    Abstract: Discontinuous reception (DRX) alignment techniques for dual-connectivity architectures are described. In one embodiment, for example, user equipment (UE) may comprise one or more radio frequency (RF) transceivers, one or more RF antennas, and logic, at least a portion of which is in hardware, the logic to receive a radio resource control (RRC) configuration information message containing a small cell RRC configuration information element (IE), the small cell RRC configuration IE to contain a small cell discontinuous reception (DRX) configuration IE comprising one or more inter-cell-coordinated small cell DRX parameters, the logic to determine a start time for a small cell DRX cycle based on at least one of the one or more inter-cell-coordinated small cell DRX parameters and initiate the small cell DRX cycle at the determined start time. Other embodiments are described and claimed.

    Abstract: Embodiments of User Equipment (UE) and methods for fast handover failure recovery in a 3GPP LTE network are generally described herein. In some embodiments, the UE may initiate handover (HO) failure recovery by transmission of a random-access channel (RACH) 2 message when both a radio-link failure (RLF) timer and a time-to trigger (TTT) timer are concurrently running. The RACH 2 message may be a message transmitted on a random-access channel for radio-resource control (RRC) connection re-establishment. The RLF timer may be activated as part of a radio-link monitoring (RLM) process based on radio-link conditions with a serving cell, and the TTT timer may have been activated as part of a HO process based on a measurement reporting event.

    Abstract translation: 用户设备（UE）的实施例以及3GPP LTE网络中快速切换故障恢复的方法一般在此描述。 在一些实施例中，当无线电链路故障（RLF）定时器和时间触发（TTT）定时器同时兼容时，UE可以通过发送随机接入信道（RACH）2消息来发起切换（HO）故障恢复 跑步 RACH 2消息可以是在用于无线资源控制（RRC）连接重建的随机接入信道上发送的消息。 基于与服务小区的无线电链路状况，可以将RLF定时器激活为无线电链路监视（RLM）过程的一部分，并且可以基于测量报告事件将TTT定时器激活为HO进程的一部分。

    Abstract: Embodiments described herein relate generally to a communication between a user equipment (“UE”) and a plurality of evolved Node Bs (“eNBs”). A UE may be adapted to operate in a dual connected mode on respective wireless cells provided by first and second eNBs. The UE may be adapted to estimate respective power headroom (“PHR”) values associated with simultaneous operation on the first and second wireless cells. The UE may cause the first and second PHR estimates to be transmitted to both the first and second eNBs. The first and second eNBs may use these estimates to compute respective uplink transmission powers for the UE. Other embodiments may be described and/or claimed.
