The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The disclosure provides a method and a system for 5G New Radio (NR) based gNodeBs (gNBs) under multiple Connected User Equipment (UE) scenarios in a fast-fading environment in order to get better channel estimates at the UE side for throughput improvement by reducing packet decoding failure.
