DYNAMIC SPECTRUM MANAGEMENT
First Claim
1. A wireless transmit/receive unit (WTRU) comprising:
- a transceiver configured to communicate over a wireless link;
a radio frequency (RF) spectrum sensing unit configured to measure information indicative of usage of a spectrum by other devices; and
a processing unit configured to;
detect a change in performance of the wireless link,on a condition that the processing unit detects the change in performance of the wireless link, control the transceiver to transmit a notification to a DSM engine indicating that the change in the performance of the wireless link was detected, andreceive 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.

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, 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.

6. A method implemented in a dynamic spectrum management (DSM) engine, the method comprising:
-
allocating spectrum for use by a plurality of wireless transmit/receive units (WTRUs); receiving a notification from one of the plurality of WTRUs indicating that the one of the plurality of WTRUs detected a change in performance of a wireless link corresponding to use of the spectrum by a primary user of the spectrum; and in response to receiving the notification, transmitting a sensing task request to at least one of the plurality of WTRUs requesting the at least one of the plurality of WTRUs to measure information indicative of usage of the spectrum by other devices. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
