Problems solved by technology

In related technologies, the fading characteristics of wireless channels may be different in different time-frequency resource positions, and allocating CBs of the same CBG to adjacent time-frequency resource positions may lead to the inability to make full use of the time domain and frequency domain of the wireless channel diversity

Abstract

The present disclosure relates to a distributed physical layer resource mapping method, device, sending end and receiving end. The method includes: encoding the N source information code blocks obtained by dividing the data to be transmitted to obtain N transmission code blocks; dividing the N transmission code blocks into M code block groups according to the first arrangement order, and each code block The block group contains at most P transmission code blocks; and the N transmission code blocks are mapped to physical layer time-frequency resources according to a second arrangement sequence. The technical solution of the present disclosure can improve the time-domain and frequency-domain diversity of wireless channels by mapping information bits of CBs in the same CBG to distributed physical layer resources.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a distributed physical layer resource mapping method, device, sending end, and receiving end. Background technique [0002] In the Long Term Evolution (LTE for short) system, when data is transmitted between the user equipment and the base station, the data sender can divide a large data transmission block into multiple code blocks according to certain rules. After receiving the code blocks, the data receiving end can decode each code block, and feed back the decoding result to the data sending end through a Hybrid Automatic Repeat reQuest (HARQ for short) mechanism. [0003] Since the number of code blocks transmitted in each transmission unit may be relatively large, the data receiving end may cause a huge signaling overhead to feed back the decoding result of each code block. Therefore, in the fifth generation mobile communication technology (5thGeneratio...
