Downlink signal processing in CDMA systems utilizing arrays of antennae

An article of manufacture containing a machine-readable medium having stored thereon data representing sequences of instructions which, when executed by a processor, cause the processor to perform operations comprising:

• transmitting a plurality of test pilot signals from a first base station (BS) of a system to a subscriber unit (SU), the system including the first BS and a number of other base stations, each test pilot downlink signal processed with a different weight set from the other test pilot downlink signals, at least one of the plurality of the test pilot downlink signals comprising a CDMA pilot signal associated with the first BS, and at least one of the plurality of test pilot downlink signals comprising a CDMA pilot signal associated with one of the other, non-neighboring base stations;
• receiving a report signal from the SU for at least one of the test pilot downlink signals;
• and
• selecting a weight set from the plurality of weight sets based, at least in part, on the received report signal.

A method to determine an antennae array weight set corresponding to a subscriber unit (SU) for communications between the SU and a first base station (BS) of a system, the system including the first BS and a number of other base stations, the method comprising:

• transmitting a plurality of test pilot downlink signals from the first BS to the SU, each test pilot downlink signal processed with a different weight set than the other test pilot downlink signals, at least one of the plurality of test pilot downlink signals comprising a pilot signal associated with the first BS, and at least one of the plurality of test pilot downlink signals comprising a pilot signal associated with one of the other base stations that is typically used for at least one of controlling power and base station hand off, the one of the other base stations being sufficiently spatially separated from the first base station to not produce interference between the first BS and the SU;
• receiving a report signal from the SU for at least one of the pilot downlink signals;
• and
• determining the weight set corresponding to the SU based on the report signal.
