resource set. This can solve issues in the prior art, increase a number of available resources that can be selected from the remaining candidate resource set, reduce interference to other transmissions in the same sidelink resource pool, reduce probability of transmission (Tx) collisions with other UEs, provide a good communication performance, and/or provide high reliability.
Claims18
A user equipment (UE), comprising:
- a memory;
- a transceiver;
- and
- a processor coupled to the memory and the transceiver;
- wherein the processor is configured to identify a first sidelink resource selected by the LE or reserved by a peer LE in a first slot from a candidate resource set in a resource selection window and in a first sidelink resource pool;
- wherein the processor is configured to exclude the first sidelink resource and/or sidelink subchannels in the first slot from the candidate resource set,
- wherein the processor is further configured to perform monitoring on configured slots of the first sidelink resource pool by decoding a physical sidelink control channel (PSCCH) and measuring a reference signal received power (RSRP) within a sensing window;
- and
- wherein the processor is further configured to exclude sidelink subchannels from the candidate resource set according to:
- an indicated resource reservation period in a Sidelink Control Information (SCI) during the sensing window;
- and
- a configured subset of allowed reservation periodicities for the first sidelink resource pool in non-monitored slots during the sensing window, wherein a quantity of reservation periodicities in the configured subset is less than a quantity of the allowed reservation periodicities for the first sidelink resource pool.
A sidelink resource exclusion method by a user equipment (UE), comprising:
- identifying a first sidelink resource selected by the JE or reserved by a peer UJE in a first slot from a candidate resource set in a resource selection window and in a first sidelink resource pool;
- excluding the first sidelink resource and/or sidelink subchannels in the first slot from the candidate resource set;
- performing monitoring on configured slots of the first sidelink resource pool by decoding a physical sidelink control channel (PSCCH) and measuring a reference signal received power (RSRP) within a sensing window;
- and
- excluding sidelink subchannels from the candidate resource set according to:
- an indicated resource reservation period in a Sidelink Control Information (SCI) during the sensing window;
- and
- a configured subset of allowed reservation periodicities for the first sidelink resource pool in non-monitored slots during the sensing window, wherein a quantity of reservation periodicities in the configured subset is less than a quantity of the allowed reservation periodicities for the first sidelink resource pool.
