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.
