Abstract: In one embodiment, an apparatus includes memory storing instructions and processing circuitry coupled to the memory. The processing circuitry is to implement the instructions to select a resource block group (RBG) size configuration from a set of RBG size configurations based on a bandwidth part (BWP) size. Each RBG size configuration is to indicate RBG sizes associated with respective ranges of BWP sizes, and the RBG sizes are to indicate a number of frequency-domain physical resource blocks (PRBs) for physical downlink shared channel (PDSCH) or physical uplink shared channel (PUSCH) transmissions. The processing circuitry is further to implement the instructions to allocate PRBs for communication between the gNB device and a user equipment (UE) device via the PDSCH or PUSCH transmissions based on the selected RBG size, and to encode downlink control information (DCI) that indicates the allocated PRBs for transmission to the UE device.

Abstract: Narrowband Internet of Things synchronization signals are described that carry offset information. In one example an evolved NodeB (eNB) to performs operations to transmit synchronization signals for time and frequency synchronization between the eNB and user equipments (UEs) for narrowband Internet of things (NB-Iot). The operations include concatenating a plurality of short ZadoffChu (ZC) sequences each having a different root index, the ZC sequences being ordered to indicate an offset for use by a UE, generating an NB-Iot Primary Synchronization Signal (NB-PSS) using the concatenation of short ZadoffChu (ZC) sequences, and transmitting the resulting NB-PSS by the eNB in a periodic manner to the UE, wherein, the offset is identified by the order of the ZC sequences.

Abstract: A Narrowband-Internet-of-Things (NB-IoT) device may select between multiple carrier resources (of an anchor carrier and/or non-anchor carriers) to perform a Narrowband Physical Random Access Channel (NPRACH) procedure. The NB-IoT device may determine, based on a reference signal from an enhanced NodeB (eNB), a coverage level for the NB-IoT device and receive carrier configuration information, from the eNB, that indicates the carriers (e.g., an anchor carrier and one or more non-anchor carriers) that are available for NPRACH procedure. The NB-IoT device may select a carrier resource from among the carriers based on factors, such as the coverage level of the NB-IoT device and the Reference Signals Received Power (RSRP) thresholds and Repetition levels of the carrier resources. The NB-IoT device may use the selected carrier resource to initiate the NPRACH procedure.

Abstract: An apparatus configured to be employed in a user equipment (UE) associated with a new radio (NR) system is disclosed. The apparatus comprises a processing circuit configured to determine an NR-physical uplink control channel (PUCCH) resource to be utilized by the UE, for a transmission of a hybrid automatic repeat request (HARQ)-acknowledge (ACK) feedback message to a gNodeB, wherein the determined NR-PUCCH resource comprises a HARQ-PUCCH resource. In some embodiments, the HARQ-ACK feedback message comprises a feedback message generated at the UE in response to processing a downlink (DL) data transmission signal comprising data received from the gNodeB. In some embodiments, the processing circuit is further configured to generate a transmission of the HARQ-ACK feedback message using the determined HARQ-PUCCH resource.

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 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: An eNodeB (eNB), user equipment (UE) and method of providing a quasi-orthogonal multiple access (QOMA) resources are generally described. The UE receives allocation of orthogonal multiple access (OMA) and non-OMA (NOMA) resources. The UE transmits data up to a maximum NOMA rate and NOMA Modulation and Coding Scheme (MCS) using the NOMA resources without receiving an explicit transmission grant from the eNB. The eNB may allocate multiple NOMA regions associated with different maximum rates, MCSs, number of UEs, UE types, applications and sizes. If the data exceeds the NOMA conditions or the UE is unable to transmit data using the allocated NOMA resources or does not receive an acknowledgement from the eNB regarding reception of the transmitted data, the UE may request an explicit grant of the OMA resources from the eNB and, upon receiving an allocation of the OMA resources, subsequently transmit the data using the allocated OMA resources.

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.
