Analysis of Relay Enhanced Cellular System's Power Saving Characteristic

This paper studies the reverse link power saving characteristic of relay enhanced cellular network, in which the relays are placed at fixed locations and each wireless route includes at most one relay. Results of theoretical analysis and intensive computer simulation have proved that, under the same demand of wireless link qualities as the conventional cellular network, the necessary transmission powers of mobile terminals can be significantly saved even if the relays share the radio resources of the conventional network.
