    摘要: A method of transmitting a midamble for channel estimation of multiple antennas performed by a base station in a system having segregated uplink and downlink frequency bands is provided. The method includes transmitting midamble information indicating presence of the midamble within a downlink frame to a user equipment (UE), and transmitting the midamble on a single downlink subframe among at least one downlink subframe included in the downlink frame or on a common zone to the UE by using the multiple antennas. A scheduling overhead of a base station and other overheads can be reduced by decreasing the number of transmissions of a midamble on one downlink frame, and thus limited radio resources can be effectively used.

    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: Discloses are a method and a device for transmitting midamble signals in a wireless communication system. The method for transmitting the midamble signals comprises the steps of: generating each of midamble signals for eight transmission antennas; and transmitting said midamble signals to a terminal through said eight transmission antennas. Among the midamble signals for said eight transmission antennas, a first midamble group which includes midamble signals for certain four transmission antennas and a second midamble group which includes midamble signals for the rest of four transmission antennas are transmitted through different resources.

    摘要: A method and User Equipment (UE) for transmitting feedback information are disclosed. The UE feeds back M best subbands to a Base Station (BS). Especially, the UE feeds back indication information indicating a combination of the M best subbands from among combinations each having M subbands produced out of a maximum number of subbands that can be allocated. Hence, coding of the feedback information is simplified.
