• 8x4 Unidirectional mode is not cost option, user will have it once
they upgrade to R4.0
• 8x4 Bidirectional mode is cost option, user need to have two RNX
hardware, and one 8x4 Bidirectional license.
• Three types of calibration come with R4.0
– Field Test Calibration
– Pathloss calibration
– PAB calibration

• 5G channel model is cost option. This model pack is a type of GSCM
(Ray-based Geometric Stochastic Channel Model) channel mode.
• GSCM is widely used for beamforming kind of testing, due to it has
angle information, which traditional TDL doesn’t have.
• Follows 3GPP 38.901 for RAN1
– Ray-based Geometric Stochastic Channel Model (GSCM)
– Five different sets of propagation conditions
– For now, we can generate to up 8x4 channels. For bigger topology it will be
updated in further release.

5G 3D Channel Modeling (<6GHz link level)
• Propagation Models from 3GPP TR
38.901
– Ray-based Geometric Stochastic
Channel Model (GSCM)
– Five different sets of propagation
conditions
• CDL models A-E
– Standard RMS delay spreads (RAN1)
• 10, 30, 100, 300, 1000 ns
• Custom also supported
• Supported Array Models
– Planar arrays: NxMxP elements
• N = number of columns
• M = number of elements per column
• Linear polarized elements (P = 1)
• Co-located cross polarized pairs (P = 2)
– 0/90 degree orientation
– +45/–45 degree orientation
– Element responses
• Ideal dipole response
• Log parabolic

• CIR channel is a playback channel model, which can be generated by
our GSCM tool or customer’s Matlab or other programming tool.
• If customer want to import their own channel they need to check file
format. Refer to D3 user guide “Appendix A: Understanding the
Format of ASC Files”
Channel Impulse Response (CIR) Playback Overview
14
Channel Impulse Response (CIR) Playback
• Support for importing ASC files
• Support for fading rates from almost
zero to 2000 Hz
• Support for time-varying excess
delays
– Glitch-free changes at physically
meaningful rates of delay change
(<500 ns per sec, or 540 km/hr)
– Supported on half the number of RNX
delay taps
• Channel samples are generated offline (ie:
MatLab) and played back in the emulator
• Allows for faster support of new channel
models
– Customer-generated files can be imported
– Offline model generation requires no new
emulator firmware for new models
• Composed of
– Complex-valued channel amplitudes
– Excess delay values
– …for all excess delays, all MIMO paths, all
time samples
