Title:
METHOD AND APPARATUS FOR INITIAL ACCESS OF TERMINAL IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/212618
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. A method for a terminal may include: identifying a reference subcarrier spacing value; receiving random access channel (RACH) configuration information; determining a resource to be used for transmitting a random access preamble based on the RACH configuration information and the reference subcarrier spacing value; and transmitting the random access preamble using the determined resource.
