  • Patent number: 9854473
    Abstract: For use in offloading traffic to a wireless local area network (WLAN) a user equipment (UE) receives from a wireless wide area network at least a first set of thresholds having different thresholds corresponding to different types of data to be offloaded. The UE utilizes the threshold corresponding to a given type of data to evaluate whether an access node operating in the WLAN is suitable for offloading data of the given type. Only if the evaluated access node is determined to be suitable will the UE use it for offloading, and only for data of the given type. In other non-limiting embodiments the first set of thresholds has different thresholds corresponding to different data-types for different categories (e.g., subscription levels) of the UE; and there may be a second set of thresholds with different thresholds corresponding to different classifications of different WLAN access nodes.

    Abstract: There is proposed a mechanism for controlling and conducting a discovery procedure of small cells or secondary ceils located in a macro cell or primary cell. The discovery procedure is based on a discovery signal communicated via PDCH and based on a positioning reference signal (PRS). For configuring the signaling of the discovery signal, frequency domain multiplexing for splitting resources of the PRS in the frequency domain for increasing capacity, and/or usage of reserved communication resources for the signaling of the discovery signal are employed. Assistance information is provided to the UE for supporting the discovery of small cells.

  • Patent number: 9713060
    Abstract: A method, system, and computer program product that provides a two-index system for clusters of small cells in a wireless network. A first index is employed for access to and identification of a serving cell within a cluster of small cells. A second index indicates a group of small cells for determining mobility control. The first index may be derived from primary/secondary synchronization signals, or from frequency/time division multiplex signal position. The second index may be indicated in system/master information block signals or predefined as a plurality of small cells identified by the first index for each cell. Determination of physical cell identification is aided by providing a plurality of primary/secondary synchronization (PSS/SSS) signal alternating configurations with indicator, wherein a maximum number of configurations is predefined.

  • Patent number: 9603025
    Abstract: A method for synchronizing channels on unlicensed bands is described. The method includes determining whether a SCC channel has started to be used by a first network. The SCC channel is a CA channel shared with at least one other network. In response to determining that the SCC channel has been started to be used by the first network, the UE determines an off duration describing a period since a previous SCC channel ON period. A given channel ON period is a continuous period of use of the given channel by the first network, The method also includes, in response to determining that the off duration is less than a minimum threshold duration, performing fine synchronization based on CRS tracking on the SCC channel using course synchronization parameters of the previous SCC channel ON period. Apparatus and computer readable media are also described.
