Description

Control Information Transmission Method and Apparatus in Wireless Cellular Communication System The present invention relates to a wireless communication system, and more specifically, to a method and apparatus for smoothly providing services in a communication system. More specifically, it relates to a method and apparatus for transmitting control information within a communication system. Efforts are being made to develop improved 5G communication systems or pre-5G communication systems to meet the increasing demand for wireless data traffic following the commercialization of 4G communication systems. For this reason, 5G communication systems or pre-5G communication systems are referred to as systems beyond 4G networks or systems after LTE systems. To achieve high data transmission rates, 5G communication systems are being considered for implementation in the mmWave band (e.g., the 60 GHz band). To mitigate path loss and increase the transmission distance of radio waves in the mmWave band, beamforming, massive MIMO, full Dimensional MIMO (FD-MIMO), array antenna, analog beamforming, and large-scale antenna technologies are being discussed for 5G communication systems. In addition, to improve the network of the system, technologies such as advanced small cell, advanced small cell, cloud radio access network (cloud RAN), ultra-dense network, device-to-device communication (D2D), wireless backhaul, moving network, cooperative communication, CoMP (coordinated multi-points), and interference cancellation are being developed in 5G communication systems. Furthermore, advanced coding modulation (ACM) methods such as FQAM (hybrid FSK and QAM modulation) and SWSC (sliding window superposition coding), as well as advanced access technologies such as FBMC (filter bank multi-carrier), NOMA (non-orthogonal multiple access), and SCMA (sparse code multiple access) are being developed in 5G systems. Meanwhile, the Internet is evolving from a human-centered network where humans generate and consume information into an IoT (Internet of Things) network that exchanges and processes information among distributed components, such as objects. Internet of Everything (IoE) technology, which combines IoT with big data processing techniques via connections with cloud servers, is also emerging. To implement IoT, technological elements such as sensing technology, wired and wireless communication and network infrastructure, service interface technology, and security technology are required; consequently, technologies such as sensor networks, machine-to-machine (M2M) communication, and machine-type communication (MTC) are currently being researched to facilitate connections between objects. In an IoT environment, intelligent IT services that create new value for human life by collecting and analyzing data generated from connected objects can be provided. Through the convergence and integration of existing IT technologies with various industries, IoT can be applied to fields such as smart homes, smart buildings, smart cities, smart or connected cars, smart grids, healthcare, smart home appliances, and advanced medical services. Accordingly, various attempts are being made to apply 5G communication systems to IoT networks. For example, technologies such as sensor networks, machine-to-machine (M2M) communication, and machine-type communication (MTC) are being implemented using 5G communication techniques such as beamforming, MIMO, and array antennas. The application of cloud RAN as a big data processing technology, as previously described, can also be considered an example of the convergence of 5G and IoT technologies. 5G systems are considering support for a wider variety of services compared to existing 4G systems. For example, the most representative services may include enhanced mobile broadband (eMBB), ultra-reliable and low-latency communication (URLLC), massive machine-type communication (mMTC), and evolved multimedia broadcast/multicast service (eMBMS). Furthermore, a system providing the aforementioned URLLC service may be referred to as a URLLC system, a system providing eMBB service as an eMBB system, and a system providing mMTC service as an mMTC system. Additionally, the terms "service" and "system" may be used interchangeably. Figure 1 is a diagram showing the downlink time-frequency domain transmission structure of an LTE or LTE-A system.
