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 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.

Abstract: Disclosed herein are apparatuses, systems, and methods using or implementing a control channel (PDCCH) design. The PDCCH can occupy an initial number of OFDM symbols of a downlink subframe, while occupying less than the full system bandwidth. The PDCCH can be time division multiplexed (TDM) with a shared channel (PDSCH) or frequency division multiplexed (FDM) with a PDSCH. The PDCCH can further be multiplexed with another PDCCH in a contiguous or non-contiguous region. Resources allocated to the PDCCH can overlap or partially overlap resources allocated to the PDSCH. An Evolved Node-B (eNB) can provide configuration information for the PDCCH design in Radio Resource Control (RRC) signaling to a user equipment (UE), or through use of a Master Information Block (MIB) or System Information Block (SIB).

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 of an Evolved Node-B (eNB), User Equipment (UE), and methods for flexible duplex communication are generally described herein. The eNB may transmit a downlink control information (DCI) block to the UE during a group of time-division duplex (TDD) sub-frames. The eNB may further receive an uplink control information (UCI) block from the UE during the group of TDD sub-frames. A first candidate flexible duplex format for the TDD sub-frames may include a downlink control portion and an uplink control portion. A second candidate flexible duplex format for the TDD sub-frames may include a downlink control portion and may exclude uplink control portions.
