Patent ID: 11523433

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 of a UE is provided. The method includes transmitting, to a base station, a random access preamble for initiating a random access procedure; receiving, from the base station, a random access response; transmitting, to a base station, a first message for requesting system information (SI); receiving, from the base station, physical downlink control channel (PDCCH) associated with a temporary cell radio network temporary identifier (TEMPORARY C-RNTI); identifying whether a contention resolution is successful; identifying whether a random access procedure is initiated for requesting the SI; and indicating a reception of an acknowledgement for requesting the SI to upper layer in response to identifying that the contention resolution is successful and the random access procedure is initiated for requesting the SI.
