Abstract—The unbalanced traffic load in the service area is
unavoidable, and it can deteriorate the system performance. In
this paper, the improved algorithm of dynamic pilot power
adjustment is proposed and analyzed. The primary theory of
this algorithm is to regulate the serving user number of each cell
by adjusting its common pilot transmission power, according to
the traffic load distribution, and finally achieve the load
balancing in the system. We perform system simulation to
evaluate the algorithms. The simulation results show the
proposed algorithm can evidently balance the traffic load among
the service cells, and it can improve the system capacity to a
certain extent.
