Abstract: A method signals data in a channel of a network including multiple stations and an access point connected by a wireless channel. A station first requests access to the channel using a sequential coordinated channel access method of an access point. After the station receives permission to access the channel during a contention free period at a time corresponding to a sequence index value received by the station from the access point, the station transmits a resource request message to the access point to obtain a bandwidth allocation. In response, the station receives the bandwidth allocation, and the station can then transmit data during the contention free period according to the bandwidth allocation.
