Abstract
A wireless device (AP1) contends for access to a medium. In response to gaining access to the medium, the wireless device (AP1) reserves a TXOP on the medium. Further, the wireless device (AP1) configures a set of resources (501, 502, 503) in the reserved TXOP to be available to at least one other wireless device (AP2, STA31) for one or more transmissions of data (D) arriving after beginning of the TXOP.

A method performed by an access point (AP) in a wireless communication system, the method comprising:
- transmitting a broadcast message indicating that a set of resources associated with a wireless medium will be kept available for certain wireless devices;
- prior to a transmission opportunity that includes the set of resources, receiving, from a wireless device, a request to participate as one of the wireless devices for which the broadcast message indicates that the set of resources will be kept available;
- and
- sending, to the wireless device, a response negotiating use of the set of resources as one of the wireless devices for which the broadcast message indicates that the set of resources will be kept available.
