1. A device comprising:
a memory to store a plurality of instructions; and a processing unit configured to execute instructions in the memory to:
determine whether power is limited in the device,determine whether the device is using a minimum usable enhanced dedicated channel, E-DCH, transport format combination, ETFC,receive consecutive negative acknowledgments, NACKs,determine whether the number of consecutive NACKs is greater than a predefined number,measure a downlink channel quality,determine whether the measured downlink channel quality is less than a predefined threshold,trigger autonomous retransmission, where a number of retransmissions are sent consecutively without waiting for receipt of a negative acknowledgement before starting the next retransmission, when power is limited in the device, when the device is using the minimum usable ETFC, and when one of:
the number of consecutive NACKs is greater than the predefined number, andthe measured downlink channel quality is less than the predefined threshold, determine whether a difference between an estimated data signal-to-interference ratio, SIR, associated with a channel and a SIR for a transport format is greater than a certain decibel level, and
trigger autonomous retransmission when power is limited in the device, when the device is using the minimum usable ETFC, and when the difference is greater than the certain decibel level. |
