4. Nov 2006 Channel Model Scenario Environment Descriptions CM1 LOS
Residential
Typical home with multiple rooms and furnished with furniture, TV sets lounges, etc. The size is comparable to the small office room. The walls/floor are made of concrete or wood covered by wallpaper/carpet. There are also windows and wooden door in different rooms within the residential environment.
CM2
NLOS
CM3
Office
Typical office setup furnished with multiple chairs, desks, computers and work stations. Bookshelves, cupboards and whiteboards are also interspersed within the environment. The walls are made by metal or concrete covered by plasterboard or carpet with windows and door on at least one side of the office.
Cubical, laboratory, open and closed office can be treated as a generic office. Typically these offices are linked by long corridors.
CM4
CM5
Library
Typical small size library with multiple desks, chairs and metal bookshelves. Bookshelves are filled with books, magazines, etc. Some tables and chairs were interspersed between the bookshelves. At least one side of room has windows and/or door. The walls are made of concrete.
CM6
CM7
Conference Room
Typical conference room with metal shelves, white board and office window.
CM8
CM9
Desktop
Typical office desktop and computer clutter. Partitioning surrounded this environment
CM10
Corridor
Passage way that links different offices

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

19. Unresolved Issues – Matlab Code
Nov 2006
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
