Abstract

Recently flexible mobile terminals which can freely change the shape of their device are coming out with the development of the flexible display, high capacity memory and system integration technology. The display and the antenna configuration of the future terminals will be altered according to the QoS (quality of service) and the communication environment of users. In particular, we present the new emergence of a multimedia language for human and system to communicate over subjective concepts, intention of users. The intension of users is expressed by changing the shape of their mobile terminal. In addition, antenna configuration is also related to shape of terminal and QoS of users. Therefore, we set up a specific usage scenarios for future mobile terminals and propose an adaptive MIMO (multiple-input multiple-output) schemes that can maximize channel capacity and fit to QoS of users simultaneously.

최근 유연한 디스플레이, 고용량 메모리 및 집적기술의 발전으로 가변형태의 미래형 단말기가 개발되고 있다. 이때 디스플레이의 크기 및 안테나 성상의 변화는 사용자의 QoS 및 통신환경의 변화와 관계가 깊다. 특히 사용자의 의도는 단말기의 모양변화 및 안테나 개수의 증감으로 표현되는데 기지국이 지능적으로 의도를 파악하여 적응적으로 다중안테나 기법을 변경하여 적용함으로써 단말기 사용자의 QoS를 효과적으로 만족시킬 수 있다. 그러므로 본 논문에서는 미래형 단말기의 활용시나리오를 분석하여 거기에 맞는 적응적인 MIMO기법을 사용함으로써 채널용량을 최대화 시키는 동시에 사용자의 QoS를 만족시킬 수 있는 의도 인식 통신시스템을 제안한다.
