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.

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.

Abstract: Herein described are apparatuses, systems, and methods for measurement and reporting of channel state information within wireless network systems. In embodiments, an apparatus for a user equipment (UE) may include memory to store a rank indicator (RI), a precoding matrix index (PMI), and a channel quality indicator (CQI) of channel state information (CSI) for the UE. The apparatus may further include circuitry to concatenate the RI, the PMI, and the CQI to produce a concatenated CSI element, generate a CSI report that includes the concatenated CSI element, and cause the CSI report to be transmitted to a base station within a single slot. Other embodiments may be described and/or claimed.

Abstract: The present disclosure provides systems and methods for mapping transmission configuration indication (TCI) states to demodulation reference signal (DMRS) ports groups in a wireless network. For instance, a TCI state to DMRS ports group mapping of a user equipment (UE) can be determined. Each DMRS port in a DMRS ports group shares a quasi-co-location (QCL) assumption. The TCI state to DMRS ports group mapping comprises multiple TCI state groups. The TCI state to DMRS ports group mapping corresponds each TCI state group to one or more DMRS ports groups. A TCI state group from the DMRS ports group mapping can be selected for the UE. Data indicative of the selected TCI state group and the corresponding one or more DMRS ports groups can be provided to the UE based at least in part on the TCI state group from the DMRS ports group mapping.

Abstract: Systems, apparatuses, methods, and computer-readable media are provided for framework of layer 1 signal-to-interference plus noise ratio (L1-SINR) measurement and reporting based on channel measurement and interference measurement. The channel measurement is performed on a first set of reference signal (RS) resources, and the interference measurement is performed on a second set of RS resources. Each of the second set of RS resources is mapped to each of the first set of RS resources. The L1-SINR is determined from a first RS resource of the first set of RS resources and a second RS resource of the send set of RS resources, where the first RS resource is mapped to the second RS resource. A message including the L1-SINR is generated and transmitted to the access node.

Abstract: An apparatus configured to be employed in a user equipment (UE) associated with a new radio (NR) communication system is disclosed. The apparatus comprises one or more processors configured to process a physical downlink shared channel (PDSCH) scheduling signal, received from a gNodeB associated therewith, wherein the PDSCH scheduling signal is configured to schedule a transmission of PDSCH. In some embodiments, the PDSCH scheduling signal comprises a transmission configuration indicator (TCI) state indicative of a channel state information reference signal (CSI-RS) resource that is triggered aperiodically. In some embodiments, the apparatus is further configured to determine a receive (Rx) beam to be utilized for the reception of the scheduled PDSCH transmission, that forms a PDSCH Rx beam, based on the indicated CSI-RS resource.
