Abstract

A wireless transmit / receive unit (WTRU) and a dynamic spectrum management (DSM) engine are described. The WTRU includes a transceiver, a radio frequency (RF) spectrum sensing unit and a processing unit. The transceiver transmits over a wireless link. The RF spectrum sensing unit measures information indicative of usage of a spectrum by other devices. The processing unit detects a change in performance of the wireless link. The processing unit also controls the transceiver to transmit a notification to a DSM engine indicating that the change in the performance of the wireless link was detected on a condition that the processing unit detects the change in performance of the wireless link. The processing unit also receives a sensing task request for the WTRU to measure the information indicative of the usage of the spectrum by other devices based on the notification transmitted to the DSM engine indicating that the change in the performance of the wireless link was detected.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Patent Application No. 61 / 408,808, filed November 1, 2010, U.S. Provisional Application No. 61 / 410,712, filed November 5, 2010, and U.S. Provisional Application No. 61 / 410,712, filed December 15, 2010 The benefit of Application No. 61 / 423,419, the contents of each application are hereby incorporated by reference. Background technique [0003] Many wireless devices communicate with each other using a set of one or more radio frequency bands that are statically configured for their use. These devices may be referred to as incumbents (or primary users) of the spectrum they use. For example, cellular telephones are primary incumbents of spectrum licensed by their cellular operators and do not allow other devices to communicate using this spectrum unless it is registered with the corresponding cellular operator. Also, although specific frequency bands are allocated to ...
