COMMUNICATION METHOD AND COMMUNICATION APPARATUS

原文（中国語）

This application provides a communication method and a communication apparatus. In the method, a first device determines a scrambling code sequence and a resource block in current transmission based on a mapping relationship between a scrambling code sequence set and a resource block set in the current transmission and a to-be-transmitted information bit. This helps avoid collisions among users by preventing them from using same scrambling code sequences and resource blocks in every transmission. The first device scrambles the information bit based on the scrambling code sequence, to obtain scrambled data in the current transmission, and sends the scrambled data on the resource block. Codeword weight of the scrambled data is within a preset range, allowing the first device to adjust the codeword weight of the scrambled data, thereby enhancing a check capability of a receive end.
