Embodiment

[0170] 1. A Dynamic Spectrum Management (DSM) engine, the DSM engine comprising: a policy engine configured to maintain policy and opportunistic spectrum availability information.

[0171] 2. The DSM engine of embodiment 1, further comprising: a channel management function (CMF) linked to the policy engine and configured to obtain opportunistic spectrum resource information from at least the policy engine to maintain a pool of opportunistic spectrum resources , perform radio resource management (RRM) and allocate aggregated spectral resources in response to requests from devices that have been granted by the CMF.

[0172] 3. The DSM engine of any preceding embodiment, wherein the CMF further includes a control channel management function configured to send aggregated spectral resources to the device, and to dynamically update and renew Configure aggregated spectrum resources.

[0173] 4. The DSM engine of any preceding embodiment further comprising a Sensing Processor (SP), w...

Abstract

Described herein are methods, apparatus and architecture for dynamic spectrum management (DSM) including protocol stacks, logical entities and functionalities that support DSM operation in opportunistic spectrum such as television white space (TVWS). The architecture supports aggregating bandwidth at the internet protocol (IP) layer over licensed and opportunistic bands as well as noncontiguous spectrum aggregation at the medium access control (MAC) layer. The control plane protocol stack includes a multi network transport protocol (MNTP), a channel management (CM) protocol, a policy protocol, a medium access control (MAC) entity, a physical entity and an air interface, all of which are configured to allocate, monitor, and update aggregated spectrum resources with respect to a DSM client.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims the benefit of US Provisional Application No. 61 / 391,901, filed October 11, 2010, the contents of which are incorporated herein by reference. technical field [0003] This application relates to wireless communications. Background technique [0004] Dynamic Spectrum Management (DSM), also known as Dynamic Spectrum Access, can allow spectrum access by cognitive radios when Primary Spectrum Users (PUs) are not using the spectrum, resulting in better spectrum usage and improved system performance . Devices in a DSM system that can access the PU's spectrum when the PU is not using the spectrum are called Secondary Spectrum Users (SU). [0005] Local area wireless networks are often bandwidth constrained as more bandwidth-hungry wireless applications are deployed in the home or office. To solve this problem, it is necessary to operate in new and emerging spectrums such as television white space (TV...
