The present invention relates to a link control automatic repeat request
(ARQ) operation in a wireless communication environment. When a terminal
sends an original request for communication resources, the request
includes not only payload size, but preferably quality of service
parameters associated with the data to be transmitted. During uplink
communications, the base station performs the link control based ARQ for
lost or corrupt packets. When lost or corrupt packets are identified, a
link control entity at the base station determines the appropriate
retransmission parameters and contacts the uplink scheduler, if
necessary, to obtain the corresponding communication resources for
retransmission. The additional communication resources for retransmission
are provided in a message, such as a negative acknowledgement message,
which is sent to the mobile terminal to trigger retransmission of the
lost or corrupted data.
