    Abstract: A method for identifying radio signal transmission characteristics in a wireless communication system and an apparatus therefor are provided. The method may include identifying a signal transmission site, identifying a signal reception site, finding an area where a tree is present between the signal transmission site and the signal reception site, checking characteristics of the crown of the tree and characteristics of the trunk of the tree, and examining transmission characteristics of a radio signal sent from the signal transmission site to the signal reception site on the basis of the characteristics of the crown and the trunk. The method and apparatus relate 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), and may be applied to intelligent services based on the 5G communication and the IoT-related technologies.

    Abstract: The present invention relates to a communication technique for converging IoT technology with a 5G communication system for supporting a higher data transmission rate beyond a 4G system, and a system therefor. The present disclosure may be applied to an intelligent service (for example, a smart home, a smart building, a smart city, a smart car or connected car, health care, digital education, retail business, a security and safety-related service, etc.) on the basis of 5G communication technology and IoT-related technology. The present invention provides a device for testing an antenna module, the device comprising: a seating unit which has seated thereon a first antenna module comprising a plurality of antenna elements; a second antenna module which comprises a plurality of antenna elements and is disposed so as to face the seating unit so as to be capable of emitting a radio wave toward the first antenna module; and a control unit which is electrically connected to the second antenna module and tests the performance of the first antenna module by controlling the second antenna module by grouping each antenna element of the second antenna module into at least one antenna element group.
