    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.

    Abstract translation: 本公开涉及用于支持超过第四代（4G）通信系统（例如长期演进（LTE））的更高数据速率的前5代（5G）或5G通信系统。 当无线信道状态由于大规模衰落和小规模衰落而改变时，现有的滑动窗口叠加编码（SWSC）的性能下降。 此外，当接收机的信道状态信息与真实信道的信道状态信息不同时，现有的SWSC的性能下降。 为了解决这些问题，发射机应用适合于信道状态的精确数据传输速率。 因此，接收机应用自适应SWSC并减少接收机的块错误率（BLER）和混合自动重传请求（HARQ）开销。 此外，为了解决由于大小衰落衰落引起的无线信道状态变化，发射机可以使用自适应传输方法。
