Question: In NG-RAN UE positioning using Bluetooth beacon assistance data, what types of antenna array configurations can be defined for a Bluetooth beacon, in addition to a generic antenna array?
Option 1: Only a single parameterized antenna array (e.g., linear) can be defined.
Option 2: Two types of parameterized antenna arrays (e.g., linear and rectangular) can be defined.
Option 3: Three types of parameterized antenna arrays (linear, rectangular, or circular) can be defined.
Option 4: The configuration is limited to only a generic antenna array without additional parameterized options.
Explanation: This correct answer reflects the specification's allowance for flexibility in Bluetooth beacon antenna configurations to accommodate various deployment scenarios. Defining linear, rectangular, or circular antenna arrays, in addition to a generic configuration, enables better adaptability to different environments and use cases in NG-RAN UE positioning, enhancing location accuracy and reliability.
