  • Patent number: 11350424
    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.

  • Patent number: 11234135
    Abstract: Techniques are provided for managing frequency access in a shared spectrum available to a radio local access network (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) contours; storing the plurality of I/N contours in a database; receiving, from an RLAN device in the wireless network, a request for spectrum availability, wherein the received request includes at least a first value; extracting, based on the first value in the request for spectrum availability, an I/N contour from the database matching RLAN parameters; determining, based on the extracted I/N contour, available frequency information corresponding to the received request for spectrum availability; and transmitting, to the RLAN device, the available frequency information.

  • Patent number: 11212812
    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.

  • Patent number: 10128898
    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.
