Question: What are the conditions for a UE to consider the entering condition for Event D1 to be satisfied?
Option 1: When either Inequality D1-1 or Inequality D1-2 is fulfilled.
Option 2: When both Inequality D1-1 and Inequality D1-2 are fulfilled.
Option 3: When Inequality D1-3 or Inequality D1-4 is fulfilled.
Option 4: When either Inequality D1-3 or Inequality D1-4, and at least one of Inequality D1-1 or Inequality D1-2, are fulfilled.
Explanation: According to the specification, the UE considers the entering condition for Event D1 to be satisfied when both conditions D1-1 and D1-2 are fulfilled. This means that the distance between the UE and referenceLocation1 must be above threshold1, and the distance between the UE and referenceLocation2 must be below threshold2, simultaneously.
