Abstract:
1. A method for generating physical layer (PHY) data units for transmission via a communication channel, the method comprising: generating a plurality of first PHY data units that conform to a communication protocol and that are to be transmitted in accordance with a transmission configuration, wherein the transmission configuration corresponds to at least one of (i) one or more particular numbers of spatial streams, and (ii) one or more particular channel bandwidths, wherein the communication protocol specifies generating a second PHY data unit for transmission according to the transmission configuration, including determining, according to a second technique, a number of OFDM symbols to be included in a payload of the second PHY data unit, wherein the second PHY data unit is to be transmitted using an MCS excluded from the set of allowed MCSs, and generating the determined number of OFDM symbols to be included in the payload of the second PHY data unit.
