Abstract

Certain aspects of the present disclosure provide techniques and apparatus for signaling the bandwidth to be used for wireless communications using an RTS / CTS (Request to Send / Clear to Send) frame exchange, providing for bandwidths of at least 20 MHz, 40 MHz, 80 MHz, 160 MHz, or higher. This exchange of bandwidth information may be performed implicitly-by determining the channels in which the RTS / CTS frames are actually sent-or explicitly. In addition to this bandwidth information exchange, aspects of the present disclosure may also allow for Network Allocation Vector (NAV) protection in multiple channels. In this manner, the wireless medium may be reserved, and the transmission may be protected from hidden nodes.
