Abstract: Methods and apparatuses for performing communication in a wireless communication system. A user equipment (UE) receives first satellite ephemeris information related to a first satellite and information related to a first validity duration corresponding to the first satellite from a base station; and restarts a first validity timer, based on second satellite ephemeris information related to the first satellite being received from the base station while the first validity timer having the first validity duration is running. The UE obtains a first TA for the first satellite based on the first satellite ephemeris information before the first validity timer restarts, expires, or stops after starting based on the first validity duration, and the UE obtains a second TA for the first satellite based on the second satellite ephemeris information before the first validity timer expires or stops after restarting based on a second validity duration.

Abstract: The present invention relates to a method for performing a random access procedure in a wireless communication system and a device therefor, the method comprising a step for receiving NPRACH configuration information and a step for transmitting a random access preamble on the basis of the NPRACH configuration information, wherein the NPRACH configuration information includes information indicating whether only a first preamble format is supported, only a second preamble format is supported, or both the first preamble format and the second preamble format are supported. If both the first preamble format and the second preamble format are supported according to the NPRACH configuration information, the random access preamble is transmitted using the first preamble format, and, if both the first preamble format and the second preamble format are supported according to the NPRACH configuration information, the random access preamble is transmitted using the second preamble format.

Abstract: Disclosed is a method of transmitting a physical uplink control channel (PUCCH) by a user equipment (UE) in a wireless communication system. The method includes receiving information related to an index of a PUCCH resource set for the PUCCH and to the number of resource blocks (RBs) for the PUCCH, and transmitting the PUCCH through a PUCCH resource based on a first RB offset. A second RB offset of the PUCCH resource set is obtained based on the index, and the first RB offset is obtained by multiplying the number of RBs by the second RB offset.
