    摘要: A data rate matching method is disclosed. More particularly, a rate matching method using at least two parameters is disclosed. The rate matching method includes selecting bits from an input bitstream using a primary-indication parameter for selecting at least one bit and a secondary indication parameter for canceling the selection using the primary indication parameter or additionally selecting unselected bits, and processing the selected bits according to a rate matching mode so as to generate an output bitstream. By using the rate matching method, highspeed processing is realized by a simple calculation and the locations of target bits can be efficiently decided using at least two indication parameters. Accordingly, it is possible to reduce a calculation amount or improve performance.

    摘要: Methods of transmitting data using a plurality of hybrid automatic repeat request (HARQ) process channels sequentially is disclosed. One of the methods of transmitting data through a plurality of HARQ process channels including a first channel and a second channel includes adding offset to a retransmission data block if the first channel which will transmit the retransmission data block is prescheduled (S702) by another data block, the offset representing the difference in a transmission timing point between the second channel in which positive acknowledgement (ACK) signal has been received (S701) and the first channel; transmitting the retransmission data block through the second channel; and transmitting a data block corresponding to the second channel through the first channel.

    摘要: A data transmitting and receiving method is disclosed. In transmitting a response signal for a transmission signal from at least one transmitter, the present invention includes receiving at least one data block from the at least one transmitter, the at least one data block grouped into at least one group and then transmitted by the at least one transmitter, checking whether each data block is successfully received for the at least one data block belonging to the corresponding group per the group, selecting a transmission scheme of transmitting a response signal instructing a presence or non-presence of successful reception of the each data block to the at least one transmitter, and transmitting a response signal for the each data block to the at least one transmitter by the selected response signal transmission scheme. Hence, the present invention reduces overhead of control information necessary for data transmission.
