Method and apparatus for beamforming in OFDM wireless system
First Claim
1. For use in a wireless network, a method of performing simultaneously beamforming, the method comprising:
- determining the Channel Quality Indicator (CQI) 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;
selecting a subset of the plurality of mobile stations for simultaneous beamformed communications;
verifying the selected subset of the plurality of mobile stations do not have a conflict; and
initiating beamformed communications.

Abstract
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 the selected subset of the plurality of mobile stations do not have a conflict and initiating beamformed communications. BBI is determined based on a predetermined codebook, which is function of antenna configuration as shown in equation 2 and 5. Any other codebook use equations 2 and 5 as their subset can also be applied.

9. A wireless network comprising a plurality of mobile stations, the network comprising:
-
a first mobile station capable of beamformed communication with a first base station; and a second mobile station capable of simultaneous beamformed communications with the first base station, wherein at least one of the first and second mobile stations transmit information to the base station that promotes the simultaneous beamformed communication between the first mobile station and the base station. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. For use in a wireless network, a base station capable of simultaneous beamformed communication with a plurality of mobile devices, the base station comprising:
-
a computer readable medium comprising information related to at least one codebook that corresponds to an antenna configuration of the base station; a processor configured to access the computer readable medium and use the at least one codebook to provide simultaneous communication with a plurality of mobile stations; and a transceiver coupled to the processor;
wherein the transceiver comprises a plurality of transmit antennas and is configured to receive information from a plurality of mobile stations and transfer this information to the processor, and wherein the processor is configured to interpret the information, select a subset of mobile stations for simultaneous beamforming, and instruct the transceiver to allow for simultaneous beamforming with a plurality of mobile stations. - View Dependent Claims (18, 19, 20)
