Abstract: A generation node B (gNB) for a fifth-generation (5G) new radio (NR) or a sixth-generation (6G) network is configured for slot-less operation at frequencies above a 52.6 GHz carrier frequency. The gNB may generate signalling to configure a user equipment (UE) with a gap between demodulation reference signal (DMRS) symbols for an associated physical downlink shared channel (PDSCH). The gNB may also encode the DMRS symbols for transmission in accordance with the gap and may encode the associated PDSCH for transmission during the gap between the DMRS symbol transmissions at symbol times following the DMRS symbols.

Abstract: Various embodiments herein provide techniques for reference signal (RS) configuration for high frequency bands (e.g., frequency above 52.6 GHz). For example, embodiments may include techniques for configuration of a demodulation reference signal (DM-RS), a channel state information reference signal (CSI-RS), and/or a sounding reference signal (SRS). The RS configuration may provide a low peak-to-average power ratio (PAPR) compared to prior techniques. Other embodiments may be described and claimed.

Abstract: User equipment (UE) can include processing circuitry configured to decode radio resource control (RRC) signaling from a base station, the RRC signaling indicating a transmission coding scheme for a physical uplink shared channel (PUSCH) transmission. PUSCH-to-phase tracking reference signal (PT-RS) energy per resource element (EPRE) ratio is determined using the RRC signaling. A PT-RS power boosting factor is determined based on the transmission coding scheme and the PUSCH-to-PT-RS EPRE ratio. The PT-RS is encoded for transmission using a plurality of PT-RS symbols, the transmission using increased transmission power corresponding to the PT-RS power boosting factor. The RRC signaling further includes a flag enabling the PT-RS transmission. The PUSCH-to-PT-RS EPRE ratio is 00 or 01, and the transmission coding scheme is a codebook-based uplink transmission or non-codebook-based uplink transmission.
