In some embodiments, a method of operation of a User Equipment 5 (UE) comprises determining that a reference signal associated with a CSI Reference Signal (CSI-RS) is present on two Orthogonal Frequency Division Multiplexing (OFDM) symbols onto which the CSI-RS is mapped. The reference signal is a reference signal that is present on OFDM symbols only when CSI-RS is present on the OFDM symbols. The method further comprises producing at 10 least one phase error estimate for the CSI-RS that is mapped onto at least one of the two OFDM symbols based on the reference signal, compensating for phase error on at least one of the two OFDM symbols based on the at least one phase error estimate, and generating and reporting CSI based on the CSI-RS after compensating for phase error."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Phase tracking reference signal for NR CSI-RS","description":"Systems and methods that enable and provide compensation for phase noise when performing Channel State Information (CSI) measurements are disclosed.
