The Radio Resource Control (RRC) protocol is used in UMTS, LTE and 5G on the Air interface. It is a layer 3 (Network Layer) protocol used between UE and Base Station . This protocol is specified by 3GPP in TS 25.331 for UMTS, in TS 36.331 for LTE and in TS 38.331 for 5G New Radio.

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 moreHow many slots are present in 5G subframe?
In this configuration, a subframe has 16 slots in it, it means a radio frame contains 160 slots in it. The number of OFDM symbols within a slot is 14.
Read moreWhat is resource grid in 5G?
– A resource grid is characterized by one subframe in time domain and full carrier bandwidth in the frequency domain . – There are a set of resource grids per transmission direction (uplink or downlink).
