Embodiment Construction

[0026]In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0027]The present invention provides a code block grouping method, device and computer-readable storage medium in view of the problem that the prior art does not divide the CB grouping into channel resources, which affects communication integrity and cannot guarantee the reliability of NR communication.

[0028]Such asfigure 1 As shown, an embodiment of the present invention provides a method for grouping code blocks, including:

[0029]Step 101: Determine the number of code block groups CBG and the number of code blocks CB in each code block group CBG;

[0030]Step 102: Determine the position of each CBG on the shared channel according to the number of CBs.

[0031]It should be noted that the shared channel is a physical downlink shared channel (PDSCH). The code bl...

Abstract

The invention provides a code block grouping method, a device and a computer-readable storage medium, which relate to the technical field of communication. The code block grouping method comprises thefollowing steps: determining the number of code blocks CB in each code block group CBG; a location of each CBG is determined on a shared channel according to that numb of CBs. In the scheme, the position of each CBG on the shared channel is determined according to the number of CBs in the CBG, so that the grouping of the CBs can be completed according to the goal of improving the decoding performance or realizing the complexity, so as to meet different target requirements.

Description

Technical field[0001]The present invention relates to the field of communication technology, and in particular to a method, device and computer-readable storage medium for grouping code blocks.Background technique[0002]Compared with the past mobile communication system, the future 5G mobile communication system needs to adapt to more diverse scenarios and business requirements. The main scenarios of 5G include enhanced mobile broadband (eMBB), highly reliable communications (URLLC), and large-scale Internet of Things services (mMTC). These scenarios put forward requirements for the system with high reliability, low latency, large bandwidth, and wide coverage. For services in certain scenarios, higher bandwidth transmission is required to provide a higher transmission rate.[0003]Generally, in Long Term Evolution (LTE), a transport block (TB) can be divided into multiple code blocks (CB), and the feedback acknowledgement character / non-acknowledgement character (ACK / NACK) is based on t...
