UE CAPABILITY SIGNALING TO SUPPORT ENHANCEMENTS OF A RANDOM ACCESS OPERATION FOR 5G NEW RADIO (NR) IN UNLICENSED SPECTRUM (NR-U)

摘要

A method for UE capability signaling to support enhancements of a random access operation for NR-U is proposed. A UE transfers UE capability information to a mobile communication network, and the UE capability information includes information indicating the UE's capability on random access operation in unlicensed spectrum. The UE receives configuration of an unlicensed cell from the mobile communication network. The UE performs a random access operation on the unlicensed cell according to the configuration.
