The control unit allocates a first control channel to be commonly transmitted to the plurality of terminal devices to a first region overlapping between the respective channels of the plurality of terminal devices in a region in which the resources are allocated. The control unit allocates a second control channel to be individually transmitted to each of the plurality of terminal devices to a second region different from the first region. ## Claims ### Claim 1 A communication device comprising: circuitry configured to set a first frequency band and a second frequency band, the first frequency band being defined by a combination of a first bandwidth and a first subcarrier spacing, the second frequency band being defined by a combination of a second bandwidth and a second subcarrier spacing, at least one of the second bandwidth or the second subcarrier spacing being different from the first bandwidth or the second subcarrier spacing, respectively, perform either one of a first wireless communication using the first frequency band, or a second wireless communication using the second frequency band, receive a packet for an initial access by the first wireless communication being performed using the first frequency band, and transmit an instruction of Physical Downlink Control Channel (PDCCH) to switch from the first wireless communication using the first frequency band to the second wireless communication using the second frequency band. ### Claim 2 (depends on 1) The communication device according to claim 1, wherein the circuitry is configured to transmit the instruction of PDCCH to switch from the first wireless communication using the first frequency band to the second wireless communication using the second frequency band, based on a radio resource control (RRC) signaling. ### Claim 3 (depends on 1) The communication device according to claim 1, wherein the either one of the first wireless communication or the second wireless communication is performed at a time. ### Claim 4 (depends on 1) The communication device according to claim 1, wherein the circuitry is configured to transmit the instruction of PDCCH to switch from the first wireless communication using the first frequency band to the second wireless communication using the second frequency band, based on information of a random access response. ### Claim 5 (depends on 4) The communication device according to claim 4, wherein the circuitry is configured to transmit the instruction of PDCCH to switch from the first wireless communication using the first frequency band to the second wireless communication using the second frequency band, based on contention resolution information for notifying of completion of the random access. ### Claim 6 A method for communication device comprising: setting a first frequency band and a second frequency band, the first frequency band being defined by a combination of a first bandwidth and a first subcarrier spacing, the second frequency band being defined by a combination of a second bandwidth and a second subcarrier spacing, at least one of the second bandwidth or the second subcarrier spacing being different from the first bandwidth or the second subcarrier spacing, respectively;
