Abstract: Technology for a user equipment (UE) operable for MulteFire (MF) narrowband (NB) internet of things (IoT) is disclosed. The apparatus can comprise one or more processors configured to: decode a special subframe from a data segment carried on an nframe that is transmitted in a data channel; identify a downlink pilot time slot (DwPTS) and a guard period (GP) from the special subframe; and switch from receiving in the data channel to transmitting in the data channel during a duration of the special subframe.

Abstract: The present disclosure provides apparatuses, systems, methods, and machine readable storage medium for communications in a Narrow Band Internet of Things (NB-IoT) system in a sub-1 GHz band. In an embodiment, an apparatus for a user equipment (UE) includes a memory interface and a processor. The memory interface is operable to receive a configuration of a frame from a memory, the frame is to be used for communications in a Narrow Band Internet of Things (NB-IoT) system in a sub-1 GHz band, wherein the frame includes one or more anchor channels and one or more data channels. The processor is operable to encode uplink (UL) communication data for a base station or decode downlink (DL) communication data from the base station based on the configuration of the frame.

Abstract: Systems and methods of measuring reference signals in a multefire scenario are described. A UE receives control information anchor channel dependent on whether the UE is in an adaptive frequency hopping system (FHS) and whether the FHS is a LBT FHS. The reference signals are received on an unlicensed band via the anchor and/or a non-anchor channel and measured for RRM and/or in-sync or out-of-sync measurements. RRM measurements are transmitted to the eNB for mobility management and otherwise the validity of an in- or out-of-sync indication is determined and a counter started when valid. The control information has a subframe configuration and resource allocation, which is used for SRS transmission on the non-anchor channel. Uplink scheduling information is received on the anchor channel for data transmission on the non-anchor channel based on the SRS.

Abstract: Technology for a Next Generation NodeB (gNB) operable to communicate over an anchor channel for Unlicensed Internet of Things (U-IoT) is disclosed. The gNB can encode control information for periodic transmission on a set frequency of an anchor channel for U-IoT in an adaptive frequency hopping system. The anchor channel can include a clear channel assessment (CCA) period, an extended CCA (eCCA) period when a failure occurs during the CCA period, a tuning period for radio frequency (RF) retuning with frequency hopping, and a control information communication period for communication of the control information.

Abstract: Described is an apparatus of a User Equipment (UE). The apparatus may comprise a first circuitry and a second circuitry. The first circuitry may be operable to process a first Downlink Control Information (DCI) format 0A transmission indicating a semi-persistent scheduling (SPS) activation. The first circuitry may also be operable to process a second DCI format 0A transmission indicating an SPS release. The second circuitry may be operable to generate one or more Uplink (UL) transmissions for an unlicensed spectrum of the wireless network after the SPS activation and before the SPS release in accordance with a configured schedule.
