Title:
WIRELESS BASE STATION AND WIRELESS TERMINAL
Document Type and Number:
WIPO Patent Application WO/2021/176836
Kind Code:
A1
Abstract:
The present invention accurately estimates interference to another terminal for cooperative transmission by a plurality of wireless base stations. This wireless base station comprises a wireless control unit and a communication unit. At the time of cooperative transmission with a cooperative wireless base station, the wireless control unit generates a reference signal for estimating interference given to a wireless terminal connected to another wireless base station, and determines a cooperative transmission-related setting in accordance with the interference estimation result based on the reference signal. The communication unit transmits the reference signal to the another wireless base station or a wireless terminal, and notifies the cooperative wireless base station of the cooperative transmission-related setting.
