Abstract

A wireless local area network (WLAN) includes at least one hybrid coordinator (HC) and at least one Quality of Service Station (QSTA). The HC transmits a schedule frame element (SEF). The WLAN also includes a clocking mechanism that sets a substantially absolute start time of a service interval. A method of synchronizing the HC and the QSTA includes transmitting a schedule element frame (SEF), and setting a substantially absolute start-time of a service interval, and a first transmitted frame element.
