A method and apparatus for controlling a retransmission/abort timer in a telecommunications system. A pointer, V(P), that points to the upper bound of retransmitted data frames in a receiver buffer is introduced. A list includes at least one entry indicating a missed data frame for which a retransmission request has been transmitted. The entry is associated with a retransmission/abort timer that is started upon transmission of the retransmission request for the data frame. Once a retransmission timer is started, any received data frame type, whether valid or not, is counted in the incrementation of the retransmission/abort timer for an unreceived data frame. However, if the received data frame is not a valid data frame, any expiration action on the retransmission/abort timer is disabled. Also, anytime any valid frame is received, an expiration action may be taken on the retransmission timer of unreceived data frames having a sequence number less than V(P).
