A method for determining a phase-noise compensation tracking reference signal (PTRS) pattern in discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM) system (300), comprising:

• determining, by the DFT-s-OFDM system (300), a number of chunks based on a Power Spectral Density (PSD) of a Phase Noise (PN) samples;
• determining, by the DFT-s-OFDM system (300), a number of samples in each of the chunks based on at least one signal quality metric;
• and
• determining, by the DFT-s-OFDM system (300), the PTRS pattern based on the number of chunks and the number of samples.

A method for optimizing a Channel State Information (CSI) acquisition in an OFDM system, comprising:

• receiving, by a Base Station (BS) (200), a capability information of a User Equipment (UE) (250);
• determining, by the BS (200), a time unit based on at least one of a capability of the UE (250), a channel condition of a link between the BS (200) and the UE (250), and a SCS, wherein the time unit indicates a delay for updating a precoder used for SRS transmission from a Channel State Information Reference Signal (CSI-RS) associated with a Sounding Reference Signal (SRS) transmission at the UE (250);
• indicating, by the BS (200), the time unit to the UE (250) in one of a one-bit Radio Resource Control (RRC) Information Element (IE) and an n-bit RRC IE;
• and
• configuring and transmitting, by the BS (200), the CSI-RS to the UE (250) for a SRS precoder selection based on the time unit and a UE timing advance.
