  • Publication number: 20250016820
    Abstract: Systems, methods, and mechanisms for preemption of non-low latency data within an aggregated medium access control (MAC) protocol data unit (AMPDU), e.g., such as in current and future IEEE 802.11 systems. A wireless device (e.g., an access point or wireless station) may transmit, during an AMPDU, a trigger to receive (TRX) frame. The TRX frame may indicate preemption of non-low latency data intended for a first wireless station with low latency data intended for a second wireless station, e.g., via an acknowledgement policy change. Additionally, the wireless device may be configured to transmit, to the second wireless station, the low latency data within the AMPDU. Further, the wireless device may be configured to receive, after the AMPDU transmission is complete, a multi-block acknowledgement (M-BA) frame from the second wireless station. The M-BA frame and completion of the AMPDU transmission are separated by a short inter-frame space (SIFS).

  • Publication number: 20250016816
    Abstract: A system and method for optimizing power consumption of energy harvesting nodes in a wireless sensor network. In one embodiment, a system includes a network coordinator. The network coordinator includes a wireless transceiver and a controller. The wireless transceiver is configured to provide access to the wireless sensor network. The controller is configured to determine whether a wireless device that is wirelessly communicating with the network coordinator is powered via energy harvesting. The controller is also configured to schedule, based on a determination that the wireless device is powered via energy harvesting, the wireless device to communicate via the wireless sensor network using a priority timeslot of a superframe of the wireless sensor network. The priority timeslot is a timeslot occurring in an initial portion of the superframe.

  • Publication number: 20240422670
    Abstract: A system and method for reducing energy consumption in a wireless network. In one embodiment, a system includes a network coordinator configured to manage access to a wireless network. The network coordinator includes a controller. The controller is configured to define a channel hopping list that specifies on which channel a beacon signal is transmitted in each slot frame of the wireless network. The controller is also configured to set a number of time slots in each slot frame based on a length of the channel hopping list. The controller is further configured to transmit a first beacon signal in each slot frame on a channel specified by the channel hopping list. The number of slots in each slot frame causes the first beacon signal to be transmitted on a same channel in each slot frame.

  • 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.

    Abstract: A method of an initiating station (ISTA) can include transmitting, to a responding station (RSTA), a first indicator indicating whether the ISTA supports one or more optional preamble puncture patterns. Additionally, the method can include receiving, from the RSTA, a second indicator indicating whether the RSTA supports optional preamble puncture patterns. Furthermore and responsive to determining that the ISTA and the RSTA support optional preamble puncture patterns, the method can further include starting, according to at least one of the optional preamble puncture patterns, a ranging session with the RSTA.

  • 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.

  • Publication number: 20240334485
    Abstract: This disclosure relates to methods for transmitting and receiving multi-user request-to-send and clear-to-send frames in a wireless communication system. An access point wireless device may establish wireless connections with multiple wireless devices. The access point wireless device may transmit a multi-user request-to-send frame to the wireless devices. The multi-user request-to-send frame may indicate a transmit opportunity duration and allocate frequency resource units on which to transmit clear-to-send frames to the wireless devices. The wireless devices may transmit the clear-to-send frames on the allocated frequency resource units. The clear-to-send frames can include an indication of partial or full availability for the transmit opportunity.

  • Publication number: 20240314621
    Abstract: Disclosed herein are apparatuses and a method for implementing latency reduction using preemption within a physical layer (PHY) protocol data unit (PDU) (PPDU). An embodiment operates by encoding a multi-user PPDU (MU-PPDU) for transmission, where, the MU-PPDU comprises a plurality of aggregated media access control (MAC) PDUs (A-MPDUs) addressed to respective non-low-latency stations (non-LL-STAs). Based on a determination that low-latency data addressed to a low-latency station (LL-STA) is available for transmission at a MAC layer of the AP, the embodiment then transmits a preemption-indicator signal to the LL-STA and at least one non-LL-STA. Further, the embodiment identifies an A-MPDU of the plurality of A-MPDUs that is scheduled for transmission over a resource unit (RU) designated for transmitting low-latency data.

    Abstract: An electronic device (such as an access point) is described. This electronic device transmits an orthogonal frequency division multiple access (OFDMA) frame to a recipient electronic device (such as a client or a station). The OFDMA frame includes multiple predefined resource units (RUs) allocated to the recipient electronic device in a set of predefined RUs having associated frequency bandwidths. Moreover, the multiple predefined RUs include two or more first predefined RUs having a first number of tones less than a predefined amount, or two or more second predefined RUs having a second number of tones greater than or equal to the predefined amount. For example, the predefined amount may include 242 tones. Note that the multiple predefined RUs may have the same or different numbers of tones. Moreover, the electronic may receive an acknowledgment or a block acknowledgment from the recipient electronic device.
