communication system by which selectably to cause retransmission and
re-ordering of data communicated pursuant to effectuation of the
communication service. A service request generator generates a service
request that requests initiation the communication service in which data
retransmission is effectuated at the MAC layer. And, a buffer is utilized
at the MAC layer at which data is re-ordered, if necessary, to place the
data in form for delivery to higher logical layers defined in the
communication system.
