Claim 11:
12. A network node in a wireless communication system configured for one of transmitting and receiving a phase tracking-reference signal, PT-RS, the network node comprising:
processing circuitry configured to:
obtain information about a position in a time domain of a scheduled first demodulation reference signal, DM-RS symbol in a slot;
obtain information about a position of a first time symbol in a slot scheduled for data transmission;
obtain information about a position of a last time symbol in the slot scheduled for data transmission, and;
transmit PT-RS symbols within the slot, the position of the PT-RS symbols depending on the position in the time domain of the scheduled first DM-RS symbol: and
determine potential positions of additional DM-RS symbols, the potential positions of additional DM-RS symbols being a subset of the positions of the PT-RS symbols.
