摘要： A transceiver which includes amplifier operating as a power amplifier when amplifying a signal to be transmitted by the transceiver and as a low-noise amplifier when amplifying a signal received by the transceiver, and switching circuitry switchable to a first configuration in which the amplifier operates as a power amplifier, and to a second configuration in which the amplifier operates as a low-noise amplifier. The transceiver can be used in a relay station, or other station, operating in an Orthogonal Frequency Division Multiple Access (OFDMA) network. A method includes determining whether a station operating in an OFDMA network is to transmit a signal or receive a signal and providing the signal to an amplifier in the station so that the amplifier operates as a power amplifier or a low-noise amplifier based on the determination.
