Abstract: Methods, systems, and devices for wireless communication are described. A wireless device (e.g., an access point or a station) capable of supporting multiple chain configuration modes may monitor traffic on a wireless channel. The wireless device may, based on the monitoring, determine a series of values for a metric that is indicative of communication conditions. The metric may be a packet rate, channel congestion, or signal strength. The wireless device may dynamically select one of the supported chain configuration modes in which to operate based on the series of values for the metric. In some cases, the wireless device may compute a value for the metric based on the series of values and compare the value of the metric to a predetermined threshold. In such cases, selection of the chain configuration mode may be based on the results of the comparison. In some examples, one or metrics may be used.

Abstract: Methods, systems, and apparatuses are described for adaptive dwell time for scan procedures. A wireless station (STA) may identify a scan period during which a passive scan procedure is performed on a first channel. The STA may analyze a channel congestion metric during at least a portion of the scan period. The STA may transition from the passive scan procedure to an active scan procedure on the first channel during the scan period based at least in part on the analyzed channel congestion metric.

Abstract: Methods, systems, and devices are described for merging two or more power save enabled independent basic service set (IBSS) networks. In one example, a method includes receiving, at a station of a first IBSS network, a first beacon from a second IBSS network, wherein the first beacon identifies a timing synchronization function (TSF) of the second IBSS network. The method may further include transmitting, by the station, a second beacon at a next target beacon transmission time (TBTT) of the first IBSS network based on a comparison of the TSF of the second IBSS network with a TSF stored by the station, wherein the second beacon identifies a TSF of the second IBSS network.

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, systems, and devices are described for wireless communication. In one method, a first node of an independent basic service set (IBSS) may receive a beacon from a second node of the IBSS. The beacon may include a token. Based at least in part on the token, the first node may determine that the second node has disconnected from and rejoined the IBSS. In another method, a token may be generated at a node. The token may indicate that the node has disconnected from and rejoined an IBSS. A beacon including the token may be transmitted to the IBSS responsive to the node rejoining the IBSS.
