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.

A method includes identifying a set of resource blocks associated with a control channel for a terminal; transmitting, to the terminal, information on the set of resource blocks on a radio resource control signal, the information including first information indicating resource blocks included in the set of resource blocks and second information indicating a number of symbols corresponding to the set of resource blocks; transmitting, to the terminal, control information including information for downlink data on the control channel identified based on the first information and the second information; and transmitting, to the terminal, the downlink data on a data channel based on the control information. The set of resource blocks includes at least one control channel resource. A search space for the control channel of the terminal is defined based on an aggregation level, a number of the at least one control channel resource, and a number of a candidate associated with the control channel.
