SimuLTE

LTE user plane simulation model, compatible with the INET Framework.

Features

General

• eNodeB and UE models
• Form-based configuration editor

PDCP-RRC

• Header compression/decompression
• Logical connection establishment and maintenance

RLC

• Multiplexing/Demultiplexing of MAC SDUs
• UM, (AM and TM testing) modes

MAC

• RLC PDUs buffering
• HARQ functionalities (with multi-codeword support)
• Allocation management
• AMC
• Scheduling Policies (MAX C/I, Proportional Fair, DRR)

PHY

• Heterogeneous Net (HetNets) support: Macro, micro, pico eNbs
• Channel Feedback management
• Dummy channel model
• Realistic channel model with
  • cell interference
  • path-loss
  • fast fading
  • shadowing
  • (an-isotropic antennas - work in progress)

Other

• X2 communication support
• (Relay support - work in progress)
• Distributed Antenna System - DAS (Testing)

Applications

• VoIP
• Gaming
• Trace Based traffic

Limitations

• User Plane only (Control Plane not modeled)
• FDD only (TDD not supported)
• no EPS bearer support – note: a similar concept, "connections", has been implemented, but they are neither dynamic nor statically configurable via some config file
• radio bearers not implemented, not even statically configured radio bearers (dynamically allocating bearers would need the RRC protocol, which is Control Plane so not implemented)
• handovers not implemented (no X2-based handover, that is; S1-based handover would require an S-GW model)

Using the configuration editor

SimuLTE also contains a form-based configuration editor to edit the most often used simulation parameters. To use it, right-click an Ini file, and choose 'Open With | SimuLTE Configuration Editor' from the context menu. Try it on 'simulations/demo/gui.ini'.
