Abstract: Described herein are systems and methods for telecommunications spectrum sharing between multiple heterogeneous users, which leverage a hybrid approach that includes both distributed spectrum sharing, spectrum-sensing, and use of geo-reference databases.

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: Methods and systems described herein relate to more optimally allocating and scheduling radio resources simultaneously in space, time and frequency to enhance user quality of experience (QoE) according to use context within the constraints of maximizing long term service provider revenue expectation for a given investment in radio access network infrastructure for improved radio resource management, such methods optionally including use of heat maps of user trajectories as a factor in a process for resource allocation.

Abstract: Described herein are systems and methods for sharing public safety network resources between public safety devices and commercial devices. A request for network resources is received from a commercial device for an application running on the commercial device. It is determined that the request is for a first type of traffic that is tolerant to time delays caused by resource fluctuations. Resources are allocated from a public safety network instead of resources from a commercial network, so that the commercial device can use resources from the public safety network.
