1. A method for generating a waveform by one or more transmitters in a communication network, the method comprising:
generating, by the one or more transmitters, at least one data sequence, at least one reference sequence (RS) and at least one phase tracking reference sequence (PT-RS), wherein the at least one of the data sequence, the at least one RS and at least one PT-RS are applied with a corresponding transmitter specific code cover;
time-multiplexing, by the one or more transmitters, the at least one data sequence, at least one RS, and the at least one PT-RS to generate a multiplexed sequence; and
generating, by the one or more transmitters, a filtered DFT-spread-Orthogonal Frequency Division Multiplexing (DFT-s-OFDM) waveform using the multiplexed sequence.
