    Abstract: Systems and methods for improved inter-frequency measurement are disclosed herein. User equipment (UE) may be configured to communicatively couple to an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB). The eNB may determine a measurement pattern indicating when the UE should perform inter-frequency measurements. The measurement pattern may be selected such that the UE performs measurements more often than once per measurement cycle. The measurement pattern may be selected to balance timing requirements for the UE with increased power consumption that may result from more frequent measurements. The eNB may determine the measurement pattern based on an estimate of UE speed and a number of frequencies to be monitored. A default pattern may be used if the UE speed and/or number of frequencies do not exceed predetermined thresholds.

    Abstract: Technology for performing device-to-device (D2D) communications is disclosed. A user equipment (UE) can identify D2D data to be transmitted from the UE. The D2D data can be identified when the UE is in a radio resource control (RRC) idle. The UE can be limited to using a defined resource allocation mode to transmit the D2D data from the UE. A service request procedure can be initiated at the UE. The service request procedure can trigger the UE to perform an RRC connection establishment procedure with an evolved node B (eNB) to switch the UE from the RRC idle mode to an RRC connected mode. The UE can receive an uplink (UL) grant from the eNB for communicating the D2D data from the UE. The UE can send the D2D data using the UL grant provided by the eNB.

    Abstract: Embodiments of a User Equipment (UE) to operate in accordance with a physical random access channel (PRACH) are disclosed herein. The UE may comprise hardware processing circuitry to determine a coverage enhancement category for the UE based on downlink channel statistics related to reception of downlink signals at the UE from an Evolved Node-B (eNB) and an uplink-downlink imbalance parameter related to uplink reception at the eNB. The hardware processing circuitry may be further to select, for use in a coverage enhancement mode, a PRACH preamble from a set of candidate PRACH preambles based on the determined coverage enhancement category for the UE. In some embodiments, at least some of the candidate PRACH preambles may span a different number of sub-frames.

    Abstract: The techniques introduced here provide for device discovery of a greater number of mobile devices in a mobile network by increasing the multiplexing capacity of the system. The techniques may be applied to device-to-device communication networks and small cells using low power nodes (e.g., pico and femto eNodeB in a 3GPP LTE or LTE advanced network). Additionally, the techniques provide for mapping between a mobile device ID and an orthogonal resource of the discovery signal.
