    Abstract: User equipment (UE), an enhanced NodeB (eNB) and method of reducing handover latency are generally described. The UE may transmit measurement feedback to the eNB based on control signals. The UE may receive a reconfiguration message from the eNB or another eNB to the UE is attached. The reconfiguration message may contain reconfiguration information indicating whether or not a physical layer or layer 2 of the UE is to be reconfigured and/or a security key is to be updated. The reconfiguration information may be dependent on whether the handover is between eNBs controlled by a same entity and/or whether the handover comprises an intra-frequency transition. The UE or eNB may initiate handover of the UE. During handover the UE may avoid physical layer or layer 2 reconfiguration or the security key update. The security key and data for the UE may be provided directly between the eNBs.

    Abstract: Embodiments of a User Equipment (UE) to support inter-frequency handover are disclosed herein. The UE may receive, from an Evolved Node-B (eNB), a measurement report configuration message that includes multiple measurement events to be determined at the UE. The UE may transmit a measurement report when a combined measurement event occurs. The combined measurement event may include a combination of the multiple measurement events according to a “logical AND” operator such that the combined measurement event occurs when the multiple measurement events occur. The measurement events may be related to signal measurements performed on one or more signals received at the UE from one or more cells configured for operation in the network.

    Abstract translation: 这里公开了用于支持频率间切换的用户设备(UE)的实施例。 UE可以从演进节点B(eNB)接收包括要在UE处确定的多个测量事件的测量报告配置消息。 当组合的测量事件发生时,UE可以发送测量报告。 组合的测量事件可以包括根据“逻辑与”运算符的多个测量事件的组合,使得当发生多个测量事件时发生组合的测量事件。 测量事件可以与对于在配置用于在网络中操作的一个或多个小区在UE处接收的一个或多个信号执行的信号测量有关。

    Abstract: Embodiments of the present disclosure are directed towards devices and methods for discovering and waking up dormant access nodes in cellular networks. In one embodiment, the dormant access nodes passively participate in a device-to-device discovery process to identify potential user equipment nearby. Upon identifying a potential user equipment, the dormant access node may wake itself up and inform a serving access node that that is able to service the user equipment. In another embodiment, dormant access nodes may transmit a discovery message periodically. Upon receiving the discovery message a user equipment may report the availability of the dormant access node to its serving access node.
