1. A method of wireless communication by a user equipment (UE), comprising:
receiving, from a network entity, a message indicating a change in a set of downlink beams for channel state information reference signals (CSI-RSs), and a context associated with the change;
saving state values in an auto-encoder neural network in response to receiving the message;
associating the saved state values in the auto-encoder neural network to the context in the received message;
resetting the state values in the auto-encoder neural network in response to receiving the message;
estimating a channel state based on the CSI-RSs received on the changed set of downlink beams;
compressing the channel state with the auto-encoder neural network based on the reset state values;
sending to the network entity, the compressed channel state; and
feeding back an indication that the resetting occurred.
