(†) Our simulation assumptions are specified in the annex I.
• In order for the 16m system to have a competitive edge over current
existing system (e.g., 3GPP LTE, 3GPP2 UMB) and its evolution, while
meeting the IMT-Advanced requirements, the suggested remedy in the
following slide should be adopted for the relative and absolute
throughput.
Suggested Remedy
• Relative Throughput Performance

>2x
Cell edge user throughput
>2.5x

• Absolute Throughput Performance

> 3.2
> 1.3
c.f.) The proposed absolute throughputs are approximately 1.5x (DL) and 2x (UL) over LTE performance.
Annex I: Simulation Assumptions
• Simulation assumptions are the same as 16m
evaluation methodology document (80r3, table 1,
table 2) except for SIMO transmission for UL due to
unclear description of uplink CSM scheduling
• We use NGMN test scenarios (with uncorrelated
spatial channel model option) except for operation
bandwidth for LTE simulation which is bandwidth
5MHz each and BS power of 43 dBm
• The layer-1 throughput in the current 16m evaluation
methodology is construed as the throughput
performance.
