Embodiment

[0275] In one embodiment, a method includes receiving white space spectral data from a white space data repository server. In one embodiment, the white space spectral data includes available frequency range data. The method also includes storing supplemental spectrum usage data and receiving a channel inquiry message. The method also includes transmitting a channel reply message containing at least one preferred frequency range data. At least one preferred frequency range data is determined based in part on the white space spectral data and the supplemental spectral usage data.

[0276] In some embodiments, the method further includes receiving a channel reply message indicating channel selection.

[0277] In some embodiments, the at least one preferred frequency range data includes a channel list.

[0278] In some embodiments, the channel list includes channel preference information.

[0279] In some embodiments, the method further includes receiving a channel acknowledgm...

Abstract

Systems and methods for dynamic white space management are described. First, local handling of channel queries, in which a channel query by a white space device (WSD) is handled by a local dynamic spectrum management (DSM) server, if the DSM server has all the information necessary for providing a response to the channel query. Second, a search extension, in which a WSDB passes part of a search for available channels to a local DSM server. Third, assisting of an available channel calculation, in which a DSM server provides spectrum sensing information to WSDBs to improve the available channel calculation within the WSDBs. And fourth, dynamic bandwidth management to meet the coexistence requirements. In addition, the content of the messages and procedures that enable the above value-adding functions and interactions with the WSDB systems are described.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application No. 61 / 332,004, filed May 6, 2010, and U.S. Provisional Application No. 61 / 362,581, filed July 8, 2010, the contents of which are hereby incorporated by reference is merged here. technical field [0003] This application relates to wireless communications. Background technique [0004] In the United States, 408MHz of the spectrum from 54MHz to 806MHz is allocated for television (TV). Currently, 108MHz of this spectrum is being redeveloped for commercial operation through auction or for public safety applications. The remaining 300MHz of this wireless spectrum will be reserved for dedicated use for over-the-air TV operations. Part of this 300MHz resource is reserved unused. The amount and exact frequency of unused spectrum varies from one location to another. These unused parts of the spectrum are called TV White Space (TVWS). The Federal Communic...
