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.

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.
