1. A phase tracking reference signal (PTRS) configuration method, comprising:
transmitting, by a first node, control information to a second node, wherein the control information is used for indicating a configuration parameter of a PTRS to the second node; and
wherein the PTRS is transmitted by the first node or the second node;
wherein in condition that the configuration parameter is a power configuration parameter, a way for indicating the configuration parameter comprises at least one of:
indicating an offset value through the control information;
indicating an offset reference object through the control information;
indicating a power offset value through precoding information; or
indicating reference signal information associated with power of the PTRS;
wherein the way for indicating the configuration parameter further comprises at least one of:
indicating selection information of an associated SRS port of PTRS port power;
indicating selection information of an associated CSI-RS port of the PTRS port power; or
indicating selection information of an associated BRS port of the PTRS port power.
