    Abstract: The present disclosure provides a mechanism that may allow a UE to determine whether PBCH repetition is enabled in the target cell without performing a hypothesis test. For example, the apparatus may receive a handover message from a serving cell. In an aspect, the handover message may be associated with a handover procedure to a target cell. In addition, the apparatus may determine whether to perform a hypothesis test to determine if a PBCH repetition is enabled in the target cell based on the handover message. In one example, the apparatus may determine not to perform the hypothesis test when the handover message includes information that indicates if the PBCH repetition is enabled in the target cell. In another example, the apparatus may determine to perform the hypothesis test when the handover message does not include information that indicates if the PBCH repetition is enabled in the target cell.

    Abstract: A UE in an eDRX cycle may miss an SI change notification because the UE's receiver may be powered down during the entire modification period prior to the SI change. An apparatus for wireless communication at a base station may transmit SI, change the SI during a period of eDRX by a UE, and transmit the changed SI. The apparatus ensures that a UE receives an SI change notification, even when performing eDRX, by transmitting at least one notification associated with the changed SI after the transmission of the changed SI and during a paging occasion for the UE. In another aspect, an apparatus for wireless communication at a UE enters into an eDRX cycle and receives, after an SI change, a notification associated with the SI change.

    Abstract: Methods, systems, and devices for wireless communication are described. The method includes transmitting a first barring bitmap associated with a first configuration of user equipments (UEs) based at least in part on a decision to implement access class barring (ACB), determining a radio access network (RAN) provides network service to UEs of a second configuration different from the first configuration, transmitting a delay tolerant barring indicator associated with the second configuration based at least in part on the decision to implement ACB and determining that the RAN provides network services to UEs of a second configuration.

    Abstract: Methodologies are described that facilitate inter-eNode B handover. In various embodiments, logical protocol termination can be implemented between the user equipment and the target eNode B for inter-eNode B handover signaling. The provided handover forwarding and encapsulation mechanisms enable improved inter-operability between eNode Bs implementing different protocol versions or from different vendors, which in turn enables frequent protocol upgrades. Additionally, the invention enables the target eNode B to implement new radio configurations even if the configuration is unsupported by the source eNode B.

    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.

    Abstract: Methods, systems, and devices are described for early radio link failure (RLF) declaration. A UE may identify a measurement report message (MRM) trigger and initiate an RLF procedure. In the RLF procedure the UE may determine whether a radio link condition indicative of an RLF has been satisfied before an expiration of a timer that is initiated by the MRM trigger. As an example, the UE may determine that a threshold number of uplink radio link signaling messages, such as MRMs, have been transmitted without a radio link control (RLC) acknowledgement (ACK). The UE may declare RLF based on the determination that the radio link condition has been satisfied. In some examples the UE may verify that channel conditions are better for a target cell than for the serving cell, and may declare RLF based further on the channel comparison.
