    摘要: A base station includes a receiver receiving feedback information including a preferred weight determined by a user equipment (UE); a processor multiplying a weight and data to be transmitted; a transmitter including two antennas and transmitting the weight multiplied data to the UE through a specific physical downlink shared channel where a MIMO transmission scheme for a HS-DSCH (High Speed Downlink Shared Channel) is applied, the transmitter transmitting feed-forward information through a downlink shared control channel when the data is transmitted using the MIMO transmission scheme for the HS-DSCH, wherein the weight applied to the specific physical downlink shared channel is adjusted at a subframe boundary of the specific physical downlink shared channel and the feed-forward information is transmitted through a subframe of the downlink shared control channel corresponding to the specific subframe of the specific physical downlink shared channel.

    摘要: A reference signal transmission method in a downlink MIMO system is disclosed. The downlink MIMO system supports a first UE supporting N transmission antennas among a total of M transmission antennas (where M>N) and a second UE supporting the M transmission antennas. The method includes transmitting, by a base station (BS), subframe-associated information which designates a first subframe in which data for the first UE and the second UE is transmitted and a second subframe in which data only for the second UE can be transmitted within a radio frame having a plurality of subframes, and transmitting the first subframe and the second subframe. Reference signals corresponding to antenna ports ‘0’ to ‘N−1’ of the N antennas are mapped to the first subframe, and reference signals corresponding to antenna ports ‘0’ to ‘M−1’ of the M antennas are mapped to the second subframe.
