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. ## Claims ### Claim 1 A method performed by a user equipment (UE) in a wireless communication system, the method comprising: receiving a group common control signal from a network via a group common control channel (GCCC), wherein the group common control signal is scheduled to a group of UEs with a radio network temporary identity (RNTI) specific to the group common control channel; receiving a signal other than then group common control signal from the network; and handling a priority of the group common control signal compared to a priority of the signal. ### Claim 2 (depends on 1) The method of claim 1, wherein the priority of the group common control signal is higher than the priority of the signal when the signal is a semi-static UE-specifically configured configuration. ### Claim 3 (depends on 1) The method of claim 1, wherein the priority of the group common control signal is lower than the priority of the signal when the signal is a semi-static cell-commonly configured configuration. ### Claim 4 (depends on 1) The method of claim 1, wherein the priority of the group common control signal is lower than the priority of the signal when the signal is a dynamic UE-specifically indicated configuration via scheduling. ### Claim at position 5 5-9. (canceled) ### Claim 10 (depends on 1) The method of claim 1, wherein the group common control signal is received in a subset of candidates or in a first orthogonal frequency division multiplexing (OFDM) symbol of a control region or in a frequency region among control resource sets. ### Claim 11 (depends on 1) The method of claim 1, wherein the group common control signal indicates at least one of whether a type of a current subframe is UL-centric or DL-centric, whether a type of a next subframe type is UL-centric or DL-centric, whether the current subframe is scheduled with single-level downlink control information (DCI) or multi-level DCI, whether the next subframe is scheduled with single-level DCI or multi-level DCI, a size of common or group-specific shared control resource set, or an indication of actual DL resource, UL resource and/or reserved resource. ### Claim 12 (depends on 1) The method of claim 1, wherein the group common control signal is received via either self-carrier scheduling or a cross-carrier scheduling. ### Claim 13 (depends on 1) The method of claim 1, wherein an exact length of a long physical uplink control channel (PUCCH) format is indicated from the network. ### Claim 14 (canceled) ### Claim 15 A user equipment (UE) in a wireless communication system, the UE comprising: a memory; a transceiver; and a processor, operably coupled to the memory and the transceiver, that: controls the transceiver to receive a group common control signal from a network via a group common control channel (GCCC), wherein the group common control signal is scheduled to a group of UEs with a radio network temporary identity (RNTI) specific to the group common control channel, controls the transceiver to receive a signal other than then group common control signal from the network, and handles a priority of the group common control signal compared to a priority of the signal. ### Claim 16 (depends on 2) The method of claim 2, wherein the semi-static UE-specifically configured configuration is a configuration of a sounding reference signal (SRS) transmission. ### Claim 17 (depends on 2) The method of claim 2, wherein the semi-static UE-specifically configured configuration is a configuration of a channel state information reference signal (CSI-RS) transmission. ### Claim 18 (depends on 3) The method of claim 3, wherein the semi-static cell-commonly configured configuration is a configuration of at least one of a system information block (SIB) or a physical broadcast channel (PBCH). ### Claim 19 (depends on 1) The method of claim 1, wherein the group common control signal indicates a first resource type, and wherein the signal indicates a second resource type different from the first resource type. ### Claim 20 (depends on 19) The method of claim 19, wherein the group common control signal overrides the signal when the second resource type indicates a flexible resource. ### Claim 21 (depends on 19) The method of claim 19, wherein the group common control signal does not override the signal when the second resource type indicates a fixed downlink (DL) resource or a fixed uplink (UL) resource.
