Abstract: A method for transmitting downlink control information and a method for generating a codeword for the same are disclosed. In generating a long code having a low code rate, a basic code of which minimum distance between codes is maximized is repeated by a prescribed number of times and bits of the repeated code are adjusted. Therefore, a minimum distance condition between codes of a long code is satisfied and simultaneously the code can be simply generated. Furthermore, control information can be transmitted with a low error rate by using the generated code.

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.

Abstract: A method of performing uplink transmission at a user equipment (UE) is provided. The UE determines whether a hybrid automatic repeat request (HARQ) retransmission collides with a transmission for a random access in a time interval, and performs the HARQ retransmission when the HARQ retransmission does not collide with the transmission for random access in the time interval. A current value of information indicating a redundancy version (RV) for the HARQ retransmission is incremented by 1 when the HARQ retransmission does not collide with the transmission for random access in the time interval.
