A method and an apparatus for quick retransmission of signals in a
communication system are disclosed. A transmitting terminal, e.g., a base
station, transmits signals in a form of packets to a receiving terminal,
e.g., a subscriber station. The receiving terminal determines if the
packet was intended for the receiving terminal, and if so, the receiving
terminal demodulates the packet. The receiving terminal then computes a
quality metric of the packet, and compares the computed quality metric
with a quality metric contained in the packet. If the quality metrics
match, the packet is declared correctly received, and is forwarded for
further processing. If the quality metrics fail to match, the receiving
terminal sends a request for retransmission of the packet. The
transmitting terminal determines which packet needs to be retransmitted
based on the request for retransmission. The transmitting terminal then
schedules the packet for retransmission.
