Abstract

The present application provides a method for transmitting data, a base station, and a terminal device. The method includes: the base station determines a target base matrix from N Raptor-like LDPC base matrices; the base station sends indication information to the terminal device, where the indication information is used to indicate The terminal device uses the target basis matrix for LDPC encoding and decoding. Based on the above technical solution, the base station can determine a target basis matrix from a plurality of Raptor-like LDPC basis matrices that can be used for LDPC encoding and decoding, and indicate the target basis matrix to the terminal device. Further, for the same code rate or the same code length, the base station can select different basis matrices according to requirements.

Description

technical field [0001] The present application relates to the field of communications, and more particularly, to a method, a base station and a terminal device for transmitting data. Background technique [0002] Fifth generation communication system (5 th Generation, 5G) Enhanced Mobile Internet (Enhance MobileBroadband, eMBB) scenario has been determined to use Raptor-like Low Density Parity Check Code (Low Density Parity Check Code, LDPC) as data channel coding. [0003] Taking the Raptor-like LDPC base matrix that may be used in 5G communication systems as an example, a Raptor-like LDPC base matrix (base graph) can encode code blocks with lengths from 40 bits to 8192 bits to be encoded, and the encoding code rate ranges from 1 / 5 to 8 / 9. However, there are some problems in covering such a wide range of code lengths and code rates through a Raptor-like LDPC base matrix. For example, it is impossible to take into account the encoding and decoding performance of code bl...
