    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.

    Abstract: Systems, methods, and apparatuses for generating variable length block acknowledgement fields in a wireless network are provided. One aspect of this disclosure provides a method of wireless communication. The method includes receiving, by an apparatus, an indication of block acknowledgment (BA) parameters, and determining, by the apparatus, a size of a bitmap field based on the BA parameters. The method further includes generating, by the apparatus, a block acknowledgment (BA) frame comprising the bitmap field and an indication of the determined size of the bitmap field.

    Abstract: Systems, methods, and devices for wireless communication are disclosed herein. One aspect of the disclosure provides a method of transmitting to two or more wireless communication devices. The method includes transmitting a first section of a preamble according to a first format, the first section of the preamble containing information informing devices compatible with the first format to defer to the transmission, transmitting a second section of the preamble according to a second format, the second section of the preamble containing tone allocation information, the tone allocation information identifying two or more wireless communication devices; and transmitting data to the two or more wireless communication devices simultaneously, the data contained on two or more sub-bands.
