This paper proposes and studies performance of reconfigurable intelligent surface (RIS)assisted multi-hop schemes employing short packet communication (SPC).In the proposed schemes, a source sends its data to a destination, and one RIS is deployed to assist the data transmission at each hop.For complexity reduction purposes, we propose two RIS-assisted data transmission methods at each hop.In the first one, the RIS is only used when the quality of the direct link is not good.In the second one, the direct link or the relay link via the RIS is selected for the data transmission.We evaluate performance of the two proposed schemes by deriving formulas of end-to-end block error rate (BLER-e2e) over Rayleigh fading channel.Finally, the derived BLER-e2e expressions are validated by computer simulations.
