Resource allocation mode 1 operation in FR2 sidelink
A UE receives, from a network entity, an allocation of resources for a sidelink transmission, the allocation of resources including an indication of a destination identifier (ID). The UE transmits the sidelink transmission to a second UE based on the allocation of resources for the sidelink transmission and the destination ID associated with the second UE. A UE receives, from a first UE, a request to form a connection for sidelink communication. The UE measures at least one colliding sidelink transmission from at least one additional UE interfering with a sidelink transmission from the first UE and transmits, to a network entity, a sidelink collision report indicating the measured at least one colliding sidelink transmission from the at least one additional UE. The UE communicates, with the first UE, via the sidelink communication based on an allocation of resources for the sidelink transmission after the sidelink collision report.
