A user equipment (UE) is described. The UE includes receiving circuitry configured to receive first downlink control information (DCI) used for indicating a deactivation of a configured grant corresponding to a configured grant configuration with a first index. The UE also includes transmitting circuitry configured to transmit, based on a reception of the first DCI, a configured grant confirmation medium access control (MAC) control element (CE). The configured grant confirmation MAC CE includes a value indicating a deactivation status of the configured grant configuration with the first index.
