The present document is a technical report of the LTE Advanced Carrier Aggregation in Band 40 for 3DL work item
which was approved at TSG RAN #63 [RP-140145]. The objective of this work item is to provide specification support for intra-band contiguous carrier aggregation in LTE TDD Band 40 for 3DL.
The report provides motivation, requirements and a list of recommended changes to the specifications.
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 intra-band contiguous CA in Band 40. This work item essentially
adds a 3rd DL 10//20MHz component carrier. The number of uplink CC is up to 2. The 3 CCs for UL is beyond of this
