Abstract(in English) | The fifth-generation (5G) new radio (NR) standard employs ultra-reliable and low-latency communication (URLLC) capabilities to provide real-time wireless interactive systems 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) were 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 the proposed adaptive K-Rep control schemes satisfy the URLLC requirements while reducing energy consumption and achieve significant improvement in reliability and reduction of transmission energy consumption compared with the conventional K-Rep scheme. |
