Abstract: Communication in a wireless network using a phase-tracking reference signal (PT-RS) for orthogonal frequency division multiplexing (OFDM) includes determining one or more PT-RS groups of adjacent subcarriers in a resource allocation for a physical uplink shared channel (PUSCH) or a physical downlink shared channel (PDSCH), encoding data to be transmitted by the PUSCH or the PDSCH in data subcarriers within the resource allocation for the PUSCH or the PDSCH, and encoding phase-tracking reference signals within the one or more PT-RS groups of adjacent subcarriers.

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.

Abstract: A service device (e.g., a user equipment (UE), a new radio NB (gNB), or other network component or network management component) can process or generate a Downlink Control Information (DCI) that schedules a Physical Uplink Shared Channel (PUSCH) transmission in a PUSCH. The PUSCH transmission can be generated based on a Demodulation Reference Signal (DMRS) according to a Discrete Fourier Transform (DFT) spread Orthogonal Frequency Division Multiplexing (DFT-s-OFDM) waveform in uplink. A sequence of the DMRS can be generated based on a Gold sequence and a Pi/2 Binary Phase-Shift Keying (BPSK) modulation.

Abstract: Embodiments of a Generation Node-B (gNB), User Equipment (UE) and methods for communication are generally described herein. The gNB may map data symbols to resource elements (REs) of virtual resource blocks (VRBs). The gNB may interleave the data symbols, on a per-VRB basis, to spatial layers of a multi-layer multiple-input multiple-output (MIMO) transmission. The data symbols may be interleaved based on different interleave patterns of VRB indexes for the spatial layers. The gNB may map the interleaved data symbols of the spatial layers to REs of physical resource blocks (PRBs) for orthogonal frequency division multiplexing (OFDM) transmission.

Abstract: Techniques for full duplex operation of base stations and/or user equipments (UEs) are discussed. One example embodiment comprises one or more processors of a UE configured to: process control messages that comprise a downlink assignment for the UE and an uplink grant for the UE during a subframe in a frequency band, wherein the downlink assignment indicates a first set of UE subarrays, and wherein the uplink grant indicates a second set of UE subarrays; process downlink data received via transceiver circuitry via the first set of UE subarrays, wherein the downlink data is received from a first base station during the subframe via the frequency band; and output uplink data to the transceiver circuitry for transmission via the second set of UE subarrays, wherein the uplink data is output for transmission to a second base station during the subframe via the frequency band.

Abstract: Systems and methods of beam reporting for multiple DL processes are described. A UE receives a beam management processes configuration that provides information about beam management reference signals for beam management procedures. The UE transmits a UE capability report that indicates beam management capabilities of the UE and, later, an indication of whether the UE intends to engage in beam refinement. The UE measures the beam management reference signals and receives a beam reporting message that indicates at least one of the beam management procedures to report. In response, the UE transmits the beam report. The beam report contains beam management reference signal measurements of the beam management procedures indicated by the beam reporting message.

Abstract: Embodiments of a User Equipment (UE), a generation Node-B (gNB) and methods for communication are generally described herein. The UE may the UE 102 may receive from a gNB, control signaling that indicates: a first pre-coding matrix indicator (PMI) that indicates a first pre-coder for a first sub-band; and a second PMI that indicates a second pre-coder for a second sub-band. The first and second pre-coders may be included in predetermined candidate pre-coders. The UE may encode a physical uplink shared channel (PUSCH) block for transmission. The UE may scale the PUSCH block in the first sub-band by the first pre-coder. The UE may scale the PUSCH block in the second sub-band by the second pre-coder.

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.
