A novel power control scheme in OFDMA uplink

In OFDMA cellular system, in order to get high spectral efficiency, the fractional power control scheme is always used in the uplink, which fractionally compensates the pass loss to the serving cell. Meanwhile, the inter-cell interference is the dominating interference of the OFDMA cellular system, which greatly degrades performance of the cell edge user. In this paper, we propose a novel uplink power control scheme, which not only compensate the pass loss to the serving cell, but also take the inter-cell interference to the neighbor cell into consideration. The proposed power control scheme can provide a better tradeoff between average throughput and the cell edge throughput. Besides, it can make inter-cell interference more steady compared to the conventional fractional power control scheme.
