Abstract: In legacy systems such as 3rd Generation Partnership Project (3GPP) releases 8 to 10, the control channel is transmitted using the first few Orthogonal Frequency Division Multiplexing (OFDM) symbols in a subframe. The limited control channel capacity will impact the system performance in future releases as more and more User Equipments (UEs) will be scheduled in a subframe with technologies such as MulitUser-Multiple Input Multiple Output (MU-MIMO) and Coordinated Multipoint (CoMP) transmission being enhanced or introduced. A new Enhanced Control CHannel (E-CCH) is necessary to be designed, which will use the resource in the Physical Downlink Shared CHannel (PDSCH) in the legacy systems. The E-CCH will support UE-specific DeModulation Reference Signal (DMRS) based transmission and receiving. However, the configuration of DMRS for E-CCH is necessary to be known to UE in prior. This invention discloses multiple methods in which DMRS is configured for E-CCHs and respective eNB and UE behaviors.
