Abstract
Official abstract text for this publication.
A method and apparatus for channel interleaving in a wireless communication system. In one aspect of the present invention, the data resource elements are assigned to multiple code blocks, and the numbers of data resource elements assigned to each code block are substantially equal. In another aspect of the present invention, a time-domain-multiplexing-first (TDM-first) approach and a frequency-domain-multiplexing-first (FDM-first) approach are proposed. In the TDM-first approach, at least one of a plurality of code blocks are assigned with a number of consecutive data carrying OFDM symbols. In the FDM-first approach, at least one of the plurality of code blocks are assigned with all of the data carrying OFDM symbols. Either one of the TDM first approach and the FDM-first approach may be selected in dependence upon the number of the code blocks, or the transport block size, or the data rate.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for data transmission, the method comprising: segmenting a transport block into multiple code blocks; encoding the multiple code blocks separately by using a turbo code; selecting coded bits for each of the encoded multiple code blocks, where a number of the coded bits for each of the encoded multiple code blocks is obtained based on a total number of available bits and a number of code blocks; and transmitting the selected coded bits on one l…
