Method for indicating reference signal configuration information, base station, and terminal

A method for wireless communication, comprising:

• receiving, by a terminal device via a higher layer signaling message, multiple sounding reference signal (SRS) resources from a base station, wherein a first SRS resource corresponds to a port identifier of a phase tracking reference signal and a second SRS resource corresponds to the same port identifier of the phase tracking reference signal, wherein a first port corresponding to the first SRS resource and a second port corresponding to the second SRS resource share a same port of the phase tracking reference signal;
• receiving, by the terminal device, a Downlink Control Information (DCI) message from the base station, wherein the DCI message includes a sounding reference signal resource indicator for a sounding reference signal that corresponds to port information of the phase tracking reference signal, wherein the port information of the phase tracking reference signal includes one or more port identifiers that comprises the port identifier of the phase tracking reference signal;
• and
• performing, by the terminal device, an uplink transmission using the port information of the phase tracking reference signal.

A wireless communication device, comprising:
