Abstract: Disclosed is a method for a terminal to receive a synchronization signal block (SSB) in a wireless communication system. In particular, the method comprises receiving, on a first half frame or a second half frame included in a wireless frame, at least one SSB mapped to a plurality of symbols, wherein the at least one SSB is any one of a first SSB received on the first half frame and a second SSB received on the second half frame, and a signal of the same type is mapped to a first symbol included in a plurality of symbols to which the first SSB is mapped and a second symbol included in a plurality of symbols to which the second SSB is mapped, but a phase of the first symbol and a phase of the second symbol are different.

Abstract: According to the present invention, transmission power of a preamble for a random access process is determined on the basis of a preamble transmission counter and a downlink path loss estimate value in a wireless communication system. The preamble transmission counter is calculated by using the number of preamble transmissions performed by a user equipment for the random access process, regardless of a random access channel resource. The downlink path loss estimate value is calculated for a synchronization signal linked to the random access channel resource used in transmitting a corresponding preamble. Other downlink path loss estimate values can be calculated for other synchronization signals.

Abstract: The present disclosure discloses a method of receiving a downlink channel by a user equipment (UE) in a wireless communication system. Particularly, the method includes receiving a synchronization signal block (SSB) including a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH), obtaining information about the position of a downlink bandwidth from the PBCH, and receiving the downlink channel within the downlink bandwidth determined on the basis of the obtained information about the position of the downlink bandwidth. The information about the position of the downlink bandwidth is an offset from the position of a bandwidth of the SSB to the position of the downlink bandwidth.

Abstract: A user equipment receives RACH resource information comprising connection relationship information between RACH resources and synchronization blocks of a cell, and RACH preamble information representing a preamble sequence dedicated to the user equipment. On the basis of the RACH resource information and the RACH preamble information, the user equipment transmits the preamble sequence on a first RACH resource connected with a first SS block of the cell, and transmits the preamble sequence on a second RACH resource connected with a second SS block of the cell.
