COMMUNICATION CONTROL METHOD, WIRELESS COMMUNICATION SYSTEM, WIRELESS BASE STATION AND USER TERMINAL

WIPO Patent Application WO/2013/183542

A1

This wireless communication method suppresses degradation of communication quality even different DL/UL configurations are applied at neighboring transmission/reception points (wireless base stations). In a wireless communication system in which wireless base stations communicate by time-division duplexing with user terminals and each wireless base station individually varies the DL/UL configuration, this wireless communication method is characterized by involving: a step for generating a control signal indicating the number and position of the those subframes configuring the wireless frames in each wireless base station that are allocated for use in DL and/or UL transmission; and a step in which the aforementioned control signal is sent to the user terminal by a downlink control channel of the specific subframes configuring said wireless frame.
