Abstract

In this paper, we proposed the addition of 2 new bits in Downlink Control Information (DCI) format 2D used for Transmission Mode 10 in 3GPP LTE-A specification. This New Downlink Control Information Design with two new bits extends the Downlink Demodulation Reference Signal (DMRS) so that the Physical Downlink Shared Channel (PDSCH) shall be processed and mapped to Resource Elements (RE) mapping and Quasi-Co-Location (QCL) parameter for a User Equipment UE. The new design was analyzed for Multi-user MIMO (MU-MIMO) and Coordinated Multi-point Transmission (CoMP) techniques. The analysis and simulation results indicate that DCI format 2D with the additional bits used with the CIF field are beneficial for both MU-MIMO and CoMP.
传输模式下的新型下行控制信息设计方法
在本文中,我们建议在下行链路控制信息(DCI)格式2D中增加2个新比特,用于3GPP LTE-A规范中的传输模式10。这种具有两个新位的新的下行链路控制信息设计扩展了下行链路解调参考信号(DMRS),以便对物理下行链路共享信道(PDSCH)进行处理并映射到用户设备UE的资源元素(RE)映射和准协同定位(QCL)参数。分析了多用户MIMO (MU-MIMO)和多点协调传输(CoMP)技术的新设计。分析和仿真结果表明,带有CIF字段的DCI格式2D对MU-MIMO和CoMP都是有益的。
