APPARATUS AND METHOD FOR COMMUNICATIG OF BASE STATION FOR MU-MIMO TRANSMISSION AND RECEPTION IN DISTRIBUTED ANTENNA SYSTEM

摘要

A base station acquires an arrival time at which a signal transmitted from a plurality of terminals arrives at a plurality of remote radio heads (RRH) installed within a cell, calculates an arrival delay time between the plurality of terminals and the plurality of RRHs using a predetermined reference time and an arrival time of the plurality of RRHs, selects RRHs to participate in receiving the uplink MU-MIMO among the plurality of RRHs by using an arrival delay time between the plurality of terminals and the plurality of RRHs, and adjusts a transmitting time of the plurality of terminals using an arrival delay time between the plurality of terminals and RRHs to participate in receiving the uplink MU-MIMO.
