which signaling message is triggered by Ue when it moves frome one sector to another sector of same eNB.

Question

I have a query regarding sectors supported by an eNB. one more related query, how eNB scheduler works across sectors to schedule resources?

Comments

Though I have no idea about the scheduling, check if the following white papers can help you (even if it is not related with your query then also worth to read)

Answer 1

IN LTE ,each sector is a cell.If the UE is in idle mode then cell reselection procedure is triggered.In connected mode HO should be triggered for cell change.
There should be independent MAC Scheduler instances running for each of the Cells.
