Abstract
A station, such as a point coordinator (PC) or a non-PC station, in a basic service set (BSS) in a wireless local area network (WLAN) includes a frame classification entity (FCE), a frame scheduling entity (FSE) and a QoS management entity (QME). The FCE contains at least one classifier entry with a virtual stream identifier (VSID) and a frame classifier. A received data frame containing in-band quality of service (QoS) signaling information is classified to a selected VSID contained in a classifier entry in a classification table based on a match between an in-band frame classification information contained in a received frame and a frame classifier contained in the classifier entry. The FSE has a frame scheduling table containing at least one entry containing a VSID and a QoS parameter set identified by the VSID and schedules a transmission opportunity (TO) for the classified data frame.
