Using game theory for Radio Resource Management of RRC Layer in LTE-A

The radio resource management is one of the important contents of the core key technologies of LTE-A, especially in the RRC (Radio Resource Control) layer. Most radio resource management schemes only consider part of the radio resource, but not the overall system performance. Recently, game theory has become a useful tool in the research on radio resource management. According to the 3GPP, in this article, we focus on how to define the radio resource management in the RRC layer as a game and present the concept of “virtual access users”, which helps to describe the wireless communication environment. Game theory is used to improve the overall performance of RRC layer in LTE-A. To be more specific, in the game, first, the characteristics of RAC (Radio Access Control) and RBC (Radio Bearer Control) are analyzed. Second, we created utility function of the game to balance real users and the “virtual access users”. Third, the best solution of the game is reached, and proved to be reasonable. By computer simulations, we investigate the performance of proposed scheme and analyze our simulation results.
