here the EE of in-building relaying scenario where a non-regenerative relay is
used for relaying the signal of an outdoor BS to an indoor UE and, hence,
the access link (RN-UE link) is more reliable than the donor link (BS to RN
link) since the RN is meant to be close to the UE. Assuming this scenario, ...
