The enhanced Mobile BroadBand (eMBB) service type is expected to be the main target for the first 5G deployments internationally. The first 5G standards release has also focused on the system and technology requirements and specifications for the eMBB type of service, which is to support a great variety of modern market-related applications. In the detailed scope of the 5G-DRIVE research project promoting cooperation between the EU and China, the eMBB trials are one of the two general sets of trials to be undertaken towards promoting 5G growth. In this paper, we first identify a variety of challenges rising from the 5G evolution and then we describe the specific innovative framework of the 5G-DRIVE research, together with a detailed context for establishing appropriate KPIs, for the assessment of trials. Then we discuss the two selected use cases dealing with cloud-assisted augmented reality and indoor positioning. For each use case we provide a detailed descriptive framework accompanied by the specific KPIs that are also further extended so that to cover a broader potential scope for reliable market adaptability. We summarize our approach by discussing the performed progress together with widely defined KPIs for the joint assessment of trials in Europe and China.
