Abstract:
A first communication device transmits a plurality of training signals to a second communication device via a communication channel. The first communication device receives feedback generated at the second communication device based on the plurality of training signals. The feedback includes steering matrix information for a plurality of orthogonal frequency division multiplexing (OFDM) tones and (ii) additional phase information corresponding to channel estimates obtained for the plurality of OFDM tone. The first communication device constructs, based on the steering matrix information, a plurality of steering matrices corresponding to the plurality of OFDM tones, and compensates, using the additional phase information, the plurality of steering matrices to reduce phase discontinuities between the OFDM tones. The first communication device steers, using the compensated steering matrices, at least one transmission via the communication channel to the second communication device.

Claim (Index 14):
The method of  claim 13 , wherein:\n the plurality of OFDM tones are spaced according to a first tone spacing corresponding to a first number of OFDM tones in an OFDM symbol; and steering the at least one transmission comprises using the compensated steering matrices to steer at least one OFDM symbol that corresponds to a second tone spacing corresponding to a second number of OFDM tone, wherein (i) the second tone spacing is smaller than the first tone spacing and (ii) the second number of OFDM tones is greater than the first number of OFDM tones.
