Claim 5:
6. A method comprising:
receiving a phase tracking reference signal (PTRS);
receiving a data channel mapped to a plurality of transport layers; and
wherein a power ratio between the PTRS and the data channel and a quantity of the plurality of transport layers meet a mapping relationship comprising:
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.
