Abstract: A terminal includes: a reception unit configured to receive a block including a synchronization signal and a broadcast channel, a control channel carrying control information, and a shared channel carrying system information by applying single beamforming; and a control unit configured to perform an initial access, based on the system information. The block and one or both of the control channel and the shared channel are frequency-multiplexed, and the control channel and the shared channel are time-multiplexed.
