The mmWave module for ns-3 can be used to simulate 5G cellular networks at mmWave frequencies. This module builds on top of the LTE one, and currently includes features such as:
Support of a wide range of channel models, including the model based on 3GPP TR 38.901 for frequencies between 0.5 and 100 GHz. Ray tracing and measured traces can also be used.
Custom PHY and MAC classes supporting the 3GPP NR frame structure and numerologies. They support dynamic TDD, and are parameterized and highly customizable in order to be flexible enough for testing different designs.
Custom schedulers for the dynamic TDD format
Carrier Aggregation at the MAC layer
Enhancements to the RLC layer with re-segmentation of packets for retransmissions
Dual Connectivity with LTE base stations, with fast secondary cell handover and channel tracking
Simulation of core network elements (with also the MME as a real node)
The following papers describe in detail the features implemented in the mmWave module:
End-to-End Simulation of 5G mmWave Networks is a comprehensive tutorial with a detailed description of the whole module. We advise the researchers interested in this module to start reading from this paper;
Integration of Carrier Aggregation and Dual Connectivity for the ns-3 mmWave Module describes the Carrier Aggregation implementation;
Implementation of A Spatial Channel Model for ns-3 describes the integration of the spatial channel model based on the 3GPP specifications TR 38.901 V15.0.0;
Performance Comparison of Dual Connectivity and Hard Handover for LTE-5G Tight Integration describes the Dual Connectivity feature.
These other papers describe features that were implemented in older releases:
ns-3 Implementation of the 3GPP MIMO Channel Model for Frequency Spectrum above 6 GHz describes the implementation of the 3GPP channel model based on TR 38.900;
Multi-Sector and Multi-Panel Performance in 5G mmWave Cellular Networks describes the multi-sector addition to the 3GPP channel model;
