Abstract:
1. A method in a wireless device comprising: configuring the device for discontinuous reception (DRX) wherein for DRX the wireless device has periods of on durations when a radio is on and periods when the radio is to be off; receiving a first transmission during an on-duration; if the first transmission was not successfully received sending a negative acknowledgement (NACK) and entering an additional on-duration wherein the additional on-duration is during a period when the radio is to be off and where the radio is on, the start of the additional on-duration based upon a hybrid automatic repeat request (HARQ) round-trip time (RTT), the additional on-duration encompassing a plurality of retransmission opportunities; monitoring for an asynchronous retransmission during the additional on-duration; and monitoring for dynamic allocations during the additional on-duration.
