Embodiments of the present invention provide a channel coding method for a data exchange service, and a device. The method includes: coding source data to generate a first bitstream, where a code rate of a data part of the source data is p, and p is less than 1/3; puncturing the first bitstream to generate a second bitstream; mapping, in an interleaved manner, the second bitstream to q bursts to generate q burst sequences, for modulation, where the second bitstream fully occupies each burst sequence of the q burst sequences, and q is an integer greater than 4; and sending the q modulated burst sequences to a receive end. In the embodiments of the present invention, a code rate of channel coding for a data exchange service is reduced, so that reliability of terminal data transmission is ensured and power consumption of a terminal device can also be reduced, or reliability of terminal data transmission can be improved at same power consumption. |
