Patent ID: 11134493

Abstract:
A method for Wireless Local-Area Network (WLAN) communication in a WLAN device includes generating a WLAN transmission including first bits, by at least (i) encoding the first bits with a Forward Error Correction (FEC) code to produce first encoded bits, and (ii) scrambling the first encoded bits with a first scrambling sequence. The WLAN transmission is transmitted from the WLAN device to a remote WLAN device. In response to receiving from the remote WLAN device an indication that reception of the WLAN transmission has failed, a WLAN retransmission including second bits is generated. Generating the retransmission includes (i) obtaining second encoded bits, which include the second bits encoded with the FEC code, and (ii) scrambling the second encoded bits with a second scrambling sequence that is different from the first scrambling sequence. The WLAN retransmission is transmitted from the WLAN device to the remote WLAN device.
