Abstract

See full text

An antenna apparatus operates as a base station in a wireless network with spatial nulling performed within such apparatus. The apparatus has an antenna assembly employing a selected reception beam pattern. During a nulling test, a reception beam pattern controller causes the assembly to employ each reception beam pattern. Quality metric determination circuitry determines for each reception beam pattern a link quality metric for each of several wireless terminals, based on communication between those wireless terminals and the base station while the assembly employs that reception beam pattern. Reception beam determination circuitry determines, from the various link quality metrics, a reception beam pattern from the reception beam patterns for use for subsequent communication with the wireless terminals. A reception beam pattern can be altered seeking to reduce interference source effects and to maintain an appropriate level of link quality regarding each wireless terminal communicating with the base station.
