For system network improvement, in 5G communication systems, technologies such as evolved small cell, advanced small cell, cloud radio access network (RAN), ultra-dense network, device-to-device (D2D) communication, wireless backhaul, moving network, cooperative communication, coordinated multi-points (CoMPs), and interference cancellation have been developed.

In a 5G system, advanced coding modulation (ACM) schemes including hybrid frequency-shift keying (FSK) and quadrature amplitude modulation (QAM) modulation (FQAM) and sliding window superposition coding (SWSC), and advanced access schemes including filter bank multi carrier (FBMC), non-orthogonal multiple access (NOMA), and sparse code multiple access (SCMA) have been developed.

In the 5G system, support for various services has been considered when compared to existing 4G systems. For example, most representative services may include mobile ultra-wideband communication (enhanced mobile broadband (eMBB)) services, ultra-reliable and low-latency communication (URLLC) services, massive machine type communication (mMTC), next-generation broadcasting services (evolved multimedia broadcast/multicast services: eMBMS), etc. A system providing the URLLC service may be referred to as an URLLC system, and a system providing the eMBB service may be referred to as an eMBB system. The terms, the service and the system, may be used interchangeably.
