Abstract: Certain aspects relate to methods and apparatus for traffic separation in a multi AP (MAP) network. In some cases, a MAP Controller may configure sets of SSIDs to a single VLAN ID in a Traffic Separation Policy and distribute the Traffic Separation Policy information to the MAP Agents.

Abstract: This disclosure provides systems, methods and apparatuses for channel selection and channel selection planning in a network including a root AP (RAP) and a number of satellite APs (SAPs). The root AP may assign operating channels for one or more of the satellite APs in a manner that optimizes network performance by considering the impact that each of the satellite APs (as well as their respective client devices) may have on the network. In some implementations, the root AP may provide centralized channel selection planning for the network based a number of network parameters observed by one or more of the satellite APs. The network parameters may include, for example, channel conditions, traffic loads, traffic patterns, service needs of client devices, available channels, and other network utilization information observed by one or more of the satellite APs.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer-readable media, for serving AP selection in a network having multiple access points (APs). In one aspect, a serving AP selection unit can steer a device (such as a client station, STA, or a child AP) based on a quality of service profile (such as a capacity requirement or a delay requirement) of the device. The device may be initially associated with a first AP (as the current serving AP) in the network. The serving AP selection unit may select a second AP as a new serving AP for the device, and cause the device to associate with the second AP rather than the first AP. The selection of a serving AP may take into account delay or hop count in addition to path capacities for various paths in the network.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for enhanced channel selection in a network having multiple access points (APs). The enhanced channel selection may optimize the overall performance of the network by incorporating considerations about the impact on other APs in a big-picture view of the network. In one aspect, enhanced channel selection may combine a first channel selection process at a first AP (based on first channel selection by the first AP) with a second channel selection at a Multi-AP Controller. Coordination between the first AP and the Multi-AP Controller may improve a channel selection technique to optimize channel selection based on considerations of the overall network.

Abstract: Methods, systems, and devices for wireless communication are described for buffer status report triggering. An access point (AP) may identify that an amount of uplink data queued in a buffer of a station is less than a predetermined threshold. The AP may determine that a buffer status report (BSR) trigger condition is satisfied by estimating that the station has data to transmit to the access point, or by identifying that the access point will schedule an uplink transmission for the station. The AP may transmit a BSR trigger to the station based at least in part on identifying that the amount of uplink data queued in the buffer is less than the predetermined threshold and determining that the BSR trigger condition is satisfied.

Abstract: Methods, systems, and devices are described for wireless communications. A communication device may utilize enhanced roaming techniques to dynamically adjust signal strength thresholds in a high density AP environment. For instance, a communication device determines a signal strength of a communication link between a wireless device and an access point (AP). The communication device further compares the signal strength value to at least a low threshold and a high threshold and performs a channel scan for the communication link when the signal strength value is below the low threshold. The communication device also adjusts the low threshold when the signal strength value is greater than the high threshold.

Abstract: As part of a communication session, a wireless source device can transmit audio and video data to a wireless sink device, and the wireless sink device can transmit user input data received at the wireless sink device back to the wireless source device. In this manner, a user of the wireless sink dev ice can control the wireless source device and control the content that is being transmitted from the wireless source device to the wireless sink device. The user input data transmitted by the wireless sink device can be input data obtained at a third party device and forwarded to the wireless source device.

Abstract: Methods, systems, and devices for wireless communication are described. An access point (AP) may win access to an unlicensed frequency channel for a transmission opportunity. For the transmission opportunity, the AP may dynamically schedule a duration of time to be used for uplink transmissions and a duration of time to be used for downlink transmissions. The schedule may be based on a comparison of values for a parameter monitored by the AP. The parameter may be monitored for uplink traffic and for downlink traffic. The parameter may indicate the latency experienced by each direction of traffic, or an intolerance of each direction of traffic to delay. The AP may schedule the uplink and downlink durations to compensate for the discrepancy in latency between the two directions of traffic.

Abstract: A wireless dockee may access a vendor-specific feature available on a peripheral device in communication with a wireless docking center. Information regarding the vendor-specific feature may be communicated by the wireless docking center to the wireless dockee both during pre-association discovery as well as via a service description that corresponds with the vendor-specific feature. The wireless dockee may use the received information to generate an access request to the peripheral device.
