Part Time / September  26-Mondey Morning

This workshop will delve into the radio resource and interference management (RRIM) problem in 5G cellular networks. Starting with the visions and requirements for 5G multi-tier cellular networks (in terms of data rate, latency, cost and energy),  the corresponding key enabling technologies for increasing energy bandwidth, spectral efficiency, and extreme densification and offloading are discussed, followed by a discussion on  the challenges of radio resource and interference management (e.g., power control, channel allocation, user association) raised by these enabling technology in 5G cellular networks, specially in co-channel deployment scenarios. Open research issues and possible approaches to tackle those challenges will be described.  Also, a taxonomy of the related literature addressing the different aspects of the RRIM problem will be provided highlighting the different methodologies   adopted for analysis and optimization of RRIM in 5G multi-tier cellular networks.
