BASE STATION AND COORDINATED TRANSMISSION MODE SELECTION METHOD

摘要

In order to select an optimum mode according to a network situation in coordinated transmission to thereby improve system performance, a coordination mode selection unit (112) selects a JT mode when an X2 transfer time included in feedback information received from another base station is less than a second threshold value, or a Blanking mode when the X2 transfer time is the second threshold value or more. An inter-base station coordination control unit (113) performs inter-base station coordination control with the other base station in order to execute a coordination mode stored in a memory unit (104) when coordinated transmission is started, and performs inter-base station coordination control again with the other base station in order to execute a newly selected coordination mode when the coordination mode selected by the coordination mode selection unit (112) is changed.
