    摘要: A method of transmitting data in a wireless communication system is provided. The method includes transmitting downlink scheduling information regarding downlink radio resource allocation and uplink scheduling information regarding uplink radio resource allocation on a downlink control channel, transmitting downlink data on a downlink data channel according to the downlink scheduling information, and detecting an acknowledgement (ACK)/negative-acknowledgement (NACK) signal for the downlink data from a radio resource exclusively allocated to the ACK/NACK signal. According to the present invention, when an error occurs in a downlink control channel due to deterioration of a channel condition, the error can be promptly handled using an error detection protocol agreed between a user equipment and a base station. Therefore, data can be transmitted with higher reliability.

    摘要: An STBC based signal transmission method considering the number of symbols within a slot. In transmitting a signal using two or more transmission antennas in a mobile communication system using a structure in which one subframe includes two slots and each slot includes a plurality of symbols, transmission symbols are paired in units of two consecutive symbols within each subframe by an STBC scheme. The transmission symbols are mapped to a frequency region in units of slots and the mapped transmission symbols are transmitted. One symbol within a slot in which the number of symbols excluding symbols for transmitting a reference signal is an odd number is not paired by the STBC scheme.

    摘要: A method for transmitting signals using a hybrid automatic repeat request (HARQ) scheme to guarantee a constellation rearrangement gain having a predetermined level or more is provided. Predetermined code blocks are encoded, sub-block interleaving is performed with respect to the encoded code blocks, and the sub-block interleaved code blocks are transmitted according to redundancy version (RV) start locations of the sub-block interleaved code blocks. The RVs are set such that the order of bit streams modulated by an M-QAM (M>4) scheme is changed upon a retransmission. In addition, the RVs are set such that the RV start locations applied to code blocks having different sizes are different.
