Abstract

Certain aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for phase noise (PN) mitigation on multiple component carriers (CCs). A method that may be performed by a user equipment (UE) includes estimating impairments (e.g., common phase error (CPE) and/or inter-carrier interference (ICI)) caused by PN for only a first CC configured for the UE, wherein the first CC is configured with pilots for PN mitigation and mitigating the PN on each CC for all CCs configured for the UE based, at least in part, on the estimated impairments for the first CC.
