Abstract
In fifth generation (5G) new radio (NR), the medium access control (MAC) layer organizes the data into the transport block and transmits it to the physical layer. The transport block consists of up to million bits. When the transport block size exceeds a threshold, the transport block is divided into multiple equal size code blocks. The code block consists of up to 8448 bits. Both the transport block and the code block have a cyclic redundancy check (CRC) attached. Due to the difference in the size of the transport block and the code block, the CRC processing scheme suitable for the transport block and that suitable for the code block are different. This chapter gives an overview of the CRC implementation in 5G NR.
Highlights
In order to provide high data transmission rates, the bandwidth of mobile communication systems is increasing
In fifth generation (5G) new radio (NR), the frequency bands are divided into two parts: frequency range 1 (FR1) below 6 GHz and frequency range 2 (FR2) above 24.25 GHz
In this chapter of the book, we focus on the cyclic redundancy check (CRC) implementation in 5G NR
Summary
In order to provide high data transmission rates, the bandwidth of mobile communication systems is increasing. The medium access control (MAC) layer organizes the data into the transport block and transmits it to the physical layer. If the transport block size is larger than 3824, a 16-bit CRC is added at the end of the transport block. A 24-bit CRC is added at the end of the transport block. For quasi-cyclic low-density parity-check code (QC-LDPC) base graph 1, the threshold is equal to 8448. In 5G NR, the maximum code block size number is 8448. An additional 24-bit CRC is added at the end of each code block when there is a segmentation.
