Abstract:
1. A method of wireless communication, said method comprising: determining, by a base station, whether more than one antenna is associated with subscriber station; determining, by said base station, the mobility of said subscriber station; determining, by said base station, the position of said subscriber station; determining, by said base station, either spatial orthogonality of the signal of said subscriber station or whether a Line of Sight (LOS) condition is associated with said subscriber station; selecting, by said base station, a multiple antenna communication scheme based upon said determination of mobility, said determination of position, and said determination of said spatial orthogonality when more than one antenna is not associated with said subscriber station or said LOS condition when more than one antenna is associated with said subscriber station; and determining whether a Line of Sight (LOS) is associated with said subscriber station and selecting Multiple-Input Multiple-Output (MIMO) for a communication mode if said subscriber station is determined to be associated with more than one antenna, not fast-moving, closer to said base station, and not associated with said LOS condition.
