摘要： A method for efficiently transmitting and receiving downlink control information is disclosed. The method includes, at an base station, receiving feedback information including a preceding matrix index (PMI) from an user equipment (UE) and transmitting precoding information having a predetermined bit number according to the number of antenna ports and a transmission mode of the base station. The preceding information of a predetermined transmission mode in the preceding information includes confirmation information indicating that the base station uses a PMI which is recently received from the UE. At this time, if the confirmation information is transmitted via a specific resource block (RB) of an nth subframe, the PMI which is recently received is received via a resource block of an n−xth subframe or a subframe prior to the n−xth subframe corresponding to the specific resource block. In addition, “x” is a predetermined integer or an integer determined by upper layer signaling of a physical layer or higher.
