PANEL DISCUSSIONS

Goal-oriented Semantic Token Communications –Evolution or Revolution for Wireless Communication System?

With the explosive emergence of new AI applications, i.e., intelligent robots, remote driving, and intelligent interactive devices, the real-time uplink transmission of multimodal content poses new challenges to wireless networks. These trends are driving the evolution of communication systems toward semantic token communication, which focuses on the “meaning” behind transmitted bits to facilitate more intelligent and adaptive communication services. Moreover, the use of generative foundation models or multimodal large models in semantic communication further leads to tokenized communication, where the basic units of meaningful transmission become tokens instead of bits. Potential new transmission schemes, evaluation metrics, QoS definitions need a fresh look of investigation.

So far, semantic token communication remains in its baby phase. How to define the semantic tokens in the context of human to human communication, human-to-machine communication, and machine-to-machine communications remain unclear. Also, there are controversial views toward this topic. For instance, is semantic token communication a technological advancement that solely pertains to the information source, or it needs to take wireless channel into consideration? Will the design of semantic token communication change the end-to-end architecture of the wireless system, or it only affects some modules of the air interface, or it is just an add-on feature that won’t change any of the fundamental modules? To tackle these intricate challenges head-on, we extend a warm invitation to leading scholars from both academia and industries to join the panel discussion and share views.

Questions

  1. What is semantic token communication? Is semantic token communication equivalent to source compression?
  2. Will semantic token communication change the traditional wireless architectureDoes semantic token communication involve changes to the air interface architecture?
  3. Semantics vs bits: what is the difference? Semantic token communication focuses on the “meaning” while conventional communication focuses on bit recovery. If the air interface still transmits and verifies/reconstructs data in bits, then for the air interface, it remains a bit-based transmission system. So, does semantic token communication require wireless communication to transmit and verify information in semantic units?
  4. What are the most relevant scenarios for semantic token communication In which scenarios will semantic token communication most likely play a crucial role? will it be XR/VR, intelligent robots, remote driving, satellite communication, or portable AI devices, such as smart glasses?
  5. What are the remaining challenges to bring semantic token communication into reality?What topic should the industry and academic society collaborate on to advance semantic token communication? Potential areas include joint encoding and air interface optimization, knowledge base design, generative paradigms, multi-agent communication, or architectural design.
