Protocols for enabling mode 1 and mode 2 devices in TV white space networks
First Claim
1. A first apparatus for wireless communications, comprising:
- a processing system configured to determine a version of an unused frequency spectrum map, the unused frequency spectrum map indicating channels usable for wireless communications in a television white space (TVWS); and
a transmitter configured to transmit a message based on the determination with;
a field indicating the version of the unused frequency spectrum map, andan indication that the message is a contact verification signal (CVS).

Abstract
Certain aspects of the present disclosure provide techniques and apparatus for operating in a television white space (TVWS) network. One example 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 communications; determining whether the current version of the unused frequency spectrum map is different than a previous version of the unused frequency spectrum map; and using a channel for wireless communications based on the determination. Another example method generally includes accessing a database of available channels for a current location of an apparatus via a neighboring portable or fixed enabling apparatus and enabling one or more portable dependent apparatuses for the wireless communications via one or more of the available channels.
