Abstract: Provided are a method for a user equipment (UE) to request system information in a wireless communication system and a device supporting the same. The method may include: transmitting a random access preamble for requesting system information to a base station (BS); receiving, from the BS, a random access response including only a random access preamble identifier (RAPID) corresponding to the transmitted random access preamble; and considering that a random access procedure is completed.

Abstract: Provided is a method for performing a random access procedure by a terminal in a wireless communication system. The method comprises the steps of: selecting a first beam having a quality equal to or higher than a preconfigured threshold value; transmitting a random access preamble to a base station via the first beam; adjusting the threshold value when it is determined that the random access procedure has failed; and reselecting a second beam having a quality equal to or higher than the adjusted threshold value.

Abstract: A method and apparatus for acquiring system information (SI) in a wireless communication system is provided. When a user equipment (UE) moves to a (neighbor) cell and if the UE have stored system information with same system information area code (SAC), the UE reuses the stored system information (SI) and skip acquiring whole system information blocks (SIBs). If the UE does not have matched SAC, the UE checks existence of any delta SI scheduling configuration which means that a group of SI message is to be update based on the stored information. If a SI message supporting delta configuration is broadcast at a cell and if the SI message includes a parameter which UE has previously stored, the UE replaces the stored parameter by the parameter received from the SI message.

Abstract: A method and apparatus for performing sidelink transmission in an exceptional case in a wireless communication system is provided. A user equipment (UE) receives information on normal resource pools and exceptional resource pools on multiple carriers. The UE selects at least one normal resource pool among the normal resource pools on the multiple carriers, and performs the sidelink transmission by using the at least one normal resource pool. Upon detecting occurrence of the exceptional case, i.e. radio link failure (RLF), a handover, transition from an idle state to a connected state or change of dedicated sidelink resource pools within a cell, the UE selects at least one exceptional resource pool, which is mapped to the at least one normal resource pool, among the exceptional resource pools on the multiple carriers, and performs the sidelink transmission by using the at least one exceptional resource pool.
