Within the LTE network, different eNodeBs can be deployed with the different bandwidth configuration. Few eNodeBs may be deployed with 10 MHz and few with the 20 MHz. Now I have two questions here.
1. Is it necessary all the cells should have same bandwidth deployment ? If answer is yes then ignore the second question.
2. If cells of the same MBSFN area can have different deployment bandwidth then they would have different amount of multicast resources and what if when a cell exhaust with the allocated MBMS radio resources ? What corrective action MCE should take in this case when few cells of a MBSFN area does not enough room to accommodate new services and other set of cells within the same MBSFN area can serve ?
