  • Publication number: 20240380518
    Abstract: Some aspects of this disclosure include an apparatus, method, and computer program product for wireless local area network (WLAN) link adaptation. Some aspects of this disclosure include fast feedback (FB) contents to improve WLAN link adaptation that can address the challenges of ultra-high reliability (UHR) wireless communications. Fast FB contents can include a feedback sequence number (FBSN) that identifies a reference packet and FB data corresponding to the receipt of the reference packet by the receiving device. The FB data can include link adaptation parameters corresponding to the receiving device that the transmitting device can use to adjust (e.g., adapt) subsequent transmissions to the same receiving device. Some aspects include an indicator that informs a receiving device whether to provide a Negative Acknowledgement (NACK) frame (e.g., control packets) with FB contents or not.

  • Publication number: 20240380519
    Abstract: Some aspects of this disclosure include an apparatus, method, and computer program product for wireless local area network (WLAN) link adaptation for multi-user transmission. For example, a receiving device can receive a multi-user-physical layer (PHY) protocol data unit (MU-PPDU) including a preamble and a plurality of data portions. The preamble can include a PHY multi-user-block acknowledgement request (MU-BAR) frame indicating a frequency band for transmitting a trigger-based (TB)-PPDU. The receiving device can decode at least a portion of a first data portion of the and transmit the TB-PPDU including feedback (FB) data corresponding to the first data portion in the frequency band. Even if the decoding of the first data portion fails, the receiving device can use information in the PHY MU-BAR frame to transmit a TB-PPDU to the transmitting device that includes a negative acknowledgment (NACK) frame and a FB sequence number of the MU-PPDU.

  • Patent number: 11184737
    Abstract: A wireless access device is provided that includes at least one processor, an antennae, and a localization engine. The localization engine is executable by the at least one processor to determine a location of the access device, receive a wireless signal from a particular device that includes presence information corresponding to the particular device that lacks self-localization functionality, and determine a location of the particular device based on the location of the access device and the presence information.
