QoS-guaranteed spectrum sharing in LTE networks

We propose a spectrum-sharing mechanism for LTE networks taking into account the needs of different network operators and individual QoS requirements. It increases the utilization of spectrum by regarding operators´ allocations of spectrum as a shared resource and sets user priorities for accessing this spectrum. In this paper, the example scenario given explains our approach in depth: it has better performance than comparable algorithms and it enables users from different network operators to be served with different service levels.
