Isolation between Macro and Indoor Cell for LTE

[jbada]

Hi Forum,

I would like to ask if someone has a recommendation for isolation between macro cells and indoor cell for LTE respect on typical parameters like RSRP, Dominance and SINR in both direction, that is Indoor-Outdoor and Outdoor-Indoor.
As far I know one of the most important criteria is RSRP like RSRP indoor > RSRP macro + 6dB and RSRP macro > RSRP indorr +6dB

Any documentation, explanation will be welcome

Many thanks
