최근 점점 더 많은 STA(모바일 스테이션)에 서비스를 제공하기 위해 WLAN(무선 근거리 통신망) 액세스 포인트(AP)가 점점 더 많이 배치되고 있습니다. 제한된 주파수 스펙트럼으로 인해 점점 더 많은 AP 및 STA 노드가 동일한 채널에 액세스하려고 합니다. 공간 스펙트럼 재사용은 DSC(동적 민감도 제어)를 통해 IEEE 802.11ax 작업 그룹에 의해 촉진됩니다. DSC는 예상 전송 노드(PTN)에서 수신된 신호 전력이 조정된 반송파 감지 임계값(CST)보다 낮을 때 공동 채널 작동을 허용합니다. 이전에 제안된 DSC 접근법은 일반적으로 운영 중에 고정된 마진 매개변수를 사용하여 노드 그룹화 없이 CST를 계산합니다. 여백 설정은 이전에 휴리스틱 방식으로 수행되었습니다. 적절한 값을 찾는 것은 열린 문제로 남아 있습니다. 따라서 본 논문에서는 PTN에서 CST의 적응적 계산을 위해 채널 인식 및 마진 없는 공식을 사용하는 노드 그룹화 방법을 사용하는 DSC 접근 방식을 제안한다. 밀도가 높은 주거용 WLAN 시나리오에 대한 수치 시뮬레이션은 총 처리량과 Jain의 공정성 지수가 각각 8.4%와 7.6% 증가한 것으로 나타났습니다(현재까지 배포된 WLAN에서와 같이).

Abstract: Lately, an increasing number of wireless local area network (WLAN) access points (APs) are deployed to serve an ever increasing number of mobile stations (STAs). Due to the limited frequency spectrum, more and more AP and STA nodes try to access the same channel. Spatial spectrum reuse is promoted by the IEEE 802.11ax task group through dynamic sensitivity control (DSC), which permits cochannel operation when the received signal power at the prospective transmitting node (PTN) is lower than an adjusted carrier sensing threshold (CST). Previously-proposed DSC approaches typically calculate the CST without node grouping by using a margin parameter that remains fixed during operation. Setting the margin has previously been done heuristically. Finding a suitable value has remained an open problem. Therefore, herein, we propose a DSC approach that employs a node grouping method for adaptive calculation of the CST at the PTN with a channel-aware and margin-free formula. Numerical simulations for dense residential WLAN scenario reveal total throughput and Jain's fairness index gains of 8.4% and 7.6%, respectively, vs. no DSC (as in WLANs deployed to present).
