Abstract

The present disclosure is for beam measurement in multiple beamforming. This method comprises the steps of: receiving a synchronization signal block (SSB) and obtaining an SSB index; obtaining a master information block (MIB) from the SSB; receiving a downlink control indicator (DCI) and system information block (SIB)1 on the basis of the MIB; obtaining information related to an additional signal for beam measurement from the MIB, the DCI or the SIB1; attempting detection of the additional signal; and transmitting a random access channel (RACH), wherein the RACH indicates whether the additional signal is detected and / or the SSB index.
