A unified cooperative radio resource management game

Both fairness and efficiency are natural performance metrics of radio resource management (RRM) in wireless communication systems. However, taking both of them into account simultaneously in one formulated RRM model is non-trivial, because promoting the one typically involves compromising on the other one. In this paper, both symmetric and asymmetric cooperative game-theoretical rate control games are formulated in one unified preference function design. Closed-form of optimal rates are derived for two-player game to achieve optimal tradeoffs between Nash fairness and Nash axiomatic efficiency. We illustrate and provide the analyzed results of both symmetric and asymmetric rate control schemes. Finally, we conclude that the optimal setting of bargaining powers can help to improve both fairness and efficiency of the rate control.
