Abstract
Official abstract text for this publication.
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, 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, and 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.
First claim
Opening claim text (preview).
What is claimed: 1. A dynamic spectrum management (DSM) engine comprising: a transceiver configured to: transmit a first sensing task request to at least two of a plurality of wireless transmit/receive units (WTRUs) requesting that the at least two of the plurality of WTRUs measure information indicative of usage of spectrum by other devices, receive first sensing results from a first WTRU of the at least two of the plurality of WTRUs at a plurality of periodic intervals, and…
