Abstract

A wireless local area network (WLAN) protocol allowing a Transmit Opportunity (TXOP) holder to share the TXOP with other stations. An intent to share the TXOP is communicated to the Access Point (AP). Upon gaining channel access, the TXOP holder directly or indirectly communicates that the TXOP can be shared with other STAs, after which scheduling information (time and duration) are shared with the STAs. When the TXOP occurs, the STAs can access the channel at the time and for the duration specified, thus providing increased use of the TXOP to improve efficiency.
