RATE DE-MATCHING METHOD FOR DOWNLINK TRAFFIC CHANNEL IN LONG TERM EVOLUTION (LTE) AND DEVICE THEREOF

摘要

A rate de-matching method for a downlink traffic channel in Long Term Evolution (LTE) and a device thereof are disclosed. The method is performed in a terminal side and includes: dividing a received Transmission Block (TB) of a downlink traffic channel, i.e., Physical Downlink Shared Channel (PDSCH) into multiple different Code Blocks (CBs); for the first code block, using a segmentation copy method to achieve rate de-matching; and, for the other code blocks, using a table lookup method to achieve rate de-matching. By applying the method and device provided in the embodiment of the present invention, the execution speed of rate de-matching and the overall speed for processing the downlink traffic channel can be increased.
