Evolved UTRA(UMTS Terrestrial Radio Access) 다운링크에서는 다중 경로 간섭에 대한 고유한 내성과 다양한 스펙트럼 배열의 유연한 수용으로 인해 OFDM(직교 주파수 분할 다중화) 기반 무선 액세스가 채택되었습니다. 본 논문에서는 단일 안테나 전송을 사용하는 하향링크 OFDMA 무선 접속에서 주파수 및 시간 영역 채널 종속 스케줄링을 가정할 때 자원 블록(RB)이 동일한 사용자에게 동시에 할당되는 경우 최적의 AMC(Adaptive Modulation and Channel Coding) 방식을 제시합니다. 먼저 RB 공통 변조 방식과 RB 종속 변조 방식 모두에 대한 상호 정보를 사용하는 변조 및 코딩 방식(MCS) 선택 방법을 제시합니다. 시뮬레이션 결과는 RB 종속 변조에 대한 전력 적응 적용과 관계없이 RB 공통 변조 방식에 비해 RB 종속 변조 방식의 달성 가능한 처리량 향상이 약간, 즉 4~5%라는 것을 보여줍니다. . 또한, RB 종속 변조 방식에서는 필요한 제어 시그널링 비트 수가 RB 공통 변조 방식보다 많아진다. 따라서 단일 안테나 전송의 경우 동일한 코딩된 스트림의 여러 RB가 한 사용자에게 할당되는 경우 RB 공통 변조 및 채널 코딩 속도 방식이 선호된다는 결론을 내립니다.

Abstract: In the Evolved UTRA (UMTS Terrestrial Radio Access) downlink, Orthogonal Frequency Division Multiplexing (OFDM) based radio access was adopted because of its inherent immunity to multipath interference and flexible accommodation of different spectrum arrangements. This paper presents the optimum adaptive modulation and channel coding (AMC) scheme when resource blocks (RBs) is simultaneously assigned to the same user when frequency and time domain channel-dependent scheduling is assumed in the downlink OFDMA radio access with single-antenna transmission. We start by presenting selection methods for the modulation and coding scheme (MCS) employing mutual information both for RB-common and RB-dependent modulation schemes. Simulation results show that, irrespective of the application of power adaptation to RB-dependent modulation, the improvement in the achievable throughput of the RB-dependent modulation scheme compared to that for the RB-common modulation scheme is slight, i.e., 4 to 5%. In addition, the number of required control signaling bits in the RB-dependent modulation scheme becomes greater than that for the RB-common modulation scheme. Therefore, we conclude that the RB-common modulation and channel coding rate scheme is preferred, when multiple RBs of the same coded stream are assigned to one user in the case of single-antenna transmission.
