Web5G NR supports Mini Slot concept which helps in achieving very low latency in data transmission. It supports 2, 4 or 7 OFDM symbols. The figure depicts resource grid of 5G NR with symbols in time axis and subcarriers in frequency axis. 12 subcarriers form one PRB (Physical Resource Block). 5G NR supports 24 to 275 PRBs in a single slot. WebSINR is also measured in UMTS and 5G NR. CQI (Channel Quality Indication) - Instead of expressing the CQI as a received signal quality, the CQI expressed as a data rate that terminal (UE) can support under the actual radio conditions. SINR is used for calculating CQI. In LTE, CQI has only 15 codes. MCS parameter is assigned based on the CQI value.
