A Perspective on Time Toward Wireless 6G

With the advent of 5G technology, notion latency got a prominent role in wireless connectivity, serving as proxy term for addressing requirements real-time communication. As systems evolve toward 6G, ambition to immerse digital into physical reality will increase. Besides making more stringent, this immersion bring notions time, simultaneity, presence, and causality new level complexity. A growing body research points out that latency is insufficient parameterize all requirements. Notably, one such requirement received significant attention information freshness, defined through Age Information (AoI) its derivatives. In general, metrics derived from conventional black-box approach communication network design are not representative distributed paradigms, sensing, learning, or consensus. The objective article investigate general timing networks, relation effective generation, processing, transmission, reconstruction at senders receivers. We establish statistical framework xmlns:xlink="http://www.w3.org/1999/xlink">timing systems, which subsumes both AoI. made by associating component with two basic operations: decision estimation. first use present sample existing works deal Next, it shown how can be used different models increasing complexity, starting Shannon one-way model arriving consensus, inference. Overall, fills an important gap literature providing systematic treatment various measures sets basis optimization next-generation systems.
