Based on a recently proposed L_1-norm quantitive fairness measure, the optimal tradeoff between sum rate and fairness for MISO downlink communication employing zero-forcing dirty paper coding is provided in this paper. The corresponding achievable schemes are also given for every point lying on the tradeoff. In particular, a novel power allocation scheme that takes into account both sum rate and fairness is proposed. Compared to the popular approach of proportional fairness, simulation results show that the new scheme can significantly and simultaneously improve upon the achieved sum rate and fairness.
