Utility based resource allocation strategy in multi-cell orthogonal frequency-division multiplexing (OFDM) system is vital in next generation mobile communication system. Based on the analysis of risk aversion utility functions, this paper proposed the system utility based utility, which is named the Customer Satisfaction (CS) utility. Compared with the Proportional Fairness (PF) utility, the CS utility reflects the user demands better, and enables the system to adjust its resource allocation according to both the traffic requirements and the resource situation.

Key words:

OFDM, resource allocation, utility, multi-cell
