Question: In a Multi-Standard Radio (MSR) Base Station (BS), how are requirements typically structured in relation to single-Radio Access Technology (RAT) specifications?
Option 1: All MSR requirements are exclusively defined within the single-RAT specifications without any generic MSR requirements.
Option 2: MSR requirements are entirely specified in the MSR document, with no references or dependencies on single-RAT specifications.
Option 3: MSR requirements can be a combination of: (a) generic requirements applying to all RATs, (b) generic requirements with additional RAT-specific requirements from single-RAT specs, and (c) direct application of single-RAT requirements without a generic overlay.
Option 4: The structure of MSR requirements is solely determined by the Band Category, ignoring the type of RAT or generic MSR needs.
Explanation: This option correctly reflects the nuanced approach to specifying MSR requirements. It acknowledges that some requirements are universally applied across all RATs (generic), others may have a base generic requirement with additional specifics from single-RAT specs, and situations where only the single-RAT requirements apply without a generic MSR layer. This structure accommodates the complexity of supporting multiple radio access technologies in a single base station.
