摘要： A method, apparatus and system are provided for use in optimizing signal-to-noise ratios at remote wireless devices. A method can receive a signal over a reverse link, determine an angular power profile of the reverse link signal, and determine an antenna weighting vector for the forward traffic signal based on the angular power profile. The determination of the weighting vector can include retrieving the vector from a weighting vector table. Some methods identify boundaries of angular spreads and utilize pre-calculate weighting vectors according to the boundaries. An apparatus can include an antenna array, a wireless receiver that receives reverse link signals, a detector that detects an angular power profile of the signals, a controller that determines a weighting vector and applies the weighting vector to the antenna array when transmitting. Some embodiments are dependent on whether the forward link incorporates a common pilot or per-user pilot signal.

摘要： In order to increase a capacity, or a number of mobile stations (MSs), or users, that may engaged in concurrent communication sessions, a communication system is provided that schedules a different MS, or user, in each beam of multiple predetermined, fixed beams associated with a coverage area, in particular a sector. By simultaneously scheduling a user in each beam of the multiple beams, a performance and throughput of communication system is significantly increased over the prior art. In one embodiment of the present invention, a portion of a shared communication channel that is allocated to each MS is concurrently transmitted to each MS via a beam associated with the MS. In other embodiments of the present invention, voice channels, data channels, and control channels associated with each MS scheduled in a beam may be concurrently transmitted to each MS via the beam associated with the MS.
