Abstract
In order to meet the ever-increasing demand for the throughput of 5G mobile communications, more and more frequency bands are defined for the LTE system. However, some parts of the bands have been used by satellite services. When an LTE system in one country is within the footprint of a satellite service owned by another country, to prevent the interference from the satellite services, the LTE system will avoid using the overlapped frequency bands. In order to make use of the overlapped LTE bands, a Downlink Only Frame Structure (DOFS) approach is proposed in this paper. It treats the interfered band as a secondary carrier of a licensed primary carrier and employs a standard frame structure to transmit only downlink traffic on the band. The feasibility of the proposed DOFS approach is evaluated by both considering practical implementation parameters and using a popular commercial simulation tool at an interfered spot. The results reveal that, for most part of the evaluated zone, the SINR is good enough for 64QAM modulation.
