    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: 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: 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: A first powerline communication device, associated with a first powerline communication network, determines a plurality of time intervals in a beacon period of the first powerline communication network based, at least in part, on variations in levels of interference from a second powerline communication network which shares a powerline communication medium with the first powerline communication network. The first powerline communication device determines at least one channel adaptation parameter for each of the plurality of time intervals in the beacon period to compensate for effects of the variations in the levels of interference from the second powerline communication network. The first powerline communication device applies the at least one channel adaptation parameter corresponding to one or more of the plurality of time intervals in the beacon period when transmitting data via the powerline communication medium.
