Question: What is a key network operation requirement for efficiently supporting small form factor UEs (e.g., sensors, monitoring devices) with limited antenna capability in a 5G network?
Option 1: Enhanced Mobility Management for frequent handovers
Option 2: High-power transmission to compensate for antenna limitations
Option 3: Optimization for UE originated data transfer with reduced signalling overhead for small data bursts
Option 4: Mandatory deployment of multiple antennas on all UEs
Explanation: Small form factor UEs, often with only one antenna due to design constraints, require the network to be optimized for efficient data transfer. This is particularly crucial for devices sending small, intermittent data bursts (e.g., status updates). Reducing signalling overhead before and after these small transmissions avoids wasting resources, minimizes battery drain on the UE, and aligns with 5G's goal of supporting diverse device types efficiently.
