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: 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 more accurately determining interference contribution at a point in a neighborhood of a time division duplexing (TDD) system operating in shared frequency spectrum. If at least one TDD radio, of a TDD system, is in the neighborhood, then determine a largest interference level, at the point in the shared frequency spectrum, by a TDD radio of the TDD system, where the TDD radio is in the region around the point. The largest interference level is selected as the aggregate interference contribution of the TDD system for interference analysis in the shared spectrum at the point.

Abstract: Techniques for modelling a radio network in a geographic region utilizing shared spectra are disclosed. Population data is obtained for the geographic region. A number of radios per channel in the geographic region, N?, is determined. Candidate geographic location for radios in the geographic region are determined. For every channel in the shared spectra, at least one of a static dataset and a dynamic dataset is determined. At least one set of output data, that is a statistical characterization of the radio network, is generated using at least one of the static dataset and the dynamic dataset, to aid in design of the radio network.
