Abstract

The method reduces transmission delay by using a selective-repeat automatic repeat request, ARQ, error detection scheme in a packet-switched data communication system. The invention provides a method for a subscriber unit to transmit acknowledgment information using a contention-free channel access scheme in addition to providing for a base site control unit to interrupt a packet currently being transmitted in order to retransmit segments of the packet when the segments have errors.
