Question: What is the primary focus of specifications related to UTRAN Iur and Iub interfaces for Dedicated Channel (DCH) data streams?
Option 1: Specification of Radio Resource Management for Efficient Handover
Option 2: Definition of Transport Bearers and Corresponding Transport Network Control Plane
Option 3: Optimization of User Equipment (UE) Power Consumption During Idle Mode
Option 4: Introduction of New Modulation Schemes for Enhanced Data Throughput
Explanation: The correct answer accurately reflects the emphasis on specifying transport bearers for DCH data streams and the corresponding Transport Network Control plane for UTRAN Iur and Iub interfaces, highlighting standardized transport mechanisms for efficient and reliable data transmission. Options 1, 3, and 4 are incorrect as they pertain to different aspects of wireless communication.
