Claim 6:
7. A user equipment comprising:
at least one processor and a memory, said memory comprising instructions executable by said at least one processor, whereby the user equipment is configured to:
receive, from a radio access node, a configuration message for configuring a phase tracking reference signal (PT-RS) on a radio channel, the radio channel comprising a plurality of subcarriers in a physical resource block (PRB), wherein a subset of the subcarriers in the PRB is allocated for transmission of a demodulation reference signal (DM-RS) through a DM-RS port of the user equipment, wherein the configuration message comprises a bit field comprising n bits that are indicative of at least one subcarrier allocated for transmission of the PT-RS through the DM-RS port among the subset of subcarriers allocated for transmission of the DM-RS through the DM-RS port, and wherein a number of the plurality of subcarriers in the PRB is greater than 2n, and
transmit, to the radio access node, the PT-RS on the at least one subcarrier that is allocated for transmission of the PT-RS according to the configuration message from among the subset of subcarriers allocated for transmission of the DM-RS for the DM-RS port.
