Question: What is the primary purpose of evaluating In-channel Selectivity (ICS) in a Base Station (BS) receiver within the Evolved Universal Terrestrial Radio Access (E-UTRA) context?
Option 1: To assess the receiver's ability to handle multiple wanted signals simultaneously at different power levels.
Option 2: To measure the receiver's capability to receive a desired signal amidst an interfering E-UTRA signal of higher power spectral density.
Option 3: To determine the maximum throughput achievable without any interference on assigned resource blocks.
Option 4: To evaluate the impact of non-E-UTRA signals on the receiver's performance in a mixed radio environment.
Explanation: In-channel Selectivity (ICS) is specifically designed to test how well a BS receiver can filter out unwanted E-UTRA signals that are stronger than the desired signal, ensuring it meets throughput requirements for a reference measurement channel.
