Abstract:
A method and apparatus for operating within a white space band using a message indicating whether an available channel information is valid in the wireless system are disclosed. In a method for a first station (STA) to operate as an unlicensed device which is permitted to operate on an available channel within a White Space (WS) band of a wireless system, comprises: receiving a message indicating whether an available channel information of the first STA is valid from a second STA, wherein the available channel is a channel not used by a licensed device, wherein the message includes a Map ID of a current valid available channel information; and determining whether an existing available channel information of the first STA is valid by comparing a Map ID of the existing available channel information of the first STA with the Map ID included in the received message.
