    摘要: 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.

    摘要: A method and apparatus are described for synchronizing a network. A plurality of existing nodes in the network may transmit beacons in accordance with a round-robin scheduling sequence. A new joining node may receive a beacon from a specific one of the existing nodes during a beacon interval, and transmit a join beacon frame during the beacon interval after waiting a random period of time. The specific existing node may receive the join beacon frame and transmit a notification to the other existing nodes in the network indicating that a new node is joining the network. Alternatively, the existing nodes may transmit a primary synchronization sequence (PSS) and a secondary synchronization sequence (SSS). After a new node receives the PSS and SSS from a specific one of the existing nodes, the new node may generate a random access channel (RACH) preamble indicating that it desires to join the network.
