Abstract
According to certain embodiments, a user equipment (810) is provided for us in a cellular network. The user equipment (810) may include a transceiver (910), a processor (920), and a memory (930). The user equipment (810) may be configured to acquire a Demodulation Reference Signal (DMRS) configuration. A mapping is determined from the DMRS configuration to a phase noise tracking reference signal (PNT-RS). A channel estimate is performed using the DMRS configuration. Phase noise estimation and compensation is performed based on the PNT-RS by using the mapping and the channel estimate.

A method by a receiver for use in a cellular network, the method comprising:
- acquiring a Demodulation Reference Signal (DMRS) configuration;
- determining a mapping to a PNT-RS transmission from the DMRS configuration;
- performing a channel estimate using the DMRS configuration;
- and
- performing phase noise estimation and compensation based on the PNT-RS, using the mapping and the channel estimate.
A receiver for use in a cellular network, the receiver comprising a transceiver, a processor, and a memory, the receiver configured to:
- acquire a Demodulation Reference Signal (DMRS) configuration;
- determine a mapping to a PNT-RS transmission from the DMRS configuration;
- perform a channel estimate using the DMRS configuration;
- and
- perform phase noise estimation and compensation based on the PNT-RS, using the mapping and the channel estimate.
A method by a transmitter, the method comprising:
- sending a Demodulation Reference Signal (DMRS) configuration, the DMRS configuration being associated with a mapping to a PNT-RS transmission;
- and
- transmitting a PNT-RS to a receiver according to the mapping.
