If several carriers are to be selected from multiple carriers for flexible aggregation, enable LAOFD-070201 Flexible CA from Multiple Carriers.
In addition, LAOFD-070201 Flexible CA from Multiple Carriers requires that
LAOFD-001001 LTE-A Introduction and optionally LAOFD-001002 Carrier Aggregation for Downlink 2CC in 40MHz be enabled. For the deployment scenarios for the two prerequisite features, see 6.1 When to Use LAOFD-001001 and LAOFD-001002.
7.2 Required Information

7.3 Planning
RF Planning
For details about RF planning, see 6.3 Planning.
Network Planning
l If the live network uses multiple frequency bands, no frequency needs to be added to the network plan.
l If the live network uses only one or two frequencies, deploy more frequencies.
Hardware Planning
7.4 Deployment
Deploy this CA feature on a network with at least three operating frequencies. For details about how to deploy a multi-carrier network, see Cell Management.
7.4.1 Requirements
Operating Environment, NEs, and Transmission Networking
The requirements described in 6.4.1 Requirements must be fulfilled. In addition, the EPC must meet the following requirement:
To allow 2CC aggregation to reach a peak data rate of 300 Mbit/s in 2x2 MIMO scenarios, the maximum bit rate that the UE subscribes to in the EPC must be greater than or equal to 300 Mbit/s.
License
Deploying LAOFD-070201 Flexible CA from Multiple Carriers requires the following licenses:
l In CA-group-based configuration mode
In a CA group with more than two cells, each cell requires one sales unit of the license for LAOFD-070201 Flexible CA from Multiple Carriers and one sales unit of the license for LAOFD-001001 LTE-A Introduction.
If the total bandwidth of a cell and any other cell in the CA group is between 20 MHz and 40 MHz (including 40 MHz), the cell requires one sales unit of the license for LAOFD-001002 Carrier Aggregation for Downlink 2CC in 40MHz.
NOTE
l If any license is insufficient, a CA group with cells added does not take effect. However, the original CA group still works. In this case, the eNodeB reports ALM-26819 Data
Configuration Exceeding Licensed Limit.
l If the license for LAOFD-070201 Flexible CA from Multiple Carriers is insufficient in an eNodeB and FreqCfgSwitch under the ENodeBAlgoSwitch.CaAlgoSwitch parameter is set on and then off, none of the cells in a CA group that includes more than two cells takes effect. In addition, the eNodeB reports ALM-26819 Data Configuration Exceeding Licensed Limit. l In frequency-based or adaptive configuration mode
If a cell and its intra-BBU CA partners (either PCell or SCell) form a cell set that covers three or more frequencies, the cell requires one sales unit of the license for
LAOFD-070201 Flexible CA from Multiple Carriers and one sales unit of the license for LAOFD-001001 LTE-A Introduction.
If the total bandwidth of a cell and any other cell in the set is between 20 MHz and 40 MHz (including 40 MHz), the cell requires one sales unit of the license for

7.4.2 Data Preparation

7.4.3 Precautions
For details, see 6.4.3 Precautions.
7.4.4 Hardware Adjustment
l If BBU3900 is used, LBBPd or UBBP boards must be installed in slots 2 and 3. If CA is performed on two boards in other slots, CA cell data still travels through slots 2 and 3. As a result, more backplane bandwidth of slots 2 and 3 is required, and CA can take effect in fewer cells.
l If BBU3910 is used, there is no requirement on the board positions.
7.4.5 Activation
l In CA-group-based configuration mode, perform the MML-based procedure described in 6.4.5 Activation with the following exceptions: Add three cells to the CA group in step 3, and configure two candidate SCells for each PCell in step 4.
l In frequency-based or adaptive configuration mode, perform the MML-based procedure described in 6.4.5 Activation with the following exception: Add at least two candidate SCCs and set their attributes for each candidate PCC in step 3.
7.4.6 Activation Observation
For details, see 6.4.6 Activation Observation.
7.4.7 Deactivation
l In CA-group-based configuration mode, perform step 3 of the MML-based configuration described in 6.4.7 Deactivation to delete one cell from a CA group so that the CA group includes only two cells.
l In frequency-based configuration mode, perform step 1 of the MML-based configuration described in 6.4.7 Deactivation to delete candidate SCCs so that each PCC is
accompanied by only one candidate SCC.
l In adaptive configuration mode, perform step 2 of the MML-based configuration described in 6.4.7 Deactivation to delete candidate SCCs so that each PCC is accompanied by only one candidate SCC.
