Course description
LTE is the natural upgrade path for carriers with GSM/UMTS or CDMA2000 networks. The different LTE frequencies and bands used in different countries imply that multi-band phones will be able to use LTE in all countries where it is supported. The course “LTE Radio Interface” analyzes the E-UTRA (LTE) in detail.One of the most important parts of the LTE is the E-UTRAN protocol Architecture which is carefully described. Furthermore the Layer 1 information Processing is analyzed.The new modulation schemes and methods are discussed by studying OFDM and MIMO in E-UTRA. How the Synchronization & Network Access is handled is discussed as well as the Downlink and Uplink Transmission Procedures.LTE Advanced features are included as well, such as Carrier Aggregation, Self Optimized Networks (SON), Coordinated Multi Point (COMP) Heterogenous Network, enhanced Inter Cell Interference Coordination eICIC and Enhanced MIMO Support.
Target audience
Target audience is radio engineers and project managers as well as network architects.
