摘要： A method for use in a Dynamic Spectrum Manager (DSM) for coordinating asynchronous silent periods in a network, the method comprising detecting a primary user in the network, transmitting a Silent Period Start Control Message to one or more cognitive radio (CR) nodes in the network, wherein the message indicates the start and duration of a silent period and initiates spectrum sensing, receiving a Measurement Report Control Message from the one or more CR nodes in the network indicating results of spectrum sensing, and transmitting a message to the one or more CR nodes, wherein the message instructs the one or more CR nodes to move to a different frequency based on the spectrum sensing results.

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： Described herein are methods, metrics and apparatus for bandwidth allocation for cognitive radio. Information that needs to be passed between different components of a dynamic spectrum management (DSM) system for dynamic bandwidth allocation along with the corresponding interfaces is identified. Methods and associated metrics for measuring network performance, evaluating channel sensing results and handling various bandwidth allocation scenarios are presented. Also provided is an admission control mechanism for quality of service support. Alternate channel monitoring may be performed in the background so that when a new channel is needed, an alternate channel may be immediately allocated and service disruption to the DSM system is reduced. A channel may be dynamically assigned as the primary channel in multiple channel scenarios to support tasks such as transmission of acknowledgment frames. Hybrid mode devices that may access a television white space (TVWS) database and perform spectrum sensing are also described.

摘要： A method and apparatus for operating supplementary cells in licensed exempt (LE) spectrum. An aggregating cell operating in a frequency division duplex (FDD) licensed spectrum is aggregated with a LE supplementary cell operating in a time sharing mode for uplink (UL) and downlink (DL) operations. The LE supplementary cell may be an FDD supplementary cell dynamically configurable between an UL only mode, a DL only mode, and a shared mode, to match requested UL and DL traffic ratios. The LE supplementary cell may be a time division duplex (TDD) supplementary cell. The TDD supplementary cell may be dynamically configurable between multiple TDD configurations. A coexistence capability for coordinating operations between the LE supplementary cell with other systems operating in the same channel is provided. Coexistence gaps are provided to measure primary/secondary user usage and permit other systems operating in the LE supplementary cell channel to access the channel.
