Abstract: Various example embodiments relate to expansion or compression of data of a transport block. A transmitter may comprise: means for receiving data for transmission in a transport block; means for determining, by an expander neural network, an expanded representation for the data of the transport block to cause the data of the transport block to have a designated size, wherein the expander neural network is an encoder of a reverse autoencoder neural network; and means for transmitting the expanded representation of the data in the transport block.
