- W3105968325 abstract "Time-varying channel is an important characteristic of a mobile communication system, which will cause random fluctuations of the quality of received signal at the user equipment (UE). Link adaptation is one of the key technologies to deal with the variant channel condition. It maximizes the data transmission rate over a limited bandwidth. In this paper, we design and implement an end-to-end link-adaptive system based on the 5G New Radio (NR) standard, adopting software defined radio (SDR) equipment as the baseband processing module. In the designed system, the selection of channel quality information (CQI) and the link-adaptive module are implemented at the base station (BS). The design and implementation of the physical layer according to 5G NR standard, including system parameters, synchronization scheme and duplex mode, are provided. Further, the over-the-air (OTA) results validate the feasibility of the system design, and show that link adaptation module can significantly improve the quality of the received signal." @default.
