    Abstract: Various aspects are provided for wireless communication channel management. For instance, aspects of an example method are provided, the method including detecting a trigger condition for changing an operating frequency of a wireless communication link between a first device and a second device. In addition, the example method may include obtaining a target operating frequency for the wireless communication link based on detecting the trigger condition. Moreover, the example method may include tuning a transceiver to the target operating frequency. In an example, the first device may be an unmanned aerial vehicle (UAV) and the second device may be a controller associated with the UAV. Additionally, example apparatuses and computer-readable media are provided for wireless communication channel management, the example apparatuses and computer-readable media being configured to perform, or store computer-executable code to perform, the disclosed example methods.

    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for low-latency communications in wireless networks. In some implementations, a wireless station (STA) may transmit a data session request to a root access point (AP) in a wireless network responsive to activating an application associated with latency restricted (LR) data traffic. In some aspects, the data session request may indicate one or more preferred channels to carry the LR data traffic. In some other aspects, the data session request may indicate one or more preferred times to exchange the LR data traffic. In some implementations, the root AP may establish an LR data path with the STA based on the preferred time or frequency resources indicated in the data session request. The LR data path may include time or frequency resources that are reserved for LR data traffic between the root AP and the STA.

    Abstract: This disclosure provides systems, methods and apparatus for asynchronous channel access control of a wireless system. In some aspects, a device may adjust the priority of one or more PPDUs and may perform other operations to ensure control of a wireless medium at certain times while still allowing for other devices to communicate on the wireless medium. For example, the device may adjust a backoff counter or one or more EDCA parameters to ensure obtaining control of the wireless medium to transmit a first PPDU of an application file. For one or more subsequent PPDUs of the application file, the device may again adjust a backoff counter or one or more EDCA parameters to allow other devices to obtain control of the wireless medium in certain scenarios (such as a second device to provide information back to the device or to otherwise transmit using the shared wireless medium).

    Abstract: Methods and apparatuses for communicating in a wireless communication network are disclosed. For example, one method includes determining, by a first access point, a polling schedule for communicating with one or more wireless stations on a first wireless communication channel, the polling schedule for a second access point on a second wireless communication channel. The method further includes transmitting, by the first access point, on the first wireless communication channel, transmission information to the one or more wireless stations, wherein the transmission information comprises information for the one or more wireless stations to receive a transmission from the second access point on the second wireless communication channel. The method further includes transmitting, by the first access point, on the first wireless communication channel, one or more packets to at least one of the one or more wireless stations in accordance with the polling schedule.

    Abstract: Methods, systems, and devices are described for wireless communication. A wireless device, such as a station or an access point, may transmit a first out-of-band signal and may update a first list of neighboring devices based on receiving a second out-of-band signal from the neighboring devices. The device may exclude some neighboring devices from the first list based on the received signal strength indicator or the operating band of the neighboring device. The device may receive, from one or more associated peers, a second list of neighboring devices to the associated peer. The device may then compare its neighbor list to the neighbor list of its associated peer, and may identify additional neighbors in the associated peer's list that are unlisted in its own neighbor list, where the additional neighbors may operate on an overlapping channel. Based on the comparison, the device may change an operation mode before transmitting.

    Abstract: A method of operating a station (STA) in a communications network is disclosed. A set of access categories of the STA that are enabled for unscheduled automatic power save delivery (U-APSD) are identified. Specifically, each access category in the set of access categories is associated with one or more user priority values. A lowest-priority access category is determined among the set of access categories. Specifically, the lowest-priority access category is associated with the lowest user priority value among the set of access categories. A trigger frame associated with the lowest-priority access category is then transmitted to an access point (AP) to initiate a first unscheduled service period with the AP.

    Abstract: A hybrid device may select a next hop for a packet stream based upon a path selection. The path selection includes calculating end-to-end path capacity for candidate paths to a destination device. End-to-end path capacity is calculated based upon contention groups of particular links in at least one of the plurality of paths. Selected paths are recorded in a stream forwarding table for use with subsequent packets of a packet stream. In some embodiments, each hybrid device independently performs path selection logic or path update logic for a packet stream.
