A Zero Determinant Approach for Power Control of Multiple Wireless Operators in LTE Unlicensed
With increasing mobile data services in the wireless communication networks, the LTE unlicensed is put forward as an effective way to offload the crowded traffic in the licensed spectrum. However, when there are multiple wireless cellular operators (WCOs) sharing the common unlicensed spectrum together, how to manage the competitions among all WCOs while guaranteeing the performance of the Wi Fi networks still remains to be a technical challenge. In this paper, we model a layered power control game among all the WCOs and the Wi Fi access point (WAP) In the game, we first fix the behaviors of all the other WCOs and propose the zero determinant strategy for the power control of one considered WCO. Based on the predicted strategies of every WCO in all situations, all WCOs then play a non cooperative game and determine their optimal strategies to achieve the Nash equilibrium results. Simulation results show the correctness of the analysis and the high performance gain achieved with the proposed zero determinant strategies.
