    Abstract: A system for converging fifth generation (5G) communication systems for supporting higher data rates beyond fourth generation (4G) systems with a technology for Internet of things (IoT) is 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 system is provided for determining system information validity by acquiring and storing a first system information block and other system information, including information on a public land mobile network (PLMN) identity and a value tag, and determining whether the stored system information is valid for the cell. As another example, a terminal and base station are provided for performing beam failure detection and a recovery procedure using first and second configuration information for beam failure recovery (BFR) and if failure is detected, initiating a first random access (RA) procedure and if second configuration information is received while the first RA procedure is ongoing, terminating the first RA procedure and initiating a second RA procedure based on the second configuration information.

    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). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology. The present disclosure provides a method and an apparatus for performing a random access by a terminal in a wireless communication system by starting a backoff timer for a random access preamble retransmission, determining whether a criterion to select a contention free random access resource is met during the backoff timer, selecting a random access resource for a transmission of a random access preamble when the criterion is met during the backoff timer, and transmitting, to a base station, the random access preamble in the selected random access resource.

    Abstract: A communication method and system for converging a fifth generation (5G) communication system for supporting higher data rates beyond a fourth 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 of a terminal for performing a random access procedure in a wireless communication system is provided. A method includes identifying whether physical random access channel (PRACH) occasions are configured for an active uplink (UL) bandwidth part (BWP) of a serving cell; based on the PRACH occasions not being configured for the active UL BWP and the serving cell being a special cell (SpCell), switching an active downlink (DL) BWP of the SpCell; and performing the random access procedure on the active DL BWP of the SpCell and the active UL BWP of the serving cell. A method by a terminal for transmitting a message 3 (Msg3) in a random access procedure is provided. In addition, a method by a terminal for system information (SI) request is provided.

    Abstract: The present disclosure relates to a communication method for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system, and a system therefor. The present disclosure can be applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail business, security and safety related service and the like) on the basis of 5G communication technology and IoT related technologies. The present disclosure relates to a method by which a terminal determines a beam in a wireless communication system, comprising the steps of: performing a beam sweeping procedure of discovering a reception beam of the terminal and a transmission beam of a transmission reception point (TRP) of the wireless communication system, the orienting directions of the reception beam and the transmission beam being aligned to each other; determining a rotation angle of the rotated terminal by using a rotation detection sensor provided to the terminal when the terminal is rotated after the beam sweeping procedure is performed; determining a reception beam on which a downlink signal is to be received on the basis of the determined rotation angle when the determined rotation angle is a predetermined angle or greater.
