Method for transmitting sounding reference signal, terminal device and network device

A method for transmitting a sounding reference signal (SRS), comprising:

• receiving, by a terminal device, Radio Resource Control (RRC) signaling from a network device;
• determining, by the terminal device according to the RRC signaling, last M second time-domain resource units within a first time-domain unit for transmitting the SRS, and M is an integer;
• determining, by the terminal device according to a hopping pattern, target frequency-domain resources for transmitting the SRS on each of the last M second time-domain resource units;
• and
• transmitting, by the terminal device on the last M second time-domain resource units, the SRS to the network device according to the target frequency-domain resources.
