Abstract: According to the present invention, a common control signal via a group common control channel (GCCC) for a new radio access technology (NR) is defined. A user equipment (UE) receives the common control signal from a network via GCCC. The common control signal is for all UEs or a group of UEs in a cell. The UE handles the priority of the common control signal compared to other signals. For example, the priority of the common control signal may be higher than a semi-static UE-specifically configured configuration, and may be lower than a cell—commonly or group-commonly configured configuration.
