Claim of US Patent No. 11,071,075


1. An apparatus for transmitting a synchronization signal, the apparatus comprising:a radio resource configuring unit configured to:divide a radio resource designated for synchronization into a timing synchronization frequency region and a beam synchronization frequency region, and
form a plurality of radio resource blocks in the beam synchronization frequency region, each of the plurality of radio resource blocks including two or more neighboring radio resource elements among radio resource elements included in the beam synchronization frequency region;

a timing synchronization performing unit configured to transmit, to a terminal through at least one antenna beam generated in the timing synchronization frequency region, a first synchronization signal for frequency synchronization and a second synchronization signal for frame synchronization in order to perform timing synchronization; and
a beamforming synchronization performing unit configured to transmit a beam synchronization signal, as a third synchronization signal, to the terminal through antenna beams generated for the plurality of radio resource blocks formed in the beam synchronization frequency region in order to perform beamforming synchronization,
wherein:
the number of the radio resource elements included in each of the plurality of radio resource blocks is determined by the number of antenna beams being able to be generated by the terminal receiving the beam synchronization signal.
