In 5G NR LDPC encoder 2Zc systematic bits are punctured at the transmitter end. At the receiver end, it is able to recover all bits excluding the punctured bits at the transmitter end.

As the systematic bits include the information bits and as it is punctured at the transmitter end while processing through Parity check Matrix processing. Is it possible to recover this elements by soft decoding mechanism with Log likelihood estimation process.

For high code rate it is possible to recover the information bits as the parity bits are less. While low code rate such as 1/3 it is not able to recover the redundancy bits.
