Wireless communication method, terminal device, and network device

A wireless communication method, comprising:

• determining, by a network device, a number N of phase tracking reference signal (PTRS) ports used for uplink transmission of X antenna ports, wherein X is an integer greater than 4;
• determining an antenna port and a transport layer associated with each PTRS port of N PTRS ports;
• receiving, based on the number N of the PTRS ports, a PTRS on at least some PTRS ports of the N PTRS ports;
• and
• performing, based on a phase measurement result of the PTRS, a channel estimation of the demodulation reference signal (DMRS) associated with the at least some PTRS ports or a phase adjustment of a transport layer associated with the PTRS ports.

A terminal device, comprising:

• a processor and a memory, wherein the memory is configured to store a computer program, and the processor is configured to call and run the computer program stored in the memory to cause the terminal device to perform:
• determining a number N of phase tracking reference signal (PTRS) ports used for uplink transmission of X antenna ports, wherein X is a positive integer greater than 4;
• determining an antenna port and a transport layer associated with each PTRS port of N PTRS ports;
• determining a power boosting value of the each PTRS port of the N PTRS ports;
• and
• transmitting, based on the antenna port and the transport layer associated with the each PTRS port, as well as the power boosting value of the each PTRS port, a PTRS on at least some PTRS ports of the N PTRS ports.
