Abstract: 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.

Abstract: 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.

Abstract: Systems, methods, and apparatus may be used to provide assistance for connection procedures in a hierarchical network where macro cells may be operating in licensed spectrum while small cells may be operating in dynamic and shared spectrums, such as TVWS. This may be done, for example, to allow an LTE system performing carrier aggregation (CA) to reconfigure itself to change from a supplementary cell (SuppCell) in one dynamic and shared spectrum channel to a SuppCell in another dynamic and shared spectrum channel.

Abstract: Methods, apparatus and systems for managing an exposure of a network to a wireless transmit/receive unit (WTRU) are disclosed. One representative method includes receiving, by an access point (AP) of the network, information associated with the WTRU; and selectively exposing, by the AP, the network.

Abstract: Methods and apparatus are described. According to a method, a wireless transmit/receive unit (WTRU) communicates with a base station using a first base station operating frequency and a set of cell configuration parameters. The WTRU receives information indicating a second base station operating frequency to use for communications with the base station at a given time. The WTRU communicates with the base station using the second base station operating frequency and the same set of cell configuration parameters on or after the given time.

Abstract: An access point includes a transmitter configured to transmit signals, a receiver configured to receive signals, and a timing information device. The timing information device is configured to receive a timing information request from a station associated to the access point, receive timing information for a beacon signal sent by a second access point, and report the timing information to the station. The timing information includes a time difference relative to a known reference time for transmission of the beacon signal and the time difference is an offset in timing units.

Abstract: 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.
