3GPP Channel Model Types for 4G and 5G
Understanding 3GPP Channel Models in LTE and NR Introduction 3GPP defines various channel models for LTE and NR to simulate real-world propagation conditions and evaluate system performance. These models are specified in: TS 36.101 – LTE User Equipment Radio Transmission and Reception TS 38.141 – NR Base Station Conformance Testing TS 38.901 – Channel Model for 5G The common channel models include: AWGN (Additive White Gaussian Noise) EPA (Extended Pedestrian A) EVA (Extended Vehicular A) ETU (Extended Typical Urban) MBSFN (Multimedia Broadcast Single Frequency Network) TDL Models (TDL-A, TDL-B, TDL-C, TDL-D, TDL-E) These models help evaluate device performance under different multipath fading and mobility scenarios. They can be configured to mimic diverse propagation scenarios allowing testing under different propagation conditions, simulating real-world scenarios. For LTE channel models, they are defined in TS 36.101. They include models like EPA, EVA, ETU and MBSFN ar...
