Abstract: Techniques are provided for more efficiently determining frequency spectrum to allocate to General Authorized Access (GAA) citizens broadband radio service device(s) (CBSD(s)). Efficiency is enhanced by forming interference groups. Each of interference group may be analyzed in parallel and substantially contemporaneously, e.g., using parallel processing.

Abstract: Techniques are provided for accurately determining actual and prospective location(s) of radio(s) located in a structure and controlled by a shared spectrum system. By more accurately knowing the location(s) of the radios, the shared spectrum system can more efficiently allocate maximum transmission power(s) to the radio(s), enhance corresponding radio coverage area(s), and/or diminish interference to other radio(s) and/or primary user(s).

Abstract: Techniques for planning locations of receiver systems for an environmental sensing capabilities (ESC) system are provided. An ESC system is used to detect activity of primary users in shared spectra. The techniques can be used to reduce dead zone area(s), created by the receiver systems, for radios of secondary systems using the shared frequency spectrum.

Abstract: A method is provided. The method comprises: booting a system; determining if the system has properly booted; if the system has properly booted, then initiating communications with the at least one DC-DC voltage converter system that is configured to power at least one remote radio head; determining if communications have been established with the at least one DC-DC voltage converter system; and if communications have been established, then supplying a higher voltage from the system.

Abstract: A system and method for determining the location of a target mobile device in a communications network. A set of mobile devices in proximity to the target mobile device may be determined (210) as a function of a common parameter of information observed by mobile devices in the set. Measurement data may be shared (220) for the set of mobile devices and the target mobile device, and a location of the target mobile device (230) determined as a function of the shared measurement data. This sharing of measurement data may occur amongst the set of mobile devices and the target mobile device or may also occur at a communication network entity.

Abstract: A method for diminishing passive intermodulation (PIM) is provided. The method comprises: upsampling an uplink baseband modulated signal; upsampling a downlink baseband modulated signal; determining a time delay for the upsampled downlink baseband modulated signal; time delaying the upsampled downlink baseband modulated signal by the determined time delay; estimating a third order PIM distortion (PIMD) product by filtering the time delayed, upsampled downlink baseband modulated signal with a third order power series kernel; generating a first filtered signal by subtracting the estimated third order PIMD product from the upsampled downlink baseband modulated signal; estimating a Nth order PIMD product by filtering the time delayed, upsampled downlink baseband modulated signal with a Nth order power series kernel; generating a nth filtered signal by subtracting the estimated Nth order PIMD product from the n−1th filtered signal; and downsampling the nth filtered signal.
