Inventors include Zhang, Rui; Tsai, Shiauhe Shawn; and Chou, Tzu-Han Number.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: A method of generating a comb reference signal (RS) pattern over a discrete-Fourier-transform-spread orthogonal frequency division multiplexing (DFT-s-OFDM) symbol includes repeating a time-domain sequence with a number of repetition to obtain a repeated time sequence; performing a phase rotation for the repeated time sequence to obtain a phase-rotated time sequence; concatenating a plurality of phase-rotated time sequences; and performing a DFT-s-OFDM operation for the plurality of phase-rotated time sequences.
