由于自干扰和用户间干扰，全双工系统上下行链路之间的功率冲突问题问题被耦合在上行链路和下行链路信道之间，并且可以被表示为联合的上行链路和下行链路的和速率最大化。由于该问题是非凸的，因此将此问题建模为上下行信道之间的非合作博弈，提出了一种基于博弈论的迭代算法。(Due to the self-interference and interuser interference, the problem is coupled between uplink and
downlink channels, and can be formulated as joint uplink and
downlink sum-rate maximization. As the problem is non-convex,
an iterative algorithm is proposed based on game theory by
modelling the problem as a noncooperative game between the
uplink and downlink channels.)
