LAA(License Assisted Access) 스몰 셀 아키텍처를 기반으로 Wi-Fi 이기종 네트워크와 공존하는 LAA는 비면허 채널을 LAA와 Wi-Fi 간에 공유하므로 LTE 모바일 사용자에게 높은 대역폭 효율성을 제공합니다. 그러나 두 시스템이 이기종 네트워크에서 동일한 비면허 채널을 사용하는 경우 LAA와 Wi-Fi는 서로 영향을 미칩니다. 이러한 네트워크에서 LAA와 Wi-Fi에 대한 비면허 대역 할당은 두 시스템의 서비스 품질(QoS)에 큰 영향을 미칠 수 있는 중요한 문제입니다. 본 논문에서는 비면허 대역에 대한 두 가지 할당, 즉 비면허 전체 할당(UFA), 비면허 시분할 할당(UTA) 및 LAA 데이터 패킷에 대한 해당 버퍼링 메커니즘을 연구하기 위한 분석 모델을 제안하고 시뮬레이션 실험을 수행합니다. 우리는 LAA 버퍼 큐에서 LAA와 Wi-Fi 패킷 데이터의 수용률 측면에서 이러한 비면허 대역 할당 방식의 성능을 평가합니다. 우리의 연구는 LAA 소형 셀의 채널 점유 단계와 버퍼 크기를 설계하기 위한 지침을 제공합니다.

Abstract: Based on the License Assisted Access (LAA) small cell architecture, the LAA coexisting with Wi-Fi heterogeneous networks provide LTE mobile users with high bandwidth efficiency as the unlicensed channels are shared among LAA and Wi-Fi. However, the LAA and Wi-Fi will affect each other when both systems are using the same unlicensed channel in the heterogeneous networks. In such a network, unlicensed band allocation for LAA and Wi-Fi is an important issue that may affect the quality of service (QoS) of both systems significantly. In this paper, we propose an analytical model and conduct simulation experiments to study two allocations for the unlicensed band: unlicensed full allocation (UFA), unlicensed time-division allocation (UTA), and the corresponding buffering mechanism for the LAA data packets. We evaluate the performance for these unlicensed band allocations schemes in terms of the acceptance rate of both LAA and Wi-Fi packet data in LAA buffer queue. Our study provides guidelines for designing channel occupation phase and the buffer size of LAA small cell.
