LTE Functionality Training

This LTE Functionality Training course will undertake an in-depth study of the LTE air interface. It will begin with a discussion of the radio channel environment and the related RF propagation issues to help you understand the problems that OFDM/MIMO solves. This is followed by a discussion of the modulation principles along with a detailed look at the LTE physical layer structure as it complements the modulation and MIMO channels. We conclude with a discussion of the LTE idle mode functionality and physical layer procedures with an emphasis on channel quality and random access techniques. Also connected mode — with emphasis on the scheduler, power control, and Link Adaptation — is further analyzed, and user mobility cases are explicitly presented with emphasis on parameter configuration and optimization.
