Abstract:
디스플레이 장치 및 그 제어 방법이 개시된다. 본 디스플레이 장치는 패널 구동부, 복수의 스위칭 소자를 통해, 복수의 게이트 라인 및 복수의 데이터 라인과 연결된 복수의 픽셀을 포함하는 디스플레이 패널 및 복수의 게이트 라인을 통해 게이트 신호를 출력하도록 패널 구동부를 제어하고, 복수의 데이터 라인을 통해, 게이트 신호가 출력된 복수의 스위칭 소자와 연결된 복수의 픽셀에 데이터 전압을 인가하도록 패널 구동부를 제어하여 영상을 디스플레이 패널에 표시하는 프로세서를 포함하고, 프로세서는, 영상의 비율 선택을 위한 사용자 입력에 기초하여, 복수의 픽셀 중 사용자 입력에 따라 영상을 표시하기 위한 일부의 픽셀과 연결된 적어도 하나의 게이트 라인으로 게이트 신호를 출력하도록 패널 구동부를 제어할 수 있다.
Abstract:
PURPOSE: A method for determining transmission band of band combined system is provided to select one among transmission bands in communication terminals and connect to base station, thereby restraining resources to be concentrated in a specific transmission band. CONSTITUTION: A base station determines weight value information per transmission band(311). The base station transmits a preamble and broadcasting information through a broadcasting channel(313). A terminal obtains an initial alignment(315). The terminal determines primary band based on weight value information(317). The terminal requests connection to the base station through the primary band(319). The base station responds to connection request through a mapping band(323). The terminal performs communication with the base station(325).
Abstract:
PURPOSE: A method and a system for transmitting a physical downlink control channel for aggregating bandwidths in a mobile communication system are provided to obtain resource allocation information for the entire bandwidth even though a terminal decodes a only PDCCH(Physical Downlink Control CHannel) of a specific sub bandwidth. CONSTITUTION: A BS(Base Station) generates DCI(Downlink Control Information)(S430). The DCI includes resource allocation configuration information for a sub bandwidth except the sub bandwidth. The BS transmits the generated DCI to an MS(Mobile Station) through a PDCCH of a sub bandwidth. The resource allocation configuration information includes a carrier index, the first band switching flag, and a time flag.
Abstract:
PURPOSE: A method for allocating an uplink feedback channel for feeding back ACK/NACK of data packets corresponding to an enhanced physical downlink control channel and an apparatus thereof are provided to reduce the overhead of an up-link feedback channel by feed backing information of decoding data packets. CONSTITUTION: An up-link feedback channel is obtained. An up-link feedback channel includes a resource area which is mapped with each index of CCEs(Control Channel Element) included in two or more different resource allocation control channels. A base station assigns information related to the decoding success of a data packet to the resource area of the up-link feedback channel. The control information about transmitted data packet is mapped with a transmitted CCE combination. The information related to the decoding success of the data packet is fed back to the base station using the resource area of the up-link feedback channel.
