Patent ID: 7907950

Claim:
A method of transmitting information in a wireless communication system, the method comprising: allocating a physical resource for a downlink fast feedback channel by a base station (BS), wherein the physical resource for the downlink fast feedback channel is different from a physical resource for a data channel; establishing a modulation pattern to the downlink fast feedback channel by the BS, wherein the modulation pattern corresponds to feedback information; and transmitting the modulation pattern to a mobile subscriber station (MSS), wherein a basic allocation unit of the physical resource for the downlink fast feedback channel is divided into six sub-groups with each of the six sub-groups including eight sub-carriers, wherein the modulation pattern includes a plurality of vector indexes, each of the plurality of vector indexes corresponding to one of the six sub-groups, and wherein each of the plurality of vector indexes indicates a modulation scheme applied to each of the eight sub-carriers of the corresponding sub-group.
