Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for a first wireless device to select a channel to a second wireless device among a set of channels to the second wireless device shared by a set of wireless devices of the wireless network, and further transmit data to the second wireless device over the selected channel. The first wireless device can perform a measurement to determine a channel occupancy during a measurement period for a channel, wherein the measurement period includes a plurality of periodic transmission durations. The first wireless device can select a channel that is less occupied indicated by the channel occupancy of the channel. The first wireless device can further transmit data to the second wireless device over the selected channel in a transmission period after the measurement period.

Abstract: Methods for scheduling data packets based on a target transmission time may include receiving, from an application layer at a first time, a data packet and an associated latency requirement. The first layer may determine based, at least in part, on the associated latency requirement, a target transmission time. The target transmission time may be a sum of a queuing delay, an expected transmit completion time, and the first time. The data packet may be queued (or scheduled for transmission) based, at least in part, on the target transmission time and an access category assigned to the data packet. The data packet may be transmitted (or scheduled for transmission) from the queue according to the target transmission time. The expected transmit completion time may be a sum of an average contention time for the access category assigned to the data packet and estimated airtime.

Abstract: Methods, systems, and apparatus are presented for providing enhanced scheduling requests, e.g., in an IEEE 802.11 network. A client station (STA) may determine one or more minimum quality of service (QoS) metrics for supporting an application being implemented by the STA, and may determine minimum scheduling parameters to be implemented by an access point (AP) to achieve the minimum QoS. The STA may transmit to the AP a specific scheduling request indicating the minimum scheduling parameters. In response, the AP may schedule communication resources for the STA in accordance with the minimum scheduling resources.
