FIELD: information technology. ^ SUBSTANCE: method involves sending to a receiving device from a transmitting device a radio link control (RLC) retransmission scheme selected from a plurality of RLC retransmission schemes, and using the selected and sent scheme at least at one of the receiving device and the transmitting device. In another exemplary non-limiting version, the method involves detecting, at the receiver, a gap in RLC protocol data unit (PDU) sequence numbers, associating a timer with the gap, and starting the timer when the gap is detected. In yet another exemplary non-limiting version, the method involves detecting a gap in a RLC PDU sequence, monitoring a hybrid automatic repeat request (HARQ) channel for a period of time to determine if a predetermined bit has changed, and determining if a transmission is lost. ^ EFFECT: determining when to retransmit protocol data units. ^ 29 cl, 14 dwg |
