Hi,

Carrier aggregation is used to improve data rate for DL and UL.
In laymen term - single ENB will have 100Rb's(20Mhz) and can achieve max of 150Mbps, in carrier aggregation single ENB will handle 5cells which 5 * 100RB's (each 20Mhz) which is 500RB's and can achieve 5 * 150Mbps.

ENB RRM should be configured with all these 5CC, and all CC should be aware of this configuration. UE will get these CC information Via RRC signaling secondary cell addition/modification Once these cells are added and activated then ENB MAC will start scheduling these CC together for an UE. UE will start listening on all these activated cell for an DL data and UL grant. ENB MAC will have cross scheduler to handle this multiple CC scheduling.

Can anyone please explain MBSFN synchronization Area ,MBSFN area and MBSFN service area ?
How they are mapped to each other ?

When BMSC server initiates a service to broadcast, it provides service Id using the TMGI (temporary mobile group Id) and the area i.e MBMS service area. Once MME forwards this information to MCE, how MCE maps this received MBMS service area to MBSFN Area(s) ? How MCE decides on MCCH related BCCH configuration during the M2 Setup request ? In M2 setup request, eNodeB sends the list of serving MBMS service areas per cell to MCE but how MCE decides which cell is going to be part of a particular MBSFN Area. ?
