Abstract: Embodiments of efeMTC synchronization signals for enhanced cell search and enhanced system information acquisition are described. In some embodiments, an apparatus of a base station (BS) is configured to generate a length-x sequence for an efeMTC synchronization signal, the length-x sequence configured for repetition in frequency domain within 6 physical resource blocks (PRB). In some embodiments, to generate the length-x sequence, the BS may be configured to select any one index of the set of root indices {1, 2, 63}, excluding the root indices 25, 29 and 34, to correspond to a different physical-layer cell identity (PCID). In some embodiments, the BS may be configured to encode RRC signaling to include a System Information Block (SIB) comprising configuration information for transmission of the efeMTC synchronization signal, and transmit the length-x sequence as the efeMTC synchronization signal in frequency resources according to the SIB.

Abstract: An apparatus of a Narrowband Internet-of-Things (NB-IoT) user equipment (UE) includes processing circuitry. To configure the NB-IoT UE for open loop transmit power control, the processing circuitry is to decode a narrowband system information block (NB-SIB) to obtain a narrowband physical random access channel (NPRACH) resource set and power control information associated with the NPRACH resource set. A random access channel (RACH) preamble is encoded for transmission with or without repetitions to a base station during a RACH procedure and using the NPRACH resource set. The transmission has transmission power based on the power control information. A narrowband uplink resource assignment received during the RACH procedure is decoded. A connection setup completion message is encoded for transmission to the base station using the narrowband uplink resource assignment.

Abstract: An apparatus of a user equipment (UE) includes processing circuitry configured to decode a master information block (MIB) using a set of physical broadcast channel (PBCH) symbols received within a downlink frame to obtain system frame number (SFN) information. The downlink frame includes multiple copies of the PBCH symbols within at least three subframes of the downlink frame. A system information block (SIB) may be decoded based on the SFN information, to obtain uplink channel configuration information. Random access channel (RACH) procedure may be performed with a base station (BS) based on the uplink channel configuration information, to obtain an uplink resource assignment. A connection setup completion message can be encoded for transmission to the BS using the uplink resource assignment. The set of PBCH symbols can include a set of four legacy PBCH symbols.

Abstract: Embodiments of a user equipment (UE) and method for resource allocation and device-to-device (D2D) discovery hopping are generally described herein. In some embodiments, the UE may receive signaling from an enhanced node B (eNB) indicating discovery resources to transmit discovery signals on within an LTE operation zone. The discovery resources may include a discovery zone which may comprise a plurality of physical resource blocks (PRBs) and a plurality of subframes. The UE may transmit a discovery signal for receipt by one or more other UEs for D2D discovery within some of the PRBs of the discovery zone. The PRBs for the transmission of the discovery signal may be determined in accordance with a hopping mode to provide increased frequency diversity within a bandwidth of the discovery zone. The hopping mode may comprise intra-subframe hopping, inter-subframe hopping or joint intra/inter-subframe hopping.

Abstract: In embodiments, a base station may identify a parameter related to a zero power (ZP) resource element (RE) mapping set in a physical resource block (PRB). The ZP RE mapping set may relate to resources that are not to be used to transmit a physical channel transmission. The base station may then transmit, to a user equipment (UE), an indication of the ZP RE mapping set. Other embodiments may be described and/or claimed.

Abstract: Embodiments of dynamic multiplexing are described, including the transmission of preemption indication (PI) to indicate preemption of time-frequency resources. In some embodiments, a next Generation NodeB (gNB) is configured to transmit PIs in signaling to preempt an enhanced Mobile Broadband (eMBB) communications transmission with an ultra-reliable and low latency communications (URLCC) transmission. In some embodiments, a user equipment (UE) is configured to monitor a region of time-frequency resources, within a bandwidth part (BWP), for a PI. The PI indicates to the UE a portion of time-frequency resources that omit transmissions intended for the UE. In some embodiments, the gNB transmits the PI to the UE within preemption indication downlink control information (PI-DCI) in a physical downlink control channel (PDCCH) in a control resource set (CORESET). In some embodiments, the BWP is defined according to a frequency domain location, a bandwidth, and a subcarrier spacing for a given numerology.

Abstract: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The UE may receive radio resource control (RRC) signaling that configures reception of a plurality of physical downlink shared channels (PDSCHs) in a frame. The frame may comprise multiple slots, including one or more downlink slots and one or more uplink slots. The UE may determine a subset of the PDSCHs, such that for each of the PDSCHs of the subset, corresponding consecutive slots do not overlap the uplink slots. The UE may set a number of bits of a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook equal to a number of PDSCHs in the determined subset.
