Question: What is the primary purpose of the 'multiNS-Pmax-r13' field in UE radio access capabilities, as related to NB-IoT cells?
Option 1: To indicate UE support for mechanisms broadcasting NS-PmaxList for efficient power management.
Option 2: To enable UE compatibility with LTE-M networks for low-bandwidth applications.
Option 3: To define the maximum transmission power for UEs in a multi-carrier aggregation scenario.
Option 4: To specify the minimum required signal strength for handover decisions in heterogeneous networks.
Explanation: The correct answer highlights the field's purpose in relation to NB-IoT cells broadcasting NS-PmaxList, crucial for efficient power management and resource allocation in low-power wide-area networks (LPWANs) like NB-IoT. The other options are incorrect as they refer to unrelated technologies, features, or misinterpret the field's application context.
