Abstract
An apparatus and method for closed-loop signaling over multiple channels in a telecommunication system. Channel condition for each channel is obtained, and transmission power loading per channel is determined according to channel condition. The information bit streams is transmitted via the multiple channels over a plurality of transmitter antennas according to the power loading per channel.
Claims31
