METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING DOWNLINK CONTROL INFORMATION FOR REPEATER

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus for transmitting and receiving downlink control information for a repeater of a radio communication system.SOLUTION: A repeater determines a candidate location on which an R-PDCCH (a repeater physical downlink control channel) is transmitted at first and second slots of a downlink sub-frame (S2810); monitors whether the R-PDCCH is transmitted on the determined candidate location (S2820); and receives the downlink control information included in the R-PDCCH when the transmission of the R-PDCCH is monitored (S2830). The R-PDCCH candidate location is set as a VRB set including n virtual resource blocks (VRBs), and a candidate location of one R-PDCCH for a high combination level can be composed of a combination of two adjacent candidate locations of the R-PDCCH candidate locations for a low combination level.
