China Government Plan for 5G
In February 2013, three ministries (MIIT, NDRC and MOST) jointly
established the “IMT-2020 (5G) Promotion group”
Objectives:
• The platform to promote the research and development of 5G
• The platform to facilitate global cooperation on 5G R&D
• Launched “national 863 project” and allocated $26M (12 month window)

5G Collaboration between CMCC and Keysight (June 2014)
Keysight in 5G
In June of this year, Keysight and CMCC publicly announced that we were engaged with an MOU on 5G research. CMCC is
developing a technology they refer to as “Smart Tile”, and each
tile is not much bigger than the size of the iPhone 5.
This Smart tile today operates at 6GHz, with 20MHz BW, and
LTE PHY. CMCC is looking to create an array of these tiles, in
many shapes, such as the Chinese character “中” as shown
here.
Picture if you will in the future, a 5G array being built into the
signage of a building, rather than yet another giant cell phone
tower in the skyline. These Smart Tiles can then be built up into
larger arrays, of 32, 64, or say 128 channels such as in the
illustration on the right.
Keysight is currently providing test solutions for ALL phases of
CMCC’s development cycle – from simulation to testing of these
Smart Tiles and arrays

Simplify Signal Creation- Custom 5G
• Flexible solution supports early 5G
wireless research and development
• Create emerging 5G candidate
waveforms, such as filter bank
multicarrier (FBMC):
- Configure custom FBMC
waveforms and set parameters
- Set FBMC filter settings such
as filter overlap factor (K) and
filter bank structure
- Use Interactive filter editor to
configure FBMC filter
coefficients
