Topic 1：Aerial Non-Terrestrial Networks – Architecture, Technologies, and 5G-NR Integration (Speaker: Prof. Pin-Han Ho / University of Waterloo, Canada)

Topic 2：Optimizing Grant-Free Access for mMTC (Speaker: Limei Peng / Kyungpook National University, South Korea)

Prof. Pin-Han Ho's talk presented  a newly proposed multiple access architecture for the direct-to-cell massive Internet of things (IoT), which incorporates a suite of advanced mechanisms such as contention resolution diversity slotted aloha (CRDSA), k-repetition, grant-free access (GFA), and  delayed decoding. Prof. Limei Peng's talk explored the challenges and solutions associated with grant-free non-orthogonal multiple access (GF-NOMA) for massive Machine Type Communication Devices (MTCDs) in 5G and beyond systems.
