Assuming I have 10 Mhz band for LTE (Upper C Block) and I want to calculate RSRQ with only the reference signal transmitting in the resource blocks - No noise and interference.... based on the formula: N* RSRP / RSSI i would come up with .5 or -3 dB - Based on definition of RSSI, the power seen by the UE would be over the full bandwidth (10 Mhz) which for the reference signal would imply over the 100 Resource elements. However the numerator only multiplies the RSRP by the number of resource blocks which is 50. Why would I get RSRQ of -3 dB when i am only tx the reference signal - it should be 0 dB - the N in terms of resource blocks but not in terms of resource elements does not make sense to me.

Thank you in advance.
