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 disclosure provide methods and apparatuses for improving tune-away in some dual-SIM, dual standby mobile devices. For example, methods are provided for setting a first subscription of a first subscriber identity module (SIM) of a user equipment (UE) as a designated data subscription (DDS), wherein the first subscription supports only first technology type communication services, and setting a second subscription of a second SIM of the UE to support only the first technology type communication services in response to setting the first subscription as the DDS, wherein the second subscription is able to support both the first technology type communication services and second technology type communication services different than the first technology type communication services. As such, improved tune-away may be accomplished.
