A bit representation of the availability or unavailability of a plurality of sub-bands of a portion of frequency spectrum is generated and included in a physical layer protocol data unit, which is transmitted to a target station to allocate resource units within the portion of frequency spectrum for use by the target station. The sub-bands may be 20 MHz spectrum sub-bands for large-size resource units, or the portion of frequency spectrum may be a single 20 MHz band sub-divided into multiple sub-bands for allocating small-size resource units. A station that receives the data unit may decode the bit representation and use the allocated resource units to communicate over the wireless local area network.

  • METHOD AND APPARATUS FOR PRIORITY TRANSMISSION OF WLAN FRAMES
    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.
