Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: In order to reduce the power consumption associated with waking and receiving beacons, a current listening device in a group of electronic devices wakes and scans for a beacon from another electronic device (such as an access point) using a wireless-local-area-network (WLAN) communication protocol (such as Wi-Fi®). Then, the current listening device transmits information associated with the beacon to the group of electronic devices using a second communication protocol (such as Bluetooth® Low Energy), which is different than the WLAN communication protocol and has a lower power consumption. Moreover, the current listening device receives, using the second communication protocol, a sequence of responses from the group of electronic devices indicating that the information was received, wherein the responses from different electronic devices are received at different times. For example, the responses may be received in a predefined order and/or in round-robin fashion for the group of electronic devices.
