Abstract: Embodiments of a User Equipment (UE) and methods for packet based device-to-device (D2D) discovery in an LTE network are generally described herein. In some embodiments, UE may be enabled for proximity services and may be configured to receive signaling from an enhanced node B (eNB) indicating resources allocated for D2D discovery. The UE may configure a discovery packet in accordance with a predetermined configuration to have at least a discovery payload and a cyclic-redundancy check (CRC). The discovery payload may include discovery-related content. The UE may be configured to transmit the discovery packet on at least some of the indicated resources for receipt by a receiving UE. In some embodiments, a demodulation reference signal (DMRS) may be selected to indicate a payload size and/or MCS of the discovery packet's payload.

Abstract: Wireless mobile devices or user equipments (UEs) may communicate directly with other UEs, e.g., using device-to-device (“D2D”) direct discovery and communication. D2D direct discovery and communication may be used, for example, when UEs communicate with each other while within direct wireless range of each other. Different service types for D2D direct discovery and communication sessions, such as public safety (PS) services, non-PS services, etc., may utilize different data characteristics for the discovery message (e.g., data types and data structures). Data associated with the at least one data frame of a D2D direct discovery transmission can be configured to indicate these different data characteristics.

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: Technology for a user equipment, operable to configure a control resource set (CORESET) is disclosed. The UE can decode a signal, received from a next generation node B (gNB), that includes a resource element group (REG) bundling size for a first CORESET. The UE can decode a signal, received from the gNB that includes a REG bundling size for a second CORESET. The UE can decode a control message contained in one or more REGs in one or more of the first CORESET or the second CORESET.

Abstract: Briefly, in accordance with one or more embodiments, an apparatus of a machine-type communication (MTC) user equipment (UE) comprises baseband processing circuitry to establish a radio resource control (RRC) connection with an evolved Node B (eNB), and process a message from the eNB indicating a number of repetitions of physical uplink control channel (PUCCH) transmissions to be used over multiple uplink subframes after the radio resource control connection is established.

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: Systems, methods, and apparatuses can provide or obtain scheduling information for a system information block type1-bandwidth reduced (SIB1-BR) without obtaining a master information block during handover. A user equipment (UE) can identify SIB1-BR scheduling information in a radio resource control connection (RRC) reconfiguration message. The UE can determine scheduling of an SIB1-BR for a target cell based on the RRC reconfiguration message, and process the SIB1-BR received from the target cell during the determined scheduling.

Abstract: A scrambling sequence generation method is disclosed for reference signals, data, and downlink and uplink control channels. The scrambling sequence generation method determines an initial seed value used to calculate the scrambling sequence. The initial seed value is based on different parameters relating to the to be transmitted signals, and some of these parameters are explicitly defined for New Radio.
