Patent ID: 7720034

Claim:
A method for transmitting signals at a base station to a user equipment (UE) configured to operate in a multi input multi output (MIMO) mode, the method comprising: receiving, from the UE, feedback information comprising weight information to be used for data transmission; multiplying a weight and data to be transmitted, the weight being determined considering to the feedback information received from the UE; 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; and transmitting feed-forward information, indicating the weight applied to the data when transmitted to the UE, 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 downlink shared control channel, and wherein the feed-forward information, comprising the weight information indicating the weight applied to a specific subframe of the specific physical downlink shared channel, is transmitted through a subframe of the downlink shared control channel corresponding to the specific subframe of the specific physical downlink shared channel.
