Abstract
A radio base station (100A) transmits channel allocation information to a radio communication terminal by using a downward frame containing a map region which is broadcast by a non-directivity beam and a particular region transmitted toward a predetermined direction by a directivity beam. The radio base station (100A) includes: a traffic state acquisition unit (105) which acquires the traffic state handled by a mobile communication system (1); and a frame control unit (107) which changes the size of the particular region in the downward frame according to the traffic state obtained by the traffic state acquisition unit (105).
Claims9
A radio base station configured to transmit, to a radio communication terminal, channel allocation information indicating allocation of a radio communication channel by using a downlink frame containing a map region broadcasted by a non-directional beam and a specific region transmitted in a predetermined direction by a directional beam, the radio base station comprising:
- a traffic state acquisition unit configured to acquire a traffic state between the radio communication terminal and the radio base station;
- and
- a frame controller configured to change a size of the specific region in the downlink frame on the basis of the traffic state acquired by the traffic state acquisition unit.
A radio communication method tor transmitting, to a radio communication terminal, channel allocation information which indicates allocation of a radio communication channel by using a downlink frame containing a map region broadcasted by a non-directional beam, and a specific region transmitted in a predetermined direction by a directional beam, the method comprising:
- acquiring a traffic state between the radio communication terminal and the radio base station;
- and
- changing a size of the specific region in the downlink frame on the basis of the traffic state acquired.
