We investigate the licensed shared access (LSA) concept based spectrum sharing ideas between public safety (PS) and commercial radio systems. While the concept of LSA has been well developed, it has not been thoroughly investigated from the public safety (PS) users’ point of view, who have special requirements and also should benefit from the concept. Herein, we discuss the alternatives for spectrum sharing between PS and commercial systems. In particular, we proceed to develop robust solutions for LSA use cases where connections to the LSA system may fail. We simulate the proposed system with different failure models. The results show that the method offers reliable LSA spectrum sharing in various conditions assuming that the system parameters are set properly. The paper gives guidelines to set these parameters.
