An access point transmits a trigger frame to a set of electronic devices in a wireless local area network (WLAN). The access point receives, from one or more electronic devices in a set of electronic devices, one or more requests to send data. In response, the access point transmits the trigger frame, which includes information specifying an ordered list of electronic devices in the set of electronic devices that are allowed to transmit. Subsequently, the access point sequentially receives one or more frames from the ordered list of electronic devices. After receiving a frame from the last electronic device in the ordered list of electronic devices or after an unused transmit opportunity of the last electronic device in the ordered list of electronic devices, the access point transmits a block acknowledgment to the ordered list of electronic devices.

Triggered wireless access protocol

This disclosure relates to wireless communication techniques. According to some embodiments, a wireless device may select a random number and sequentially advertise the bits of the random number. If the wireless device advertises the highest random number, it may proceed to transmit a packet using a channel. If another device advertises a higher number, the wireless device may not transmit its packet and may restart the process.

Enhanced Wi-Fi access protocol (EWAP)

An electronic device may coordinate access to a shared communication channel with one or more other electronic devices. After receiving frames from the one or more other electronic devices with information specifying back-off values associated with at least an access category for the one or more other electronic devices in a subsequent potential slot transmission opportunity, the electronic device may update a stored list of known occupied back-off values for the subsequent potential slot transmission opportunity. Then, the electronic device may select and may transmit to the one or more other electronic devices an available back-off value for the electronic device in the subsequent potential slot transmission opportunity that is not included in the stored list and that is associated with an access category. Next, during a slot corresponding to the selected back-off value, the electronic device may transmit a second frame to at least another electronic device.
