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