Introduction to 5G NR Modulation Coding Scheme
5G NR MCS (Modulation Coding scheme) is a communication system which can transmit data with high speed, efficiency and reliability. It can also support higher peak speeds for even faster data transfers. The 5G NR (New Radio) MCS (Modulation Coding scheme) is set of parameters used in the most important components of a transmission: a physical layer coding mode, a modulation constellation and a channel coding rate. The MCS is primarily selection based on path loss between the user terminal and the communication base station for data rate selection. In addition, there are also other considerations that are specific to requirements such as mobility or traffic load at the cell. In this paper, we focus mainly on discussion about modulation constellation and channel coding rate, which involves the most significant decision-making factor for 5G NR MCS proposals since it affects the multi-user BER performance significantly. A Modulation and Coding Scheme (MCS) is a set of signaling parameters used by the base station and user equipment in OFDMA, SC-FDMA and NR with 5G NR radio. Each MCS provides different throughput, latency, error probability and other characteristics which are configured depending on the channel condition between the base station and user equipment. The MCS (Modulation Coding Scheme) is a parameter that indicates the data rate of the transmission. For example, a MCS-1 means that all channels are at 1Mbps. The higher the MCS level, the more efficient use of network capacity and spectrum resources. The first release of 5G NR features 1.4 Gbps peak data rate and 50 MHz channel bandwidth, which is 2 to 4 times larger than the current LTE network. 5G NR supports a full duplex uplink, which means that the device can transmit and receive at the same time while using half-duplex LTE networks. In other words, the transmission efficiency increases. 5G NR MCS (Modulation Coding scheme) is a new 5G Modulation Coding scheme standard. It is designed to provide a flexible mechanism to support the various types of 5G services and use cases, e.g., non-standalone (NSA) and standalone (SA). A single 5G NR MCS can be used for different user equipment (UE) types and service categories. 5G NR MCS (Modulation Coding scheme) is a key part of the 5G standard. To provide higher throughput and reduced latency, the 5G NR MCS will use QAM-64 modulation, which is 16-fold increase versus QAM-16 modulation used in LTE. With QAM-64 modulation, each symbol can be mapped to 64 bits of digital signal as opposed to 32 bits per symbol with QAM-16. 5G NR MCS (Modulation Coding scheme) is a key part of the 5G standard.

MCS is the modulation scheme followed by the standards of 3GPP, 4G LTE and Wi-Fi to increase data transfer speed. This scheme will help to improve carrier aggregation and increase mobile speed in 5G.
