Abstract

The embodiment of the invention provides an information transmission method, a sending terminal device and a receiving terminal device. The information transmission method comprises the following steps: confirming the mother code length N of a Polar code according to the load of a first channel, wherein the load of the first channel is N bits, the N is 2<n>, and the n is a positive integer; performing Polar code coding on the target information to be transmitted to obtain N coded bits; and transmitting the N coded bits through the first channel. In the embodiment of the invention, the number of coded bits obtained after the Polar code coding is equal to the load length of the channel, therefore, the N coded bits is not required to perform a rate matching process when transmitted through the first channel, and the coding overhead of the channel is simplified; and because the rate matching is not required, the complexity and delay of the channel coding are greatly reduced, and the performance loss caused by the rate matching operation is avoided.

Description

technical field [0001] The present invention relates to the communication field, in particular to an information transmission method, a sending end device and a receiving end device. Background technique [0002] The rapid evolution of wireless communication indicates that the fifth generation (Fifth Generation, 5G) communication system will present some new features in the future. The three most typical communication scenarios include enhanced mobile broadband (Enhance Mobile Broadband, eMBB), mass machine connection communication (Massive Machine Type Communication, mMTC) and Ultra Reliable and Low Latency Communications (URLLC). The requirements of these communication scenarios will pose new challenges to the existing Long Term Evolution (Long Term Evolution, LTE) technology. Communication systems usually use channel coding to improve the reliability of data transmission and ensure the quality of communication. As the most basic wireless access technology, channel codin...
