Abstract
This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for implementing a retransmission protocol in a wireless local area network (WLAN). The retransmission protocol enables a sending station (STA) to communicate additional parity bits associated with an original transmission that included forward error correction (FEC) encoded codewords. Several techniques are described for a receiving STA to indicate which portions of the original transmission was not properly received. The receiving STA may store the original transmission for use with additional parity bits in a subsequent transmission. The sending STA may communicate the additional parity bits in a subsequent transmission to assist the receiving STA recover the data from the original transmission.
