    Abstract: A downlink transmission timing determination method performed by an integrated access and backhaul (IAB) node comprises: receiving a synchronization offset from a parent node; receiving a parameter related to a timing advance (TA) between an uplink transmission timing and a downlink reception timing; and on the basis of the synchronization offset and the parameter, determining a downlink transmission timing, wherein in comparison with the downlink reception timing, the downlink transmission timing has a time difference corresponding to a value calculated on the basis of the synchronization offset and the parameter.

    Abstract: The present disclosure relates to a method for transmitting and receiving a signal in a wireless communication system and a device supporting same. The method comprises the steps of: obtaining message A comprising a physical random access channel (PRACH) preamble and a physical uplink shared channel (PUSCH); and transmitting the message A. The PUSCH is transmitted in one or more PUSCH occasions among continuous PUSCH occasions within a frequency domain and a time domain. The PRACH preamble is obtained from one or more predetermined PRACH preambles. The indices of the one or more PRACH preamble are mapped to the one or more PUSCH occasions in the ascending order.

    Abstract: Proposed is a method for transmitting a physical random access channel (PRACH) preamble in a wireless communication system. Specifically, a method performed by user equipment (UE) comprises the steps of: receiving, from a base station, setting information including a first power ramping step for a two-step random access channel (RACH) and a second power ramping step for a four-step RACH; transmitting, to the base station, information including a first preamble and a physical uplink shared channel (PUSCH) for a two-step RACH on the basis of the first power ramping step; and transmitting, to the base station, a second preamble for a four-step RACH by using the second power ramping step, on the basis of the number of retransmissions of the information exceeding a maximum number of retransmissions associated with a preset two-step RACH.

    Abstract: The present invention discloses a method for a user equipment to receive system information in a wireless communication system. Particularly, the method is characterized in detecting a first synchronization signal block configured with a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS) and a Physical Broadcasting Channel (PBCH) at a specific frequency position, determining a presence or non-presence of system information corresponding to the first synchronization signal block within a first synchronization raster corresponding to a specific frequency position based on a system information indicator included in the PBCH, and if the system information corresponding to the first synchronization signal block is determined as not existing, determining a second synchronization raster having system information exist therein based on the system information indicator.

    Abstract: The present disclosure provides a method for transmitting a random access channel (RACH) by a UE in a wireless communication system. Particularly, the method includes receiving information about actually transmitted synchronization signal blocks (SBBs) and RACH configuration information about RACH resources and transmitting a RACH in at least one RACH resource among RACH resources mapped to actually transmitted SSBs on the basis of the information about actually transmitted SSBs and the RACH configuration information, wherein the actually transmitted SSBs are repeatedly mapped to RACH resources by a positive integer multiple of the number of the actually transmitted SSBs in a RACH configuration period based on the RACH configuration information.

    Abstract: A method of transmitting a synchronization signal block, which is transmitted by a base station in a wireless communication system, is disclosed in the present invention. The method includes the steps of mapping a synchronization signal block including a PSS (primary synchronization signal), an SSS (secondary synchronization signal), and a PBCH (physical broadcasting channel) to a plurality of symbols, and transmitting the synchronization signal block mapped to a plurality of the symbols to a user equipment. In this case, in a symbol mapped the PSS, in a symbol mapped the SSS, and in a symbol mapped the PBCH, centers of subcarriers to which the PSS, the SSS, and the PBCH are mapped are the same and the number of subcarriers to which the PBCH is mapped is greater than the number of subcarriers to which the PSS and the SSS are mapped.
