The present invention provides an apparatus for transmitting and receiving control information and system information for repeaters and a method thereof. According to the present invention, a base station apparatus is provided for transmitting control information for repeaters, wherein a transmitter transmits, to each repeater, interleaving mode information and information on resource areas in which R-PDCCHs (Relay-Physical Downlink Control Channel) of each repeater are allocated. The information on the resource areas includes the control information for each repeater, and the interleaving mode information is related to the interleaving modes which are applied to the R-PDCCHs that are allocated to each repeater. Furthermore, a processor performs a control operation so that among the R-PDCCHs of each repeater, and R-PDCCH of a first repeater can be allocated with an R-PDCCH of another repeater at a first interleaving mode in a first resource area and an R-PDCCH of a second repeater can be allocated at a second interleaving mode in a second resource area.
