Abstract: Channel access coordination for TXOP sharing An access point of a wireless communication system operates on a primary bandwidth part 5 (Ch2, Ch3) of a medium.

In response to the control message, the AP cooperates with the other AP by sharing the TXOP for performing one or more transmissions of data.
