FRAME STRUCTURE OF SUPERFRAME TRANSMITTED IN WIRELESS NETWORK, METHOD FOR TRANSMITTING THE SUPERFRAME, AND METHOD FOR CONTROLLING DEVICES' WAKEUP BY USING THE SUPERFRAME

摘要

A PAL defined in a MAC of a wireless communication network, and more particularly, a superframe structure and a method of synchronization of wakeup periods among devices in the wireless communication network, is provided. The superframe transmitted/received in a WPAN includes: a LWS period field including period information of a superframe where a device is awake; and an LWS Countdown field including information of a number of remaining superframes to be transmitted until the superframe where the device is awake is transmitted.
