초록/요약
Joint transmission, included in coordinated multipoint scheme, can improve the throughput of cell edge users by controlling transmit power of cooperating base stations. This, however, may cause another interference with inappropriate power allocation. In this paper, we model the power allocation of base stations as a game. The cooperating base stations are defined as players in the game and they allocate their power to maximize their utility. In the process, we consider the power constraints of cooperating base stations and the cost factor that reflects the degree of interference in other non-cooperating base stations. We show that there exists a Nash equilibrium in this power allocation game and the simulation results confirm that the proposed approach leads to an equilibrium. © 2017 IEEE.
