More Information
Summary:A base station generates an activation FA set on a terminal based on the channel quality indication (CQI) information of a serving beam and an output beam received from the terminal, determines the transmission priority of the each FA in the activation FA set by using hybrid automatic repeat request (HARQ) feedback information on the each FA on the activation FA set received from the terminal, schedules data according to the transmission priority of the each FA in the activation FA set, and transmits the data to the terminal. So, an increase in uplink transmission can be prevented. 기지국은 단말로부터 수신되는 서빙 빔 및 이웃 빔의 CQI(Channel Quality Indication) 정보를 토대로 상기 단말에 대한 활성화 FA 집합을 생성하고, 단말로부터 수신되는 활성화 FA 집합 내 각 FA에 대한 HARQ(Hybrid Automatic Repeat reQuest) 피드백 정보를 이용하여 상기 활성화 FA 집합 내 각 FA의 전송 우선 순위를 결정하며, 활성화 FA 집합 내 각 FA의 전송 우선 순위에 따라서 데이터를 스케줄링하여 단말로 전송한다.
