LTE-A: Does the radio link failure applicable for secondary cell ?

0 votes
1,025 views

If my understaing is correct then in case of carrier aggregation(CA), an UE can connect to multiple cells. One of the cell is known as primary cell while other cells are known as secondary cells. Primary cell physical layer failure is detected based on the receiving N310 consecutive "out of sync". Is the same case applicable for secondary cells as well ?

As per 36.331... Physical layer monitoring and related autonomous actions do not apply to SCells.

So radio link failure is applicable only for Pcell.

An UE configured for carrier aggregation, may have different radio channel conditions for primary and secondary cells.
I meant to say, primary cell may have strong signal strength at the same time UE may observed secondary cell(s) not too good.
In this case, does the same modulation and coding schemes used for primary and secondary or may use different coding and modulation schemes for different channels for the same sub frame?

I went through 36.331 spec, there are various terms such as Srxlev, Q-hyst and so on are used.
Can someone please give a brief overview of all the terms used during the cell selection and cell re-selection procedure ?
