摘要： Disclosed is a cooperative relay station that relays between a base station and a mobile station when retransmitting a signal. Also, disclosed is a base station that receives a signal from a mobile station in mutual cooperation with the cooperative relay station. After the cooperative relay station receives and decodes a signal that the mobile station transmits to the base station or a service relay station, if an error of the decoded signal does not exist, it stores the received signal. If an error occurs when the base station decodes the signal that the mobile station transmits, the base station requests retransmission for the signal with the error to the cooperative relay station. If the cooperative relay station gets a request of retransmission, it transmits the signal that the base station requests to the base station. In this was, since an error rate may be reduced when the base station requests retransmission of the signal, resource reuse efficiency may become improved, interference may be reduced, and it is easy to adapt to a service being sensitive to time delay.
摘要翻译：公开了在重发信号时在基站和移动台之间进行中继的协作中继站。此外，公开了一种从协作中继站相互协作地接收来自移动台的信号的基站。在协作中继站接收并解码移动台向基站或服务中继站发送的信号之后，如果解码信号的错误不存在，则存储接收到的信号。如果基站解码移动台发送的信号时发生错误，则基站向合作中继站请求具有错误的信号的重发。如果协作中继站获得重传请求，则将基站请求的信号发送给基站。这是因为，当基站请求重发信号时可能会降低错误率，所以资源重用效率可能会提高，可能会降低干扰，容易适应对时间延迟敏感的业务。

摘要： A communication resource allocation method for solving resource request imbalance content in a cell is provided. Considering a propagation environment, the base station allocates a whispering resource to a whispering area, the whispering resource being one part of the communication resource and the whispering area being a peripheral area of the first base station, and allocates a speaking resource to a speaking area, the speaking resource being other parts of the communication resource and the speaking area being a border area of a cell. When the resource request of the whispering area is increased, the base station further allocates a part of the speaking resource to the whispering area or increases a ratio of the whispering resource. When the resource request of the speaking area is increased, the base station controls a threshold value for identifying the whispering and speaking areas or increases a ratio of the speaking resource.

摘要： A digital video playback apparatus selectively reproduces video signals which are recorded by using a plurality of cameras each at different angles and method therefor. A digital playback apparatus reads out first and second video steam data and first and second audio stream data, which are compressed and recorded on a recording medium. A demultiplexer separates a signal output of the digital playback apparatus into system information, the first and second video stream data, and the audio stream data. First and second video decoders expand the first and second compressed video stream data outputs. An audio decoder decodes and expands the audio stream data outputs from the demultiplexer. A key input section generates first and second angle selection signals. A controller analyzes the system information, and generates a switching control signal and a plurality of delay time and gain control signals. A switch selects the first and second video stream data according to the switching control signal. A delay time and gain control circuit delays the audio stream data outputs from the audio decoder according to the delay time control signals, and controls gains of the delayed audio stream data according to the gain control signals.

摘要： Disclosed are a base station, a relay station, and a terminal according to a method for designing a cellular system for improving resource usage efficiency by reducing interference between relay stations and interference between the base station and the relay station. The relay station gets control signals that terminals served by the base station transmit, and registers terminals, levels of the control signals of which are bigger than a predetermined value, to a list of the interference terminals. The relay station checks an interference resource through resource allocation information of the base station, checks an available resource corresponding to a resource except the interference resource among a resource allocated by the base station, and allocates some of the available resource to the terminal.
