PROTOCOLS FOR ENABLING MODE 1 AND MODE 2 DEVICES IN TV WHITE SPACE NETWORKS Russian patent published in 2015 - IPC H04W72/04 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to wireless communication and more specifically to operation in a television white space (TVWS) network. One exemplary method generally includes receiving, at an apparatus, a message with a field indicating a current version of an unused frequency spectrum map (e.g., a white space map (WSM)), the unused frequency spectrum map indicating channels usable for wireless communication; determining whether the current version of the unused frequency spectrum map is different from a previous version of the unused frequency spectrum map; and using a channel for wireless communication based on the determination. Another exemplary method generally includes accessing a database of available channels for a current location of an apparatus via a neighbouring portable or fixed enabling apparatus and enabling one or more portable dependent apparatus for the wireless communication via one or more of the available channels.

EFFECT: improved communication in a television white space network.
