Abstract
Apparatus and methods are disclosed to provide for a multi-SIM wireless user equipment configured for block-level, or slot-level tune-away operations enabling simultaneous communication with a plurality of channels. The first and second channels may correspond to different RANs, each of which the user equipment may subscribe to as corresponding to information in a plurality of SIMs at the user equipment. In other examples, the first and second channels may correspond to different cells within a single RAN. In either case, the tune-away operations disclosed provide for reduced data loss at the first channel and in some examples improved communication performance at the second channel. Other aspects, embodiments, and features are also claimed and described.
