Abstract: Methods, systems, and devices are described for wireless communication. A wireless device may detect a delay in reverse link throughput. The wireless device may reduce the delay by modifying channel access parameters. In one aspect, the wireless device may adjust enhanced distributed channel access (EDCA) parameters. For example, the wireless device may modify contention window size (CW) and arbitration interframe spacing (AIFS). In some cases, the wireless device may instigate EDCA parameter adjustments in another wireless device in the wireless system (e.g., by sending an EDCA adjustment request message). The channel access adjustments may be triggered by detection of various conditions that are indicative of the reverse link delay. For example, the wireless device may monitor the communication of acknowledgments (ACKs) and adjust EDCA parameters if the ACKs are delayed. In other cases, the wireless device may adjust EDCA parameters based at least in part on multi-user (MU) communications.

Abstract: Methods, systems, and devices are described for wireless communications. A device may utilize enhanced roaming techniques to identify a candidate channel for roaming. In one example, a device determines whether a candidate channel is congested by calculating a congestion metric associated with traffic over the shared channel. In some examples, the congestion metric is calculated based at least in part on an amount of energy measured over the candidate. For instance, the calculated congestion metric can be an instantaneous congestion level measured during a CCA. The device may then determine whether to roam to the candidate channel based at least in part on the calculated congestion metric.

Abstract: Methods, devices, and computer-readable media for wireless communication may involve techniques for managing multi-user (MU) operation when a device in a wireless network has coexisting radios. Such techniques may involve identifying a change in a multiple radio access technology (RAT) coexistence status of a first device, e.g., a change between a coexistence status that is not disruptive to MU communications and one that is disruptive. For a device communicating with a network using Wi-Fi, the change in the multiple RAT coexistence status may indicate a change between inactive Bluetooth (BT) communications and active BT communications concurrent with Wi-Fi communications. Based at least in part on the identified change in the multiple RAT coexistence status, a MU communications operation at a second device may be adjusted, for example, by disabling MU communication between the first and second devices over a first RAT when the first device changes to a coexistence status that may disrupt MU communications.

Abstract: An extensible hub is disclosed for providing multi-hop wireless communication among universal serial bus (USB) devices, for example, utilizing a WiGig Serial Extension (WSE) air interface. The extensible hub may include a device protocol adaptation layer (PAL), as well as a host PAL, and further a bridge for providing a data flow path between the device and host PALs. The bridge may be configured to distinguish between request messages and response messages in accordance with a header on those messages. Further, the extensible hub may include virtual ports and may map device handles and endpoint handles to provide for routing of messages to the correct downstream devices in a multi-hop network tree.

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.
