    Abstract: The present invention provides a method for transmitting a random access channel (RACH). Particularly, the method includes receiving PRACH configuration information including information about a slot (RACH slot) available for transmission of the RACH and information indicating a subcarrier spacing for a PRACH, and transmitting a RACH preamble in the RACH slot on the basis of the PRACH configuration information and the subcarrier spacing, wherein the length of the RACH slot depends on the subcarrier spacing.

    Abstract: A method of determining a position in a wireless communication system and apparatus thereof are disclosed. The present invention includes receiving system information including information on a reference cell and at least one neighbor cell from a location server, receiving positioning reference signals (PRSs) from the reference cell and the at least one neighbor cell using the system information, measuring reference signal time difference (RSTD) of each of the at least one neighbor cell for the reference cell, and transmitting the at least one measured RSTD to the location server. And, the RSTD is a relative timing difference between two cells. Moreover, the system information includes at least one cell for obtaining a system frame number (SFN) by the UE, as the reference cell or the at least one neighbor cell.
