Question: In E-UTRA Radio Resource Control (RRC), what is the range of values for the `sensingSubchannelNumber-r15` field within the `MeasSensing-Config-r15` information element?
Option 1: INTEGER (1..10)
Option 2: INTEGER (5..25)
Option 3: INTEGER (0..15)
Option 4: INTEGER (1..20)
Explanation: The correct answer is based on the specific definition of the `MeasSensing-Config-r15` information element, where the `sensingSubchannelNumber-r15` field is explicitly defined as an INTEGER ranging from 1 to 20. This precise range is crucial for configuring sensing measurements in E-UTRA networks, impacting how user equipment (UE) performs sensing operations across different subchannels. Understanding this range is vital for optimizing network performance and UE resource allocation during sensing periods.
