Abstract: Embodiments disclosed relate to apparatuses, systems, and methods for improved handling of phase noise (PN) in millimeter wave (MMW or mmWave) communications in a wireless communication system, such as 5G NR. When severe phase noise is present in a communication link, the link performance can be substantially degraded. Thus, it would be desirable to utilize techniques to compensate for phase noise in mmWave communications. In Rel-15, a Phase Tracking Reference Signal (PT-RS or PTRS) was specified for both downlink and uplink communications, specifically for Cyclic Prefix-Orthogonal Frequency Division Multiplexing (CP-OFDM) and Discrete Fourier Transform spread Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). However, prior art approaches to PTRS using block-based pilot allocation schemes required complicated receiver processing.

Mechanisms are provided for the base station to signal to the UE certain channel access profile parameters, such as an appropriate LBT Cat, CAPC, and/or CP extension.
