Patent ID: 8665949

Claim:
A method for generating a physical layer (PHY) data unit for transmission via a communication channel, the method comprising: receiving first data and second data that correspond to a unit of audio, video, and/or image information; encoding and modulating the first data and the second data so that a resulting data rate of the first data is less than a resulting data rate of the second data, wherein encoding and modulating the first data and the second data includes modulating the first data according to a first constellation having a first number of constellation points, and modulating the second data according to a second constellation that differs from the first constellation at least by having a second number of constellation points higher than the first number of constellation points; parsing the first data and the second data to a plurality of spatial streams such that each spatial stream of the plurality of spatial streams includes only first data or only second data; and generating a single PHY data unit that includes the plurality of spatial streams.
