A packet data transmission protocol that uses transmission windows includes a packet control unit (PCU) (4, 8) that transmits (100) blocks of data packets from a first transmission window. A user equipment (UE) (2) sends (102) a negative acknowledgement to the PCU if the packets are not received properly, whereupon the PCU construct (106) a dummy radio link control (RLC) block (60), including at least header information upon event of an established (104) trigger (60) event. The PCU sends (108) the dummy RLC block at a more robust coding rate to prevent a RLC stall condition.
