Description

Method and apparatus for transmission and reception of signal in a communication system The present invention relates to a communication system and to a method and apparatus for transmitting and receiving downlink, uplink, and sidelink signals. More specifically, it relates to a method for defining a set of control information resources defined for sending control information in a sidelink, a method for terminals performing communication to understand this in common, and a method for mapping sidelink control information signals. According to another example, it relates to a method for setting a bandwidth part (BWP) in a Uulink, which is a communication link with a base station, and a BWP in a sidelink, which is a communication link between terminals, and a method and apparatus for transmitting and receiving signals of a terminal according to the same. Efforts are being made to develop improved 5G ( 5th generation) communication systems or pre-5G communication systems to meet the increasing demand for wireless data traffic following the commercialization of 4G ( 4th generation) communication systems. For this reason, 5G communication systems or pre-5G communication systems are referred to as systems beyond 4G networks or systems following LTE systems. To achieve high data transmission rates, the implementation of 5G communication systems in the mmWave band (e.g., the 60 GHz band) is being considered. In order to mitigate path loss and increase the transmission distance of radio waves in the ultra-high frequency band, beamforming, massive array multiple input/output (massive MIMO), full-dimensional multiple input/output (Full Dimensional MIMO: FD-MIMO), array antenna, analog beam-forming, and large-scale antenna technologies are being discussed in 5G communication systems. In addition, to improve the system's network, technologies such as advanced small cells, advanced small cells, cloud radio access networks (cloud RAN), ultra-dense networks, device-to-device communication (D2D), wireless backhaul, moving networks, cooperative communication, Coordinated Multi-Points (CoMP), and interference cancellation are being developed in 5G communication systems. In addition, 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-centric network where humans generate and consume information into an IoT (Internet of Things) network that processes information by exchanging it among distributed components, such as objects. IoE (Internet of Everything) technology, which combines IoT with Big Data processing technologies through 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 the connection of 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), 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 explained, can also be considered an example of the convergence of 5G and IoT technologies.
