For those used to working in UMTS WCDMA it is equivalent to CPICH RSCP. It is of most importance as it used by the UE for the cell selection and reselection process and is reported to the network to aid in the handover procedure.

RSRP (Reference Signal Received Power), RSRQ (Reference Signal Received Quality) and SINR (Signal to Interference & Noise Ratio). In this particular example, three measurement quantities are used. Of course there are no rules as to how various RF conditions are classified, so different tables will exist but to a great extent you can expect them to align. The source of this table is a EUTRAN vendor and has been complied during the RF tuning process for a major US operator. When it comes to LTE, I came across the above table that presents a good classification.

To aid with performance analysis then, we typically define some ranges of RF measurements that correspond to some typical RF conditions one might find themselves in. It is common sense that the performance of any wireless system has a direct relationship with the RF conditions at the time.
