摘要： The present invention relates a method and apparatus for transmitting/receiving data using multiple codewords in a communication system using SC-FDMA (single carrier frequency division multiple access). A transmitter generates the multiple codewords for user data and transmits the generated multiple codewords. A receiver receives the multiple codewords and sequentially performs decoding and SIC (successive interference cancellation) on the received multiple codewords. Therefore, this structure can minimize a PAPR (peak to average power ratio) and considerably reduces interference between symbols in a frequency selective fading environment.

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： 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.

摘要： A resource division, allocation, and transmitting/receiving method of downlink for reducing inter-cell interference in an orthogonal frequency division multiplexing system are provided. Entire downlink radio resources are divided into a traffic resource group for a traffic channel and a control resource group for a control channel, the traffic resource group is divided into a first traffic resource group for the intra-cell mobile terminals and a second traffic resource group for a cell-boundary mobile terminal, and a part of the first traffic resource group is imaginarily divided into a (1−1)-th preliminary traffic resource group, the (1−1)-th preliminary traffic resource group being a preliminary resource group for the cell-boundary mobile terminal. The control resource group is allocated to a control channel for the intra-cell mobile terminal; and a resource of the first traffic resource group or the second traffic resource group is allocated to a traffic channel for the mobile terminal according to inter-cell interference affected to the mobile terminal. Radio resources may be reused in each downlink cell of the OFDM system, the traffic may be rapidly transmitted to the cell boundary mobile terminal, a system capacity may be increased, the cell plane may be easily performed, and the system capacity may not be decreased although the mobile terminal number, locations, and traffic density is not uniform.
