Question: For the ACK missed detection requirements specified for PUCCH format 5 in E-UTRA, which of the following configurations is NOT applicable for this requirement?
Option 1: FDD (Frequency Division Duplexing) only
Option 2: SU-MIMO (Single User - Multiple Input Multiple Output) on SCell
Option 3: TDD-FDD CA (Time Division Duplexing - Frequency Division Duplexing Carrier Aggregation)
Option 4: TDD (Time Division Duplexing) only
Explanation: The correct answer is Option 2 because the provided context explicitly mentions that the requirement is applicable for FDD only, TDD only, and TDD-FDD CA, as well as for both PUCCH on PCell (Primary Cell) and PUCCH on SCell (Secondary Cell). However, it does not mention SU-MIMO (Single User - Multiple Input Multiple Output) on SCell as one of the applicable configurations. Additionally, ACK/NACK repetitions are disabled, and DAI based codebook size determination is also disabled, but these do not relate directly to the options provided, reinforcing that Option 2 is the correct choice due to its absence in the listed applicabilities.
