摘　　要：针对TD-LTE系统存在的小区间干扰问题,提出一种基于博弈论思想的结合上行链路功率控制(UPC)和小区间干扰协调(ICIC)的小区间干扰抑制策略:首先将小区中用户作为博弈参与者,为每个用户分配一个合适的游戏者身份;然后为每个游戏者分配合适的UPC和ICIC算法使其参与博弈,最终达到抑制小区间干扰,且最大化系统吞吐量的目的.To solve the inter-celi interference problem in TD-LTE systems, a inter-cell interference suppression strategy is proposed based on game theory combination of uplink power control（UPC）and inter-cell interference coordination （ICIC）for TD-LTE communication systems. The main approach is divided into two steps. First, the users in the cell act as the game participants,and each user is assigned an appropriate identity of the player. Second, each player is assigned the UPC and ICIC algorithm makes its participation in the game,which can ultimately inhibit the purpose of inter-cell interference and maximize system throughput.
