  • Publication number: 20240129724
    Abstract: An apparatus of an access point multi-link device (AP MLD) is configured as a Transmitted Basic Service Set Identifier (TxBSSID) in a wireless network including a multiple BSSID (MBSSID) set. The apparatus includes memory and processing circuitry coupled to the memory and configured to encode beacon frames for transmission to non-AP MLDs in the wireless network. The transmission is on behalf of the TxBSSID and Non-Transmitted BSSIDs (NonTxBSSIDs) within the MBSSID set. A link recommendation frame is encoded for transmission to the non-AP MLDs. The link recommendation frame includes link recommendations for the non-AP MLDs associated with any APs in the MBSSID set. A group management cipher suite of the TxBSSID is used to protect the link recommendation frame encoded for the transmission.

  • Publication number: 20240129951
    Abstract: An apparatus of an access point (AP) includes memory and processing circuitry configured to encode a trigger frame for transmission to a plurality of station devices (STAs) in a wireless network. A first request frame received from a STA of the plurality of STAs is decoded. The first request frame requests the AP to create a protected period for the STA when the STA is in an exposed node situation. A second request frame is encoded for transition to at least a second AP. The second request frame requests the at least second AP to establish a restricted target wake time (rTWT) for the STA. A first response frame from the at least second AP is decoded. The first response frame includes an indication of whether the rTWT is established. A second response frame is encoded for transmission to the STA. The second response frame includes the indication.

  • Publication number: 20240090025
    Abstract: For example, an Access Point (AP) may be configured to transmit a frame including a prioritized-access enabled/disabled field to indicate whether a prioritized-access contention mechanism is to be enabled or disabled over a wireless medium. For example, the prioritized-access contention mechanism may be configured to allow a prioritized station (STA) to transmit a reservation signal over the wireless medium at a reservation signal transmission time, and to contend the wireless medium according to a high-priority contention policy to obtain a Transmit Opportunity (TxOP) after transmission of the reservation signal. For example, the reservation signal transmission time may be based on an end of a predefined time duration from a start of a contention period. For example, the reservation signal may be configured to indicate a busy Clear Channel Assessment (CCA) to a receiving STA.

  • Publication number: 20240080895
    Abstract: For example, an Access Point (AP) may be configured to configure a trigger frame to indicate an allocation of a triggered contention-based period to be allocated within a Transmit Opportunity (TxOP) of the AP. For example, the trigger frame may be configured to indicate that only one or more eligible non-AP stations (STAs), which are eligible to communicate during the triggered contention-based period, are to be allowed to contend a wireless medium during the triggered contention-based period. For example, the AP may be configured to transmit the trigger frame to initiate the allocation of the triggered contention-based period. For example, a non-AP STA may be configured to be allowed to contend the wireless medium for a transmission during the triggered contention-based period, for example, based on a determination that the non-AP STA is to be defined as an eligible non-AP STA for the triggered contention-based period.

  • Patent number: 11924866
    Abstract: Embodiments of an Extremely High Throughput Station (EHT STA) (STA1) configured for operating in a next-generation (NG) wireless local area network (WLAN) are described herein. In some embodiments, the EHT STA encodes a common signal field (SIG) (Coex-SIG) of an EHT PPDU to include a TXOP duration field. The TXOP duration field is more than seven bits to indicate an actual TXOP duration of a transmission from the EHT STA comprising the EHT PPDU transmitted to a second station (STA2). Decoding the TXOP duration field of the EHT PPDU by a third-party station (STA4) causes the third-party station (STA4) to defer a transmission until after an end of the transmission from the second station (STA2).
