Abstract
Methods and apparatuses for adaptive low-power sensing operations for sidelink (SL) communications in a wireless communication system. A method of operating a user equipment (UE) includes operating with partial sensing; operating in a resource pool configured for the partial sensing; and triggering for a SL resource selection in a slot n. The method further includes selecting Y candidate slots for the SL resource selection and performing, in a sensing window, a contiguous partial sensing (CPS). A first of the selected Y candidate slots is a slot t′y0SL. The sensing window is in contiguous slots within the resource pool relative to the slot t′y0SL.
Claims18
A user equipment (UE), comprising:
- a transceiver;
- and
- a processor operably coupled to the transceiver, the processor configured to:
- operate with partial sensing;
- operate in a resource pool configured for the partial sensing;
- trigger a sidelink (SL) resource selection in a slot n;
- select Y candidate slots for the SL resource selection, wherein a first of the selected Y candidate slots is a slot t′y0SL;
- and
- perform, in a sensing window, a contiguous partial sensing (CPS), wherein:
- the sensing window is in contiguous slots within the resource pool relative to the slot t′y0SL,
- an end of the sensing window is Tproc,0SL+Tproc,1SL before the slot t′y0SL,
- Tproc,0SL is a sensing processing latency time, and
- Tproc,1SL is a resource selection processing time.
A method of operating a user equipment (UE), the method comprising:
- operating with partial sensing;
- operating in a resource pool configured for the partial sensing;
- triggering for a sidelink (SL) resource selection in a slot n;
- selecting Y candidate slots for the SL resource selection, wherein a first of the selected Y candidate slots is a slot t′y0SL;
- and
- performing, in a sensing window, a contiguous partial sensing (CPS), wherein:
- the sensing window is in contiguous slots within the resource pool relative to the slot t′y0SL,
- an end of the sensing window is Tproc,0SL+Tproc,1SL before the slot t′y0SL,
- Tproc,0SL is a sensing processing latency time, and
- Tproc,1SL is a resource selection processing time.
