    Abstract: Certain aspects of the present disclosure relate to reporting difference in timing between cells using multiple connectivity in a wireless network. A first connection served by at least a first cell and a second connection served by at least a second cell to facilitate communicating with at least the first cell and at least the second cell are established. A reporting configuration specifying one or more parameters related to reporting a timing difference between cells is received. A timing difference between at least the first cell and at least the second cell is determined, and the timing difference is reported to at least the first cell over the first connection or to at least the second cell over the second connection. This can facilitate scheduling time aligned operations over the first and second cells, or related cell groups, in multiple connectivity.

    Abstract: Aspects of the present disclosure provide techniques that may be used wireless network communication devices to support devices operating with extended discontinuous reception (eDRX). An exemplary method, performed by a BS, generally includes determining at least one paging hyper-frame for paging a user equipment (UE) based on an identification (ID) of the UE, the paging hyper-frame determined from a set of periodically occurring hyper-frames that each span a number of radio frames, receiving a request to page the UE, and transmitting a paging signal to the UE in at least one subframe within a radio frame of the paging hyper-frame. Another exemplary method, performed by a UE, generally includes determining at least one paging hyper-frame for monitoring for a paging signal from a base station (BS) based on an identification (ID) of the UE, the paging hyper-frame determined from a set of periodically occurring hyper-frames that each span a number of radio frames, and monitoring for the paging signal in at least one subframe within a radio frame of the paging hyper-frame.

    Abstract: Techniques are provided for adaptively changing a periodicity of measuring signal characteristics for a UE in a relatively high speed environment based on one or more signal characteristics being outside of a threshold. Periodicity of measuring signal characteristics may be made directly by changing an interval at which measurements are taken. In certain examples, periodicity of measuring signal characteristics may be made indirectly by changing the length of a discontinuous reception (DRX) cycle. Some techniques provide one or more radio link monitoring (RLM) parameters may be modified based on a determination that a UE is in a high speed environment or measured signal characteristics are outside of a threshold.

    Abstract: In a wireless communication system, user equipment (UE) has autonomy provided by one or more set of rules to handle processing during a measurement gap. UE can ignore or use only a portion of the whole measurement gap if not needed. Thereby, an urgent need for remaining tuned to source carrier frequency can be supported, such as utilizing Random Access Channel (RACH) procedure. UE can also choose to tune to a target carrier frequency supporting timely handovers. Depending on the type of processing required (download shared channel (DL-SCH, UL-SCH, TTI bundling, RACH or SR), the UE may store requests and process the measurements during the gap or ignore the gap measurement as if there were no gaps.

    Abstract: Methods, systems, and devices for radio resource management (RRM) measurement and reporting for license assisted access (LAA) cells operating in unlicensed or shared frequency spectrum are described. A user equipment (UE) may receive an RRM measurement configuration including a channel occupancy parameter for measuring neighbor cells of a shared frequency band. The channel occupancy parameter may be used to determine a channel occupancy metric that may be sent to a base station for cell selection. The channel occupancy metric may include an averaged or filtered received signal strength and may be reported for serving cells and/or intra-frequency neighbor cells. A base station may further configure a UE with a discovery reference signals (DRS) measurement timing configuration (DMTC), which may include an extended DMTC search window. The UE may search for DRS transmissions from neighbor cells according to the DMTC.
