 note = {In this paper, we propose the soft boundary concept achieved by dynamic titled antenna to solve the issue of traffic congestion occurred in cellular wireless systems. The tilted antenna array can provide the merit of traffic balance and also achieve the optimization of the signal-to-interference ratio (SIR) at receivers by automatically tilting the antenna and impementing the soft boundary among cells, corresponding to the variation of traffic.},
