Abstract:
A method for transmitting a PTRS, a terminal, and a network device are disclosed in this disclosure. The method includes: acquiring target DMRS ports corresponding to two PTRS ports respectively in a scenario where a terminal performs non-codebook based uplink transmission by using a CP-OFDM waveform; and transmitting corresponding PTRSs to a network device by using respective target DMRS ports.
