摘要： A method and apparatus for performing effective feedback in a wireless communication system supporting multiple antennas. A method for transmitting CSI of downlink transmission via uplink in a wireless communication system includes transmitting a joint-coded rank indicator (RI) and a first wideband (WB) precoding matrix indicator (PMI) at a first subframe, and transmitting a wideband channel quality indicator (WB CQI) and a second WB PMI at a second subframe. A user equipment (UE) preferred precoding matrix is indicated by a combination of the first PMI and the second PMI. If the RI is Rank-1 or Rank-2, the first PMI indicates one of subsets each having 8 indexes from among 16 indexes of the first PMI of a precoding codebook.

摘要： A method for receiving downlink data by the terminal in a wireless communication system, includes receiving, from a base station, downlink control information for scheduling a short physical downlink shared channel (sPDSCH) on a short physical downlink control channel (sPDCCH), and receiving, from the base station, downlink data on the sPDSCH based on the downlink control information. Here, the sPDCCH and the sPDSCH are based on a first transmission time interval (TTI)-based radio frame structure, wherein the first TTI-based radio frame structure is shorter in time than a second TTI-based radio frame structure related to (i) a physical downlink shared channel (PDSCH) and (ii) a physical downlink control channel (PDCCH). Further, a number of resource element groups (REGs) consisting of a control channel element (CCE) related to the sPDCCH is smaller than a number of resource element groups (REGs) composed of a CCE related to the PDCCH.

摘要： A method is provided for transmitting Acknowledgement/Negative Acknowledgement (ACK/NACK) information in a wireless communication system. A User Equipment (UE) configures a Physical Uplink Control Channel (PUCCH) format 3 for transmission of the ACK/NACK information. The UE transmits the ACK/NACK information for downlink transmission in a downlink subframe set including M downlink subframes in one uplink subframe, wherein M>1. A plurality of serving cells are configured for the UE and include one Primary Cell (PCell) and at least one Secondary Cell (SCell). The UE transmits the ACK/NACK information using a PUCCH format 1b when a first condition is met that comprises a condition in case where the ACK/NACK information corresponds to one Physical Downlink Shared Channel (PDSCH) without a corresponding Physical Downlink Control Channel (PDCCH) received only on the PCell in the downlink subframe set and the ACK/NACK information corresponds to an additional PDSCH indicated by detection of one corresponding PDCCH.
