摘要： An access point (AP) may operate as a master AP (AP1) to perform multi-AP coordinated beamforming (CBF). The AP1 may to initiate a first sounding sequence with one or more STAs associated with the AP1 (BSS STAs) and the one or more STAs associated with a second AP (AP2) (OBSS STAs). In these embodiments, initiation of the first sounding sequence triggers the AP2 to join the sounding sequence to initiate a second sound sequence with the BSS STAs and the OBSS STAs.

摘要： 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.

摘要： An access point (AP) configured for multi-AP coordinated beamforming (CBF) and multi-AP joint transmission (JT) in an Extremely High Throughput (EHT) wireless local area network (WLAN), when operating as a master AP (AP1) in a multi-AP network, is configured to encode a null data packet announcement (NDPA) frame for multi-AP channel sounding. The NDPA is configured for transmission to a second AP (AP2) and a plurality of stations (STAs) of an EHT group. The NDPA may be encoded to have an information field indicating whether a sounding sequence type is for JT channel sounding or CBF channel sounding. The NDPA may further be encoded to include fields identifying the APs participating in the channel sounding. In these embodiments, the channel sounding sequence for JT can be reused for the channel sounding on CBF.

摘要： This disclosure describes systems, methods, and devices related to long packet extension signaling. A device may calculate a residual value based on a duration of a packet extension, a transmit time, and a signal extension time. The device may generate one or more data symbols of a frame to be transmitted to a station device (STA). The device may compare the residual value to a duration of a first data symbol of the one or more data symbols. The device may include a packet extension dis-ambiguity value to the frame based on the comparison. The device may cause to send the frame to the STA.
