Abstract: The present invention discloses a method of transmitting a Physical Random Access Channel (PRACH) by a terminal in a wireless communication system. Specifically, the method includes: receiving first information related to a Synchronization Signal Block (SSB) and second information related to PRACH resources; and transmitting the PRACH on a valid PRACH resource among the PRACH resources based on the first and second information. In this case, valid PRACH resource may be a PRACH resource allocated after symbols in which the SSB is received among the PRACH resources included in a PRACH slot related to the second information.

Abstract: A UE transmits a random access channel (RACH) preamble and a BS receives the RACH channel. The BS configures the RACH preamble to align boundaries of the RACH preamble with boundaries of OFDM symbols on which the RACH preamble is configured in the time domain. The UE generates/transmits the RACH preamble to align the boundaries of the RACH preamble with the boundaries of OFDM symbols on which the RACH preamble is configured in the time domain.

Abstract: The present invention relates to a wireless communication system, and more particularly, to a downlink signal transmission and reception method and device taking into account antenna port relationship. A method for the reception of a physical downlink shared channel (PDSCH) signal by a terminal in a wireless communication system, according to one embodiment of the present invention, can comprise: a step for determining a start symbol index for the PDSCH in a downlink subframe; and a step for receiving the PDSCH signal on the basis of the start symbol index. The PDSCH start symbol index (k) when the downlink subframe belongs to a specific subframe set is determined according to k=min(KThreshold, K), KThreshold being a prescribed threshold, K being the PDSCH start symbol index when the downlink subframe does not belong to the specific subframe set, and min(KThreshold, K) being the minimum value among KThreshold and K.
