LTE: Does all cells belong to the same eNodeB must have the same DRX cycle ?

If my following understanding is correct then please provide your comment/answer.
- S1 setup procedure is done by at eNodeB level rather than a cell level granularity.
- All the cells belong to same eNodeB follow the same DRX configuration.

Concluding from 36.413, eNB sends default paging DRX in S1 setup request to MME. Only one value of DRX is send to MME and only one S1 setup created with one Mme. So all cells belongs to one eNB needs to use same DRX.

Yes all cells belongs to a eNB uses same Paging DRX.

S1setup is performed at eNB level. S1 setup includes TAs of each cells that belongs to same enb with plmn. But it have Paging DRX at eNB level so all cells belong to same enb uses same Paging DRX.

Is there any explicit info associated with your comment in 3GPP? Otherwise how did you infer that result?

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 ?
