Abstract:
According to certain embodiments, a user equipment (810) is provided for use 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.
