The present document is a technical report for Inter-band Carrier Aggregation for 2DL/1UL under Rel-13 time frame. The purpose is to gather the relevant background information and studies in order to address Inter-band Carrier Aggregation requirements. This TR covers relevant background information and studies in order to address Inter-band Carrier Aggregation (2DL/1UL) requirements for the Rel-13 band combinations in Table 1-1.

  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.

 

 

  This TR contains a general part and band specific combination part. The actual requirements are added to the corresponding technical specifications.
