The aim of this module is to understand and analyze the main challenges for future centralized radio access networks. The courses will focus on enhancements techniques introduced in LTE-A networks where cooperation among base stations is strengthened in order to increase Quality of Service levels and radio spectral efficiency. The course will then go through the architectural evolutions from distributed to centralized cloud-based radio access networks (C-RAN) and analyze the key features and challenges of these evolutions. At the end of this course, students should be able to conceive, model and evaluate cooperation mechanisms for C-RAN and conduct optimization studies for future cellular networks.
Lecturers: Badii Jouaber (TSP) and other faculty member of TSP.
