Abstract: As the LTE standard of the third generation of the mobile communication system being its background, this paper carries out a research on the arithmetic of resource distribution for LTE uplink. It makes an analysis and comparison of advantages and disadvantages of the arithmetic proportional fair, puts forward a complementary proportional fair transposition arithmetic, which can judge the service quality of the RB resource currently distributed to the user and re-distribute the RB resource which is of a lower quality. The simulation shows that the complementary transposition arithmetic is able to seek a favorable balance between the throughput of system and user equity.

Key words: LTE system, uplink, resource distribution, throughput, equity
