摘要： The disclosure relates to a communication technique for merging internet of things (IoT) technology with a 5th generation (5G) communication system for supporting a data transmission rate higher than that of a 4th generation (4G) system, and a system therefor. The disclosure is applied to intelligent service based on 5G communication technology and IoT-related technology. A method for enhancing physical uplink control channel (PUCCH) reception performance, and a device therefor are provided. The method includes receiving, from a terminal, a signal for determining environment information of the terminal, identifying the environment information of the terminal based on the signal, identifying resource allocation information for a physical uplink control channel (PUCCH) format 1 signal based on the environment information of the terminal, transmitting the resource allocation information to the terminal, and receiving the PUCCH format 1 signal from the terminal based on the resource allocation information.
