Abstract
Access terminals are adapted to facilitate optimized tune-away operations in multi-subscription wireless communication devices. According to one example, an access terminal can communicate on a first subscription. After a period of time, the access terminal can tune away from the first subscription to a second subscription to perform a communication activity corresponding to the second subscription. After tuning back to the first subscription, the access terminal may transmit uplink data while ignoring any absolute grant received after tuning back to the first subscription, and/or transmit a scheduling information message in response to tuning back to the first subscription from the second subscription. Other aspects, embodiments, and features are also included.
