The field of polar coding is moving towards addressing the increasingly stringent performance requirements of ultra-reliable low-latency communication (URLLC) in 6G scenarios. Researchers are exploring novel coding schemes and decoding methods to reduce latency while guaranteeing reliability. Notably, the use of spatiotemporal 2-D polar codes and linear decoding techniques are being investigated to fully exploit the large spatial degrees of freedom in massive MIMO systems. These developments have the potential to provide capacity-achieving and latency-efficient channel coding solutions for future URLLC scenarios. Noteworthy papers include: Performance Analysis of Spatiotemporal 2-D Polar Codes for Massive MIMO with MMSE Receivers, which proposes a novel 2-D polar coding scheme that can significantly reduce latency while guaranteeing reliability. Polar Coding and Linear Decoding, which explores linear decoding at a first or single trial in the case of small losses or small number of bit-flipping, and repeated transmission for medium level losses.
