Abstract: A technique is disclosed to minimize service interruption at a wireless user equipment device during a handover by maintaining dual active connections during the handover. Upon initiating the handover, an initial/first connection with a first access node is maintained while establishing a second connection with a second access node. The user equipment device can receive data over the first connection and second connection during the handover. The first connection may be terminated (by the user equipment device or by timing out due to inactivity) after the handover is completed. Other aspects, embodiments, and features are also claimed and described.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for caching content at a network edge and providing the cached content to requesting UEs. An example method generally includes receiving, from a first UE, a request for content from a remote source, retrieving the content from the remote source and providing the content to the first UE, storing at least a portion of the content in a local cache at the base station, receiving a request for the content from at least a second UE, and retrieving the content from the local cache and providing the content to the at least the second UE.

Abstract: Methods and apparatus for improving Circuit Switched (CS) Fallback performance, such as in an LTE network, are described. In one aspect, a UE may perform a RAU procedure before performing a CS call setup procedure when the UE has camped on a Non-DTM GERAN target after failing to access a redirection target. In another aspect, an MME may determine whether to perform a PS suspension based on an ISR status associated with a user terminal. In another aspect, an eNB may send information associated with a PS suspension to a user terminal.

Abstract translation: 描述了用于改善电路交换（CS）后退性能的方法和装置，例如在LTE网络中。 在一个方面，当UE在不能访问重定向目标之后，当UE驻留在非DTM GERAN目标上时，UE可以在执行CS呼叫建立过程之前执行RAU过程。 另一方面，MME可以基于与用户终端相关联的ISR状态来确定是否执行PS暂停。 在另一方面，eNB可以向用户终端发送与PS暂停相关联的信息。

Abstract: Methods, systems, and devices are described for discontinuous transmission and/or discontinuous reception in time division duplex (TDD) systems that may have data transmission formats dynamically reconfigured. An initial uplink-downlink (UL-DL) configuration for TDD communication between an eNB and user equipment (UE) may be established. This initial UL-DL configuration may be reconfigured to a different UL-DL configuration for one or more UEs in communication with the eNB. When a UE switches to discontinuous reception (DRX) mode, it may monitor control information from the eNB during DRX on periods, a frequency of the DRX on periods based on a reference UL-DL configuration irrespective of any reconfiguration of UL-DL configuration for a particular UE. In some aspects, a UE that is operating in a UL-DL reconfiguration mode may, upon entering DRX mode, autonomously discontinue operating in the UL-DL re-configuration mode.
