우리는 시간 동기화 없이 다중 채널 단일 홉 Ad Hoc 네트워크의 노드 간 전체 브로드캐스트 및 유니캐스트를 고려합니다. 하드 지연 요구 사항에 동기를 부여 매우 안정적이고 지연 시간이 짧은 통신 (URLLC) 5G 무선 네트워크에서 우리는 제한된 지연 내에서 성공적인 노드 간 전송을 보장하기 위한 매체 액세스 제어(MAC) 방식을 설계하는 것을 목표로 합니다. 전송 지연에 대한 확실한 보장을 제공하기 위해 CSMA(Carrier Sense Multiple Access)와 같은 확률적 방식보다 결정론적 시퀀스 방식이 선호됩니다. 따라서 우리는 공통 시퀀스 기간 내에서 성공적인 브로드캐스트/유니캐스트를 보장하기 위해 설정된 스케줄 시퀀스를 설계하는 것을 목표로 시퀀스 방식을 주로 고려합니다. 이 기간은 전송 지연의 상한을 결정하므로 가능한 짧아야 합니다. 이전 연구에서는 TDD(Time Division Duplex) 하의 시퀀스 설계를 고려했습니다. 본 논문에서는 또 다른 일반적인 이중 모드인 FDD(Frequency Division Duplex)에 중점을 둡니다. FDD의 경우, 우리는 실현 가능한 시퀀스 집합의 주기에 대한 하한을 제시하고, 브로드캐스트 모델과 유니캐스트 모델 모두에 대해 시퀀스 주기가 하한과 동일한 순서를 달성할 수 있는 시퀀스 구성 방법을 제안합니다. 또한 FDD의 시퀀스 길이와 TDD의 시퀀스 길이를 비교합니다.

Abstract: We consider all-to-all broadcast and unicast among nodes in a multi-channel single-hop ad hoc network, with no time synchronization. Motivated by the hard delay requirement for ultra-reliable and low-latency communication (URLLC) in 5G wireless networks, we aim at designing medium access control (MAC) schemes to guarantee successful node-to-node transmission within a bounded delay. To provide a hard guarantee on the transmission delay, deterministic sequence schemes are preferred to probabilistic schemes such as carrier sense multiple access (CSMA). Therefore, we mainly consider sequence schemes, with the goal to design schedule sequence set to guarantee successful broadcast/unicast within a common sequence period. This period should be as short as possible since it determines an upper bound on the transmission delay. In previous works, we have considered sequence design under time division duplex (TDD). In this paper, we focus on another common duplex mode, frequency division duplex (FDD). For the FDD case, we present a lower bound on period of feasible sequence sets, and propose a sequence construction method by which the sequence period can achieve the same order as the lower bound, for both broadcast and unicast models. We also compare the sequence length for FDD with that for TDD.
