    Abstract: Disclosed herein is a terminal configured to acquire a configuration for at least one PUCCH resource set associated with at least one downlink multicast channel, monitor a PDCCH in a search space for scheduling of a specific downlink multicast channel, and detect, as a result of the monitoring of the PDCCH, DCI having a CRC scrambled with a specific G-RNTI, wherein a specific PUCCH resource set associated with the specific downlink multicast channel may be mapped to a specific downlink frequency band having the search space for the monitoring of the PDCCH, wherein a PUCCH resource for transmission of HARQ-ACK for the specific downlink multicast channel among one or more PUCCH resources included in the specific PUCCH resource set may be indicated through the DCI.

    Abstract: Disclosed are a method and a device for transmitting or receiving HARQ-ACK information in a wireless communication system. A method for transmitting HARQ-ACK information according to an embodiment of the present disclosure may comprise the steps of: receiving, from a base station, first physical uplink control channel (PUCCH) configuration information related to an ACK/negative ACK (NACK)-based HARQ-ACK report for a multi-cast physical downlink shared channel (PDSCH) or second PUCCH configuration information related to an NACK-only-based HARQ-ACK report for the multi-cast PDSCH for each one or more uplink bandwidth parts (BWPs) configured for a terminal; receiving, from the base station, downlink control information (DCI) for scheduling of a first multi-cast PDSCH; receiving the first multi-cast PDSCH from the base station on the basis of the DCI; and transmitting, to the base station, first HARQ-ACK information for the first multi-cast PDSCH on a first PUCCH.

    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: The present disclosure relates to a wireless communication system. Specifically, the present disclosure relates to a method and an apparatus therefor, the method comprising the steps of: transmitting an RA preamble on one RO among a plurality of ROs, wherein a resource to which the RA preamble is transmitted includes the following elements, (a) a sub-interval index within a 10 ms interval, (b) a slot index within a sub-interval, (c) a symbol index within a slot, and (d) a frequency resource index; and after transmitting the RA preamble, monitoring DCI having an RA-identifier within a time window, the RA-identifier being masked in a CRC in the DCI, and receiving an RA response corresponding to the DCI, wherein one of (a) to (d) is included in a payload in the DCI, and the rest of (a) to (d) is included in the RA-identifier.
