What is BSR and how it work ?
BSR is buffer status report. As we know that DL/UL resource allocation is controlled by eNodeB, so for the planning for resource allocation it is necessary for eNodeB to get to know about the pending data from different UE.
Direction of BSR is from UE to eNodeB, there are three different type of BSR as follows-
1. Long BSR.
2. Short BSR.
3. Truncated BSR.
4. Regular BSR.
5. Periodic BSR.
To understand the difference between Long, short and trucated BSR, it is necessary to know the concept of logical channel and logical channel group.
