摘要： The present disclosure relates to a communication method and system for converging a 5G communication system for supporting higher data rates beyond a 4G system with an IoT technology. The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present disclosure can reduces a peak-to-average power ration (PAPR) by performing time domain cyclic filtering. Further, a data rate or coverage can be improved by selectively transmitting transmission waveforms through cyclic prefix (CP)-orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform-spread-OFDM (DFT-s-OFDM).

摘要： The present disclosure relates to a 5G or pre-5G communication system which will be provided in order to support a higher data transmission rate than in 4G communication systems such as LTE. A method at a relay node according to one example of the present invention is a hybrid automatic repeat request method at the relay node in a relay wireless communication system using a compress-and-forward (CF) scheme, and may comprise the steps of: when receiving data from a previous node, performing mesh quantization so as to have redundant information at the time of quantization for transmitting, to a next node, the data received from the previous node; transmitting to the next node by channel-coding only an amount transmittable to a channel set for transmitting to the next node from upper information among the quantized information; and when receiving negative acknowledgement (NACK) from the next node, retransmitting to the next node by channel-coding only an amount transmittable to the set channel among the other information which is not transmitted among the quantized information.

摘要： The present disclosure relates to a method and device for providing different services in a mobile communication system. In an embodiment, a base station sets interference influence information including information about interference of a second signal of a second system using a second TTI with regard to a first signal of a first system using a first transmission time interval (TTI). Also, the base station transmits the first signal of the first system to a terminal, and transmits the interference influence information to the terminal in a predetermined time. In a situation where different services coexist, an HARQ retransmission technique is provided for effectively overcoming a transmission failure caused by influence of interference between services.
