Abstract: Embodiments described herein relate generally to techniques for device discovery for device-to-device (D2D) communications. A user equipment (UE) may receive a transmission probability (e.g., from an evolved Node B (eNB)) for transmission of a discovery medium access control (MAC) protocol data unit (PDU) for D2D communications. The UE may determine a pseudo-random number based on an identifier of the UE, information in the discovery MAC PDU, or information associated with a discovery period. The UE may compare the pseudo-random number with the transmission probability to determine whether to transmit the discovery MAC PDU in the discovery period. Another UE may also determine the pseudo-random number to determine whether the UE is to transmit the discovery MAC PDU in the discovery period. Other embodiments may be described and claimed.

Abstract: Embodiments of an enhanced node B (eNB), user equipment (UE) and methods of signaling for proximity services and device-to-device (D2D) discovery in an LTE network are generally described herein. In some embodiments, the eNB may transmit signaling to indicate D2D discovery zone configuration to proximity service (ProSe) enabled UEs. The signaling may indicate time and frequency resources and a periodicity of a discovery zone and may indicate operational parameters for the discovery zone. The resources of the D2D discovery zone may be allocated for D2D discovery signal transmission by the ProSe-enabled UEs.

Abstract: A technology is disclosed for an evolved Node B (eNB) operable to transmit a physical downlink control channel (PDCCH) to a user equipment (UE). The eNB can determine a set of configuration indication fields numbered 1 to N, included in a downlink control information (DCI) format Y carried on the PDCCH, where N = ⌊ L format   Y M ⌋ , Lformat Y is equal to a payload size of the DCI format Y, and M is a number of bits of each configuration indication field. The eNB can map the DCI format Y onto the PDCCH. The eNB can transmit to the UE the PDCCH with a cyclic redundancy check (CRC) scrambled by an enhanced interference mitigation and traffic adaptation (eIMTA) Radio-Network Temporary Identifier (RNTI) for the UE.

Abstract: Techniques for observed time difference of arrival (OTDOA) positioning based on heterogeneous reference signals (RSs) are discussed. One example apparatus configured to be employed within a user equipment (UE) comprises receiver circuitry, a processor, and transmitter circuitry. The receiver circuitry can receive, from each of a plurality of evolved Node Bs (eNBs), one or more RSs of each of a plurality of distinct types of RSs. The processor can determine, for each of the eNBs, a time of arrival (TOA) of the one or more RSs of each of the plurality of distinct types of RSs; and compute, for each of the eNBs, a reference signal time difference (RSTD) based at least in part on the TOAs of the one or more RSs of each of the plurality of distinct types of RSs. The transmitter circuitry can transmit the RSTD computed for each of the eNBs.

Abstract: Technology for dynamically reconfiguring an uplink-downlink (UL-DL) time-division duplexing (TDD) configuration is disclosed. In an example, a user equipment (UE) can have computer circuitry configured to: Receive a UL-DL reconfiguration indicator from a node to dynamically reconfigure a flexible subframe (FlexSF) to a different UL-DL transmission direction from a semi-static UL-DL configuration; apply a DL channel timing based on a DL favored UL-DL configuration; and apply a UL channel timing based on a UL favored UL-DL configuration. The FlexSF can be capable of changing an UL-DL transmission direction. The DL favored UL-DL configuration can include more DL subframes than a semi-static UL-DL TDD configuration for the UE, and the UL favored UL-DL configuration includes more UL subframes than a semi-static UL-DL TDD configuration for the UE.

Abstract: A user equipment (UE) enables synchronous peer-to-peer communication between devices for out of network coverage and partial network coverage scenarios. The UE performs a synchronization procedure and selects a spectrum resource within an uplink (UL) spectrum for device-to-device (D2D) communication. The UE, representing a synchronization source, generates timing information and synchronization signals for synchronizing a group of wireless communication devices (peer UEs) with the UE in a local synchronization area. The UE transmits, in selected or pre-allocated time or frequency resources, a synchronization signal including the timing information in order to synchronize devices in the local synchronization area.

The UE can decode PRS configuration information for one or more cells in the plurality of cells. The UE can determine, for the one or more cells in the plurality of cells, an existence of a CRS for selected subframes of a plurality of subframes based on the MBSFN subframe configuration information. The UE can determine for the one or more cells in the plurality of cells, an existence of a PRS for selected subframes of the plurality of subframes based on the PRS configuration information. The UE can measure the RSTD for the one or more cells in the plurality of cells using the CRS and the PRS.
