Link loss between the indoor cpe and eNB

Hello ! We are observing a problem with the link loss between the indoor cpe and 10w eNB . Indoor cpe has folowing conditions:
Bandwidth
10 MHz
RSSI
-69 dBm
RSRP0
-104.22 dBm
RSRP1
-104.92 dBm
RSRQ
-8.29 dB
SINR
14.98 dB
TX Power
19 dBm
We see the packet loss, when we try to upload a file . The link is down for 30 -60 sec . So we need eNB settings to avoid link drops, when the ping delay reaches more than 2000 ms
