7. A base station (BS), comprising:
a transceiver configured to receive, on a Uu interface, a message including first sidelink (SL) inter-user equipment (UE) coordination information from a first UE, and
a processor operably coupled to the transceiver, the processor configured to:
determine SL resources for a SL transmission based on the first SL inter-UE coordination information,
determine a second UE as a recipient for the first SL inter-UE coordination information, and
generate second SL inter-UE coordination information from aggregation of the first SL inter-UE coordination information and other SL inter-UE coordination information,
wherein the transceiver is further configured to transmit the second SL inter-UE coordination information to the second UE via a groupcast message,
wherein the second SL inter-UE coordination information includes information indicating resources that are not preferred, and
wherein the SL resources are determined by excluding the resources that are not preferred.
