  Terahertz (THz) communication (0.1-10 THz) is regarded as a promising
technology, which provides rich available bandwidth and high data rate of
terahertz bit per second (Tbps). However, THz signals suffer from high path
loss, which profoundly decreases the transmission distance. To improve THz
coverage, we consider the aid of mobile computing. Specifically, job offloading
decision in mobile computing and frequency allocation in communication are
co-designed to maximize distance and concurrently support ultra-reliable
low-latency communications (URLLC) services for the sixth-generation (6G)
mobile communication. Further, the above optimization problem is non-convex,
then an effective and low-complexity method is proposed via exploiting the
special structure of this problem. Finally, numerical results verify the
effectiveness of our work.
