  • Publication number: 20230412435
    Abstract: A wireless device may use 2.5 MHz narrow band channel spacing. In some embodiments, clear channel assessment based listen before talk may be used to determine if a channel is idle or busy. In some embodiments, randomized channel access may be achieved using a pseudo random number generator on an allowed list of channels. In some embodiments, an avoid loitering mechanism may be employed to reduce interference with transmitters using the same frequency bands.

  • Patent number: 11805558
    Abstract: This disclosure provides methods, devices and systems for synchronized channel access. Some implementations more specifically relate to facilitating coexistence among wireless communication devices that support synchronized channel access and those that do not. A group of access points may schedule periodically recurring, synchronized channel access periods by periodically transmitting quiet elements. The quiet elements establish recurring quiet periods during which legacy devices are not permitted to transmit. In some implementations, an access point may transmit one or more quiet override elements each associated with a respective quiet element and indicating to other access points supporting synchronized channel access that they are permitted to contend for access during the respective quiet period.

  • Patent number: 11800467
    Abstract: This disclosure provides systems, methods, apparatus, including computer programs encoded on computer storage media for orthogonal multiplexing of high efficiency (HE) and extremely high throughput (EHT) wireless traffic. Devices in a wireless local area network (WLAN) may operate under HE or EHT conditions. An access point (AP) may support both HE and EHT communications with WLAN devices. To enable substantially simultaneous downlink HE and EHT transmissions and substantially simultaneous uplink HE and EHT transmissions, the AP may support orthogonal frequency-division multiple access (OFDMA) of HE and EHT transmissions. For example, pre-HE and pre-EHT modulated fields, HE and EHT modulated fields, and payloads may be aligned in time for the HE and EHT transmissions. The AP may ensure orthogonality for multiplexing the HE and EHT transmissions based on the alignment. In some implementations, a trigger frame may be utilized to indicate uplink transmission alignments.

  • Publication number: 20230337227
    Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for managing uplink access in a wireless local area network. A station (STA) may inform an access point (AP) of uplink quality of service (QoS) parameters for a traffic flow from the STA. The AP may control uplink resources to satisfy the QoS parameters. For example, the AP may select from among different access modes (including a single user (SU) access mode, an uplink multi-user (UL-MU) scheduled access mode, a multi-user enhanced distributed controlled access (MU EDCA) access mode, or a low latency (LL) access mode). The AP may cause the STA to use a SU access mode or the LL access mode if the UL-MU scheduled access mode and the MU EDCA access mode are not sufficient to satisfy the uplink QoS parameters for the traffic flow.

  • Patent number: 11784746
    Abstract: An electronic device (such as an access point) that receives one or more block acknowledgments is described. This electronic device may transmit an extremely high-throughput (EHT) physical layer convergence protocol (PLCP) protocol data unit (PPDU) to a recipient electronic device, where the EHT PPDU is transmitted in multiple non-contiguous sub-bands that are separated by a punctured sub-band. Moreover, the electronic may receive the one or more block acknowledgments from the recipient electronic device, where the one or more block acknowledgments exclude the punctured sub-band. Note that the EHT PPDU may exclude transmitted energy in the punctured sub-band. Moreover, the punctured sub-band may have a bandwidth of at least 20 MHz and may be different from a primary sub-band.
