Abstract

A first communication device determines, based on information included in a first packet received from a second communication device, i) an overall frequency bandwidth of an operating channel of a WLAN and ii) one or more punctured sub-channels for the operating channel. The first communication device transmits, via a plurality sub-channels included in the operating channel of the WLAN, the plurality of sub-channels not including any of the one or more punctured sub-channels, a second packet that includes an RTS frame to initiate a TXOP of the first communication device. The first communication device receives, via a subset of the plurality of sub-channels, a third packet that includes a CTS frame, determines that the subset of sub-channels is reserved for the transmit opportunity TXOP initiated by the first communication device, and transmit a fourth packet to the second communication device during the TXOP via the subset of sub-channels.
