The present invention is designed to reduce the deterioration of communication quality even when different DL/UL configurations are applied between neighboring transmitting/receiving points (radio base stations). A radio communication method in a radio communication system, in which a plurality of radio base stations that communicate with a user terminal by means of time division duplexing each change the DL/UL configuration independently, includes the steps in which each radio base station generates a control signal that designates the number and positions of subframes to be allocated for DL and/or UL transmission among subframes constituting a radio frame, and transmits the control signal to the user terminal on a downlink control channel of a specific subframe constituting the radio frame.
A communication control method in a radio communication system in which a plurality of radio base stations that communicate with a user terminal by means of time division duplexing each change a DL/UL configuration independently, the communication control method comprising the steps in which each radio base station:
A radio communication system in which a plurality of radio base stations that communicate with a user terminal by means of time division duplexing each change a DL/UL configuration independently, wherein each radio base station comprises:
A radio base station in a radio communication system in which a plurality of radio base stations that communicate with a user terminal by means of time division duplexing each change a DL/UL configuration independently, the radio base station comprising:
A user terminal in a radio communication system in which a plurality of radio base stations that communicate with a user terminal by means of time division duplexing each change a DL/UL configuration independently, the user terminal comprising:
