Channel reporting for television whitespace

摘要

Various technologies described herein pertain to providing spectrum utilization feedback from a whitespace device. A database query for a set of available channels in a spectrum (e.g., broadcast spectrum, etc.) during a time period can be transmitted from the whitespace device to a regulatory authorized database system. The database query includes data that specifies a set of channels used by the whitespace device during a previous time period prior to the time period. Responsive to the database query, a response can be received at the whitespace device from the regulatory authorized database. The response indicates the set of available channels in the spectrum during the time period, where the available channels are unassigned to licensees at a location of the whitespace device during the time period. Moreover, the whitespace device is configured to opportunistically communicate in the spectrum over one or more of the available channels.

主权项

1. A whitespace device, comprising:
at least one processor; and memory that comprises computer-executable instructions that, when executed by the at least one processor, cause the at least one processor to perform acts including:
transmitting a database query for a set of available channels in a spectrum during a time period, the database query being transmitted for execution on a regulatory authorized database, wherein the spectrum is allocated by a telecommunications regulatory body;receiving, responsive to the database query, a response that indicates the set of available channels in the spectrum for the whitespace device during the time period, wherein the available channels in the set are unassigned to licensees at a location of the whitespace device during the time period;receiving channel usage data for the set of available channels in the spectrum, the channel usage data specifies actual usage of the spectrum by at least one disparate whitespace device prior to the time period respectively reported by the at least one disparate whitespace device when querying the regulatory authorized database; andcontrolling usage of one or more of the available channels in the spectrum by the whitespace device during the time period based on the channel usage data.
