1. A user equipment (UE), the UE comprising:
processor circuitry configured to:
perform a first channel load measurement for first signals received from a new radio (NR) serving cell at a first frequency having a first priority and a second channel load measurement for second signals received from an NR neighbor cell at a second frequency having a second priority, wherein at least one of the first frequency and the second frequency is in an unlicensed spectrum, and wherein each of the first signals and second signals include reference signals and data signals;
associate a report with the first channel load measurement and the second channel load measurement;
select the NR serving cell or the NR neighbor cell for the UE based at least on the first and second channel load measurements and the first and second priorities; and
radio front end circuitry coupled to the processor circuitry and configured to transmit the report to an access node (AN) of the NR serving cell.
