Abstract

The present disclosure relates to a communication method and system for converging a 5^th-Generation (5G) communication system for supporting higher data rates beyond a 4^th-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. An embodiment relates to packet duplication control. Further, an embodiment relates to cell reselection. A communication method, a terminal, and a base station are provided. The method includes receiving system information related to cell reselection of a neighboring cell, from a base station on which the terminal is camping, in case that the terminal supports a supplementary uplink (SUL) and the system information includes first minimum requirement reception level information related to the SUL, acquiring a first cell selection reception level value based on the first minimum requirement reception level information related to the SUL and performing cell reselection to a new radio (NR) cell based on the first cell selection reception level value.
