Abstract:
A method in which a satellite or a terrestrial earth station that is included in a satellite communication system that shares a frequency resource with a terrestrial communication system allocates a frequency resource is provided. The satellite divides an area of a first satellite beam into at least one sector. The satellite determines a first sector in which a satellite terminal is located among the at least one sector. The satellite determines a second sector corresponding to the first sector among at least one sector that is included in a first terrestrial cell. The satellite allocates at least one of first frequency resources for the second sector to the satellite terminal. The first terrestrial cell is located within an area of a second satellite beam adjacent to the first satellite beam.
Abstract:
A method of designing and communicating a beam in a communication system is provided. More particularly, a method of designing and communicating a beam in a communication system using carrier aggregation in order to increase a maximum data rate in a multiple beam mobile communication system is provided. By applying carrier aggregation, a maximum data rate can be improved.
Abstract:
A method of forming a beam and a method of allocating a resource in a long term evolution (LTE)-based mobile communication system are provided. More particularly, a method of forming an adaptive satellite multiple beam for enhancing multiple beam performance and a method of allocating a resource that can relieve interference in a beam that is formed according to the method in a multiple beam system in which satellite communication and mobile communication is coupled based on LTE are provided. When providing a communication service that supports both satellite communication and ground communication, performance degradation can be reduced with the same interface, and by providing a method of forming an adaptive beam and a method of allocating a resource by relieving interference of the formed beam in consideration of a position of the terminal by independently allocating a subcarrier to the terminal and enabling the terminal to process the subcarrier, performance of a multiple beam can be improved.
