    Abstract: A terminal in a wireless communication system is provided. The terminal includes a transceiver, and at least one processor configured to receive, from BS, a RRC reconfiguration message including a reconfiguration with synchronization, transmit, to the BS, a first message including a PRACH, a PUSCH, and a C-RNTI MAC CE based on the reconfiguration with synchronization, control the transceiver to receive, from the BS, a first PDCCH and a PDSCH, wherein, for the case when the BS receives the PRACH and does not receive the PUSCH, the first PDCCH is a PDCCH addressed to RA-RNTI and the PDSCH includes a fallback RAR, and for the case when the BS receives the PUSCH, the first PDCCH is a PDCCH addressed to a C-RNTI corresponding to the C-RNTI MAC CE and the PDSCH includes an absolute timing advance command MAC CE, determine that a RAR reception is successful based on the at least one of the fallback RAR or the PDSCH, when a DRX is configured for the terminal via a RRC signalling, determine that active time for the DRX includes a time while a second PDCCH indicating new transmission addressed to a C-RNTI corresponding to the C-RNTI MAC CE has not been received after determining that the RAR reception is successful, and monitor the second PDCCH during the active time.

    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. According to an embodiment of the present disclosure, a method of a terminal in a wireless communication system includes: receiving system information including a first parameter set for a random access of a type 1 terminal, a second parameter set for a random access of a type 2 terminal, and an indicator indicating whether the type 2 terminal is supported; in case that the terminal is the type 2 terminal, identifying whether a cell on which the system information is transmitted is available to access based on the indicator; and in case that the cell is identified to be available to access, transmitting a random access preamble based on the second parameter set, wherein a bandwidth supported by the type 2 terminal is less than a first threshold value and a data rate supported by the type 2 terminal is less than a second threshold value.
