Abstract: A non-access point (AP) station (STA) may be configured for receipt of a multi-user physical layer protocol data unit (MU-PPDU) with network coding. The STA may decode at least portions of a MU-PPDU received from an access point (AP). The MU-PPDU may comprise a first data portion addressed to the STA, a second data portion addressed to a second STA2, and a parity portion addressed to both the stations. The parity portion may be generated by the AP based on a network coding of the first and second data portions. When the first data portion is received by the STA with errors, the STA may attempt to recover the first data portion using both the parity portion and the second data portion.

Abstract: The present disclosure is related to multi-access traffic management in multi-access computing environments. A reliability enhancement engine (REE) operated by a multi-access multipath traffic manager identifies traffic flows that have high reliability requirements (“reliability flows”) and performs admission control for the reliability flows. The REE determines a coding rate (e.g., a redundancy factor) and traffic distribution strategies for the identified reliability flows. The REE applies cross-access network coding (NC) on the reliability flows, and handles multi-access acknowledgements and traffic pacing, which may involve multiplexing traffic of the reliability flows with non-high-reliability traffic. Other embodiments may be described and/or claimed.
