摘　　要：通信数据传输过程中一个多播组的中继转发数据会对另外的多播组数据传输产生影响,基于多组多播传输机制提出了一种减少干扰的中继选择方案。该方案以第二时隙对另一个多播组所产生的干扰量作为中继选择因素,根据信道状态和用户地理位置信息,从每个用户作为中继对另一个多播组所产生干扰最小的概率去研究。仿真表明该方案具有一定的可行性。The transmission of a multicast group in the process of relaying data will influence the other multicast data transmission.It proposes a relay selection scheme to reduce interference based on multicast group transmission mechanism.In the scheme,the interference amount of the second time slot on the other multicast group is as the relay selective factor.Based on channel state and user location information,it studies the minimum probability of the interference of each user as relay on the other multicast group.Simulation results show the feasibility of the proposed scheme.
