Abstract:
1. A radio base station that transmits channel allocation information indicating allocation of a radio communication channel, to a radio communication terminal by using a downlink frame including a broadcast control channel broadcasted by using an omnidirectional beam and a dedicated control channel transmitted in a predetermined direction by using a directional beam, the radio base station comprising: a propagation path characteristic acquisition unit configured to acquire a propagation path characteristic between the radio communication terminal and the radio base station; a notification unit configured to notify the radio communication terminal that the channel allocation information is to be transmitted by using the dedicated control channel, if the propagation path characteristic acquired by the propagation path characteristic acquisition unit satisfies a predetermined condition; and a channel allocation information transmitter configured to transmit the channel allocation information by using the dedicated control channel in the downlink frame, after the notification unit notifies the radio communication terminal that the channel allocation information is to be transmitted by using the dedicated control channel, wherein the channel allocation information transmitter transmits the channel allocation information by using the broadcast control channel and the dedicated control channel if the propagation path characteristic acquired by the propagation path characteristic acquisition unit satisfies the predetermined condition.
