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.

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： Systems and methods for dynamic white space management are described. First, local handling of channel queries, in which a channel query by a white space device (WSD) is handled by a local dynamic spectrum management (DSM) server, if the DSM server has all the information necessary for providing a response to the channel query. Second, a search extension, in which a WSDB passes part of a search for available channels to a local DSM server. Third, assisting of an available channel calculation, in which a DSM server provides spectrum sensing information to WSDBs to improve the available channel calculation within the WSDBs. And fourth, dynamic bandwidth management to meet the coexistence requirements. In addition, the content of the messages and procedures that enable the above value-adding functions and interactions with the WSDB systems are described.

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 method and apparatus for a secondary wireless transmit/receive unit (WTRU) to use of secondary cellular spectrum are provided. The secondary WTRU monitors transmissions of a primary WTRU; determines whether to provide assistance to the primary WTRU; and in response to a determination to provide assistance, performs cooperative communications with the primary WTRU for its transmission of data to a base station. If the assistance results in the data being transmitted to the base station faster than it would have with out assistance, the secondary WTRU may utilize uplink resources originally intended for the primary WTRU.
