摘要:
提出一种基于协作多点传输的下行多小区多输入多输出(MIMO)系统联合调度机制,充分利用多小区间的联合调度来降低小区间的干扰,提高系统的吞吐量.该方案利用多小区基站间的协作,根据用户反馈的信道信息间的相关性,在不牺牲系统资源情况下联合调度互相干扰小的用户抑制小区间的干扰.仿真表明:该方案在相同情况下与传统的多小区下行MIMO系统相比,具有显著的小区平均系统吞吐量增益及边缘用户吞吐量增益.
Abstract:
A novel jointly schedule scheme for downlink multicell multiple-input multiple-output(MIMO) systems based on coordinated multiple point transmission and reception is proposed in this paper,which improves the system throughput by exploiting the jointly schedule among cells to reduce the inter-cell interference.The proposed scheme uses the cooperative among the base stations and then according to the channel correlation among the uses,which is fed back by the user.As a result,the system can jointly schedule the users which cause the low level inter-cell interference to reduce the inter-cell interference,when it does not waste the resource.It outperforms good average cell throughput gain and cell-edge user throughput gain over the traditional downlink multicell MIMO system at the same situation.
