Document Type and Number:

WIPO Patent Application WO/2019/240530

Kind Code:

A1

Abstract:

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. In accordance with an aspect of the present disclosure, a method of a terminal in a wireless communication system and an apparatus thereof are provided. The method includes identifying at least one of a master information block (MIB) or a system information block (SIB) transmitted from a first base station, identifying a second cell controlled by a second base station for transmitting a random access preamble on a random access channel, and transmitting the random access preamble on the random access channel to the second base station, wherein at least one of the MIB or the SIB includes configuration information on an initial access to the second base station, and wherein configuration information on the initial access to the second base station includes uplink configuration information for the second cell and random access channel configuration information for the second cell.
