摘要： Systems and techniques for link failure management in multiple connection systems. Upon detection of a link failure with a local area base station during a dual connection mode in which the user device is connected to a macro base station and a local area base station, a user device sends a failure indication and a measurement results report for serving and neighboring base stations to its serving macro base station, and selects a response to the failure based at least in part on evaluation information received from the macro base station. Upon detection of a link failure with a macro base station, the user device determines whether to reconnect to the macro base station or a different macro base station and whether to reconnect with the original local area base station or a different local area base station.

摘要： The present invention relates to devices, methods and computer program products concerning a communication link in, for example, a so-called unlicensed band. The invention proposes an apparatus, comprising: a control module configured to control a transceiver being controllable to use at least one of at least two transmission resources for communication with a respective other apparatus, wherein a first transmission resource is useable for a direct communication with another apparatus of a first type and a second transmission resource is useable for a communication with one of plural other apparatuses of a second type each linked to the other apparatus of the first type, determine whether communication is setup via one of the plural other apparatuses of the second type, and, in response thereto, obtain information for deciding to switch the communication to another one of the apparatuses of the second type, evaluate the information obtained, and, cause to decide to switch the communication to one other apparatus of the second type.

摘要： A method, apparatus and computer program product are provided for enabling efficient allocation of discovery resources for device to device communications. An example method may comprise establishing a cellular network connection to an access point. The method may further comprise establishing a local area network connection to a user equipment. Additionally, the method may comprise either receiving offloaded data for the user equipment from the access point via the cellular network connection and relaying the offloaded data to the user equipment via the local area network connection, or receiving offloaded data for the access point from the user equipment via the local area network connection and relaying the offloaded data to the access point via the cellular network connection. Similar and related example methods, example apparatuses, and example computer program products are also provided.

摘要： A method, apparatus, and computer program product are provided to manage the establishment of a dual connection. A method according to an example embodiment may include causing a dual connection setup request message to be transmitted to a local area access point (LAAP) and causing a dual connection command to be transmitted to a user equipment (UE). The method further includes receiving a dual connection establishment complete message and causing resources associated with one or more split bearers to be released or suspended.

摘要： 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. Signaling the PSS/SSS configurations by one of broadcast or dedicated signaling, said signaling indicating whether each configuration is one of periodic or aperiodic alternation.
