Title:

COMMUNICATION CONTROL METHOD, USER TERMINAL, AND BASE STATION

Document Type and Number:

WIPO Patent Application WO/2013/129502

Kind Code:

A1

Abstract:

This communication control method is applied to a mobile communication system having a base station that uses a precoder matrix to transmit a precoded downlink signal via multiple antenna ports, and a user terminal that feeds back, to the base station, precoder matrix information indicating a precoder matrix optimal for use in the downlink. This communication control method includes a step in which, when feeding back the aforementioned precoder matrix information to the base station, antenna port information indicating antenna ports having a low degree of contribution during transmission from the base station is sent as notification from the user terminal to the base station.
