摘要：
A device (110) receives consecutive negative acknowledgments (NACKs) (540), measures a downlink channel quality (530) associated with the device (110), and triggers autonomous retransmission (430) when power is limited in the device (110), when the device (110) is using a minimum usable enhanced dedicated channel (E-DCH) transport format combination (ETFC), and when one of a number of consecutive NACKs (540) is greater than a predefined number, or the measured downlink channel quality (530) is less than a predefined threshold.
