摘要： A method and apparatus for power control in a wireless communication system are provided. A Mobile Station (MS) operation method for power control in a wireless communication system includes assigning an UpLink (UL) control channel to the MS from a Base Station (BS), determining a location to receive a Transmit Power Control (TPC) command based on the UL control channel, and receiving a TPC command in the determined location and increasing or decreasing transmit power, thus advantageously being capable of reducing an overhead for power control command assignment information.

摘要： An apparatus and method for transmitting and receiving information through a fast feedback channel in a broadband wireless communications system are provided. The apparatus includes a generator for generating a quasi-orthogonal signal stream corresponding to a codeword to be fed back, a plurality of mappers for mapping the quasi-orthogonal signal stream to a plurality of bundles in the fast feedback channel by using different mapping patterns, and a transmitter for transmitting the quasi-orthogonal signal stream mapped to the plurality of bundles.
