6 5G Priori<es & Drivers From IoT to U- HDTV, ubiquity; "Ver<cals" requirements Tac<le Internet True ubiquitous "ABC" access Traffic growth: spectrum and complexity Cost /energy ITU PDNR "IMT VISION"

7 Wireless Communica<ons in 2020s become pervasive [Internet of Everything (credit: Cisco)] Pervasive Communica:on Systems consist of a very large number of things/ devices - ouen of small size and/or embedded in the environment- with compu3ng/communica3on capabili3es, which are able to: interact with each other and with users, dynamically form telecommunica3on networks, probe the environment in order to adapt and op3mize the user QoS/QoE, and process and transmit/receive large volumes of data, ouen under ultra reliable/low- latency requirements.

24 5G Enabling Radio Technology Combining scheduled and random access Scheduled access is op<mized for cellular Wireless sensor networks use random access based on conten<on (CSMA) New hybrid approaches (e.g. Funneling MAC) can offer the possibility to balance the trade- off between random and scheduled access in regions of dense traffic (closer to a sink node) where conten<on- based access becomes inefficient
