Question: For a User Equipment (UE) with bit number 29 of `featureGroupIndicators` set to "1", what is the requirement regarding support for configuration indicated by `logicalChannelSR-Mask` in E-UTRA?
Option 1: It is mandatory to support the configuration indicated by `logicalChannelSR-Mask`.
Option 2: Support for the configuration indicated by `logicalChannelSR-Mask` is optional.
Option 3: The requirement depends on the UE's Radio Resource Control (RRC) protocol version.
Option 4: There is no specific requirement mentioned for UEs with this feature indicator setting.
Explanation: When a User Equipment (UE) has bit number 29 of `featureGroupIndicators` set to "1", it is mandatory for the UE to support the configuration indicated by `logicalChannelSR-Mask`, ensuring consistency in handling Scheduling Requests (SR) across all compliant UEs with this capability, which is crucial for efficient radio resource management in E-UTRA networks.
