Question: In a UTRAN Iub interface (Node B Application Part - NBAP), how does a Node B identify resources for a specific frequency in a multi-frequency cell for reporting in procedures like Audit or Resource Status Indication?
Option 1: Using the Cell ID alone, as it uniquely identifies all resources within a cell.
Option 2: Through a combination of the Local Cell ID and a generic Resource Identifier (RI).
Option 3: By including both the Frequency Process Module (FPM) ID and the Local Cell ID in the Local Cell Information IE.
Option 4: Via a dynamically assigned Temporary Resource Identifier (TRI) sent in each procedure message.
Explanation: In UTRAN's NBAP signalling for multi-frequency cells, resources for each frequency are specifically defined by a Frequency Process Module (FPM), identified by a unique FPM ID. To accurately report the status of these resources, both the FPM ID and the Local Cell ID are necessary, ensuring clarity on which frequency's resource status is being reported.
