    Abstract: A method and an apparatus for performing a random access procedure in a wireless communication system are disclosed. A method of performing a random access procedure according to an embodiment of the present disclosure may include receiving, from a base station, configuration information for providing information needed for the terminal to access the wireless communication system via a non-terrestrial network (NTN) including a satellite, wherein the configuration information includes first information for adjusting an orbit of the satellite and second information on common timing advance (TA); and determining a terminal-specific TA value for the terminal based on a location of the terminal and the configuration information; and transmitting, to the base station, a first message for the random access procedure at a timing determined based on the terminal-specific TA value and a common TA value derived from the second information.

    Abstract: The present disclosure provides a method for transmitting and receiving channel state information (CSI) in a wireless communication system and a device supporting the same.
    Particularly, a method for reporting channel state information (CSI) performed by a user equipment (UE) supported by multiple base stations in a wireless communication system may include receiving CSI related configuration information for the multiple base stations; receiving a reference signal from the multiple base stations; generating CSI based on a CSI omission rule; and transmitting the CSI to at least one base station among the multiple base stations, wherein the CSI may include information for multiple channels configured, and wherein the CSI omission rule may be determined based on at least one of i) a type of the CSI, ii) a part of the CSI, iii) priority information among CSI parameters and/or iv) priority information among the multiple base stations.

    Abstract: The present specification provides a method for receiving gap symbol information, the method being performed by a node in a wireless communication system. The method is characterized by including: receiving the gap symbol information, wherein the gap symbol information indicates the number of gap symbols pertaining to switching between a mobile terminal (MT) operation and a distributed unit (DU) operation; and performing an integrated access and backhaul (IAB) operation on the basis of the gap symbol information, wherein the node does not perform the IAB operation on the symbol indicated by the gap symbol information.

    Abstract: A method by which a terminal transmits feedback information comprises the steps of: determining, in predetermined resource units for receiving the broadcast information in a broadcast resource region, whether broadcast information collides; selecting a first shared resource in a shared resource region corresponding to a first broadcast resource in which the conflict occurs in the broadcast resource region, on the basis of a pre-defined mapping rule of the broadcast resource region and the shared resource region; and transmitting, in the selected first shared resource, feedback information including information on the occurrence of the collision, wherein the broadcast resource region is a resource region, which is defined so as to transmit or receive the broadcast information, and the shared resource region can be determined as a resource region shared between a plurality of terminals. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.
