摘　　要：5G mobile networks are envisioned to support both evolved mobile broadband(eMBB) and ultra-reliable and low latency communications (URLLC), which may coexistand interfere with each other in the same service cell in many scenarios. In this paper, wepropose a dynamic 2-dimension bitmap resource indication to cancel eMBB services witha finer uplink cancellation granularity and a lower probability of false cancellation. Meanwhile,a resource indication based power control method is introduced to dynamically indicatedifferent power control parameters to the user equipment (UE) based on differenttime-frequency resource groups and the proportion of overlapping resources, by which thereliability of URLLC transmission is guaranteed while the impact on the performance ofthe eMBB service is minimized. Furthermore, a dynamic selection mechanism is proposedto accommodate the varying cases in different scenarios. Extensive system level simulationsare conducted and the results show that about 10.54% more URLLC UE satisfy therequirements, and the perceived throughput of eMBB UE is increased by 23.26%.
