  • Publication number: 20210289552
    Abstract: Aspects of the present application provide mechanisms for minimizing latency in real time application (RTA) traffic on wireless LANs. A wireless electronic device identifies real time application network packets in the Application layer, gives them a novel MPDU frame type and subtype, and maps them into a high priority access category such as AC_VO. Upon receiving a TXOP, the device preferentially transmits RTA frames before frames mapped to the access category awarded the TXOP. Additional aspects allow for pre-emptive priority transmission of RTA frames.
