스마트폰의 대중화와 더불어 모바일 데이터 트래픽은 폭발적인 증가 추세에 있다. 이와 같은 트래픽 요구에 부합하도록 시스템 측면에서 주파수 사용 효율을 높이는 다양한 많은 기술들이 제안되고 있다. 또 한편에서는 사용자들 측면에서 사용자의 채널 환경에 변함 없이 일정한 체감 품질을 유지하는 기술에 대한 제안도 되고 있다. 본고에서는 최근 주목받고 있는 셀 간 간섭으로 저하되는 무선 이동통신의 품질을 다중 셀 간의 협력을 통해 해결하는 MCP (multi-cell processing)에 대한 전반적인 연구동향 등을 소개한다. MCP를 위한 방법들에 대한 고찰과 이론적 모델 및 이를 위한 기술적 과제 등에 대한 논의도 소개한다.
