Method and system enabling use of white space radio spectrum using digital broadcast signals
Abstract:
A system (10) and method (50 or 70) of dynamic allocation of spectrum for a communication device where a UHF band is currently unused for licensed television broadcasting involves determining (51) a location of a user device, determining (52) which UHF television broadcast channels are available for use by the user device and determining (53) a maximum allowed transmission power for a given channel based on signal strength for the given channel and on adjacent channels before transmitting (54) the maximum allowed transmission power and location by the user device to a remote server. The method can receive (55) polygon endpoints from a television broadcast defining the location of usable reception of the television broadcast.
Abstract(Chinese):

用于通信设备的频谱的动态分配的系统（10）和方法（50或70），其中UHF频带当前未被许可的电视广播包括确定（51）用户设备的位置，确定（52）哪个UHF 电视广播频道可由用户设备使用，并基于给定频道的信号强度和相邻信道确定（53）给定频道的最大允许传输功率，在发送（54）最大允许传输功率和位置之前 用户设备到远程服务器。 该方法可以从定义电视广播的可用接收位置的电视广播接收（55）多边形端点。
