Dynamic resource allocation schemes for eMBB and URLLC services in 5G wireless networks

The fifth generation (5G) of wireless networks features three core use cases, namely ultra-reliable and low latency communications (URLLC), massive machine type (mMTC), enhanced mobile broadband (eMBB). These cases co-exist in many practical scenarios compete for the same set time frequency resources, resulting a natural trade-off their performance. In this paper, network supporting both URLLC eMBB modes operation is studied. To guarantee ultra requirement URLLC, dynamic resource allocation scheme indicated by two-dimensional bitmap proposed. This approach capable to achieve finer granularity as well lower false cancellation rate compared state-of-the-art methods. A novel power control indication method also proposed dynamically provide different parameters user equipment (UE), while guaranteeing reliability minimizing impact eMBB. addition, we devise selection mechanism (DSM) accommodate diverse scenarios, which empowered with load prediction become more intelligent. Our extensive system-level simulation results eMBB-URLLC co-existence showcase that perceived throughput UEs increased 45.3%, about 13.3% are enjoying services at most 84% transmit savings
