Abstract: A sidelink data transmission method for ultra-low latency and high reliability communication in a wireless communication system and an apparatus therefor are provided. A method for transmitting sidelink configuration information by a base station according to an embodiment of the present disclosure includes transmitting first sidelink configuration information to a transmitting UE and a receiving UE, transmitting second sidelink configuration information to the transmitting UE and the receiving UE, receiving a result of repeated transmission of sidelink data from the transmitting UE or the receiving UE, determining at least one of whether the sidelink data is retransmitted or the number of repeated transmissions for next sidelink data to be transmitted, and transmitting downlink control information to the transmitting UE and the receiving UE.

Abstract: Provided are a repetitive transmission method for ultra-low latency and highly-reliable communication in a wireless communication system, and an apparatus therefor. A method for transmitting data by a terminal according to an embodiment of the present invention comprises the steps of: receiving information on the repetition number of transmission for a physical uplink shared channel (PUSCH) from a base station; receiving, from the base station, information on frequency hopping applied to the the PUSCH repetition configuring the the PUSCH repetition; determining a frequency resource for the PUSCH repetition based on the information on the frequency hopping; and performing the the PUSCH repetition.

Abstract: The present disclosure relates to an apparatus and method for transmitting RAN (Radio Access Network) slice-related information, and discloses a user equipment including: a transceiver configured to receive individual control information provided individually for each RAN slice from a network node, and to perform a random access procedure using resources individually configured for each RAN slice based on the individual control information; and a processor for controlling reception of the individual control information, and the random access procedure. Such a user equipment provides an effect of being able to separately transmit control information including, for example, system information for each slice for RAN slicing.

Abstract: The present specification relates to an apparatus and method for performing random access. This specification discloses a method for performing random access by a terminal in a non-terrestrial network system, the method comprising the steps of: performing a search for a cell of a non-terrestrial network on the basis of a synchronization signal block transmitted from a non-terrestrial network node; after the search for the cell is completed, receiving, from the non-terrestrial network node, random access-related information about the cell of the non-terrestrial network; generating a random access preamble on the basis of a frequency resource area of a random access channel related to the cell of the non-terrestrial network; and transmitting the generated random access preamble to the non-terrestrial network node. Performance degradation can be reduced when random access is performed in a non-terrestrial network system.
