Results summary.

Use Case	Real-time video streaming
RLC Mode	RLC UM
Associated Configuration Parameter	RLC transmission buffer
Optimization Tradeoff Parameter	Excessive buffer: increased losses due to increasing delay
	Insufficient buffer: increased losses due to increasing buffer overload
Recommended Values/Ranges	Bandwidth (MHz)		Buffer size (kB)
	1.4		1
	3		10
	5		20
	10		20
	15		20
	20		20
Use Case	File transfer
RLC Mode	RLC AM
Associated Configuration Parameter	t-PollRetransmit, t-StatusProhibit
Optimization Tradeoff Parameter	Small values of the two timers: decreased throughput due to excess of control packets
	High values of the two timers: decreased throughput due to the lack of control packets
Recommended Values/Ranges	Bandwidth (MHz)	t-PollRetransmit (ms)		t-StatusProhibit (ms)
	1.4	5		100–200
	3	100		100–400
	5	100–600		500
