Claim 10:
11. An apparatus comprising:
a processor configured to perform computer operation instructions of a memory, causing the apparatus to provide at least the following operations:
determining a power ratio between a phase tracking reference signal (PTRS) and a data channel according to a mapping relationship between a quantity of transport layers and the power ratio,
wherein the power ratio is used for determining a transmit power of the PTRS; and

wherein the mapping relationship comprises:
the power ratio between the PTRS and the data channel is 3 dB when the quantity of transport layers is 2;
the power ratio between the PTRS and the data channel is 4.77 dB when the quantity of transport layers is 3; and
the power ratio between the PTRS and the data channel is 6 dB when the quantity of transport layers is 4,
wherein a quantity of one or more PTRS ports for the PTRS is less than the quantity of transport layers.
