A technique for steering a directional antenna such as may be used with
User Equipment (UE) in a wireless communication system. Optimum angle
settings for the directional antenna are determined as different values
for an uplink and downlink; that is for simple reception and simple
transmission. Thus, rather than determine compromised directions that are
picked in an attempt to optimize transmission and reception with the same
directional setting, directional settings may be optimized independently.
The invention is of particular use in a Time Division Duplex (TDD) system
where transmit and receive functions can be operating independently at
different times. In further aspects, an optimum direction is determined
by estimating an interference signal power which is detected from signals
emanating from adjacent base stations (access points) and determining a
directional setting that minimizes interference to adjacent cells based
upon such measurements. A further level of sophistication in antenna
angle setting, is to monitor the loading of adjacent cell sites base
stations and turning interference and determine the settings accordingly
to minimize interference to such heavily loaded neighbors. Further
aspects of the invention adapts to acquisition modes that accommodate the
directional setting in active use of the system.
