Estimating the term…
A base station acquires an arrival time at which a signal that is transmitted from a plurality of terminals arrives at a plurality of Remote Radio Heads (RRH) that are 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 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.
A method in which a base station that is connected to a plurality of Remote Radio Heads (RRH) that are installed within a cell performs uplink multiple user-multiple input multiple output (MU-MIMO) communication with a plurality of terminals, the method comprising:
An apparatus that enables a base station that is connected to a plurality of Remote Radio Heads (RRH) that are installed within a cell to perform uplink multiple user-multiple input multiple output (MU-MIMO) communication with a plurality of terminals, the apparatus comprising:
