Question: In UTRAN Iub interface Node B Application Part (NBAP) signalling, what does the Repetition Period determine for a Physical Channel in terms of Time Slot assignment?
Option 1: The specific Time Slot where the Physical Channel is always located.
Option 2: The duration of each Time Slot allocated to a Physical Channel.
Option 3: The number of Time Slots a Physical Channel can occupy simultaneously.
Option 4: The interval (in Radio Frames or Subframes) after which the same Time Slot assignment scheme repeats for the Physical Channel.
Explanation: The Repetition Period is crucial for understanding how Time Slots are cyclically assigned to Physical Channels. It specifies the cycle length (in Radio Frames for general cases, and in Subframes specifically for 1.28Mcps TDD when configuring E-DCH Non-scheduled Grant Information) after which the exact same pattern of Time Slot assignments to a Physical Channel repeats. This ensures predictable and efficient use of resources in UTRAN networks.
