Learning outcomes |
The megatrends of 5G communications usage include enhanced Mobile Broadband, Ultra Reliable Low Latency Communications (URLLC) and massive Machine Type Communications (mMTC). This curricular unit addresses the comprehension, conception and optimization of 5G network architectures and communication protocols, with central focus in the URLLC and mMTC components, including communications from vehicles to everything (V2x). Students will understand how to design 5G New Radio people-centric networks that facilitate other industrial sectors, as medical sciences, transportation, education. Practical considerations will be complemented by aspects of deployment. A top-down approach is followed while exploring system operation, functional interconnections and interfaces, and considering the protocols stack and related block diagrams, for sub-6 GHz and millimetre wavebands.

Teaching Methodologies and Assessment Criteria |
The theorical contact hours (2 h/week) aim at communicate theoretical concepts associated with the syllabus of the curricular unit. The theoretical-practical contact hours (1 h/week) aim at communicating practical knowledge to the students, by solving problems, research and practical works. In the laboratory (1 h/week) students will develop laboratory assignments.
