Claim:
1. Antenna apparatus for operating as a base station in a wireless network, comprising: an antenna assembly to employ a reception beam pattern selected from a plurality of reception beam patterns; a reception beam pattern controller to cause the antenna assembly to employ each of said plurality of reception beam patterns during a nulling test operation; quality metric determination circuitry to determine, for each reception beam pattern employed during said nulling test operation, a link quality metric for each of a plurality of wireless terminals based on communication between the plurality of wireless terminals and the base station whilst the antenna assembly is employing that reception beam pattern; and reception beam determination circuitry to determine, from the link quality metrics determined for the plurality of wireless terminals for each of the plurality of reception beam patterns, a reception beam pattern from said plurality of reception beam patterns to be used for a subsequent communication with the plurality of wireless terminals.
