Polling means check the status of (a device), especially as part of a repeated cycle.

Significance of these variables/timers/counters PDU_WITHOUT_POLL and BYTE_WITHOUT_POLL is to tell the other AMD-RLC peer when to trigger the STATUS report.

Initially the values for these counters will be set to 0 and Upon assembly of a new AMD PDU, the transmitting side of an AM RLC entity will increase the counter to 1.

PDU_WITHOUT_POLL= will count the PDU's that how many PDU's it can allow without asking for the status report.

BYTE_WITHOUT_POLL: will count the number of bytes it can allow without asking the status report.

LTE: What type of data is considered for transparent mode (TM) transmission in LTE RLC ?

RLC is one of the L2 layer in LTE radio protocol stack. It does many functions such as segmentation, re-assembling and along with that it supports various transmissions mode like transparent mode, acknowledgement mode and un-acknowledgement mode.
Now I want to understand for which type of RLC SDUs and PDUs transparent mode transmission is used.
Does the RLC create single RLC entity at cell level or at the UE level or at the bearer level ?

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.
