Patent ID: 8503408

Claim:
A base station for transmitting signals to a user equipment (UE) configured to operate in a closed-loop multi-antenna mode, the base station comprising: a receiver configured to receive, from the UE, feedback information indicating one or more preferred weights determined by the UE; a multiplier configured to multiply one or more weights and data; a transmitter comprising two antennas and configured to: transmit feed-forward information indicating the one or more weights to the UE through a downlink shared control channel as a procedure of multi-antenna operation for a HS-DSCH (High Speed Downlink Shared Channel), wherein the one or more weights are determined based on the feedback information; and transmit a signal including a product of the one or more weights and the data to the UE through a specific physical downlink shared channel where a multi-antenna transmission scheme for the HS-DSCH is applied, wherein the one or more weights applied to a specific subframe of the specific physical downlink shared channel are adjusted at a subframe boundary of the specific physical downlink shared channel, wherein 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, and wherein the one or more weights can be different from the one or more preferred weights.
