3 3 Comparison Summary of DL Pilot Results/Sourc e LGE( C#798)Intel (C#694r1)MOT(2532r2)Samsung(C#6 72r1) Nortel(C#618)Huawei(C#679 ) Panasonic (C#716) Ericsson(C#7 62r1) 2 TX common LGE, Intel, Samsung best Similar performance. Intel’s original and Intel/ITRI/MediaTek/ Posdata best Similar performance - Huawei is the best - Others are similar - Interference case, pilot boosting gains are lower when pilot to pilot interference is present - Intel and Ericcson pattern for interference- limited case are almost the same performance - Intel, LG, Ericcson are the best for high speed, noise limited case 4Tx commonLGE best,- Intel, Samsung, Med best - Intel has additional gain for interference limited MediaTek, Intel and MOT are among the best. Intel/Samsung are the best with low pilot density - Nortel, LG best @ high speed - Nortel, Alcatel-Lucent best @ low speed - Huawei is the best - Others are similar 4Tx dedicated - LGE, Motorola, MediaTek @ low/mid SNR - Samsung and Intel @ high SNR - Intel original and Intel-ITRI-MediaTek- Posdata best for low SINR all channel - MOT, LG bets for PB3 and high SNR - Intel, MOT, MediaTek best @ SNR < low and mid SNR. - Samsung best @ high SNR - Huawei is the best - Others are similar CommentNoise limited only with testing interference limited scenarios Include noise limited, interference limited scenario. Also pilot boosting, - Noise limited - Intel, MediaTek, MOT are robust in velocity speed Noise limited only - Alcatel-Lucent, MOT have large degradation at high speed - Intel, Samsung are robust for speed - Noise limited - 1D Ch. Est which is not consistent with evaluation criteria - Noise limitedFocus on the sector- specific pilot, not different pilot pattern Pilot pattern in mulit-cell scenario should minimize collisions between cells

4 4 Which is the Best – 2Tx Intel (798, 694r1, 762r1) LG (798, 762r1) Samsung (798) Huawei (679) Ericsson(762r1)

5 5 Which is the Best – 4Tx Intel (798, 694r1, 253r2, 672r1) LG (798, 694r1, 618) MOT (798, 694r1, 253r2) MediaTek (798, 694r1, 253r2) Samsung (798, 694r1, 253r2, 672r1) Nortel (618) Alcatel-Lucent (618) Huawei (679)

6 6 Robustness for High Mobility Intel(694r1, 762r1, 253r2), LG(618, 762r1) Nortel(618) Ericcson (762r1) MediaTek (253r2) MOT (253r2)

7 7 Robustness for Interference-limited Intel (694r1, 716, 762r1) Ericsson (762r1)

8 8 Recommendation Adopt Intel’s 1, 2 stream pilot (C80216m- 08_648.doc) and 4 stream pilot designs (C80216m-08_121r1.doc) for their overall superb performance and its robustness under various scenarios based on members’ independent studies
