MCS (Modulation and Coding Scheme ) defines how many useful bits can be transmitted per Resource Element (RE). MCS depends on radio link quality. The better quality the higher MCS and the more useful data can be transmitted.
Read moreWhat is MCS in wireless?
The Modulation Coding Scheme (MCS) index is an existing industry metric based on several parameters of a Wi-Fi connection between a client device and a wireless access point, including data rate, channel width, and the number of antennas or spatial streams in the device.
Read moreWhat is modulation order in 5G?
Phase shift keying: 5G technology implements quadrature phase shift keying, QPSK as the lowest order modulation format . Although this will provide the slowest data throughput it will also provide the most robust link and as such it can be used when signal levels are low or when interference is high.

For example, for 2 spatial streams, and an 80 MHz channel, to get an MCS of 5 you need at least 24 dBM of SNR or -60 RSSI .16 Eyl 2020
Read moreWhich layer actually does HARQ level error correction?
All Answers (2) In general, HARQ is a physical layer protocol, which combines the use of forward error correction (fast, because it does not involve any retransmission) with retransmission request, when the errors are too severe for FEC to correct them.
Read moreWhat is HARQ explain briefly?
Hybrid automatic repeat request (hybrid ARQ or HARQ) is a combination of high-rate forward error correction (FEC) and automatic repeat request (ARQ) error-control . In standard ARQ, redundant bits are added to data to be transmitted using an error-detecting (ED) code such as a cyclic redundancy check (CRC).

The eNodeB will keep transmitting the same transport block using different RV values until the UE receives an error free transport block or the total retransmission limit occurs. In LTE the total number of HARQ processes which can be initiated at any given time is 8 .
