Patent ID: 8005131

Claim:
A method comprising: receiving uplink channel training information and information indicative of a predicted downlink channel response from a wireless user station, at a base station, wherein said information indicative of said predicted downlink channel response includes a difference between a predicted uplink channel response and said predicted downlink channel response, and information indicative of said predicted downlink channel response includes a response predicted for a time when a future multi-user Multiple Input, Multiple Output (MIMO) data transfer is scheduled to occur between said base station and a plurality of selected user stations; estimating an uplink channel response using said uplink channel training information; and performing a communication function using said uplink channel response and said information indicative of a predicted downlink channel response, wherein performing a communication function includes: re-generating said predicted downlink channel response and using said re-generated predicted downlink channel response within a selection process to select multiple wireless user stations for simultaneous servicing by said base station using the MIMO, and performing transmit beam forming for said wireless user station using a beam forming matrix derived from said re-generated predicted downlink channel response when said wireless user station is one of said selected wireless user stations.
