Patent ID: 8340032

Claim:
A method of transmitting data in a wireless communication system, the method comprising: receiving, at a transmitter, a feedback comprising a first group index and a second group index, wherein the first group index represents indices of a subcarrier group having channel power below a specified threshold value and the second group index represents indices of a subcarrier group having channel power greater than or equal to the specified threshold value; and transmitting remapped data to a receiver, after swapping mapping locations between the subcarrier group associated with the first group index and the subcarrier group associated with the second group index, wherein a channel fading is controlled by the swapping of the mapping locations between the subcarrier group associated with the first group index and the subcarrier group associated with the second group index, in accordance with a number of swapped mapping locations, and wherein the channel power is compensated in accordance with the following equation: | H n | 2 =|H n | 2 +|Ξ n | 2 , where |H n | 2 denotes a receiving channel power of an n th subcarrier, |Ξ n | 2 denotes an amount of change in channel power according to the receiver's mobility, and | H n | 2 denotes a channel power value compensated by the amount of change in channel power.
