Title:
METHOD FOR SEGMENTING TRANSMISSION BLOCK, AND WIRELESS COMMUNICATION DEVICE AND CHIP
Document Type and Number:
WIPO Patent Application WO/2018/171627
Kind Code:
A1
Abstract:
Provided are a method for segmenting a transmission block, and a wireless communication device and a chip. The method comprises: acquiring a transmission block to be encoded, wherein the transmission block to be encoded comprises a transmission block and a cyclic redundancy check (CRC) code of the transmission block; determining the length of an input code block according to a first code length and a second code length, wherein the first code length is the maximum input code block length supported by an LDPC encoder, and the second code length is determined according to the maximum output code block length supported by the LDPC encoder; and according to the length of the transmission block to be encoded and the length of the input code block, segmenting the transmission block to be encoded. In the technical solution, the restriction of an LDPC encoder on the length of an input code block and the restriction of the LDPC encoder on the length of an output code block are taken into consideration when a transmission block is segmented. Therefore, the present invention can ensure that the length of the output code block output by the LDPC encoder satisfies the maximum output code block length supported by the LDPC encoder.
