Abstract: A user equipment (UE) in idle mode may use a preconfigured uplink resource for transmission, retransmission, and/or hybrid automatic repeat request (HARQ). For example, the UE may store configuration data for a preconfigured uplink resource and a radio network temporary identifier (RNTI) for idle mode communication. In idle mode, the UE generates an uplink transmission using the preconfigured uplink resource. After the uplink transmission, the UE starts a retransmission timer, and monitors physical downlink control channel (PDCCH) with the RNTI provided in the configuration data for HARQ acknowledgement/negative acknowledgement (ACK/NACK).

Abstract: Systems and methods of providing location techniques for a NB UE are described. The UE transmits, lo a location server, a capability message that indicates position capabilities of the UE to support different positioning methods and common information related to the position methods, including that the UE is a NB UE. The UE receives a request for location information that includes a request for positioning measurements for a particular positioning method, a NB message size limit that indicates a limit on an amount of location information to return, and a NB response time to provide the positioning measurements. At least one of the response time or message size limit is different than for the NB UE than for non-NB UEs. The UE enters an idle state, performs the measurements, and transmits at expiry of or before the NB response time, a message containing the measurements.

Abstract: Methods, systems, and storage media are provided for user equipment (UE) that supports enhanced coverage and may operate with a voice centric usage setting or a data centric usage setting. When the UE's usage setting is set to voice centric, the UE may not operate in coverage enhancement (CE) mode B. When the UE's usage setting is set to data centric, then the UE may operate in CE mode B. The UE may indicate the UE's usage setting in an Attach or Tracking Area Update (TAU) request message, and a mobility management entity (MME) may indicate to an evolved NodeB that CE mode B is restricted or not restricted based on the usage setting. Other embodiments may be described and/or claimed.

Abstract: Embodiments of a next generation Node-B (gNB), User Equipment (UE) and methods for communication are generally described herein. A gNB may be configurable to operate as a master gNB (MgNB). The MgNB may transmit radio-resource control (RRC) signaling to provide information for dual connectivity to allow the UE to utilize radio resources of both a master cell group (MCG) associated with the MgNB and a secondary cell group (SCG) associated with a secondary gNB (SgNB). The MgNB may transmit, to the SgNB, an SgNB release request message that indicates a partial suspension of the dual connectivity, wherein: a first portion of a configuration for the SCG is to be maintained and a second portion of the configuration for the SCG is to be released.

Abstract: This disclosure relates to implementations to support non-UE-specific (i.e. common) and UE-specific search spaces (SS) for M-PDCCH. One implementation relates to a UE comprising RF circuitry to receive, from an eNB, configuration information of one or a plurality of common Search Spaces (CSSs) for M-PDCCH; and baseband circuitry to monitor the one or more configured CSS for M-PDCCH transmissions; wherein the RF circuitry and/or baseband circuitry is adapted to support a reduced bandwidth (BW). Another implementation relates to an eNB comprising RF circuitry to transmit configuration information of a plurality of CSSs for M-PDCCH to one or more UEs supporting a reduced BW, wherein the plurality of CSSs for M-PDCCH are differentiated by “based on functionality”-differentiation that includes the type of use case and/or an EC level of the UE.

Abstract: A Next Generation Node-B (gNB) and methods of communication are generally described herein. The gNB is configurable to operate as a source gNB. The gNB is configured with logical nodes including a gNB central unit (gNB-CU) and a gNB distributed unit (gNB-DU). The gNB-CU comprises a gNB-CU control plane (gNB-CU-CP) for control-plane functionality, and a gNB-CU user plane (gNB-CU-UP) for user-plane functionality. When a handover of a User Equipment (UE) from the source gNB to a target gNB is performed, the gNB transfers, from the gNB-DU to the gNB-CU-UP, a downlink data delivery status (DDDS) message to indicate that the gNB-CU-UP is to stop transfer, to the gNB-DU, of downlink data intended for the UE.

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.
