| 3GPP LTE |
| |
| LTE, Long Term Evolution, is the trade name of the development work in 3GPP to satisfy the future vision of UMTS- higher bitrates, band-width efficiency and flexibility, as well as cost efficiency SAE, System Architecture Evolution, is the denotation for the evolution of the core network to ensure co existence of HSPA, HSPA evolution and LTE. The course covers the UMTS-LTE/SAE architecture with main focus on LTE (evolved UTRAN, E-UTRAN). The downlink and uplink frame structure of E-UTRA is studied in detail. The physical layer, covering OFDM and DFT-spread OFDM (SC-FDMA), layer 2 including MAC with scheduling, resource management and HARQ, RLC with ARQ and PDCP handling ciphering as well as layer 3 RRC and NAS are also studied. The interoperability with other 3G UTRAN is covered, as well as the comparison with future 4G technologies. |
| |
| Those working in the UMTS-LTE area requiring an understanding of the architecture and functions of the protocols. |
| |
| Basic experience of UMTS/UTRAN is an advantage but not compulsory. |
