摘要： 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.

摘要： 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.

摘要： Methods, systems and apparatuses for managing roaming by access points (AP), a controller, and a wireless device are described. The wireless device can indicate intent to roam from a source AP to a target AP. The wireless device, APs, and controller can adjust delivery of uplink and/or downlink data in association with the roam.

摘要： Methods, systems and apparatuses for managing roaming by access points (AP), a controller, and a wireless device are described. The wireless device may indicate intent to roam from a source AP to a target AP. The wireless device, APs, and controller may adjust buffering in anticipation of the change. The wireless device, APs, and controller may deliver buffered data via the target AP following a successful change from the source AP.

摘要： A method and apparatus of a device that manages a video telephony call is described. In an exemplary embodiment, the device receives a network event from a network service of a device. The device further determines that the network event that is due to a local disruption of a network component of the device. In addition, and in response to the determination, the device restricts a local dynamic control of the video telephony call.
