Abstract: Embodiments herein provide a method and a UE for handling of integrity check failures of Packet Data Convergence Protocol (PDCP) Protocol Data Units (PDUs) in a wireless communication system. The method includes performing an integrity check at a PDCP layer on at least one Radio Bearer based on a Message Authentication Code-Integrity (MAC-I) of the PDCP PDU. The method includes determining a success of integrity check of the PDCP PDU or a failure of integrity check of the PDCP PDU received on the radio bearer. Further, the method includes discarding the PDCP PDU for which integrity is check failed. Furthermore, the method includes indicating a Radio Resource Control (RRC) layer about the integrity check failure on the at least one radio bearer in response to determining a trigger condition.

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. Accordingly, the embodiments herein provides a method and system method for handling a random access procedure in a Non-Terrestrial communication system (300). The method includes obtaining, by a UE (100), a default TA, a RACH resource, and a RACH configuration list. Further, the method includes selecting, by the UE (100), the default TA and the RACH resource. Further, the method includes applying, by the UE (100), the selected default TA to the random access procedure. Further, the method includes performing, by the UE (100), the random access procedure based on the selected RACH resource and the selected default TA. The proposed method can be used to reduce the CP and GT in the RACH preambles, so as to optimize the random access procedure using the default TA.
