I am not sure but somewhere I saw it RACH-Less Handover is possible in synchronized network. It seems Intel invented this mechanism and have patent rights.

What is the behavior if ENB gives less grant in RACH response ?

How UE sends MSG3 in less grant? Will it wait for NEB to give grant or UE does one more RACH?

How many times UE can send rach when ue try to sync at target enb during HO

Suppose UE have mobility parameters for intra LTE HO . UE try to sync with target eNB to confirm HO completion. So UE performs rach with target eNB. Suppose rach is not getting successful then how many time UE will perform rach at target eNB .

What will be the RNTI value in RAR for Contention free HO RACH?

Handover RACH will be initiated as Contention free, RNTI will be included in Mobility info. But while doing RACH What will be the RNTI value included in RAR? Will this be same as Mobility RNTI?

LTE: Is it possible during MBMS data transmission few of the eNodeBs have less MBMS resources compare to others ?

One question came out and want to get answer for that just to avoid assumptions what I have.
A multiple MBMS services are being transmitted over the air through eNodeBs belong to one MBSFN Area. Here I considered all the eNodeBs belongs to that particular MBSFN area have maximum six sub frames of a radio frame to broadcast the content and all eNodeBs are doing.
In between some of the eNodeBs belong to same MBSFN Area get congested and out of 6 sub frames only two subframes are being used in those eNodeB.
My first question where exactly things will be affected ?
Another question, MBMS-GW will be sending data in same speed with same SYNC information. Since few eNodeBs are congested then how data will be transmitted ? Segmentation at eNodeB RLC may affect User experience since UE combines the data in MBMS case from all the neighboring eNodeBs and get better result in term of quality.
If one eNodeB is sending data without segmentation and the other one is sending with segmentation then How UE RLC will behave and what will be the user experience ?

Please ignore these question if segmentation and reassembling is not applicable for MBMS data transmission at RLC.
