A novel bargaining based power allocation for Coordinated Multiple Point transmission/reception

To explore the benefit of Coordinated Multiple Point transmission/reception (CoMP) will reduce the exchange overhead between the cells, a distributed Rubinstein-Stahl Bargaining based Power Allocation (DBPA) scheme is proposed in this paper. The introduced scheme can provide a possible solution to share the increased benefits, which are obtained at a serving cell when a slaving cell joins to coordinated transmission. By exchanging the Patience Factor (PF) calculated in each cell, a serving cell can determine the optimal power provided from the slaving cell. Furthermore, if the chosen slaving cell could get more utilities from cooperation, it will have incentive to do so. It is obvious that DBPA don´t need a central control point then decrease the information transmission and the simulation results show that it can also achieve comparable performance to that employing centralized scheme.
