1. A resource selection method in sidelink communication by a first user equipment (UE), comprising:
receiving sidelink data traffic and transmission related information from a second UE; and
reporting, to the second UE, a set of one or more preferred resources or slot timings of a sidelink resource pool,
wherein the preferred resources or slot timings of the sidelink resource pool enables the second UE to select one or more resources for sidelink transmission based on resource sensing and exclusion, by performing sensing operation based on a decoding physical sidelink control channel/sidelink control information (PSCCH/SCI) and a measuring reference signal received power (RSRP) of a received PSCCH/SCI in slots belong to the sidelink resource pool; initializing a set of candidate resources by taking a reported set of preferred resources from the first UE or by initializing to a set of all possible resources within a selection window in the sidelink resource pool; and performing exclusion of resources from the set of candidate resources based on a sensing outcome, and
wherein if a remaining candidate set after the resource exclusion is not based on the reported set of preferred resources from the first UE, a final selection of sidelink resource is based on common resources between the remaining candidate set and the reported resource set.
