1. A method of wireless communication by a user equipment (UE), comprising:
transmitting an indication based on a UE capability to simultaneously receive downlink data from a serving cell on one or more first resources and measure one or more channel state information (CSI) reference signals (CSI-RSs) from a target cell on one or more second resources, wherein the one or more first resources at least partially overlap the one or more second resources in a time domain and a frequency domain; and
performing a CSI-RS measurement procedure, based on the UE capability, wherein:
the UE lacks the UE capability when the UE comprises a single processing engine configured to process the downlink data and measure the one or more CSI-RSs, the single processing engine being configured to use a first Fast Fourier Transform (FFT) window based on a first timing of the serving cell; and
when the UE lacks the UE capability, performing the CSI-RS measurement procedure comprises:
reconfiguring the single processing engine to use a second FFT window based on a second timing of the target cell during a set of the one or more first resources; and
using the reconfigured single processing engine to measure the one or more CSI-RSs on the one or more second resources during the set of the one or more first resources.
