A method of wireless communication by a user equipment (UE) includes determining an original amount of uplink data stored in a non-compression buffer, the original amount of data designated to be transmitted to a network. The method also includes predicting, with a machine learning model, an amount of compression gain for the original amount of uplink data. The compression gain is obtained by compressing the original amount of uplink data during a time delay. The method further includes generating a buffer status report based on the original amount of uplink data and the predicted amount of compression gain. The method transmits the buffer status report to the network.
