Abstract: An apparatus of user equipment (UE) includes processing circuitry coupled to a memory, where to configure the UE for DMRS processing in an NR network, the processing circuitry is to decode higher layer signaling, the higher layer signaling to indicate whether transform precoding is enabled and to indicate a modulation scheme for a physical uplink shared channel (PUSCH) if transform precoding is enabled. A set of low Peak-to-Average-Power-Ratio (PAPR) base sequences of length-6 is generated. A reference signal sequence is generated as a demodulation reference signal (DMRS) using the set of low-PAPR base sequences, based on the modulation scheme if transform precoding is enabled by the higher layer signaling, the modulation scheme being a π/2-binary phase-shift keying (BPSK) modulation scheme. Mapping of the DMRS to physical resources for transmission using the PUSCH is performed.

Abstract: Technology for a next generation node B (gNB) operable to transmit in multiple bandwidth parts (BWPs) is disclosed. The UE can determine a channel state information reference signal (CSI-RS) symbol location in a first bandwidth part (BWP). The UE can determine a CSI-RS symbol location in a second BWP. The UE can encode the CSI-RS in one or more of the first BWP or the second BWP for transmission to a user equipment (UE). The UE can have a memory interface configured to send to a memory the CSI-RS symbol location.

Abstract: An apparatus of user equipment (UE) includes processing circuitry coupled to a memory, where to configure the UE for DMRS processing in an NR network, the processing circuitry is to generate a plurality of binary sequences of length L, the binary sequences being arranged according to a signal quality metric. A set of CGSs is generated using the binary sequences, based on minimizing cross-correlation between subsets of binary sequences of different lengths selected from the plurality of binary sequences. A CGS is selected from the set of CGSs as a DMRS, based on uplink PRB resource allocation. The DMRS is encoded for transmission, where the encoding includes BPSK modulation and discrete Fourier transformation (DFT) spreading of the DMRS.

Abstract: Technology for an eNodeB operable to decode a sounding reference signal (SRS) received from a user equipment (UE) is disclosed. The eNodeB can decode the SRS received from the UE, wherein 5 the SRS is received using one or more SRS resources in a subframe where each SRS resource includes one or more symbols. The subframe can be an uplink subframe dedicated for SRS transmission or a short transmission time interval (sTTI) subframe used for SRS transmission. The eNodeB can determine uplink channel quality information for a channel between the eNodeB and the UE based in part on the 10 SRS.

Abstract: Techniques discussed herein can facilitate reduced density CSI (Channel State Information)-RS (Reference Signals). One example embodiment can be employed at a UE (User Equipment) and can comprise processing circuitry configured to: process one or more configuration messages that comprise one or more configuration parameters for one or more CSI (Channel State Information)-RS (Reference Signal) APs (Antenna Ports) of a reduced density CSI-RS, wherein the one or more configuration parameters indicate a PRB (Physical Resource Block) decimation and a PRB offset; determine a set of REs (Resource Elements) for the one or more CSI-RS APs of the reduced density CSI-RS based on the one or more configuration parameters; measure the reduced density CSI-RS from the set of REs to determine one or more CSI parameters.
