IChannelModel

module interface

Provides the interface for modules implementing the model of the radio channel. Such modules are responsible for providing functions to compute the Signal to Interference-plus-Noise Ratio (SINR) of received frames, taking into account channel effects such as propagation loss, fading/shadowing, and inter-cell interference.

Inheritance diagram

The following diagram shows inheritance relationships for this type. Unresolved types are missing from the diagram.

Implemented by

Name	Type	Description
ChannelModelBase	simple module	This is the base module for developing more realistic models of the radio channel. It primarily provides the initialization of parameters such as the reference to the Component Carrier (CC) and its associated parameters related to the channel model itself.
D2dChannelModel	simple module	D2D-capable channel model: StochasticChannelModel plus the device-to-device channel math (RSRP/SINR, D2D interference, D2D reception decision). It is the channel model of the D2D NICs on all propagation studies; the pathLossType parameter (inherited from StochasticChannelModel) selects TR 36.814, 36.873 or 38.901.
IdealChannelModel	simple module	A channel model that replaces propagation modelling with a configurable packet error rate. Path loss, shadowing and fading are not modelled at all: the attenuation is zero and the reported SINR/RSRP are a fixed large value, so the CQI reported to the scheduler is pinned at its maximum and the transport block size never varies with the channel.
StochasticChannelModel	simple module	The full PHY link model: everything between a transmitted air frame and the decision on whether it was received. The channel impairments are modeled statistically -- drawn from the distributions of a 3GPP propagation study, rather than computed from the geometry of an actual environment -- which is what sets this model apart from IdealChannelModel, where there are no impairments at all, only a configured packet error rate.
Tr36873ChannelModel	simple module	StochasticChannelModel preset with the propagation formulas of 3GPP TR 36.873, "Study on 3D channel model for LTE", v12.7.0, December 2017. It differs from its base type only in the pathLossType default; there is no C++ class of its own behind the name. Note that the study supplies the path loss, LOS probability, shadowing and angular attenuation only; the rest of the link model is the same for every propagation study.
Tr38901ChannelModel	simple module	StochasticChannelModel preset with the propagation formulas of 3GPP TR 38.901, "Study on channel model for frequencies from 0.5 to 100 GHz", v16.1.0, December 2019. It differs from its base type only in the pathLossType default; there is no C++ class of its own behind the name. Note that the study supplies the path loss, LOS probability, shadowing and angular attenuation only; the rest of the link model is the same for every propagation study.

Used in compound modules

Name	Type	Description
LteNicBase	compound module	The LteNicBase module serves as the foundational building block for LTE networking in Simu5G. It integrates protocols for LTE communication, including PDCP, RLC, MAC, and PHY layers. This base module allows higher-level modules, such as User Equipment (UE) and eNodeB (evolved Node B), to configure and utilize these layers according to their specific requirements.
NrNicUe	compound module	Defines a User Equipment (UE) network interface card that supports both LTE and NR (New Radio) technologies. It extends the LteNicUe module by adding additional submodules and parameters to support NR-specific functionalities. D2D support is added by the NrNicUeD2D subtype.
