Description

TECHNICAL FIELD The disclosure relates to a method and apparatus for transmitting and receiving data in a wireless communication system. BACKGROUND ART To meet the increase in demand for wireless data traffic after the commercialization of 4th generation (4G) communication systems, considerable efforts have been made to develop enhanced 5G communication systems. In this regard, 5G communication systems have been referred to as beyond 4G network communication systems or post long-term evolution (LTE) systems. In order to achieve a high data rate, 5G communication systems are being developed to be implemented in a super-high frequency band (millimeter wave (mm Wave)), e.g., a band of 60 GHz. In order to reduce propagation path loss of radio waves and increase a propagation distance of radio waves in millimeter wave frequency bands, in 5G communication systems, discussions are underway about technologies such as beamforming, massive multiple-input multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beamforming, and large-scale antenna. In order to improve system networks for 5G communication systems, various technologies have been developed, e.g., evolved 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 received-interference cancellation. In addition, for 5G communication systems, advanced coding modulation (ACM) technologies such as hybrid frequency-shift keying (FSK) and quadrature amplitude modulation (QAM) (FQAM) and sliding window superposition coding (SWSC), and advanced access technologies such as filter bank multi-carrier (FBMC), non-orthogonal multiple access (NOMA), and sparse code multiple access (SCMA), have been developed. A new radio (NR), i.e., new 5G communication, has been designed such that various services are freely multiplexed in time and frequency resources, and accordingly, waveform/numerology, a reference signal, and the like may be dynamically or freely assigned according to necessity of a corresponding service. To provide an optimum service to a terminal in communication, data transmission optimized via measurement of quality and interference of a channel is important, and thus channel state measurement is mandatory. However, unlike 4G communication in which channel and interference characteristics do not largely change depending on a frequency resource, channel and interference characteristics of a 5G channel largely change depending on a service, and thus a subset of a frequency resource group (FRG) needs to be supported to divide and measure services. In an NR system, types of supported services may be divided in categories of enhanced mobile broadband (eMBB), massive machine type communications (mMTC), and ultra-reliable and low-latency communications (URLLC). The eMBB may be a service aiming at high-speed transmission of high-capacity data, the mMTC may be a service aiming at terminal power minimization and multiple terminal connections, and the URLLC may be a service aiming at high reliability and low delay. Different requirements may be applied depending on types of services applied to the terminal. As such, a plurality of services may be provided to a user in a communication system, and a method for providing the plurality of services according to characteristics so as to provide the plurality of services to the user and an apparatus using the method are required.
