Abstract: The disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond a 4th generation (4G) communication system such as long term evolution (LTE). A method performed by a terminal in a communication system is provided. The method includes receiving, from a base station, a common timing advance (TA) controlled by the base station, estimating a terminal-specific TA used for compensating for link delay between the base station and the terminal, and determining a TA of the terminal based on the common TA and the terminal-specific TA.

Abstract: The present disclosure relates to a communication technique for converging IoT technology with a 5G communication system for supporting higher data transmission rates after 4G systems, and a system for same. The present disclosure may be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail businesses, security and safety-related services, and the like) based on 5G communication technology and IoT-related technology. The present invention discloses a method and device for efficiently transmitting control information for multiple pieces of data transmitted to a terminal in order to efficiently support cooperative communication. Specifically, a method for a terminal in a wireless communication system to receive downlink data includes steps for: detecting first downlink control information (DCI) scrambled by a cell-radio network temporary identifier (C-RNTI); detecting second DCI scrambled by an RNTI for cooperative communication, when the first DCI has been detected; determining, when the second DCI has been detected, whether the second DCI is valid; and receiving, according to the first DCI and the second DCI, two or more pieces of downlink data when the second DCI has been determined to be valid.
