Abstract

Extended Reality (XR) applications introduce challenging requirements for radio mobile systems in terms of capacity and latency. At the same time, XR devices needs to minimize power consumption to extend battery lifetime and limit dissipated heat. Addressing capacity and latency requirements without excessively increasing power consumption of user devices requires the evolution of 5G power saving schemes. In this work, we propose an Adaptive DRX (ADRX) scheme and design a control policy to optimally adjust active duration of the DRX cycle in order to satisfy XR requirements and minimize energy consumption. To this end, we formulate the problem of selecting the user active time as a stochastic online optimization problem and present a control policy to optimally solve it. Numerical results confirm that the proposed solution increases the number of satisfied users and reduce power consumption compared to standard DRX mechanism. In particular, in a Dense Urban scenario where standard DRX cannot fulfill the requirements of any XR user, ADRX can serve up to 4-5 users per cell with 10% power saving gain.
