Abstract
- In order to control the level of interference among adjacent small-cells effectively,in this paper,we suppress the interference between adjacent small-cells through controlling the small-cell downlink transmission power.Meanwhile,we use a low complexity subcarrier allocation scheme,making small-cell downlink rate be improved as much as possible.In small cell downlink transmission power control,we use a generalized water-filling algorithm which gives the optimal solution of downlink transmission power.Simulation results show that subcarrier allocation scheme and power allocation algorithm can improve small-cell downlink transmission rate and control the level of interference between adjacent small-cell effectively.
