Systems and methods for backwards-compatible preamble formats for multiple access wireless communication
First Claim
1. A method of transmitting to two or more wireless communication devices, the method comprising:
- transmitting a first section of a preamble according to a first preamble format and a second section of the preamble according to a second preamble format, wherein the first section includes a first symbol and the second section includes a second symbol, wherein the first section is transmitted using a first phase shift keying format on the first symbol, wherein the second section is transmitted using a second phase shift keying format on the second symbol, and wherein the first phase shift keying format is different from the second phase shift keying format, wherein the first section informs devices compatible with the first preamble format to defer communicating, and wherein the second section includes tone allocation information, the tone allocation information identifying two or more wireless communication devices, a bandwidth for each member of a set of sub-bands spanning a communication bandwidth, and an assignment of a number of the sub-bands to each one of the identified two or more wireless communication devices; and
transmitting data to the two or more wireless communication devices simultaneously, the data contained on two or more sub-bands.
