Bandwidth coding for channel bonding access
View Patent ↗Disclosed herein are techniques to provide an indication of bandwidth to establish a TxOP using channel bonding. An information element may be generated to include an RTS frame or a CTS frame and an indication of bandwidth in a parity portion of the information element. The indication of bandwidth may be included by using 16 bits of the parity bits of parity bytes for a PHY header of the information element.
