Abstract: The present disclosure relates to a method and apparatus for transmitting and receiving data in a wireless communication system. In particular, the present disclosure relates to a scheduling method and apparatus for transmitting and receiving data in a wireless communication system using a sliding window superposition coding scheme. In the present disclosure, in a wireless communication system, if a UE is located in a cell edge, data throughput can be improved. An eNB using an SWSC scheme can provide fast scheduling. An eNB can provide higher throughput.

Abstract: The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as long term evolution (LTE). The present disclosure relates to signaling for sliding window superposition coding transmission. A method for a first terminal includes receiving, from a base station, first information included in decoding related information on a higher layer signaling, receiving from the base station control information including second information included in the decoding related information, identifying the second information by decoding of the control information, and decoding data transmitted to the second terminal based on the first information and the second information.

Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). 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.
According to various embodiments of the present disclosure, a CQI transmission method of a terminal in a wireless communication system includes: estimating a channel of a serving base station and an interference base station to which sliding-window superposition coding (SWSC) is applied; generating channel quality information (CQI)-related information on the serving base station and the interference base station based on the estimated channel to indicate an achievable rate region; and transmitting the generated CQI-related information. However, the present disclosure is not limited to the above embodiment, and therefore other embodiments are possible.

Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system for supporting higher data rates beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A performance of the existing sliding-window superposition coding (SWSC) is degraded when a wireless channel state is changed due to a large scale fading and a small scale fading. In addition, the performance of the existing SWSC is degraded when channel state information at a receiver is different from that of the real channel. To resolve these problems, a transmitter applies an accurate data transmission rate suitable for a channel state. Therefore, a receiver applies an adaptive SWSC and to reduce a block error rate (BLER) and a hybrid automatic repeat request (HARQ) overhead of the receiver. In addition, to resolve wireless channel state change due to large and small scale fading, the transmitter may use the adaptive transmission method.
