RATELESS POLAR CODES - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240313887 titled 'RATELESS POLAR CODES
The abstract describes methods, systems, and devices for wireless communication. A first wireless device transmits a codeword to a second wireless device, which decodes the codeword using a polar code and log likelihood ratios (LLRs). If the second device fails to decode some information bits, the first device retransmits a subset of the bits independently of the polar code. The second device then attempts to decode the codeword again using a combination of the original LLRs and the new LLRs for the subset.
- Wireless communication system utilizing polar codes for encoding information bits
- Adaptive retransmission of information bits based on decoding failures
- Combination of LLRs from initial decoding attempt and retransmitted bits for improved decoding accuracy
- Efficient error correction mechanism in wireless communication
- Enhanced reliability and performance in wireless data transmission
Potential Applications: - Mobile communication networks - Internet of Things (IoT) devices - Satellite communication systems - Wireless sensor networks - 5G and beyond wireless technologies

Original Abstract Submitted
methods, systems, and devices for wireless communication are described. a first wireless device may transmit, to a second wireless device, a codeword corresponding to a set of information bits encoded using a polar code, and the second wireless device may obtain a first set of log likelihood ratios (llrs) based on performing a first decoding operation on the codeword. in cases that the first wireless device identifies a failure of the second wireless device to decode one or more of the information bits, the first wireless device may retransmit a subset of the information bits to the second wireless device independently of the polar code. the second wireless device may then attempt to decode the codeword a second time using the polar code and based on a combination of a first set of llrs and a second set of llrs corresponding to the subset of the information bits.
