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.

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 dynamically select a chain configuration mode via channel analysis and energy efficiency analysis. A wireless device may monitor traffic on a wireless channel using a first chain configuration mode. The wireless device may determine an energy value associated with monitoring the traffic using the first ( e.g. , single) chain configuration, and further determine or infer an energy value associated with monitoring the traffic using a second ( e.g. , multi) chain configuration. The wireless device may perform a channel metric computation on the traffic ( e.g. , perform a QR decomposition of a channel matrix associated with the monitored traffic). The wireless device may then switch or select a chain configuration mode for operation based on a comparison between the determined energy values and the channel metric computation.

Abstract: Methods, systems, and devices for wireless communication are described. One method may include communicating with an access point (AP) during awake intervals in which the wireless device is in an awake mode, determining a congestion level associated with a radio frequency (RF) spectrum band, and determining, for an awake interval, an inactivity timeout (ITO) interval for the wireless device to remain in the awake mode based on an identified RF spectrum band and the determined congestion level used by the wireless device to communicate with the AP. A second method may include polling an AP during a delivery traffic indication message (DTIM) period, and modifying timing for the station to poll the AP based on identifying that a trigger condition has been satisfied based on a determination that at least one null data message has been received from the AP, or a predetermined threshold number of polls have timed out.

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 devices are described for wireless communication. A device (215) with multiple radios (R1, R2) may establish a wireless local area network (WLAN) connection (204) with a multi-radio gateway (210, i.e., a multiPHY gateway) and a wide area network (WAN) connection (202) with a base station (105-a). The multi-radio device (215) may receive a proxy capability indication from the multi-radio gateway (210) and may transmit connection information relating to the second wireless connection (202). The multi-radio device (215) may then establish a tunnel to the base station utilizing a proxy entity within the multi-radio gateway (210) and close a physical (PHY) connection of the second wireless connection (202) in order to save power. The multi-radio gateway (210) may receive messages (e.g., paging, broadcast, or multicast messages) from the base station (105-a) on behalf of the multi-radio device (215) using the proxy entity, and tunnel the messages through to the multi-radio device (215) using the WLAN wireless connection (204).

Abstract: This disclosure generally relates to systems, devices, apparatuses, and methods for providing adaptive discovery timing between wireless devices. A channel is identified for use by a wireless communication device. One or more channel conditions associated with the channel are determined. The system selects a value for a minimum wait time from multiple possible minimum time values based on the one or more channel conditions. In one example, the minimum wait time may represent the amount of time that the wireless communication device will wait before sending a probe request on the channel. In another example, the selected minimum wait time may represent the amount of time that the wireless communication device will remain on the channel after sending the probe request on the channel.

Abstract: Methods, systems, and devices for wireless communication are described. A station may be communicating with an access point during a first active communication period. The communication may be performed in a first power mode. The station may switch to a second power mode to transition to a sleep period. The station may determine, based on traffic indicator metric(s), whether to perform a speculative wakeup and switch to the first power mode at the end of the sleep period.
