Abstract: In the IEEE 802.11be standardization activities, application of wireless LAN communication technologies to an application requiring high reliability and low latency such as a Time Sensitive Network (TSN) has also been considered as a standardization target range.

In a case that a configuration of the retransmission scheme indicates a Hybrid Auto Repeat reQuest (HARQ), the physical layer frame generator encodes, at a prescribed coding rate, a Low Density Parity Check (LDPC) information block including information bits to generate a parity bit sequence, and divides the parity bit sequence into blocks the number of which is given by a coding rate indicated by a Modulation and Coding Scheme (MCS), to generate multiple parity blocks. Each of the parity blocks is associated with the number of retransmissions. The codeword is generated based on the information bits and one of the parity blocks.
