SimuLTE

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

Dependencies

The current master/head version requires

• OMNeT++ 5.5.1 and INET 4.2.0

Setup

• PATH variable should include omnet bin directory and inet bin directory
• LIBRARY_PATH and LD_LIBRARY_PATH must include the location of the corresponding shared object libraries

Features

General

• eNodeB and UE models
• Full LTE protocol stack

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
  • inter-cell interference
  • path-loss
  • fast fading
  • shadowing
  • (an)isotropic antennas

Other

• X2 communication support
• X2-based handover
• Device-to-device communications
• Support for vehicular mobility

Applications

• Voice-over-IP (VoIP)
• Constant Bit Rate (CBR)
• Trace-based Video-on-demand 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)
