RSRP Bad but SINR and RSRQ good

How to face an issue RSRP Bad but SINR and RSRQ good. my distance from site is 300m :

Low RSSI/RSCP but have a good SINR/RSRQ in such a short distance from site. This problem can be related to a couple things that I can think of.
1. sweep your antenna system to check if there is any defect(s) such as bad antenna, lines, connectors, etc. All these can contribute to low RSRP
2. if the sweep measurement is good, might want to check out tilt and/or investigate tilts to see if there is something that may alter the antenna pattern.
3. Check your power setting just in case if it was set to very minimal level.
if there is no obstacles towards the sector so antenna issue is suspected ,cross partial, vswr.
