LTE, an acronym for Long Term Evolution, commonly known as 4G LTE, is a standard for wireless communication of high-speed data for mobile phones and data terminals. It is based on the GSM/EDGE and UMTS/HSPA network technologies, increasing the capacity and speed using a different radio interface together with core network improvements.
- NetSim LTE implementation is per 3GPP TS 36.xxx standards covering
- Devices – User Equipment (UE), E-UTRAN Node B (eNB), Mobility Management Entity (MME)
- Protocol Stack covering NAS (Non access stratum), PDCP (Packet data convergence protocol), RRC (Radio resource control), RLC (Radio link control), Concatenation
- LTE MAC
- Mapping between logical channels and transport channels
- Multiplexing of MAC SDUs from one or different logical channels onto transport blocks (TB)
- De multiplexing of MAC SDUs from one or different logical channels from transport blocks (TB)
- Priority handling between UEs by means of dynamic scheduling
- Priority handling between logical channels of one UE
- Logical Channel prioritization
- LTE PHY – OFDM-MIMO Downlink and SC-FDMA uplink, CQI – SNR
The complete white paper explaining the implementation of LTE in NetSim and detailed comparison against NS-3 test suite is available at http://www.tetcos.com/LTE_Vertification_v8.pdf
LTE is available with NetSim v8 which is expected to be shipped from mid august ’14.
