摘要： Provided are phase tracking reference signal (PTRS) configuration, determination and information feedback methods and devices. The PTRS configuration method includes: transmitting, by a first node, the control information to a second node, where the control information is used for indicating a configuration parameter of the PTRS to the second node and the PTRS is transmitted by the first node or the second node. The second node determines the configuration parameter of the PTRS through the control information transmitted by the first node and/or an agreed implicit rule. A third node transmits control information to a fourth node, where the control information is used for feeding received power or quality information of the PTRS back to the fourth node.
