Abstract

Efficient utilization of Resource Blocks (RBs) whilst simultaneously meeting the desired Quality of Service (QoS) of Ultra-Reliable Low Latency Communication (URLLC) and Enhanced Mobile Broadband (EMBB) applications in the downlink Fifth Generation (5G) is an open research problem. Therefore, this paper proposes two dynamic Resource Block (RB) allocation techniques known as Channel-aware Dynamic RB Allocation (CDRA) and Urgency-aware Dynamic RB Allocation (UDRA) in our attempts to address the problem. These techniques dynamically allocate the number of RBs for packet transmission according to a user channel quality (CDRA) as well as packets urgency (UDRA) to achieve the 1 ms latency with 10-5 Packet Loss Ratio (PLR). An extensive computer simulation was conducted based on realistic radio propagation and interference affected in a cell using the new frame structure, mini-slot 0.143 ms Transmission Time Interval (TTI) of 15 kHz Subcarrier Spacing (SCS), dynamic Control Channel (CCH) and short Hybrid Automatic Repeat Request (HARQ) features. The simulation results showed the efficacy of UDRA over CDRA where UDRA has explicitly improved the multimedia QoS namely PLR, latency, and throughput in the downlink 5G network.
