Abstract: 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 ⅓; 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 can be improved at same power consumption or less power consumption.

Abstract translation: 本发明的实施例提供了一种用于数据交换服务的信道编码方法和装置。 该方法包括：对源数据进行编码以产生第一比特流，其中源数据的数据部分的码率为p，p小于1/3; 打孔第一比特流以产生第二比特流; 以交织的方式将第二比特流映射到q个突发，以产生用于调制的q个突发序列，其中第二比特流完全占据q个突发序列的每个突发序列，并且q是大于4的整数; 以及将q个调制的脉冲串序列发送到接收端。 在本发明的实施例中，减少了数据交换业务的信道编码的码率，从而可以在相同的功耗或较少的功耗下提高终端数据传输的可靠性。
