1. A method for ongoing power control for uplink communications comprising:

  • receiving a particular uplink signal as a set of received signals from a particular remote transmitter on a Code Division Multiple Access (CDMA) channel, the received signal associated with an initial power assignment corresponding to the particular remote transmitter;

    determining a particular receive weight vector for communicating with the particular remote transmitter on a spatial channel of the CDMA channel;

    spatially processing the received signals with the particular receive weight vector to form a particular received signal;

    estimating the quality of the particular received signal;

    determining an updated power assignment for the particular remote transmitter, the power assignment determination using the received signal quality estimate; and

    transmitting the updated power assignment to the particular remote transmitter and receiving a new uplink signal from the particular remote transmitter.
