1. A method of a first device to perform device-to-device or sidelink transmission and reception, comprising:
the first device performs sensing on a resource pool comprising data resources;
the first device selects or derives at least a first data resource from the resource pool based on sensing result on the resource pool, wherein the sensing comprises the first device receiving a transmission and excluding candidate resources associated with the transmission;
the first device transmits a first control information on a first control resource, wherein the first control information allocates or indicates the first data resource;
the first device performs a first data transmission on the first data resource to at least a second device;
the first device determines or derives a first set of feedback resources based on the first control resource and/or the first data resource without sensing on a candidate set of feedback resources associated with the data resources, and wherein the candidate set of feedback resources comprises the first set of feedback resources;
the first device determines or derives a first feedback resource of the first set of feedback resources based on an identity of the second device within a sidelink group; and
the first device receives a first feedback transmission on the first feedback resource from at least the second device, wherein the first feedback transmission includes Hybrid Automatic Repeat Request (HARQ) feedback information associated with the first data transmission.
