Title:
METHOD AND DEVICE FOR TRANSMITTING AND RECEIVING SIGNAL IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/197329
Kind Code:
A1
Abstract:
A method and device for transmitting and receiving a signal in a wireless communication system according to an embodiment of the present invention includes: transmitting a physical random access channel (PRACH); and receiving a random access response (RAR) on the basis of the PRACH, wherein the PRACH is composed of N_MAX sequences mapped on the frequency domain, the N_MAX sequences are formed of M groups each including N sequences, the N_MAX sequences have the same length, the N_MAX sequences are generated on the basis of the same base sequence, the N sequences respectively have different cyclic shift (CS) values applied thereto; and the pattern of the different CS values may be the same for the M groups.
