Abstract
In this paper, soft Fractional Frequency Reuse (FFR) is considered to reduce the co-channel interference and also guarantee the cell edge users data rate. We apply power control in soft FFR and investigate the system performance. Soft FFR divides whole frequency band into multiple subbands with different kinds of transmission power levels and allocates subband according to SINR of cell users. By controlling allocated powers, we can increase the frequency efficiency by using the whole frequency band and also improve the data rate for the cell edge users remarkably by reducing the co-channel interference. If the throughput requirement for the outer region is small, we decrease the power allocated to the outer region which can save power energy while high overall system throughput is achieved.
