Abstract
Methods and apparatuses for phase noise suppression. In an example method, a first device generates a first signal and sends the first signal to a second device. The first signal includes one or more discrete Fourier transform-spread orthogonal frequency division multiplexing (DFT-s-OFDM) signals. Each of the one or more DFT-s-OFDM signals includes P block-phase noise tracking pilot signal (Block-PTRS) patterns. Each of the P Block-PTRS patterns includes Q phase noise tracking pilot signals (PTRSs). The Q PTRSs include Q(1) real part PTRSs and Q(2) imaginary part PTRSs.
