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.
