Title
(EN) RANDOM ACCESS METHOD, USER EQUIPMENT AND BASE STATION
Abstract
(EN)

The present disclosure relates 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). 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. The present disclosure provides a random access method, including: acquiring configuration information, transmitting a first message including a preamble and an uplink shared channel according to the configuration information, and receiving a second message including contention resolution information from a base station.
