Patent ID: 10904921

Abstract:
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) is provided. The communication method and system include 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 includes transmitting a random access preamble on a physical random access channel (PRACH) transmission occasion from a base station, identifying a random access radio network temporary identifier (RA-RNTI) for receiving random access response (RAR) information based on a time related parameter, a frequency related parameter and an uplink carrier related parameter, and receiving scheduling assignment information scheduling a physical downlink shared channel (PDSCH) on a physical downlink control channel (PDCCH) based on the identified RA-RNTI from the base station.
