Abstract: A system and method for determining transmission delay in a communications system. In some embodiments, satellite positioning information having System Frame Number (SFN) information may be received for a mobile device and observed time difference of arrival (OTDOA) measurements may be received for a mobile device. A location of the mobile device may be determined as a function of the received satellite positioning information. A Global Positioning System (GPS) time estimate may be determined as a function of the determined location of the mobile device. Transmission delay between a node serving the mobile device and an antenna serving the mobile device may be determined as a function of the received OTDOA measurements and determined GPS time estimate.

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: A system for ESC protection includes a spectrum access system (SAS) configured to allocate a frequency band in the system and at least one Citizens Broadband Radio Service device (CBSD) communicatively coupled to the SAS and configured to provide wireless service to UEs. The system also includes at least one ESC communicatively coupled to the SAS and configured to detect RADAR signals from offshore RADAR devices. The SAS is configured to assign grants to the at least one CBSD such that the aggregate signal energy received at the ESC does not cross an overload threshold, as calculated by the SAS. The ESC is configured to detect an aggregate signal energy received at the ESC, and trigger, in response to the aggregate signal energy exceeding the overload threshold, an operation that suspends transmission of at least one CBSD or moves at least one CBSD to a different frequency channel.

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.
