An NR CQI value represents a coding scheme and coding efficiency. How many bits does a CQI value reported by a UE have?
An NR CQI value represents a coding scheme and coding efficiency, and they are reported in the form of 8 bits by a UE. According to the official Huawei documentation, 'The 8-bit long CQI value maps to a coding scheme and coding efficiency that can be used for Transport Block (TB) size selection.'
CQI (channel quality indicator) is a value that represents the channel quality of the wireless link between a UE (user equipment) and an eNodeB (base station) in an NR (New Radio) network. The UE reports the CQI value to the eNodeB, which uses it to determine the optimal coding scheme and modulation for the downlink transmissions to that UE.
The CQI value is reported by UE to the eNodeB, it's a value that indicates the channel quality of the link between the UE and the eNodeB. The CQI value is encoded in 8 bits, which allows for a total of 256 different CQI values.
