Motivations Original OLPC formula for SIMO: Issue for Product Implementation: SIR_DL is more difficult to be measured than SINR_DL Question: could we replace SIR_DL by SINR_DL?
Formula Analysis Here, is DL total Tx power, is thermal noise power of whole band
Study of 4 IMT-Adv Scenarios (1) InHUMi UMa RMa
Study of 4 IMT-Adv Scenarios (2) From the ratio CDF, we can get: –There is not difference between CINR/SIR for UMi, UMa, RMa scenarios –InH need to be farther evaluated because of big difference between CINR/SIR ratio. In addition, 16m (PCLA DG) scenario is also selected for performance evaluation.
Performance Evaluation: IMT-Adv InH SIMO 1x4
Performance Evaluation: IMT-Adv InH CSM 1x4
Performance Evaluation: IEEE 16m PCLA DG 500m Scenario (1x2 SIMO)
Conclusion SINR_DL can replace the SIR_DL in 16m OLPC formula and will not bring the significant performance difference. Recommendation: accept the related modification in contribution C80216m/xxxx;
