Abstract: Various embodiments include methods, systems, and devices for communicating with a first network and a second network using a mobile device having a single radio comprising a transmitter and a receiver. The transmitter and the receiver may be tuned to the first network. The transmitter may also transmit to the first network. The receiver may tune away to the second network for a tune-away period. The transmitter may transmit to the first network during the tune-away period. A determination may be made whether the transmitter and the receiver will cause interference during the tune-away period. Transmissions may be paused from the transmitter in response to determining that the transmitter and the receiver will cause interference during the tune-away period.

Abstract: Various embodiments include methods, systems, and devices for tuning away a mobile device's receiver without retuning the mobile device's transmitter, thereby allowing the mobile device to monitor multiple networks with a single radio frequency (RF) chain while avoiding the problems often associated with tune-away methods, such as loss of throughput, loss of tracking or synchronization, delays in acknowledgments, delays in rate control or channel quality control feedback, etc. The transmitter may remain tuned to a first network while the receiver may be separately tuned to one or more other networks. In various embodiments, the separately tuned receiver may monitor for paging signals on one or more networks while the transmitter remains tuned to the first network and transmits data or control signals.

Abstract: Aspects of the present disclosure describe various techniques for handling data stall in wireless local area networks (WLANs). These techniques include, for example, a method in which wireless communications are switched at a wireless station from a first network device associated with a first radio access technology (RAT) (e.g., WLAN technology) to a second network device associated with a second RAT (e.g., wireless wide area network (WWAN) technology). The wireless station may then monitor network devices associated with the first RAT, including the first network device. The wireless station may filter results from the monitoring based at least in part on one or more threshold value and identify, based on the filtered results, one of the network devices as suitable for the wireless communications. The wireless communications may then be switched at the wireless station from the second network device to the one network device identified as suitable for the wireless communications.
