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.

Abstract: A method for detecting interference in a wireless system is disclosed. The method includes receiving an uplink signal at a remote radio head in a distributed base station, passing the uplink signal from the remote radio head to a baseband unit over a front-haul communication link as baseband IQ data, and intercepting the baseband IQ data at a tester coupled between the remote radio head and the baseband unit. Processing of the IQ data is performed to determine whether an interfering signal is present in the uplink signal.

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 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: A system is provided. The system comprises a radio frequency (RF) planning system, comprising: a first processing system; a first communications system coupled to the first processing system; at least one input/output device coupled to the first processing system; wherein the first processing system comprises first memory circuitry and first processor circuitry; and wherein the first processing system is configured to: receive proposed RF access system design criteria; synthesize an RF access system design; assess interference using shared spectrum system data and data about the synthesized RF access system design; determine if the proposed RF access system design criteria are acceptable based upon the interference assessment; and if the proposed RF access system design criteria are unacceptable, then adjust the proposed RF access system design criteria.

Abstract: A method for detecting a physical cell identification (PCI) for a wireless coverage area is provided. The method includes establishing a hypothesis having a set of values including a number of subbands, a set of synchronization sequences, and a frequency offset; iteratively updating and testing the set of values against extracted baseband data until a current set of values results in frame synchronization; and decoding the physical cell identification based on the set of values that resulted in frame synchronization.
