PEER TO PEER WIRELESS FUNCTIONALITY BETWEEN DEVICES USING WHITE SPACES

摘要

A method for enabling peer to peer (P2P) transmission between a first geo-location database dependent (GDD) station (STA) and a second geo-location database dependent (GDD) station (STA) on a television white space (TVWS) frequency band includes: utilizing the first GDD STA to communicate with a geo-location database (GDB) to retrieve information of available TVWS channels and corresponding power constraints from the GDB; sending a TVWS action frame by the first GDD STA, wherein the TVWS frame includes this information; selecting a plurality of specific channels from the plurality of available TVWS channels to listen for GDD STAs including the second GDD STA; and when the second GDD STA and the first GDD STA are both listening on a same specific channel, beginning P2P communication between the first GDD STA and the second GDD STA.

1. A method for enabling peer to peer (P2P) communication between a first geo-location database dependent (GDD) station (STA) and a second geo-location database dependent (GDD) station (STA) on a television white space (TVWS) frequency band, the method comprising:
utilizing the first GDD STA to communicate with a geo-location database (GDB) to retrieve information of available TVWS channels and corresponding power constraints from the GDB; sending a TVWS action frame by the first GDD STA, wherein the TVWS action frame contains the information; selecting a plurality of specific channels from the plurality of available TVWS channels to listen for GDD STAs including the second GDD STA; and when the second GDD STA and the first GDD STA are both listening on a same specific channel, beginning P2P communication between the first GDD STA and the second GDD STA.
