Abstract: Systems and methodologies are described that facilitate supporting mobility for UEs and relay eNBs in split-cell relay configurations. Parameters regarding communicating with one or more UEs can be provided to disparate eNBs from a donor eNB to provide mobility for one or more of the UEs or a serving relay eNB. In addition, a donor eNB can request establishment of one or more radio bearers at a target relay eNB for continuing communications with one or more UEs. Moreover, a donor eNB can provide information regarding one or more core network bearers to a target donor eNB to facilitate establishing the core network bearers at the target donor eNB for communicating with the one or more UEs. Furthermore, uplink buffer contents from a relay eNB can be provided to a target donor eNB so communications from the one or more UEs can be continued by the target donor eNB.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for adjusting a packet duration for triggered uplink (UL) transmissions to an access point (AP) from one or more stations (STAs). In one aspect, the AP may estimate an amount of data that a STA has queued for UL transmission and select the packet duration based on the estimated amount of queued UL data. The AP may transmit a trigger frame that solicits UL data from the STA and indicates the selected packet duration. In response, the AP may receive an UL packet from the STA and determine an amount of UL data queued in the STA based on the UL packet. In some implementations, the AP may selectively adjust the packet duration for UL transmissions based on the UL packet, the determined amount of UL data queued in the STA, or both.

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 device 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: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer-readable media, for steering an association of a device in a network having multiple access points (APs). In one aspect, a first AP can obtain per-AP metric information regarding a plurality of other APs in the network. The per-AP metric information may include backhaul performance information regarding at least one wireless backhaul channel in the network. The per-AP metric information may include an estimated air time fraction value reported by the other APs. A selection to steer the device from the first AP to a second AP can be based, at least in part, on the per-AP metric information. In some implementations, a Multi-AP Controller can redistribute per-AP metric information collected from multiple APs in the network. In some implementations, a topology of the network may be optimized by steering a child AP to another wireless backhaul link.

Abstract: Methods, systems, and apparatuses are described for wireless communications. More particularly, an access point (AP) identifies a plurality of multi-user multiple-input multiple-output (MU-MIMO) groups associated with a wireless station (STA). The AP determines a communication metric associated with each of the plurality of MU-MIMO groups. The communication metric provides an indication of the compatibility of the STAs in the MU-MIMO group. The AP prioritizes at least one of the plurality of MU-MIMO groups based at least in part on the communication metric associated with the prioritized MU-MIMO group. The AP creates a preferred group list and/or a blacklisted group list and included the prioritized MU-MIMO group in the appropriate group list.

Abstract: Methods, systems, and devices are described for wireless communications. A communication device may utilize enhanced roaming techniques to use multiple channel maps for a high density AP environment. For instance, a communication device performs at least a partial channel scan by a communications device while the communications device is connected to an access point (AP) associated with a basic service set identifier (BSSID). The communication device further selects a channel map from a plurality of channel maps associated with the BSSID based at least in part on the partial scan, wherein each of the channel maps associated with the BSSID comprises a different set of signal strength measurements for a same set of neighboring APs. The communication device also uses the selected channel map as a basis for a roaming operation by the wireless device.

Abstract: In one example, a method includes determining, by a wireless dockee (WD), one or more wireless docking environments (WDNs) associated with a wireless docking center (WDC), wherein each WDN of the one or more WDNs corresponds to at least one peripheral function (PF) of one or more PFs that are each associated with the WDC. In this example, the method also includes wirelessly accessing, by the WD, a respective at least one PF corresponding to a particular WDN of the one or more WDNs associated with the WDC.
