5세대(XNUMXG) NR(New Radio) 표준은 매우 안정적이고 지연 시간이 짧은 통신(URLLC)을 사용하여 사물 인터넷(IoT) 애플리케이션에 실시간 무선 대화형 기능을 제공합니다. URLLC 서비스의 엄격한 대기 시간 및 안정성 요구 사항을 충족하기 위해 무부여(GF) 전송이 가능합니다. K-반복 전송(K-Rep)이 소개되었습니다. 그러나 페이딩 변동은 기지국(BS)의 신호 품질에 부정적인 영향을 미칠 수 있으며, 이로 인해 반복 횟수가 증가하고 IoT 사용자 장비(UE)에 대한 간섭 및 에너지 소비에 대한 우려가 높아집니다. 이러한 어려움을 극복하기 위해 본 논문에서는 새로운 적응형 솔루션을 제안합니다. K- 신호 품질을 향상시키고 에너지 소비를 줄이기 위해 사이트 다양성 수신을 사용하는 대표 제어 방식. 성능 평가는 제안된 적응형이 K-Rep 제어 방식은 기존에 비해 통신 신뢰성을 크게 향상시키고 전송 에너지 소비를 줄입니다. K-Rep 방식을 사용하여 에너지 소비를 줄이면서 URLLC 요구 사항을 충족합니다.

Abstract: The fifth-generation (5G) new radio (NR) standard employs ultra-reliable and low-latency communication (URLLC) to provide real-time wireless interactive capability for the internet of things (IoT) applications. To satisfy the stringent latency and reliability demands of URLLC services, grant-free (GF) transmissions with the K-repetition transmission (K-Rep) have been introduced. However, fading fluctuations can negatively impact signal quality at the base station (BS), leading to an increase in the number of repetitions and raising concerns about interference and energy consumption for IoT user equipment (UE). To overcome these challenges, this paper proposes novel adaptive K-Rep control schemes that employ site diversity reception to enhance signal quality and reduce energy consumption. The performance evaluation demonstrates that the proposed adaptive K-Rep control schemes significantly improve communication reliability and reduce transmission energy consumption compared with the conventional K-Rep scheme, and then satisfy the URLLC requirements while reducing energy consumption.
