Question: What determines the starting point of a Scheduling Request (SR) transmission occasion in a PUCCH when the periodicity is smaller than one slot?
Option 1: The slot number within a frame as defined by the `periodicityAndOffset` configuration.
Option 2: A fixed symbol index within the first slot of the frame.
Option 3: The value of `startingSymbolIndex` provided in the SR configuration.
Option 4: The UE's current HARQ-ACK process number.
Explanation: According to specifications for SR transmission, when periodicity is smaller than one slot, the UE determines the SR transmission occasion start based on a specific symbol index, directly tied to the `startingSymbolIndex` value in the SR configuration, ensuring flexibility based on network needs and UE capabilities.
