White paper on Beyond 5G/6G KPIs and Target Values

With substantial contributions from 6G-BRAINS to the 5G-PPP Test, Measurement and KPIs Validation Working Group, a white paper on “Beyond 5G/6G KPIs and Target Values” has been published. The main objective of this document is to present the current view of the available B5G and 6G KPIs from 5G PPP phase III projects with a focus on projects of the ICT-52 call. This view includes mapping to KPIs previously defined for 5G and evaluating how they might evolve to fit the B5G and 6G visions. We are presently at the start of the 6G research era, where visionaries and researchers are interplaying to define a vision for 6G. To ensure the direction of innovations towards realizing 6G it is critical that KPIs are defined at an early stage to help steer the process. The KPIs are either evolved from previous generation KPIs or are new and being defined in coordination with definition of new features and use cases. It is at this stage that this white paper makes its contribution, in collecting KPIs from active research projects based on work on new features and use cases. The paper consists of two main technical parts. The first part gives an overview of standard network KPIs with defined target values for 5G system. These are well known KPIs that will be evolved to 6G by changing target values. The second part presents KPIs collected from ICT-52 research projects aimed at B5G and 6G system. These KPIs are processed in terms of being grouped according to KPI type or context, and they are presented with references to standards and target values where possible and available. The white paper is intended to be updated and re-published every year to track the B5G and 6G KPIs evolutions. The evolutions will occur as projects, use cases and functionalities mature. KPI definitions from new B5G and 6G projects from projects participating in the 6G SNS R&I Work Programme will be taken into account when available (2023). Future version of this report will also integrate more information on KPIs target values and definition of methodology for how to measure them.  DOI: 10.5281/zenodo.6577506, URL: https://doi.org/10.5281/zenodo.6577506 .
