摘要： Disclosed herein are a method and apparatus for transmitting/receiving random access signals. A first random access channel (RACH) resource for a first RACH preamble format and a second RACH resource for a second RACH preamble format are configured, separately. The first RACH resource and the second RACH resource are for a UE at which Tx/Rx beam correspondence holds and for a UE at which Tx/Rx beam correspondence does not hold, respectively. A UE can use the first or second RACH resource, depending on whether or not Tx/Rx beam correspondence holds at the UE.

摘要： A method of transmitting a synchronization signal block, which is transmitted by a base station in a wireless communication system, is disclosed in the present invention. The method includes the steps of mapping a synchronization signal block including a PSS (primary synchronization signal), an SSS (secondary synchronization signal), and a PBCH (physical broadcasting channel) to a plurality of symbols, and transmitting the synchronization signal block mapped to a plurality of the symbols to a user equipment. In this case, in a symbol mapped the PSS, in a symbol mapped the SSS, and in a symbol mapped the PBCH, centers of subcarriers to which the PSS, the SSS, and the PBCH are mapped are the same and the number of subcarriers to which the PBCH is mapped is greater than the number of subcarriers to which the PSS and the SSS are mapped.
