    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.

    摘要: The present invention discloses a method for transmitting a same pilot sequence from a transmitting end to a receiving end in a multi-antenna wireless communication system. In particular, the method comprises the steps of: setting an identical pilot pattern in a plurality of transmitting antennas, allocating respectively different pilot sequences to the set pilot patterns, and transmitting the allocated pilot sequences to the receiving end, wherein at least one of the transmitting antennas forms a valid communication link with one of the receiving antennas. Here, when there is a plurality of valid communication links, the plurality of communication links are mutually independent.
