Abstract:
1. A radio base station of an adaptive array radio scheme applying an antenna weight to a plurality of antennas, comprising: a transmission unit that transmits reference signal transmission frequency band control information, to a serving radio terminal, for controlling a reference signal transmission frequency band available in a transmission of a reference signal from the serving radio terminal, the reference signal being referenced in a calculation of the antenna weight, wherein in case that one serving radio terminal included in a plurality of serving radio terminals transmits a reference signal of a first reference signal transmission frequency band at a predetermined timing, the transmission unit transmits transmission stop request information indicating a request to stop the transmission of the reference signal of the first reference signal transmission frequency band at the predetermined timing, to another serving radio terminal in response to the radio base station receiving a reference signal from a non-serving radio terminal communicating with another radio base station.
