Abstract: A communication device includes a transmission unit that, when priority of uplink data is predetermined priority, preferentially over an operation concerning mobility, transmits a buffer status report linked with the uplink data to a base station and a reception unit that receives, from the base station, an uplink scheduling grant corresponding to the buffer status report.

Abstract: A communication device includes a communication unit and a control unit. The communication unit performs wireless communication using at least one of a plurality of beams. The control unit acquires service communication quality corresponding to quality requested on a service. The control unit obtains, by estimation, an estimated communication quality achievable by the communication unit, based on a radio wave propagation environment. Even in a case where a beam quality of a non-currently working beam, a beam which is not being used for wireless communication, is higher than the beam quality of a currently working beam, which is being used for wireless communication, the control unit maintains the communication by the currently working beam in a case where the estimated communication quality is the service communication quality or more. Where the estimated communication quality is below the service communication quality, the control unit determines switching of the beam.
