Abstract: Disclosed embodiments include systems, methods, and a radio resource controller that may receive a request for radio resources from a user device. Disclosed embodiments may also determine a value ascribed to the requested radio resources. The ascribed value may reflect at least a qualitative or quantitative importance of the requested radio resources to a user of the user device. Additionally, disclosed embodiments may schedule radio resources based on the ascribed value.

Abstract: A method of allocating resources in a first wireless system, wherein the first wireless system shares a frequency spectrum with a second wireless system, is described. The method comprises detecting a level of interference to the second wireless system caused by the first wireless system on a first frequency within the spectrum; determining if transmission on the first frequency should be restricted based on the level of interference; and restricting transmissions in the first system on the first frequency if it was determined that transmission on the first frequency should be restricted while allowing normal use of the remaining portions of the frequency spectrum to continue in the first system. A system for allocating resources in a first wireless system, wherein the first wireless system shares a frequency spectrum with a second wireless system, is also described.

Abstract: An improved technique for detecting the presence or absence of one or more predetermined signals in a shared spectrum. In accordance with the disclosed embodiments, a received RF signal may be down-converted to a baseband signal, which is subsequently processed by a spectrum sensor to detect the presence or absence of a predetermined signal, such as a predetermined radar signal. The spectrum sensor may transform the baseband signal to the frequency domain, for example using a fast Fourier transform, to generate a corresponding set of frequency components. The spectrum sensor multiplies the frequency components of the baseband signal with the frequency response of a matched filter having a set of coefficients corresponding to the predetermined signal. The spectrum sensor may convert the matched-filter output signal to the time domain, for example using an inverse fast Fourier transform, and then may determine a value indicative of the signal power that it compares with a known threshold value. The spectrum sensor may determine the presence or absence of the predetermined signal in the received RF signal based on the result of the comparison, and may use the results of its determination to cause the reconfiguration of a transmitter that may be used to transmit RF signals in the same shared spectrum as the received RF signal.

Abstract: Methods are provided for managing frequency channels in a shared spectrum available to a radio local access network (RLAN) access point (AP) in a wireless network. The methods may comprise receiving a request for channel availability from the RLAN AP to access the shared spectrum, computing, based on a plurality of parameters associated with the RLAN AP, an RLAN service area (RSA) associated with the RLAN AP, retrieving one or more incumbent protection contours (IPCs) associated with one or more incumbent users in the wireless network, identifying an IPC, among the one or more retrieved IPCs, that overlaps with the RSA associated with the RLAN AP, determining, based on the identified IPC, available frequency information corresponding to the received request for channel availability, and transmitting, to the RLAN AP, a channel availability response comprising the available frequency information.

Abstract: Improved techniques are provided for managing frequency channels in a shared spectrum available to a radio local access network device (RLAN) in a wireless network. A shared spectrum system may perform operations including retrieving a plurality of parameters for one or more high-priority users in the wireless network; computing, based on the retrieved parameters, a plurality of interference-to-noise power ratio (I/N) contour values; storing the plurality of I/N contour values in a database; receiving, from the RLAN in the wireless network, a request for channel availability, wherein the received request includes at least a first value; extracting, based on the first value in the request for channel availability, I/N contour values from the database exceeding a threshold value; determining, based on the extracted I/N contour values, available frequency information corresponding to the received request for channel availability; and transmitting a channel availability response comprising the available frequency information.
