Two-Time-Scale Resource Allocation for Joint VR and Tactile Applications

Multiple joint virtual reality (VR) and tactile applications, e.g. tele-operation, bring many challenges to wireless networks. Instead of considering the quality of service (QoS) of VR and tactile traffic independently, in this work, the integrated just-noticeable difference (JND) is introduced as a key metric to represent the joint Visuo-Tactile perceptual resolution. More importantly, considering their different time characteristics, a two-time-scale resource allocation scheme is proposed relying on the puncturing scheme for joint enhanced mobile broadband (eMBB) and ultra-reliable low latency communication (URLLC) traffic. Moreover, both mobile edge computing (MEC) computing offload and K-Repetition schemes are involved to ensure the delay and reliability constraints. simulations show that our algorithm outperforms the traditional heuristic algorithm, i.e. better VR QoS is provided while the communication requirements for tactile is satisfied.
