Title: METHOD FOR TRANSMITTING AND RECEIVING RANDOM ACCESS CHANNEL, AND DEVICE FOR SAME
Abstract:
The present invention provides a method whereby user equipment transmits a random access channel (RACH) in a wireless communication system. In particular, the method comprises: receiving information on actually transmitted synchronization signal blocks (SSBs) and RACH configuration information on RACH resources; and transmitting an RACH in at least one RACH resource among RACH resources mapped to actually transmitted SSBs on the basis of the information on the actually transmitted SSBs and the RACH configuration information, wherein the actually transmitted SSBs are repeatedly mapped to RACH resources a number of times within an RACH configuration period based on the RACH configuration information, the number of times being the number of the actually transmitted SSBs multiplied by a positive integer.
