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

摘要

The base station obtains the arrival time at which the signals transmitted from the plurality of terminals arrive at the plurality of remote radio heads (RRH) installed in the cell, and transmits the plurality of And selecting RRHs to participate in reception of the uplink MU-MIMO from among the plurality of RRHs using the arrival delay time between the plurality of terminals and the plurality of RRHs, And adjusts the transmission time of the plurality of terminals using the arrival delay time between the plurality of terminals and the RRHs to participate in the reception of the uplink MU-MIMO.
