Abstract:
A method for ongoing power control for uplink communications between one or more remote transmitters and a communication station for receiving an uplink signal, the communication station including an array of antenna elements, each antenna element coupled to an associated receive apparatus, and a processor for spatial processing the set of signals from the set of receive apparatuses, the spatial processing forming the uplink signal according to a receive weight vector of receive weights, the method comprising, for a particular remote transmitter(a) setting up an initial power assignment for the particular remote transmitter on a conventional channel and transmitting a particular uplink signal from the particular remote transmitter on the conventional channel; (b) determining a particular receive weight vector for communicating with the particular remote transmitter on a spatial channel of the conventional channel; (c) receiving the particular uplink signal at the antenna elements and associated receive apparatuses as a set of received signals and spatially processing the received signals with the particular receive weight vector to form a particular received signal; (d) estimating the quality of the particular received signal; (e) determining an updated power assignment for the particular remote transmitter, the power assignment determination using the received signal quality estimate; and (f) applying the updated power assignment at the particular remote transmitter, the applying including transmitting a new uplink signal.
