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.
