Abstract: This disclosure is directed to spectrum reclaiming in a leased spectrum system. A spectrum exchange coordinator (SEC) may be interposed between a spectrum owner and at least one operator to facilitate the leasing and reclaiming of spectrum. Upon occurrence of a trigger, the SEC may then determine a procedure for allowing the spectrum owner to reclaim the leased spectrum. The spectrum owner may be allowed to reclaim the leased spectrum in full based on an agreement. If not previously agreed to, the spectrum owner may be allowed to reclaim at least part of the spectrum. These operations may include a dual risk evaluation to determine how reclaiming the leased spectrum will affect quality of service (QoS). Partial or gradual reclaiming may then allow the leased spectrum to be reclaimed while minimizing impact. Examples of gradual reclaiming may be based on a time domain, frequency domain, or cellular basis.

Abstract: Systems, methods, and apparatuses are directed to coordination of spectrum usage rights among entities. In one embodiment, logic may be configured to receive, from a first entity, spectrum information relating to a first frequency range available for allocation, and store the spectrum information in a database. The logic may also be configured to receive a request for allocation of at least one frequency range to a second entity, and query the database for at least one frequency range available for allocation to the second entity based on the allocation request. The logic may further be configured to determine that the first frequency range is available to satisfy the allocation request based on the query and the storage of the spectrum information, and allocate the first frequency range to the second entity based on the determination that the first frequency range is available to satisfy the allocation request.
