First Claim
Patent Images
1. A method of transmitting a physical random access channel (PRACH) signal by a UE in a wireless communication system, the method comprising:
- receiving (i) first information regarding a configuration for the PRACH signal, and (ii) second information regarding a subcarrier spacing for the PRACH signal, wherein the first information is related to (i) slots for the PRACH signal, and (ii) a starting Orthogonal Frequency Division Multiplexing (OFDM) symbol index for the PRACH signal, wherein the starting OFDM symbol index is an index of a first OFDM symbol for a PRACH resource in each of the slots for the PRACH signal, and wherein the slots for the PRACH signal are slots available for transmitting the PRACH signal; and
transmitting the PRACH signal in a slot among the slots based on the first information and the second information,wherein a length of the slot for the PRACH signal is determined based on the second information, andwherein the starting OFDM symbol index is same in each of the slots.

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.
