Abstract
A communications node (FIG. 1, 5) communicating with an individual subscriber unit (80) determines that a nominal-load condition exists. The communications node (5) then reduces the number of elements of the transmit and receive phased array antennas (10, 60) used to form receive and transmit communication beams. This reduces the amount of power required by the transmit and receive digital beamformers (15,50) which control the transmit antenna (10) and the receive antenna (60). In order to maintain the radio link with the individual subscriber unit (80), the communications node (5) adjusts the modulation characteristics of the radio link between the communications node (5) and the individual subscriber unit (80). This compensates for the loss of the antenna elements and thus reduces the power consumption of the transmit and receive phased array antennas (10, 60) under nominally-loaded conditions.
