Cognitive Hierarchy Based Coexistence and Resource Allocation for URLLC and eMBB

Abstract

5G networks will serve both enhanced mobile broadband (eMBB) and ultra-reliable low-latency communications (URLLC) traffics, indicating the heterogeneity of future communication systems. The coexistence of eMBB and URLLC and the resource allocation problem may be pretty challenging due to various quality of service (QoS) requirements. Inspired by 802.11e standard, we study a novel coexistence scheme for eMBB and URLLC devices with their vastly different demands considered, i.e., throughput for eMBB devices and error probability for URLLC. Furthermore, a realistic cognitive hierarchy (CH) theory is utilized to solve the distributed resource allocation problem. The applicability of our proposed scheme is evaluated by the simulation results.
