Zusammenfassung:Disclosed is a base station which transmits an identifier of a transmission beam on a physical level for efficient beam training in a mobile communication system. The base station device shifts a phase of an orthogonal frequency-division multiplexing (OFDM) symbol in accordance to the identifier of the transmission beam, and transmits the beam. The OFDM symbol has the phase shifted to minimize an influence of the auto-correlation interference generated by the intra-cell, inter-cell, or multi-path channel delay. 이동통신 시스템에서 효율적인 빔 트레이닝을 위하여 물리계층에서 전송 빔의 식별자를 전송하는 기지국 장치가 개시된다. 기지국 장치는 전송 빔의 식별자에 따라 OFDM 심볼을 위상 시프트하며 전송하며, OFDM 심볼은 셀내 또는 셀간에서 전송 지연 또는 다중 경로 채널 지연에 의하여 발생하는 자기 상관 간섭의 영향을 최소화할 수 있도록 위상 시프트된다.
