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 catergories (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: 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.

Abstract: A network controlling entity in a heterogeneous or local area network (such as a macro eNB) selects a set of network access nodes that share a common wake-up area code WUAC. The network controlling entity selects a transmission entity such as a motile terminal/UE and directs it to wirelessly transmit a signal on a given radio resource. The network controlling entity also informs each network access node within the set of the given radio resource on which they should listen for the signal. In various embodiments the network access nodes within the set can choose whether or not to listen for the signal and thus choose whether they will wakeup, or they can reply to the signal with a request for wakeup confirmation. In this manner WUAC-specific sets of small cells can be awakened only when needed for traffic offloading and thereby saving energy.

Abstract: Methods, apparatus and computer program products configure a sounding reference signal (SRS) for a segment carrier that serves as a contiguous bandwidth extension of a component carrier, such as a component carrier that is backwards compatible with prior releases of a mobile terminal. In the context of a mobile terminal, the method receives a triggering message that identifies respective configurations of the SRS for the component carrier and the associated segment carrier. The configuration of the SRS for the component carrier is different than the configuration of the SRS for the segment carrier. The method also causes the SRS to be transmitted in accordance with the respective configurations identified by the triggering message via uplink subframes of the component carrier and the segment carrier.
