Abstract: Devices for and methods of synchronous beam refinement using a beam refinement reference signal (BRRS) are generally described. In one example embodiment, a UE receives BRRS information indicating switching of a Tx beam. The UE then uses this information to switch an associated Rx beam. In some embodiments, timing information is used to match the switching times. In some embodiments. DCI and CSI-RS operations are used to determine switching for the synchronous beam refinement.

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: Embodiments of a User Equipment (UE), an Evolved Node-B (eNB), and methods for communication of uplink messages are generally described herein. The UE may receive, from an eNB, one or more downlink control messages that may indicate an allocation of PUCCH channel resources. The UE may transmit an uplink control message in at least a portion of the allocated PUCCH channel resources. When the PUCCH channel resources are allocated according to an edge configuration, the PUCCH channel resources may be restricted to a lower edge portion and an upper edge portion of the network channel resources. When the PUCCH channel resources are allocated according to a distributed configuration, the PUCCH channel resources may include one or more middle portions of the network channel resources. The middle portions may be exclusive to the lower edge and upper edge portions.

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: Embodiments of a Generation Node-B (gNB) and methods of communication are disclosed herein. The gNB may be configured with logical nodes including a gNB central unit (gNB-CU) and a gNB distributed unit (gNB-DU). The gNB-CU 106 may determine a first precoding matrix and a second precoding matrix for a precoding of one or more data streams for transmission on a plurality of antennas coupled to the gNB-DU. The precoding may be in accordance with a split functionality between the gNB-CU and the gNB-DU that includes: precoding by the gNB-CU with the first precoding matrix, and precoding by the gNB-DU with the second precoding matrix.
