Semantic communications (SC)
SC has attracted a lot of attention
in our community recently, with the attitude towards it ranging from
snubbing it as an "old" topic of no value (e.g., semantic
communication is nothing but application-aware networking that we
solved in the 2000s) to repurposing known concepts (e.g.,
compression or simple image feature extraction) as semantics all the
way to describing semantic communication as the solution to all of
the universe's problems for the next 25 years.
To address and reconcile this broad spectrum of perspectives, we
have just written perhaps the most comprehensive paper on semantic
communications that rigorously lays the technical foundations of the
topic, by concretely explaining, with technical depth rather than
qualitative discussions, how to build from an end-to-end perspective
the next-generation semantic communication systems based on concepts
from reasoning, information theory, transfer learning, minimum
description length theory, and AI. This paper clearly answers
several fundamental questions, including:
- What does semantic communication
really mean (and what is NOT semantic communication)? What are the
challenges? (See Sections I and II)
- How do we leap from today's data-driven networks, towards
knowledge-driven semantic networks? (See Sections III and IV)
- What are the technical pillars of semantic communications? What
are the advantages? (See Sections I and II)
- What does reasoning (a term that has been used and abused in the
wireless literature so far) technically mean, what is its role for
semantic communications, and what are the concrete AI tools that we
can use to perform reasoning in semantic networks. (See Section V)
- How do we revisit key performance indicators, and more broadly,
tools like information theory, to create semantic-based KPIs ? (See
Section VI)
- How do we scale from semantic communication (link-level) to
semantic networks, including integration with emerging platforms
like ORAN? (See Section VII)
We are hoping that this paper will stir up the discussions, and also
provide concrete technical foundations that allow semantic
communications to truly become a revolutionary paradigm (for 6G and
beyond), and not just another hyped up topic that will disappear in
a few months (or be reduced to some form of compression or snubbed
as “application-aware” networking) (Walid Saad).
