1. A method for wireless communication at a user equipment (UE), comprising:
determining one or more filter coefficients used by a network entity to filter a reference signal, the one or more filter coefficients being based at least in part on a type of the reference signal, wherein the reference signal is used by the UE to determine channel quality information;
receiving the filtered reference signal from the network entity, the filtered reference signal being filtered by the network entity using the one or more filter coefficients;
receiving a second signal;
determining a type of quasi-collocation of the reference signal and the second signal, wherein the one or more filter coefficients associated with the filtered reference signal and one or more filter coefficients associated with the second signals are based at least in part on the type of quasi-collocation;
measuring the channel quality information based at least in part on the filtered reference signal and the one or more filter coefficients; and
transmitting, to the network entity, the channel quality information that is determined based at least in part on the filtered reference signal and based at least in part on the one or more filter coefficients determined to be used by the network entity.
