1. In a wireless communication system in which a remote station transmits a reverse link signal comprising a plurality of subchannel signals, a power control subsystem located in a base station for independently adjusting the transmission power of one or more of said plurality of subchannel signals, comprising:

  • a receiver that receives said reverse link signal;

    a demodulator that demodulates said reverse link signal to provide said plurality of subchannel signals, including;

    a PN demodulator that demodulates said reverse link signal in accordance with a pseudorandom noise (PN) sequence to provide a remote station signal; and

    a plurality of orthogonal demodulators, each of which receives said remote station signal and demodulates said remote station signal in accordance with an orthogonal demodulation sequence to provide a corresponding one of said subchannel signals; and

    a message generator that generates a power control message for adjusting the transmit power of at least one of said plurality of subchannel signals in accordance with a quality measurement or an energy measurement associated with a corresponding one of said subchannel signals.
