Abstract:
There is desire for public safety networks to meet the increasing demands for sharing images or videos among first responders and incident commanders more effectively. Long term evolution (LTE) is considered to be a candidate for achieving such broadband services. However, out-of-coverage areas tend to happen at the cell edge areas or inside buildings because the cell areas of each base station for public safety networks is larger than those of commercial one. This paper proposes a relay selection scheme for the relay communication using device-to-device (D2D) communication as a means to fill coverage holes in public safety LTE (PS-LTE). The scheme, based on effective path throughput from an out-of-coverage terminal to a base station via an in-coverage relay terminal, enables the optimal relay terminal to be selected. System level simulation results reveal that the proposed scheme can increase the user ratio, satisfying the throughput requirement for video transmission. Additionally, an evaluation intended for actual parties of firefighters shows that the proposed scheme enables 99% of out-of-coverage users to achieve the requirement throughput for transmitting video images.
