Abstract: Systems and methods for reducing collisions of transmission data for a first subscriber (e.g., a voice subscriber) with transmission data for a second subscriber (e.g., a data subscriber) at a dual sim dual active (DSDA) user equipment (UE) are described herein. A DSDA UE may be configured to implement a modified skipUplinkTxDynamic feature that avoids collisions by buffering transmission data of the data subscriber and sending a (later) scheduling request (SR) for a grant for that data. A DSDA UE may regulate data subscriber transmissions to avoid a transmission duration for the voice subscriber. A DSDA UE may reduce certain transmissions for a voice subscriber (subject to a block error rate (BLER) threshold for the voice subscriber) to lower the probability of collision. A DSDA UE may operate a data subscriber and a voice subscriber in the same cell to avoid collisions due to RF tuning and/or relative slot overlap.
