A method of providing channel state information feedback in a wireless communication system is provided. The method includes measuring original channel state information for each of a plurality of channels. An offset vector is applied to the original channel state information to generate modified channel state information. A subset of the channels is identified based on the modified channel state information. The original channel state information or the modified channel state information is reported.

Method and system for providing channel state information feedback in a wireless communication system

A method from transmitting data via multiple antennas. In this method, four information bits to be transmitted are multiplexed by using either one of a code division multiplexing scheme or a second code division multiplexing scheme combined with a real and imaginary multiplexing scheme, to generate a code division multiplexed symbol including four vectors. Then, the code division multiplexed symbol is repeatedly transmitted by alternatively applying two transmit diversity schemes via four transmission antennas.
