In the Tx timesharing for universal mobile telecommunications system (UMTS) and global system for mobile communications 1Tx‐2Rx dual‐SIM dual‐active (DSDA) scenario, UMTS UMTS enhanced uplink (EUL) had performance degradation due to discontinuous transmission. Therefore, the code rate‐based mitigation scheme was evaluated to reduce the performance degradation. Even though this scheme had significant gain, high complexity implementation was required. Thus, the boost power‐based mitigation scheme is proposed and analysed from the throughput improvement and implementation complexity point of view.
