  • Publication number: 20220303052
    Abstract: An apparatus and system for decreasing packet error rate (PER) in a station (STA) are described. The STA determines that an Extremely High Throughput (EHT) physical layer protocol data unit (PPDU) is to be constructed for transmission and that Low-Density Parity-Check (LDPC) encoding is to be used to encode a data field of the EHT PPDU. In response, the STA constructs the EHT PPDU in accordance with a construction constraint of the data field of the EHT PPDU when a LDPC codeword (CW) size 648 is to be used for the data field of the EHT PPDU. The construction constraint includes using bit level interleaving or preventing use of LDPC CW size 648 for a modulation coding scheme (MCS) that is larger than 256 quadrature amplitude modulation (QAM) or 64 QAM or for all QAMs.
