Abstract: An eNodeB (eNB) and user equipment (UE) are provided that detect whether the UE is in coverage enhancement mode and if so uses a modified version of the Radio Link Control (RLC) configuration in communications between the eNB and UE. Detection mechanisms may differ between the eNB and UE and may include direct signaling between the eNB and UE, the ability to receive control signaling only through particular modified signaling procedures, low power of certain received control signals or lack of response to certain control signals within various predetermined time periods. The modified RLC configuration permits a smaller amount of data than a standard RLC configuration to be transmitted by a transmitting device before a receiving device is able to be polled for information regarding reception by the receiving device of the transmitted data.

Abstract: A device, method and system of handling in-device coexistence (IDC) interference in a wireless network, may comprise detecting the IDC interference between a first communication module operating over a first protocol and a second communication module operating over a second protocol; generating an IDC indication having a bit string comprising four bits, wherein the four bits correspond to a subframe pattern comprising four subframes, a value of a bit of the bit string indicates whether an enhanced node B (eNB) is requested to abstain from using a subframe of the four subframes of the subframe pattern; and transmit the IDC indication to the eNB via a wireless network.

Abstract: In embodiments, apparatuses, methods, and storage media may be described for identifying, by a master evolved NodeB (MeNB), one or more packet data convergence protocol (PDCP) packets that were previously scheduled to be transmitted to a user equipment (UE) by a secondary eNB (SeNB). The PDCP packets that are identified by the MeNB may then be transmitted, or retransmitted, to the UE. Additionally, embodiments may include apparatuses, methods, and storage media for allowing the UE to identify one or more parameters related to a PDCP reordering process to be performed by the UE. Other embodiments may be claimed.

Abstract: Systems, apparatus, user equipment (UE), evolved node B (eNB), and methods are described for generating an extended power headroom report (ePHR) based on an uncertainty associated with a physical downlink control channel communication granting an uplink grant for a physical uplink shared channel communication when the system is configured for simultaneous physical uplink shared channel and physical uplink control channel communications. Some embodiments are structured to generate the ePHR using a type 2 report regardless of the uncertainty associated with the ePHR, while other embodiments generate the ePHR using a reference format. In some embodiments, a UE communicates a timing field with a UE capability communication indicating whether the UE meets timing requirements to avoid uncertainty in ePHR communications.

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.

Abstract: User Equipment (UE), computer readable media, and methods to modify communication channel measurement timing based on a mobility of the UE are disclosed. The UE may include circuitry configured to determine a plurality of signals from one or more cells, determine a first value for a first performance metric associated with a first cell of the one or more cells, wherein the first value is determined from a first measurement, select the first cell for a first communication based on the first value, determine first location information associated with the UE, determine, following the first measurement and using the first location information, that the UE is stationary, and delay, in response to the determination that the UE is stationary, a second measurement of the first performance metric. In various alternate embodiments, different measurement types may be used for mobility and channel quality determinations. In further embodiments, only measurements for unused channels may be delayed.

Abstract: Embodiments of the present disclosure describe systems, devices and methods for system information acquisition in radio resource connection (RRC) connection reestablishment when Radio Link Failure (RLF) happens. Various embodiments may include a serving cell that provides system information of a neighbor cell to a user equipment (UE). When the UE detects an RLF event, the UE may determine whether the previously received system information is valid and proceed with RRC connection reestablishment based on the determination. Other embodiments may be described or claimed.

Abstract: Embodiments of a base station and method for early handover using uplink channel characteristics in a wireless network are generally described herein. In some embodiments, a method for handover determination is performed by an enhanced node B (eNB) operating as a serving cell base station. In these embodiments, a handover decision is based on a signal level of uplink transmissions of user equipment (UE) measured at a target cell base station in addition to signal levels of downlink signals of the target cell base station and downlink signals of a serving cell base station measured at the UE.

Abstract: Methods, systems, and devices for mobility state estimation in a heterogeneous network are disclosed herein. User equipment (UE) includes circuitry to perform a mobility state estimation (MSE) operation to determine an MSE state for the UE, and a receiver to receive, from a cell in a heterogeneous third generation partnership project (3GPP) network, mobility state information corresponding to movement of the UE within the heterogeneous 3GPP network. The circuitry is configured to update the MSE state based on the mobility state information received from the cell. The UE may also include a transmitter to communicate the updated MSE state to the cell.
