发明名称 METHOD AND APPARATUS FOR BEAMFORMING IN OFDM WIRELESS SYSTEMS
摘要 <p>Systems and methods are disclosed for use in a wireless network that promotes simultaneous beamforming. These systems and methods include determining the Channel Quality Indicator (CQI) and Best Beam Index (BBI) for communications between a plurality of mobile stations and a base station, ranking the plurality of mobile stations in a list according to the determined CQI and BBI, and selecting a subset of the plurality of mobile stations for simultaneous beamformed communications. These systems and methods may also include verifying that the selected subset of the plurality of mobile stations does not have a conflict and initiating beamformed communications. Certain embodiments of the BBI may be determined based on a predetermined codebook, which is a function of an antenna configuration, such as a uniform linear array (ULA) and a uniform circular array (UCA).</p>
