Patent ID: 8902840

Claim:
A method for supporting transmission of data in a multi-input-multi-output communication system to one or more terminals, the method comprising: receiving a signal comprising information to be wirelessly transmitted to one or more terminals, the information comprising at least one of audio, video, or broadband Internet communications; and transmitting the information via a plurality of frames, the plurality of frames comprising: preamble portions transmitted over a plurality of sets of Orthogonal Frequency Division Multiplexing (OFDM) subcarriers via a corresponding plurality of antennas, sequential ones of the frames comprising different sets of the OFDM subcarriers in the preamble portions transmitted over the plurality of antennas, the preamble portions to repeat the sets of OFDM subcarriers when each of the plurality of antennas has transmitted each of the OFDM subcarriers; and data portions including the information and transmitted over subsets of the OFDM subcarriers via subsets of the antennas, the subsets of the OFDM subcarriers being assigned to the subsets of antennas based on feedback information determined from the preamble portions of the corresponding ones of the frames, wherein the information is transmitted using transmission parameters derived based on the feedback information, the transmission parameters are selected to reduce a transmission power or increase a transmission rate to at least one of the terminals, and the feedback information is determined via a maximum ratio combining receiver.
