Locating a Source of Wireless Transmissions from a Licensed User of a Licensed Spectral Resource
First Claim
1. A method of operating own mobile communication system equipment to locate a transmitter that is using a spectral resource, wherein the own mobile communication system equipment includes a serving base station that serves at least one user equipment, the method comprising:
- operating the serving base station to receive, from each one of two or more remote sensors, sensing information from which transmitter location information can be determined, wherein the transmitter location information is oriented in a coordinate system used by the serving base station and wherein the remote sensors include at least one user equipment;
determining one or more geographical safety margins from the transmitter location information; and
adjusting transmissions from the serving base station to limit transmitting signals into a geographical area bounded by the one or more geographical safety margins.

Abstract
Own communication equipment locates a source of wireless transmissions, the own equipment including a serving base station (BS). The serving BS receives, from remote sensors including at least one user equipment (UE), sensing information from which transmitter location information (“location information”) can be determined. The location information is oriented in a serving BS coordinate system. The location information can comprise white space sensing information from which a direction of a transmitter relative to a position of the UE can be determined, and pilot signal sensing information from which respective directions of one or more BSs relative to the position of the UE can be determined. The BS transforms the white space and pilot signal sensing information into the location information. Geographical safety margins are determined from the location information, and BS transmissions are adjusted to limit transmitting signals beyond the geographical safety margin area.
