DIRECTIONAL DISCOVERY PROTOCOL WITH COORDINATED CHANNEL SELECTION

摘要

A method and system for communication device discovery and coordination of data channel selection between a first device and a second device in a Wireless Personal Area Network (WPAN). The method includes transmitting a set of discovery beacon blocks (101) by the first and second devices in a discovery channel (100) using an asynchronous contention based medium access mechanism; scanning the discovery channel (100) by the first and second devices; and coordinating between the first and second devices to select a data channel by exchanging channel selection command frames (600) in the discovery channel using the asynchronous contention based medium access mechanism.
