METHOD FOR TRANSMITTING CONTROL INFORMATION, ESPECIALLY FOR EFFICIENTLY TRANSMITTING UPLINK CONTROL INFORMATION USING A PLURALITY OF CELLS, AND A DEVICE THEREFOR

摘要

PURPOSE: A method for transmitting control information and a device therefor are provided to efficiently manage resources for transmission of control information.;CONSTITUTION: A base station (BS) and user equipment (UE) composes a plurality of downlink (DL) component carriers (CC) (S1102). The BS transmits a single codeword to the UE through multi input multi output (MIMO) DL CC (S1104). The UE feeds back acknowledgement (ACK)/negative acknowledgement (NACK) payload for physical uplink control channel (PUCCH) format 3 to the BS (S1106). The BS and the UE perform operation according to discontinuous transmission (DTX) and NACK decoupling (S1108).;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Terminal; (BB) Base station; (S1102) Compose a plurality of DL CC (MINO DL CC,Non-MIMO DL CC); (S1104) Single codeword via MIMO DL CC; (S1106) ACK/NACK(All NACK and DTX decoupling); (S1108) NACK/DTX motion according to decoupling
