  • De-rate matching method and device for downlink traffic channel in long term evolution
    Patent number: 8958330
    Abstract: The present invention discloses a de-rate matching method and device for a downlink traffic channel in a Long Term Evolution (LTE). The method comprises: at a terminal side, dividing a received Transport Block (TB) of a downlink traffic channel, i.e., Physical Downlink Shared Channel (PDSCH), into a plurality of different code blocks; for the first code block, de-rate matching of data is implemented by a segmented copy method; and for the other code blocks, de-rate matching is implemented by a table lookup method. By applying the method and device provided in the embodiments of the present invention, the execution speed of the de-rate matching can be improved, and the overall processing speed of the downlink traffic channel can be improved.
