Abstract: Embodiments of this application provide a radio channel data processing method, a communication apparatus, and a related device. In the method, a first communication device may send an uplink resource request message to a second communication device. The uplink resource request message includes source distribution information and a first modulation and coding scheme determined based on the source distribution information. The first communication device receives an uplink resource allocation message from the second communication device. The uplink resource allocation message includes a modulation and coding scheme allocated by the second communication device to the first communication device. The first communication device performs modulation and coding on an information bit based on the second modulation and coding scheme. This helps improve coding performance of the first communication device.

Abstract: The present invention discloses a data sending method and apparatus, which resolves a problem that performance of a high coding rate LDPC code obtained in an existing puncturing manner based on a variable node degree distribution is relatively poor. The method includes: encoding, by using an LDPC code check matrix, an information bit that needs to be sent, to obtain a codeword sequence; determining a puncturing priority of each parity bit in the codeword sequence according to row destruction and/or cycle destruction, on the LDPC code check matrix, of a variable node corresponding to each parity bit; puncturing the codeword sequence according to the puncturing priority of each parity bit in the codeword sequence; and generating a bit sequence according to the punctured codeword sequence, and sending the bit sequence. In this way, performance of an obtained high coding rate LDPC code is improved.
