  • Publication number: 20210235319
    Abstract: An extremely high-throughput (EHT) station (STA) is configured for transmission of a control response frame for rate selection. In response to a frame carried in an EHT PPDU soliciting a control response frame, the EHT STA may calculate a duration of a non-HT PPDU containing the control response frame sent at a primary rate. The EHT STA may also encode a high-efficient (HE) single-user (SU) PPDU (HE SU PPDU) for transmission to carry the solicited control response frame when a transmit time of the encoded HE SU PPDU is less than the calculated duration of the non-HT PPDU, or encode an EHT PPDU for transmission to carry the solicited control response frame when a transmit time of the encoded EHT PPDU is less than the calculated duration of the non-HT PPDU. A reduction in overhead may be achieved by using an HE SU PPDU or an EHT PPDU instead of a non-HT PPDU to carry a solicited control response frame.

  • Publication number: 20210185607
    Abstract: Multi-link device (MLD) parameters and security capability indications are described. Each link between an AP MLD and a non-AP MLD is between an AP of the AP MLD and a corresponding STA of the non-AP MLD. Each STA provides a listen and WNM sleep interval. The listen intervals are the same and are converted by the AP MILD into units of the maximum beacon frame interval among the APs to determine whether a STA is awake to receive a particular beacon. Each beacon frame interval and DTIM interval is independent of each other beacon frame internal and DTIM interval. The WNM sleep intervals are in units of the DTIM interval for independent WNM sleep intervals or a smallest DTIM interval among the APs when each WNM sleep interval is the same. A RSNXE in each beacon frame provides an identification of the AP and security capability of the AP.

  • Publication number: 20210144752
    Abstract: An extremely high throughput (EHT) station (STA) configured for trigger based (TB) transmission may decode an trigger frame (TF) received from an access point (AP). The TF may include an assignment of resources comprising one or more 20 MHz channels. The EHT STA may determine which of the one or more assigned channels are available for transmission and which of the allocated channels are unavailable when the EHT STA is assigned more than one 20 MHz channel. The EHT STA may encode a EHT TB PPDU in response to the trigger frame. The EHT TB PPDU may be encoded to include an EHT preamble followed by a data field. The EHT preamble may be encoded to indicate channel availability. The EHT STA may generate signaling to cause the EHT STA to transmit the encoded EHT TB PPDU only on the assigned channels that have been determined to be available.
