Question: When co-locating an E-UTRA Base Station (BS) with other BS types, what is the assumed coupling loss between transmitter and receiver for interference protection requirements?
Option 1: 30 dB
Option 2: 40 dB
Option 3: 20 dB
Option 4: 50 dB
Explanation: The correct answer is based on the standard assumption for co-location scenarios to ensure effective interference protection between different base station types, including E-UTRA, when they are in close proximity. A 30 dB coupling loss is a commonly referenced value in such contexts, providing a balance between realistic physical separation and the need to mitigate potential interference effectively. This value is particularly relevant when considering the co-location of base stations from various technologies (e.g., GSM, UTRA, NR) with E-UTRA BS, as mentioned.
