    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.

To block-code kχ-bit first data requiring a received signal quality and k2˜bit second data requiring a different received signal quality, the present invention includes configuring a first block code generation matrix meeting a first minimum hamming distance, configuring a second block code generation matrix meeting a second minimum hamming distance, and configuring a third block code generation matrix including the first block code generation matrix, the second block code generation matrix and a zero matrix of a specific size. Accordingly, the present invention encodes and transmits two data requiring different received signal qualities by one coding scheme, thereby enabling each data to have the required received signal quality in decoding.

    摘要: A channel coding method of variable length information using block code is disclosed. A method for channel-coding information bits using a code generation matrix including 32 rows and A columns corresponding to length of the information bits includes channel-coding the information bits having “A” length using basis sequences having 32-bit length corresponding to columns of the code generation matrix, and outputting the channel-coded result as an output sequence. If “A” is higher than 10, the code generation matrix is generated when (A−10) additional basis sequences were added as column-directional sequences to a first or second matrix. The first matrix is a TFCI code generation matrix composed of 32 rows and 10 columns used for TFCI coding. The second matrix is made when at least an inter-row location or an inter-column location of the first matrix was changed. The additional basis sequences satisfy a value 10 of minimum Hamming distance.

    摘要: The present description relates to a wireless communication system, and more particularly, to a method and apparatus for uplink multiple input multiple output (MIMO) transmission. A method for performing an uplink MIMO transmission according to one embodiment of the present invention comprises the following steps: transmitting, from a first subframe, a first data block and a second data block through a first HARQ process and a second HARQ process, respectively; receiving, at a second subframe, uplink scheduling control information on the first data block and control information which indicates inactivation of the second data block; setting HARQ feedback information on the second data block to an ACK state; and performing retransmission of the first data block from a third subframe on the basis of the uplink scheduling control information on the first data block. Retransmission of the second data block may not be performed until uplink scheduling control information on the second data block is received.
