Title:
METHOD AND APPARATUS FOR RANDOM ACCESS IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/263053
Kind Code:
A1
Abstract:
The present disclosure relates to a communication technique for combining an IoT technology with a 5G communication system for supporting a higher data transmission rate than a 4G system, and a system therefor. The present disclosure can be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail businesses, security and safety-related services, and the like) on the basis of 5G communication technologies and IoT-related technologies. A method for a terminal in a wireless communication system, according to the present disclosure, comprises: measuring reference signal received power (RSRP) values corresponding to respective synchronization signal blocks (SSBs) on the basis of a plurality of SSBs which have been transmitted by a base station; identifying a coverage enhancement (CE) level of the terminal on the basis of the measured RSRP values and at least one RSRP threshold; and transmitting at least one random access preamble to the base station on the basis of the identified CE level.
