Apparatus and methods are disclosed to provide for a multi-SIM wireless user equipment configured for autonomous tune-away operations enabling simultaneous communication on multiple subscriptions using a shared RF chain while maintaining a voice call. A multi-SIM user equipment may be capable of communicating with a first subscription and a second subscription via a transceiver. The user equipment may be engaged in circuit switched communication utilizing a first channel corresponding to the first subscription associated with a first USIM; and the transceiver may be autonomously tuned away from the first channel and tuned to a second channel corresponding to the second subscription associated with a second USIM, while the circuit switched communication is ongoing, and autonomously tuned back to the first channel. Other aspects, embodiments, and features are also claimed and described. |
