Abstract
The exemplary embodiments of the invention utilize techniques that provide an amount of scheduling flexibility for retransmissions (e.g., downlink HARQ retransmissions) while also limiting the amount of time within which a UE can expect retransmissions. Thus, the network retains scheduling flexibility while the UE can still operate in DRX, for example. In one exemplary embodiment, a method includes: receiving an initial transmission of information; and receiving a retransmission of the information, where the retransmission is received within a window of time having a predetermined duration, where the window of time is arranged to begin at a predetermined time or after a predetermined time interval. In further exemplary embodiments, the predetermined duration of the window of time is measured using a DRX retransmission timer and/or the predetermined time or the predetermined time interval is measured using a HARQ RTT timer.
