The scope of the report also covers the 2 DL fallback modes for the 3 DL Carrier Aggregation combinations with single UL configuration [2]. These 3 DL/1UL combinations (with 2 DL fallback modes) are listed in table 1-2. In addition, the report also covers the LTE TDD-FDD joint operation including Carrier Aggregation combinations [3], captured in Table 1-3. In addition, the report also covers the 2 DL fallback modes for the 4 DL Carrier Aggregation combinations with single UL configuration. These 4 DL/1UL combinations (with 2 DL fallback modes) are listed in table 1-4.
