Samsung patents new way to pack error-checking bits into 5G and 6G data
Samsung describes a method for sending data over 5G or 6G networks that mixes error-checking bits with actual data before transmission. The system uses a specific pattern to shuffle these bits together, then applies two types of coding to create a final signal that is sent to the receiver.
In the filing’s own words
The present disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). A method performed by a transmitting node in a wireless communication system may include encoding a plurality of information bits using a plurality of cyclic redundancy check (CRC) bits, interleaving the plurality of the information bits and the plurality of the CRC bits using an interleaving pattern, generating a codeword by convolution-encoding and polar-encoding the plurality of the interleaved information bits and the plurality of the interleaved CRC bits, and transmitting the codeword to a receiving node. The interleaving pattern may correspond to a matrix generated based on a size of the plurality of the information bits and a size the plurality of the CRC bits.
What exactly they claim (claim 1)
1. A method performed by a transmitting node, the method comprising: encoding information bits by concatenating cyclic redundancy check (CRC) bits to a last information bit of the information bits; identifying a matrix mapped with a size of the information bits and a size of the CRC bits, wherein the matrix includes a first sub matrix corresponding to an identity matrix and a second sub matrix; identifying, for each column of the second sub matrix, first row indices in which 1 is located; generating an interleaving pattern by sequentially adding, for each column of the second sub matrix, second row indices that are not previously added among the first row indices; interleaving, based on the interleaving pattern, the information bits and the CRC bits; generating a codeword by performing a convolution-encoding and a polar-encoding on the interleaved information bits and the interleaved CRC bits; and transmitting the codeword to a receiving node.
