Question: What action does eNB2 take when it receives a RESOURCE STATUS REQUEST message with the Report Characteristics IE bitmap set to "0" (all bits are set to "0")?
Option 1: eNB2 responds with a RESOURCE STATUS RESPONSE message including an empty Measurement Initiation Result IE.
Option 2: eNB2 initiates a RESOURCE STATUS FAILURE message with the cause set to an appropriate value, e.g., "ReportCharacteristicsEmpty".
Option 3: eNB2 ignores the request and continues with ongoing measurements.
Option 4: eNB2 requests additional information via a new RESOURCE STATUS REQUEST message.
Explanation: According to the specified abnormal conditions for Resource Status Reporting, if the Report Characteristics IE bitmap is set to "0" (indicating all bits are set to "0") in the RESOURCE STATUS REQUEST message, eNB2 is required to initiate a RESOURCE STATUS FAILURE message. This action ensures that inappropriate or incomplete requests are handled properly, maintaining the integrity of the resource status reporting process. The cause for this failure is set to an appropriate value, such as "ReportCharacteristicsEmpty", providing clear feedback on the reason for the failure.
