The ambitious fifth generation (5G) cellular system requirements and performance targets motivated standardisation bodies to consider wide bandwidth allocations for 5G in the mm-wave band. Nevertheless, parts of the considered band are already allocated to satellite services in several regions. We tackle this challenge by proposing a co-existence framework for 5G and fixed satellite services (FSS). We focus on the uplink of both systems and consider realistic 5G deployment scenarios with multiple users and multiple radio access network (RAN) cells. We propose a generic and controllable co-existence constraint applicable to different 5G numerologies and configurations. In addition, we derive a protection distance to guarantee the co-existence constraint and utilise several 5G system features to define soft constraints. The 5G/FSS coexistence is investigated based on performance of the 5G user plane. Simulation results show that the 5G deployment scenario is a key factor in setting the protection distance. In addition, the FSS elevation has a significant effect on the identified distance. The results suggest that both systems can operate in the same band without very large protection distance at a controllable expense of a small, e.g., 1% - 5%, performance loss.
