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.

A method for transmitting a phase tracking reference signal (PTRS), comprising:
- acquiring, by a terminal, target demodulation reference signal (DMRS) ports corresponding to two PTRS ports respectively in a scenario where the terminal performs non-codebook based uplink transmission by using a cyclic prefix-orthogonal frequency division multiplexing (CP-OFDM) waveform;
- and
- transmitting, by the terminal, corresponding PTRSs to a network device by using the respective target DMRS ports.
A terminal, comprising a processor, a memory, and a computer program stored in the memory and configured to be executed by the processor, wherein the processor is configured to execute the computer program to implement following steps:
- acquiring target demodulation reference signal (DMRS) ports corresponding to two PTRS ports respectively in a scenario where the terminal performs non-codebook based uplink transmission by using a cyclic prefix-orthogonal frequency division multiplexing (CP-OFDM) waveform;
- and
- transmitting corresponding PTRSs to a network device by using the respective target DMRS ports.
A method for transmitting a phase tracking reference signal (PTRS), comprising:
- determining, by a network device, target demodulation reference signal (DMRS) ports corresponding to two PTRS ports respectively in a scenario where non-codebook based uplink transmission is performed by a terminal through a cyclic prefix-orthogonal frequency-division multiplexing (CP-OFDM) waveform;
- and
- receiving, by the network device by using the respective target DMRS ports, PTRSs transmitted by the terminal.
