Question: In E-UTRA, how is the throughput calculated for multi-stream transmissions (more than one codeword)?
Option 1: The throughput is the average of all data streams (codewords).
Option 2: The throughput is the sum of throughputs of all data streams (codewords).
Option 3: The throughput is determined by the primary codeword only.
Option 4: The throughput calculation varies based on UE category.
Explanation: In E-UTRA, for transmissions involving more than one codeword (multi-stream), the overall throughput is not an average or determined by a single codeword, nor does it depend on the UE category for its calculation method. Instead, it's the cumulative sum of the throughputs of all individual data streams (codewords), ensuring that the total capacity is accurately represented.
