Abstract

A communication device includes: a communication unit configured to perform wireless communication; and a control unit configured to allocate respective resources for communication with a plurality of terminal devices in which at least any of bandwidths or central frequencies of channels to be used is different. 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.

Dependent claims

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.

A non-transitory computer-readable storage medium encoded with instructions, which, when executed by a communication device, cause the communication device to execute a process, the process 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;
performing either one of a first wireless communication using the first frequency band, or a second wireless communication using the second frequency band;
and
receiving a packet for an initial access by the first wireless communication being performed using the first frequency band;
and
transmitting 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.
