  • Patent number: 11882596
    Abstract: Embodiments of the present invention are drawn to electronic systems that perform EHT operations for a wireless network supporting a 160+160 MHz/320 MHz operating mode. RTS/CTS frame exchange sequences and TXOP truncation can be performed using punctured preambles according to subchannels indicated in a bitmap subfield (e.g., an Allowed Bitmap Subfield). Preamble puncturing is supported for EHT PPDUs transmitted to multiple STAs using MU-RTS/MU-CTS frames transmitted in non-HT duplicate PPDUs. Preamble puncturing is also supported for an EHT PPDU transmitted to a single STA. The RTS and CTS frames can be sent in a non-HT duplicate PPDU with preamble puncturing, for example.

  • Patent number: 11882625
    Abstract: Embodiments of the present invention are drawn to electronic systems capable of transmitting a group addressed frame that identifies an MLD according to an MLD MAC address. The group addressed frame can include an ARP request, for example, and can be transmitted by an AP MLD responsive to an individually addressed frame transmitted by a non-AP STA MLD associated with the AP MLD. The AP MLD can provide a proxy ARP service for associated non-AP STA MLDs.

  • Patent number: 11882598
    Abstract: An apparatus (e.g., an access point (AP)) announces to one or more stations (STAs), in a frame, one or more preamble detection (PD) channels in a frequency segment such that each of the one or more STAs monitors a respective one of the one or more PD channels to detect any transmission on the one or more PD channels. The apparatus then wirelessly communicates with at least one of the one or more STAs on one of the one or more PD channels during a transmission opportunity (TXOP).

  • Patent number: 11877321
    Abstract: A multi-link device (MLD) monitors each of first and second links in a multi-link operation in wireless communications, with the first link being a primary link and the second link being a secondary link. The MLD obtains a transmission opportunity (TXOP) on one of the first link and the second link as a result of performing a contention-based channel access on the first link and the second link. The MLD checks channel status of the other of the first link and the second link. The MLD then transmits one or more frames on the first link but not on the second link, on the second link but not on the first link, or on both the first link and the second link synchronously, responsive to the channel status of the other link given the TXOP being obtained on the one of the first link and the second link.
