Abstract
The apparatus may be a wireless device configured to transmit, for a network device, a first indication mapping each of a plurality of residual integrated phase noise powers (RIPNPs) to a corresponding number of subcarriers, receive, based on the first indication, a second indication of a number of subcarriers including a phase tracking reference signal (PTRS), receive, via one or more symbols, a transmission including a data signal and the PTRS over the number of subcarriers indicated in the second indication, and perform a demodulation of the data signal using a phase noise estimation based on the PTRS. The apparatus may be a network device configured to obtain, from a wireless device, the first indication, output, based on the first indication, the second indication, and transmit, via one or more symbols, the transmission including the data signal and the PTRS.
