Goal-oriented Tensor: Beyond Age of Information Towards Semantics-Empowered Goal-Oriented Communications
Aimin Li, Shaohua Wu, Sumei Sun +1
Optimizations premised on open-loop metrics such as Age of Information (AoI) indirectly enhance the system's decision-making utility. We therefore propose a novel closed-loop metri…
Goal-oriented Tensor: Beyond AoI Towards Semantics-Empowered Goal-oriented Communications
Aimin Li, Shaohua Wu, Sumei Sun
The intricate interplay of source dynamics, unreliable channels, and staleness of information has long been recognized as a significant impediment for the receiver to achieve accur…
Tight Upper Bounds on the Error Probability of Spinal Codes over Fading Channels
Xiaomeng Chen, Aimin Li, Shaohua Wu
Spinal codes, a family of rateless codes introduced in 2011, have been proved to achieve Shannon capacity over both the additive white Gaussian noise (AWGN) channel and the binary…
Deep Reinforcement Learning-Assisted Age-optimal Transmission Policy for HARQ-aided NOMA Networks
Kunpeng Liu, Aimin Li, Shaohua Wu
The recent interweaving of AI-6G technologies has sparked extensive research interest in further enhancing reliable and timely communications. \emph{Age of Information} (AoI), as a…
Towards Goal-Oriented Semantic Communications: New Metrics, Framework, and Open Challenges
Aimin Li, Shaohua Wu, Siqi Meng +3
Since Shannon's pioneering masterpiece which established the prototype of modern information theory, the goal of communications has long been promising accurate message reconstruct…
