Abstract: An apparatus and system to enable URLLC PUSCH repetitions in the unlicensed spectrum are described. The number of consecutive PUSCH repetitions indicated in the RRC parameter is reinterpreted as the number of transmission occasions over which the UE is able to attempt CCA. An orphan symbol is used to provide a DMRS transmission or cyclic prefix of the PUSCH transmission causing the orphan symbol. Whether a CG-UCI is piggybacked in a PUSCH transmission, and whether DCI-DFI is used, is dependent on whether cg-RetransmissionTimer is configured.

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.

Abstract: Embodiments of a User Equipment (UE) and methods of communication are generally described herein. If the UE is configured by higher layers to transmit, in a set of symbols of a slot, a sounding reference signal (SRS), a physical uplink control channel (PUCCH), a physical uplink shared channel (PUSCH), or a physical random access channel (PRACH); and if a downlink control information (DCI) format indicates that the UE is to receive, in a subset of the set of symbols of the slot, channel state information reference signals (CSI-RS) or a physical downlink shared channel (PDSCH): the UE may: cancel transmission of the PUCCH, the PUSCH, or the PRACH in remaining symbols from the set of symbols; and may cancel transmission of the SRS in remaining symbols from the subset of symbols.

Abstract: An enhanced NodeB (eNB), user equipment (UE) and method of Channel State Information (CSI) measurement and reporting using reduced bandwidth are generally described herein. The UE is preconfigured with a resource configuration information or the configuration information is transmitted to the UE from the eNB. The configuration information indicates a narrowband region on which to monitor for and receive physical downlink control and data channels and perform measurements for CSI computation. The region has a reduced bandwidth that is supported by the UE and is free from subbands outside of the region. The UE takes measurements of downlink transmissions using the assigned resources. The measurements are limited to subbands included within the region. The UE calculates the CSI based on an unrestricted time interval within subframes of the region and a restricted frequency interval free from physical resource blocks outside the region. The UE reports a region-specific wideband CSI that includes at least a region-specific wideband Channel Quality Indicator to the eNB.

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.

Abstract: Embodiments described herein relate generally to a device that is to transmit signals using a control channel. The device may be, for example, a user equipment or low-powered radio access node. Before transmitting the signal, the transmitting device may modify symbols associated with the signal. For example, the transmitting device may generate a scrambling sequence and modulate the symbols associated with the signal with the scrambling sequence. In another example, the transmitting device may apply a shifting pattern or hopping pattern to the sequence indices associated with sequences for symbols to be included in the signal. The applied pattern may change one or more sequence indices associated with one or more symbol indices associated with the signal. Other embodiments may be described and claimed.
