Method for transmitting precoded signal in collaborative multiple-input multiple-output communication system

摘要

A method for transmitting a precoded signal in a collaborative multiple-input multiple-output (MIMO) communication system is described. A method for receiving a precoded signal in a MIMO communication system includes estimating, by a mobile station, channels for one or more base stations through signals received from the one or more base stations including a serving base station, transmitting precoding matrix indexes of the one or more base stations determined based on the estimated channels to the serving base station, and receiving signals precoded by the one or more base stations based on the precoding matrix index.

1. A method for improving throughput of receiving signals by a mobile station in a collaborative multiple-input multiple-output (MIMO) communication system, the method comprising:
estimating, by the mobile station, channels for each of a serving base station and at least one neighboring base station; determining, by the mobile station, precoding matrix indexes (PMIs) corresponding to each of the serving base station and the at least one neighboring base station based on the estimated channels; and transmitting, by the mobile station, the precoding matrix indexes to the serving base station; and receiving, by the mobile station, signals including same data from the serving base station and the at least one neighboring base station, wherein the signals are precoded by precoding matrixes corresponding to the precoding matrix indexes and are multiplied by values associated with phase information for the at least one neighboring base station.
