Abstract:
1. A method, in a communication system, of generating and causing to be transmitted data units conforming to a first physical layer (PHY) mode and data units conforming to a second PHY mode different than the first PHY mode, wherein the communication system utilizes a plurality of channels for transmitting data units conforming to the first PHY mode, and wherein each channel of the plurality of channels has a first bandwidth, the method comprising: generating a first data unit conforming to the first PHY mode, wherein generating the first data unit includes generating a first series of orthogonal frequency division multiplexing (OFDM) symbols; causing the first data unit to be transmitted via a channel of the plurality of channels; generating a second data unit conforming to the second PHY mode, wherein determining a frequency band for transmitting the second data unit, wherein causing the second data unit to be transmitted via the determined frequency band.
