This work item presents scenarios for 3 CC downlink intra-band contiguous carrier aggregation. Two CC carrier
aggregation has been a successful mechanism to provide additional bandwidth in some cases. However, there are still
market requirements which require even higher bandwidth. The next logical step in carrier aggregation is to aggregate 3
CCs on the downlink. This work item proposes 3 CC intraband contiguous CA in Band 41. This work item essentially
adds a 3rd DL 10/15/20 MHz component carrier to the previously-approved 2-CC intra-band contiguous CA in Band 41.
A 3rd UL CC is beyond the scope of this WID. The bandwidth options of the additional CC will be the same range of
bandwidths in the approved 2-CC B41 CA (10/15/20 MHz).
The present document was approved at TSG RAN #61. The objective of this work item is to provide specification
support for intra-band contiguous carrier aggregation in LTE TDD Band 41 for 3DL.
The present document provides motivation, requirements and a list of recommended changes to the specifications.
