Joint Sensing, Communication, and AI: A
Trifecta for Resilient THz User Experiences
In this paper a novel joint sensing,
communication, and artificial intelligence (AI) framework is
proposed so as to optimize extended reality (XR) experiences over
terahertz (THz) wireless systems. The proposed framework consists of
three main components. First, a tensor decomposition framework is
proposed to extract unique sensing parameters for XR users and their
environment by exploiting then THz channel sparsity. Essentially,
THz band's quasi-opticality is exploited and the sensing parameters
are extracted from the uplink communication signal, thereby allowing
for the use of the same waveform, spectrum, and hardware for both
communication and sensing functionalities. Then, the Cramer-Rao
lower bound is derived to assess the accuracy of the estimated
sensing parameters. Second, a non-autoregressive multi-resolution
generative artificial intelligence (AI) framework integrated with an
adversarial transformer is proposed to predict missing and future
sensing information. The proposed framework offers robust and
comprehensive historical sensing information and anticipatory
forecasts of future environmental changes, which are generalizable
to fluctuations in both known and unforeseen user behaviors and
environmental conditions. Third, a multi-agent deep recurrent
hysteretic Q-neural network is developed to control the handover
policy of reconfigurable intelligent surface (RIS) subarrays,
leveraging the informative nature of sensing information to minimize
handover cost, maximize the individual quality of personal
experiences (QoPEs), and improve the robustness and resilience of
THz links. Simulation results show a high generalizability of the
proposed unsupervised generative AI framework to fluctuations in
user behavior and velocity, leading to a 61 % improvement in
instantaneous reliability compared to schemes with known channel
state information.
