1. An apparatus for wireless communication at a user equipment (UE), comprising:
memory; and
at least one processor coupled to the memory and configured to:
receive, from a base station, a downlink control information (DCI) message scheduling a physical downlink shared channel (PDSCH) transmission, the DCI message indicating a second part of the PDSCH transmission having a lower modulation and coding scheme (MCS) than a first part of the PDSCH transmission, wherein the second part of the PDSCH transmission includes contiguous resources in a frequency domain and overlaps in time with the first part of the PDSCH transmission;
receive, from the base station, the first part and the second part of the PDSCH transmission;
estimate at least one of an inter-carrier interference (ICI) or a common phase error (CPE) based on the second part of the PDSCH transmission that has the lower MCS than the first part of the PDSCH transmission; and
decode the first part of the PDSCH transmission including correction for the at least one of the ICI or the CPE based on the ICI or the CPE estimated for the second part of the PDSCH transmission.
