Abstract

A communication scheme and system for converging a 5^th generation (5G) communication system for supporting a data rate higher than that of a 4^th generation (4G) system with an internet of things (IoT) technology, and a method and apparatus therefor are provided. The applicable to intelligent services (e.g., smart home, smart building, smart city, smart car, connected car, health care, digital education, retail, and security and safety-related services) based on the 5G communication technology and the IoT-related technology.

Claims
