Question: What is the maximum allowed Transmission Accuracy Error (TAE) for intra-band contiguous carrier aggregation in E-UTRA, with or without MIMO or TX diversity?
Option 1: 65 ns
Option 2: 130 ns
Option 3: 260 ns
Option 4: 500 ns
Explanation: In E-UTRA (Evolved Universal Terrestrial Radio Access) systems, maintaining precise transmission timing is crucial for efficient carrier aggregation. For intra-band contiguous carrier aggregation, whether employing MIMO (Multiple Input Multiple Output), TX diversity, or neither, the standard dictates a specific maximum tolerance to ensure coherent and effective signal transmission across aggregated carriers. The correct limit for TAE in this scenario is 130 ns, striking a balance between technical feasibility and performance requirements. This threshold supports the seamless integration of contiguous frequency bands, enhancing overall network capacity and user experience without compromising on signal integrity.
