Managing spectrum resources using channel maps and predicted noise floor

摘要

A central registration system provides channel maps of available spectrum channels to radio devices. The channel map indicates relative noise floor amounts among the available channels. For this purpose, an amount of predicted interference caused by high-power protected transmitters on each channel available to the requesting radio device for wireless communications is determined, where interference from primary channel and out-of-band emissions of the transmitters is considered.

主权项

1. A system for providing channel maps of available spectrum to radio devices, comprising:
an interface to communicate with the radio devices over a network; and a processor that executes a spectrum resource function that is stored in a memory and, by execution of the spectrum resource function, the system configured to:
receive a request for a channel map from one of the radio devices;determine channels that are available to the requesting radio device for wireless communications;determine, for each channel determined to be available, a predicted noise floor amount caused by high-power protected transmitters that are known to the system prior to receipt of the request, wherein the determination of predicted noise floor is made using a path loss model for a location of the requesting radio device, and wherein, for each predicted noise floor, interference from primary channel and out-of-band emissions of the transmitters is considered; andtransmit a channel map of the available channels to the requesting radio device, the channel map indicating relative predicted noise floor amount among the available channels.
