Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) with phase noise (PN) suppression capabilities may indicate, to a network node, a quantity of subcarriers corresponding to an assumed PN bandwidth (for example, a portion of a frequency spectrum in which the UE can estimate and cancel PN) and a residual error associated with the assumed PN bandwidth. In some aspects, the network node may then configure a phase tracking reference signal (PTRS) size (for example, a quantity and location of PTRS pilots) according to current the PN suppression capability of the UE. Furthermore, in cases where the UE changes the current PN suppression capability, the UE may indicate the updated PN suppression capability to the network node such that the PTRS size be appropriately updated for subsequent downlink transmissions.
