Method and apparatus for determining and transmitting parameter of reference signal, terminal device and base station

A wireless communication device implemented as a base station, comprising at least one processor that is configured to:

• determine a first parameter associated with a demodulation reference signal;
• determine, according to the first parameter, a second parameter associated with a second reference signal, wherein the second reference signal is related to phase noise compensation and is not a demodulation reference signal;
• and
• transmit the second reference signal according to the second parameter, wherein transmitting the second reference signal and configuration of a time-domain orthogonal sequence for the demodulation reference signal (DMRS) do not occur simultaneously such that, when wireless communication device transmits the second reference signal, the time-domain orthogonal sequence is not configured for the demodulation reference signal and, when the time-domain orthogonal sequence is configured for the DMRS, the wireless communication device does not transmit the second reference signal.
