Abstract: Provided are a method and apparatus for transmitting acknowledgement/not-acknowledgement (ACK/NACK) of a user equipment in a carrier aggregation system. The method includes: assigning first and second control regions as search spaces for a specific cell; detecting scheduling information with respect to the specific cell from the first control region and/or second control region; receiving a data channel from the specific cell on the basis of the scheduling information; and transmitting ACK/NACK indicating a reception acknowledgement for the data channel, wherein if the scheduling information is detected from the first control region, the ACK/NACK is transmitted using a radio resource linked to another radio resource used to receive the scheduling information, and wherein if the scheduling information is detected from the second control region, the ACK/NACK is transmitted using a pre-set radio resource through a higher layer signal.

Abstract: The present invention relates to a method for configuring a starting position of a control channel in a wireless communication system, and a terminal using the same. The method includes receiving duration information about a physical downlink control channel from the first orthogonal frequency division multiplexing (OFDM) symbol of a downlink subframe; and configuring a first OFDM symbol after OFDM symbols indicated by the duration information, as a starting point of an enhanced-physical downlink control channel. The downlink subframe includes a plurality of subcarriers in a frequency domain and 12 or 14 OFDM symbols in a time domain. The PDCCH includes the first N (N is a natural number of from 1 to 4) number of OFDM symbols of the downlink subframe. The duration information indicates the N number of OFDM symbols. The E-PDCCH comprises the starting point to the last OFDM symbol of the downlink subframe.

Abstract: A method for indicating a combination between a codeword and a layer in a MIMO communication, system, a layer mapping method, and a data transmission method using the same are disclosed. A minimum number of codeword-layer mapping combinations from among all available combinations based on the’ numbers of all codewords and all layers are pre-defined in consideration of a ratio of a codeword to a layer, a reception performance of a receiver, and reduction of combinations, so that a data transmission method using the predefined combinations is implemented. If a specific one codeword is mapped to at least two layers, a diversity gain can be acquired.
