1. A position determination method for a reference signal, comprising:
acquiring indication information; and
determining a frequency domain position of a first phase tracking reference signal (PTRS) and a frequency domain position of a second PTRS according to the indication information and a predefined mapping relationship, wherein the predefined mapping relationship indicates a mapping relationship between the indication information and the frequency domain position of the first PTRS and a mapping relationship between the indication information and the frequency domain position of the second PTRS,
wherein the frequency domain position of the first PTRS is a frequency domain position of a downlink PTRS indicated by first beam-related information or a frequency domain position of an uplink PTRS indicated by first beam-related information; the frequency domain position of the second PTRS is a frequency domain position of a downlink PTRS indicated by second beam-related information or a frequency domain position of an uplink PTRS indicated by second beam-related information; and beam-related information is transmission configuration indication or spatial relationship information.
