Classification: CPC H | IPC H

Claim 18:
19. A non-volatile computer-readable medium that stores instructions that, when executed, cause one or more processors of a device to:
obtain a physical shared channel allocation, wherein the physical shared channel allocation comprises a number of physical resource blocks (PRBs) and one or more phase tracking reference signal (PTRS) frequency bands within the PRBs, wherein the one or more PTRS frequency bands comprise one or more PTRS signals;
receive a signal based on the physical shared channel allocation;
filter the received signal to extract the one or more PTRS frequency bands;
process the one or more PTRS frequency bands to obtain one or more time domain PTRS signals;
estimate a phase noise for each PTRS frequency band of the one or more time domain PTRS signals; and
apply the phase noise estimates to the received signal to create a noise-compensated signal.
