Systems, methods, apparatuses, and computer program products for initialization and operation of intelligent reflecting surface. The method may include transmitting a synchronization signal block burst to a reflection surface device. The method may also include receiving a first measurement report of the synchronization signal block burst received at the reflection surface device. The method may further include determining a transmit beam for a subsequent synchronization signal block burst based on a highest strength of signals in the synchronization signal block burst. In addition, the method may include receiving a second measurement report of the subsequent synchronization signal block burst. Further, the method may include determining an arrival angle of the subsequent synchronization signal block burst at the reflection surface device. The method may also include establishing a connection with the reflection surface device based on the transmit beam and the arrival angle.
