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: Techniques are provided for planning frequency spectrum and power allocated to transmission points of a radio network that is controlled by a spectrum access system and shares spectrum with incumbents and/or other secondary users (e.g., external radio(s)). Techniques are also provided for managing communications between components of the radio network and the spectrum access system, and to allocate frequency spectrum and maximum transmission power to component(s) of a radio network.

Abstract: Systems and methods for automatic frequency coordination are provided. In one embodiment, an automatic frequency coordination (AFC) system for authorizing unlicensed operator utilization of a shared spectrum band comprising channels licensed to incumbent operators comprises: a processor coupled to a memory; and an exclusion zone calculator executed by the processor, the exclusion zone calculator configured to construct an exclusion zone for an incumbent receiver antenna operating on a licensed channel of the shared band, wherein the calculator is configured to construct the exclusion zone by: calculating a set of exclusion zone radiuses along a plurality of radials of a radial grid based on applying a moving average filter to interference power values calculated for a plurality of locations along a length of each of the radials; and applying an averaging filter to the exclusion zone radiuses to define the exclusion zone between the exclusion zone radiuses and the receiver antenna.

Abstract: Methods and apparatuses for determining an assignment of frequency channels to radios of a spectrum access system are provided and which result in at least one of: (a) an enhanced transmit power-bandwidth product or an enhanced probable transmit power-bandwidth product for all radios, (b) diminished interference between radios of different nodes, and (c) diminishing changes to frequency channels either requested by or previously assigned to radios.

Abstract: Techniques for determining power levels of radios, including a time domain duplexing (TDD) system, in shared frequency spectrum is provided. A TDD radio, of the TDD system, in a neighborhood having a largest interference contribution in the frequency spectrum at the point. Transmit power levels are determined for (a) the selected TDD radio, (b) other radios in the neighborhood that are not part of the TDD system, and (c) at least one radio in the TDD system that is not the TDD radio having the largest interference contribution in the frequency spectrum. Thus, interference margin may be fairly allocated to radios in neighborhood(s) about protection points.

Abstract: A computing device includes a processor and memory storing instructions that are executable to determine a median of a first mixture distribution. The instructions are also executable to determine a parent mean, a parent standard deviation, and boundaries for each of multiple segments in the first mixture distribution. The instructions are also executable to determine a segment mean and a segment second moment for each segment based on the parent mean, the parent standard deviation, and the boundaries for the respective segment. The instructions are also executable to determine a scaled probability for each segment. The instructions are also executable to determine a mixture mean and a mixture standard deviation for the first mixture distribution based on the segment mean, the segment second moment, and the scaled probability for each segment in the first mixture distribution.

Abstract: Techniques are provided for efficiently determining power allocation of radios utilizing shared spectrum by enhancing processing efficiency for determining aggregate interference levels in a region of points where aggregate interference must not exceed a threshold level. Processing efficiency is achieved by techniques identifying a subset of points in the region at which analysis must be performed.

Abstract: A method is provided. The method comprises: selecting a new protection point in a dynamic protection area; creating an initial sort list of radios; determining look angles; determining which look angle includes most radios in its main beam; determining a modified sort list and an initial move list for the determined look angle; determining a certain percentile of aggregate interference power spectral density at the new protection point for radios that are in a main beam for each of remaining look angles; sorting, by level of certain percentile of aggregate interference power spectral density, the remaining look angles; and generating a move list of radios.
