이 논문에서는 지상 네트워크와 협력하는 저궤도(LEO) 위성 액세스 네트워크가 이종 네트워크를 구성하는 STIN(위성-지상 통합 네트워크)에서 사용자 연관 및 스펙트럼 할당의 공동 문제를 조사합니다. 밀도가 높은 네트워크 시나리오에 대한 백홀 용량을 향상시킬 뿐만 아니라 원활한 적용 범위를 제공합니다. 그러나 위성의 궤도 이동으로 인해 접근 가능한 위성과 백홀 용량이 동적으로 변경됩니다. 더욱이, 스펙트럼 공유는 여러 액세스 포인트(AP)의 커버리지 중첩으로 인해 발생하는 심각한 동일 채널 간섭(CCI)에 직면할 수 있습니다. 본 논문에서는 STIN의 동적 특성, 백홀 용량 제한 및 간섭 관리의 영향을 고려하여 전체 합계 속도를 최대화하는 것을 목표로 합니다. 그런 다음 최적화 문제는 두 가지 하위 문제, 즉 지상 통신과 위성 통신에 대한 자원 할당으로 분해되며 둘 다 매칭 알고리즘을 통해 해결됩니다. 마지막으로 시뮬레이션 결과는 STIN의 총 속도와 스펙트럼 효율성 측면에서 제안된 방식의 효율성을 보여줍니다.

Abstract: This paper investigates the joint problem of user association and spectrum allocation in satellite-terrestrial integrated networks (STINs), where a low earth orbit (LEO) satellite access network cooperating with terrestrial networks constitutes a heterogeneous network, which is beneficial in terms of both providing seamless coverage as well as improving the backhaul capacity for the dense network scenario. However, the orbital movement of satellites results in the dynamic change of accessible satellites and the backhaul capacities. Moreover, spectrum sharing may be faced with severe co-channel interferences (CCIs) caused by overlapping coverage of multiple access points (APs). This paper aims to maximize the total sum rate considering the influences of the dynamic feature of STIN, backhaul capacity limitation and interference management. The optimization problem is then decomposed into two subproblems: resource allocation for terrestrial communications and satellite communications, which are both solved by matching algorithms. Finally, simulation results show the effectiveness of our proposed scheme in terms of STIN's sum rate and spectrum efficiency.
