A UE may receive, via a first communication link that uses a first radio access technology (RAT), information that identifies a threshold associated with a second communication link that uses a second RAT. The UE may monitor one or more communications on the second communication link. The UE may determine whether a parameter associated with the second communication link satisfies the threshold based at least in part on monitoring the one or more communications on the second communication link. The UE may provide a message via the first communication link when the parameter associated with the second communication link satisfies the threshold.

Techniques for managing communication links of a plurality of radio access technologies (RATs)

Techniques for managing communication links of a plurality of radio access technologies (RATS)

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.

Multiple wi-fi channel maps for dense access point environments

Methods, systems, and devices are described for wireless communication. A station (STA) with a host processor and a radio processor may communicate with a first access point (AP) in a first subnet. The STA may store network information for the first subnet in memory of the STA. The STA may identify a second access point and determine, by the radio processor without communication with the host processor, whether the second access point is in the first subnet or a second subnet. The determination may be based at least in part on the network information stored in memory.

Inter-subnet and intra-subnet roaming

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.

Dynamic Wi-Fi roaming thresholds for dense access point environments

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.

Dynamic frequency selection channel scan optimizations

Aspects relate to a priority mechanism for prioritizing network identifiers, for example SSIDs. As described herein, a UE may obtain one or more network identifier sets, each of the one or more network identifier sets having one or more network identifiers for a first RAT and a priority level, determine one or more of the network identifier sets that are under control of a second RAT, and after the determining, manage connections to the first RAT based, at least in part, on the priority level of the network identifier sets.

Prioritization for WLAN access for LTE managing WLAN connectivity

Systems and methods are disclosed that may adjust the likelihood and/or frequency with which a wireless device performs scanning operations to reduce power consumption without degrading the ability of the wireless device to identify the best available access point with which to associate. In some aspects, the wireless device may adjust the likelihood and/or frequency of performing scanning operations based on a motion state of the wireless device, a change in the motion state of the wireless device, a signal strength of an associated access point, and/or the connection status of the wireless device.

Wi-Fi power saving based on coarse motion classification information

A multi-channel wireless device for participating on a plurality of networks. The wireless device switches from a first channel associated with a first network to a second channel associated with a second network if the wireless device has a channel dwell time on the first channel equal to or greater than a maximum channel allowance time interval for the first channel, wherein the maximum channel allowance time interval for the first channel is given by a channel switching time subtracted from a Beacon interval associated with the first network divided by the total number of networks that the wireless device is participating with.

Channel management in a Wi-Fi device in a multi-channel concurrent environment

Systems and methods are disclosed to dynamically assign priorities to beacons sent from different networks to allow a device to selectively receive a beacon from one of the networks when a conflict occurs. When two or more beacons from different networks arrive at times that do not allow the client device to receive all of the beacons, one beacon may be selected for reception based upon a priority determination. An initial priority may be assigned to beacons from each network. Further, the initial priorities may be adjusted so that a more desirable rate of receiving the beacons may be achieved.

Systems and methods for multi-channel concurrency

Systems and methods for improved communications using tunneled direct link setup are described herein. The systems and methods relate to discovery, link setup, channel switching, multicasting, link selection, and quality of service implemented in conjunction with tunneled direct link setup.
