Patent ID: 11576212

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) are provided. The communication method and system 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, terminal, and base station for performing a random access procedure in a wireless communication system are provided. The terminal method includes, receiving, from a base station, a radio resource control (RRC) reconfiguration message including dedicated configuration information for an RA, identifying whether information on a maximum number for message A (MSGA) transmissions is configured in the dedicated configuration information, and in case that the information on the maximum number is configured in the dedicated configuration information, performing the RA procedure based on the information on the maximum number.
