Joint Preference Metric for Efficient Resource Allocation in Co-Existence of eMBB and URLLC

Abstract

The co-existence of enhanced Mobile Broadband (eMBB) and Ultra-Reliable Low Latency Communication (URLLC) services in emerging 5G technology are essential to support many diversified cutting edge applications with the requirement of high data rate and low latency. In this multiservice co-existence, optimizing resource allocation with efficient scheduling is a challenging task. The hard latency bound URLLC traffic selectively overlapped by puncturing the ongoing eMBB transmission. This results in a potential loss to the data rate of eMBB traffic. Therefore, we propose resource allocation based on a joint metric of the minimum achievable rate of eMBB and optimal URLLC placement demand for minimizing loss. The resource allocation to each URLLC users in any mini-slot is done based on the proposed metric.
