    Abstract: Devices and methods of enhancing narrowband communications are generally described. NPSS and NSSS are modulated to include an additional bit that indicates a duplexing scheme, a raster frequency offset (zero or non-zero), an operating mode (in-band or standalone/guard-band) or frame timing used by the eNB. The NPSS modulation uses conjugate ZC sequences multiplied by a cover code for each OFDM symbol. The NMIB may provide additional information related to the operating mode or offset. NSSS cyclic shifts may be used to indicate the offset or TDD/FDD use, as may relative locations of the NPSS and NSSS. The NSSS may use symbol-level modulation and time domain cyclic shifts to indicate the frame timing.

    Abstract: Disclosed herein are apparatuses, systems, and methods for reference signal design for initial acquisition, by receiving a first primary synchronization signal (PSS) and a first secondary synchronization signal (SSS) from a first transmit (Tx) beam, in first contiguous orthogonal frequency division multiplexing (OFDM) symbols of a downlink subframe. A UE can receive at least a second PSS and a second SSS from a second Tx beam in contiguous OFDM symbols of the downlink subframe. A UE can then detect beamforming reference signals (BRSs) corresponding to the first Tx beam and the second Tx beam, based on identification of physical cell ID information and timing information processed from the first PSS, the second PSS, the first SSS, and the second SSS. The UE can select the first Tx beam or the second Tx beam that was received with the highest power, based on the BRSs. Other embodiments are described.

    Abstract: Embodiments described herein include user equipment (UE), evolved node B (eNB), methods, and systems for narrowband Internet-of-Things (IoT) communications. Some embodiments particularly relate to control channel communications between UE and eNB in narrowband IoT communications. In one embodiment, a UE blind decodes a first control transmission from an evolved node B (eNB) by processing a first physical resource block comprising all subcarriers of the transmission bandwidth and all orthogonal frequency division multiplexed symbols of a first subframe to determine the first control transmission. In various further embodiments, various resource groupings of resource elements are used as part of the control communications.
