Abstract
An OFDM symbol generation method and a communication device are provided. The method includes: generating a target sequence based on a PTRS bit sequence, wherein the target sequence includes a symbol sequence generated by inserting the PTRS bit sequence into a data bit sequence and performing modulation, a symbol sequence generated by inserting a modulated symbol sequence of the PTRS bit sequence into a modulated symbol sequence of the data bit sequence and performing phase-rotation, or a symbol sequence generated by inserting a PTRS symbol sequence into a data symbol sequence, the PTRS symbol sequence is generated by modulating the PTRS bit sequence according to an index of a PTRS bit, the data symbol sequence is generated by modulating the data bit sequence according to an index of a data bit; and generating the OFDM symbol based on the target sequence.
