Abstract: Embodiments of a Machine Type Communication User Equipment (MTC UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The MTC UE may determine a system timing based on reception of a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). The MTC UE may receive, from the gNB, radio resource control (RRC) signaling that indicates one or more parameters of a configurable resynchronization signal (RSS). The RSS may be for resynchronization, by the MTC UE, after the MTC UE awakens from a power save mode. The parameters of the RSS in the RRC signaling may depend on a target coverage of the MTC UE. The MTC UE may determine an updated system timing based on reception of the RSS.

Abstract: Technology for a Next Generation NodeB (gNB) operable to communicate a channel state information reference signal (CSI-RS) resource element (RE) mapping configuration to a user equipment (UE) is disclosed. The gNB can determine a CSI-RS RE mapping configuration that 5 identifies resource elements for a CSI-RS resource at a frequency domain location (k) and at a time domain location (l). The gNB can encode the CSI-RS RE mapping configuration for transmission to the UE via higher layer signaling.

Abstract: Described is an apparatus of a User Equipment (UE) operable to communicate with a fifth-generation Evolved Node-B (gNB) on a wireless network. The apparatus may comprise a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to detect a beam failure event. The second circuitry may be operable to generate a beam failure recovery request for transmission to the gNB, in response to the beam failure event. The third circuitry may be operable to monitor for Physical Downlink Control Channel (PDCCH) in a search space configured by the gNB, subsequent to a transmission of the beam failure recovery request.

Abstract: Described is an apparatus of a User Equipment (UE) operable to communicate with an Evolved Node-B (eNB) on a wireless network. The apparatus may comprise a first circuitry and a second circuitry. The first circuitry may be operable to process a Downlink (DL) transmission carrying one or more Phase Tracking Reference Signal (PT-RSes). The second circuitry may be operable to generate an Uplink (UL) transmission carrying a Layer Indicator (LI) based at least on a number of PT-RS Antenna Ports (APs) associated with the PT-RSes.

Abstract: Apparatuses, systems, and methods for multiplexing of PUCCH for beam failure recovery and other signals. A UE may determine a transmission dropping rule and a transmission power scaling rule for a PUCCH which is dedicatedly configured for secondary BFR transmission, such as a PUCCH-BFR, when it is multiplexed with at least one other signal. The PUCCH-BFR and the at least one other signal may be multiplexed in a CC or in multiple CCs. The UE may determine a transmission dropping rule, e.g., so that UE can transmit an uplink signals with higher priority and drop the other uplink signal with lower priority to avoid beam collisions. The UE may determine a transmission power scaling rule, e.g., so the UE may scale transmission power within a CC and/or across CCs. The UE may multiplex the PUCCH-BFR with the at least one other signal according to the rules.

Abstract: The disclosure describes configuration schemes for secondary cell (SCell), bandwidth part (BWP) and physical resource block (PRB) indexing. An apparatus of user equipment (UE) for BWP activation and deactivation operation is disclosed. The apparatus includes baseband circuitry that includes a radio frequency (RF) interface, and one or more processors. The one or more processors are to receive radio resource control (RRC) data via the RF interface, configure a timer for a BWP according to the RRC data, and trigger the timer for the BWP in response to detection of an event associated with an access node after the BWP has been activated.
