Question: What is the observation period for determining the sample timing difference in E-UTRA for a subcarrier spacing of 0.37 kHz?
Option 1: 0.5 ms
Option 2: 1 ms (same as for 2.5 kHz)
Option 3: 3 ms
Option 4: 6 ms
Explanation: According to the 3GPP E-UTRA specifications, for a specific subcarrier spacing of 0.37 kHz, a longer observation period is required to accurately determine the sample timing difference. This is set at 6 ms, distinguishing it from the periods used for other subcarrier spacings like 2.5 kHz, which uses a 1 ms observation period. This distinction highlights the importance of tailored measurement approaches based on the specific characteristics of the signal being analyzed in wireless communication systems.
