5G NR WIRELESS REPEATER OF BROADBAND CONVERGENCE SERVICE FOR 5G NEW RADIO

摘要

The present invention relates to a repeater for a mobile communication terminal using a 5G new radio (NR) service band. More particularly, according to the present invention, provided is a broadband integrated service repeater for 5G NR, which comprises: a modem Rx block obtaining a system frame number (SFN) value and downlink (DL)/uplink (UL) shape information synchronized with a 10 m/sec frame boundary signal; and an RF interface block generating a switching signal through the SFN value and the DL/UL shape information received from the modem Rx block. The modem Rx block includes a field programmable gate array (FPGA) having a digital filter capable of detecting a peak value of power after passing only a sub-band value of an SSB block, and generating the DL/UL shape information as a waveform image.
