  17. Summary of channel Models • Residential – LOS (CM1) and NLOS (CM2)* • Office – LOS (CM3) and NLOS (CM4) • Library – LOS (CM5) and NLOS (CM6)* • Conference Room – LOS (CM7) and NLOS (CM8) • Desktop – LOS (CM9) and NLOS (CM10)* * Derived from LOS Su-Khiong Yong, Samsung-SAIT

  18. Resolved Issues in TG3c Channel Modeling Sub-committee Final Report(06/195r4) • Dealing with circular polarized model. • Change environment conference room LOS (CM7) and NLOS (CM8) to office (LOS ONLY, CM7) and residential (LOS ONLY, CM8) • Effects of antenna de-convolution in 398r3? Is the channel model antenna specific? • Matlab Code is not yet available. How long we can wait? • Shall not consider circular polarized model • Effects of antenna de-convolve for all other channels except circular polarized • All RX antennas were de-convolved but NOT the TX • n in the LOS office (CM3 and CM4) does not match to the PL n • n used in CM3 and CM4 was derived based on small set of data to reflect  value for small scale usage. • Stay as it is • Fix h, height of the antenna and d, distance of the antenna? • Not fixed but uniformly distributed as described in CM9 Su-Khiong Yong, Samsung-SAIT

  19. Unresolved Issues – Matlab Code • CM1, CM3 and CM9 have multiple representations. How to deal? • Stay as it is. • Matlab Code is not yet completely finalized due to • New contribution in 478r0 for CM4 • Rick will provide an update on the code • Validation of the simulated channel by measurement results. • How to deal with the improvement of the amplitude statistics, 06/4530? • Channel becomes “semi-statistical” • To be considered in the selection criteria document 05/493r22 • How to integrate Matlab Packages discussed 0459r1 and 0468r0 and what is the timeline? • Target to complete within one month time frame after the Dallas Meeting • Distribution of the Matlab Package. • Distribute in terms mat file, Excel sheet and/or Matlab functions? • Yes Su-Khiong Yong, Samsung-SAIT

  20. Motion • Motion by Ali Sadri, we shall consider circular polarized channel model for LOS office environment (CM7) for Channel Modeling purposes. Seconded by S. K. Yong • Yes - 5 • No - 15 • Abstain -7 • Motion failed. Su-Khiong Yong, Samsung-SAIT

  21. Motion • Motion by Ali Sadri, we shall consider circular polarized channel model for LOS Residential environment (CM8) for Channel Modeling purposes. Seconded by S. K. Yong • Yes - 5 • No - 14 • Abstain – 6 • Motion failed Su-Khiong Yong, Samsung-SAIT

  22. Future Plan • Fine Tune Matlab code: Some last minutes changes to parameterization and new contributions on NLOS data. Su-Khiong Yong, Samsung-SAIT

  23. Motion • Motion to approve the Channel Modeling Document 06/195r5. • Moved by S. K. Yong • Seconded by S. Kato • Yes - 20 • No - 0 • Abstain -4 • Motion carried. Su-Khiong Yong, Samsung-SAIT
