Abstract: A user equipment receives a first multiple access (MA) time resource information indicating static MA time resources in which uplink (UL) grant-free UL transmission is permitted among time resources corresponding to a fixed time length Twindow. If UL data (hereafter referred to as first UL data) to be transmitted in one (hereafter referred to as a first static MA time resource) of the static MA time resources exists, the UE transmits the first UL data in the first static MA time resource by means of a predetermined frequency resource. The UE can monitor downlink control information (hereafter referred to as first DCI) in non-static MA time resources, which are not the static MA time resources, among the time resources, and, if the first DCI is received, can transmit UL data (hereafter referred to as second UL data) to the first DCI or receive DL data.

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.
