A proposed 3D extension to the 3GPP/ITU channel model for 800 MHz and 2.6 GHz bands

Abstract

Recently there have been many proposals to generate a complete channel model that covers wide range of carrier frequencies and take into consideration different aspects of channel propagation statistics. Many of these models focus on two dimensional propagation, i.e. propagation in the azimuth plane only. The assumption of 2D propagation may lead to inaccurate estimation of channel capacity and system level performance. In addition, few studies have focused on the propagation characteristics in the 800 MHz band. In this paper a complete 3D channel model is generated and examined through 3D ray tracer tool. The paper proposes detailed channel related parameters for urban macro and micro-cell environments at carrier frequencies of 800 MHz and 2.6 GHz. The paper analyzes the channel in terms of best-fit normal parameters for large scale parameters, path loss models, cross-correlation of large scale parameters, and de-correlation distance for both line-of-sight and none line-of-sight conditions. The paper uses the generated statistics to extend the current 2D 3GPP/ITU channel model to 3D model and compare the propagation statistics generated by this model with the ray tracer predictions.

Heterogeneous Cloud Radio Access Networks: Enhanced Time Allocation for Interference Mitigation

“…In this study, a 3D 3GPP/ITU channel model proposed in a previous work [28] is implemented which considers both propagation in the azimuth and elevation planes. The 3D ITU model accounts for large scale fading by considering path loss and shadowing effects and small scale fading through detailed modelling of the Multipath Components (MPCs).…”

Channel Measurements and Models for High-Speed Train Communication Systems: A Survey

“…The proposed 3D 3GPP channel model introduced the zenith AoD and zenith AoA that are modeled by inverse Laplacian functions [117]. The 3D extensions of SCM and the WINNERII/WINNER+ channel models were proposed in [118] and [119], respectively, and an extension of the IMT-A channel model to the elevation plane was proposed in [120], [121]. However, none of the aforementioned channel models has considered any of the HST scenarios.…”

System level 5G evaluation of GFDM waveforms in an LTE-A platform

“…An operating frequency of 2.6 GHz and a bandwidth of 20MHz was assumed. The 3D 3GPP-ITU channel was applied, where the effect of elevation is also considered [13]. The system level parameters are summarised in Table III To execute the system level analysis, bit level simulators for both waveforms (OFDM and GFDM) have been developed and used to calculate the PER for each user for 9 MCS modes.…”
