Abstract
A cellular base station transmitter/receiver system is provided which combines adaptive array processing, for the uplink RF signals, and fixed beam switching, for the downlink RF signals. An example of the configuration employs at least four antenna ports, with all four ports being used to provide uplink RF signals to a receiver processor, two being used to supply narrow beam uplink signals and two being used to supply wide beam uplink signals. Two of the four ports are used to provide beam switched narrow beam downlink RF signals.
