摘要： A wireless transmit/receive unit (WTRU) may include one or more antennas and a first transceiver operatively coupled to the antennas. The one or more antennas and the first transceiver may be configured to receive a first signal from a network using zero energy from the WTRU. The one or more antennas and the first transceiver may be further configured to extract energy from the first signal. The first transceiver may be further configured to examine a separation between energy threshold events to decode an energy signature of the first signal. The first transceiver may be further configured to activate a second transceiver operatively coupled to the one or more antennas if the decoded energy signature matches a stored energy signature, wherein the second transceiver is powered by the WTRU. The one or more antennas and the second transceiver may be configured to receive a second signal from the network.

摘要： Embodiments contemplate techniques for managing aggregation between using an anchor channel over a first frequency band as the anchor band between an Access Point and a wireless receiver/transmitter unit (WTRU). One or more embodiments may include the WRTU receiving one or more beacons via the anchor channel, where the one or more beacons may provide allocation information for allocating a supplementary channel on a second frequency band as a supplementary band that may be different from the first frequency band. Embodiments also contemplate establishing the supplementary channel over the supplementary band using the allocation information provided in the one or more beacons. Embodiments also contemplate exchanging data over the established supplementary channel on the supplementary band.

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.

摘要： A method and apparatus are described for performing channel aggregation to communicate over a non-contiguous spectrum, such as television white space (TVWS), using a plurality of aggregated channels including a primary channel and at least one non-primary channel (e.g., a secondary channel, a tertiary channel or a quaternary channel). Carrier sense multiple access (CSMA) may be performed on the primary channel to obtain access to the primary channel. After waiting an arbitration interframe space (AIFS) and potentially performing backoff on the primary channel, the aggregated channels may be used for transmission. A buffer controller may be used to create, for each of a plurality of access classes (ACs), a logic buffer for each of the channels. A frame controller may be used to provide the buffer controller with aggregated medium access control (MAC) protocol data unit (A-MPDU) frame information, and control aggregation and fragmentation processes.

摘要： Described herein is a silent period method and apparatus for dynamic spectrum management. The methods include configuration and coordination of silent periods across an aggregated channel in a wireless communication system. A silent period management entity (SPME) dynamically determines silent period schedules for channels based on system and device information and assigns a silent period duration and periodicity for each silent period. The SPME may reconfigure the silent period schedule based on system delay, system throughput, channel quality or channel management events. A silent period interpretation entity (SPIE) receives and implements the silent period schedule. The silent periods for the channels may be synchronized, independent, or set-synchronized. Interfaces for communicating between the SPME, SPIE, a channel management function, a medium access control (MAC) quality of service (QoS) entity, a sensing/capabilities database, a MAC layer management entity (MLME) and a wireless receive/transmit unit (WTRU) MLME are described herein.

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. 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.

摘要： Techniques for sending an aggregated beacon in a cognitive wireless network are disclosed. A beacon device may segment beacon information and send beacon segments via a plurality of channels simultaneously. A certain information elements of the beacon information may be included in each beacon segment. Each beacon segment may include channel information for other beacon segments that are transmitted simultaneously. Alternatively, a discovery beacon may be transmitted in addition to a regular beacon. The discovery beacon may include information indicating an operating channel on which the regular beacon is transmitted. The discovery beacon may be transmitted using a predetermined channel bandwidth, with a smaller beacon interval than the regular beacon, or in a frequency hopping fashion. The discovery beacon may be sent on a channel selected based on a regulatory class and corresponding channel information. The discovery beacon may be transmitted on a side channel.
