摘要： An apparatus and method for allocating transmission power of a subchannel for each individual user in an orthogonal frequency division multiple access (OFDMA) system. The apparatus and method comprises determining the number-of-transmission bits per symbol approximating an estimated signal-to-interference ratio (SIR) for each of subchannels when transmission power is uniformly allocated to the subchannels; and calculating a required SIR corresponding to the number-of-transmission bits per symbol, and allocating transmission power to each of the subchannels according to the required SIR.

摘要： A transmission and reception apparatus and method for use in a wireless communication system, and an apparatus and method for adaptively transmit and receive a signal according to channel state in a wireless communication system. An apparatus for adaptively performing transmission according to a state of a channel transmitted from a transmitter to at least one receiver includes a signal to interference ratio estimator for estimating a signal to interference ratio of the channel using a signal transmitted from the at least one receiver; and an adaptive transmitter for transmitting data to the at least one receiver on a basis of the estimated signal to interference ratio.
