LTE Protocol Stack: RADIO LINK FAILURE

Detection of Radio Link Failure:

-When from RLC the maximum number of retransmissions reached -When Random Access problem indication from MAC while nither T300, T301, T304 and nor T311 running.

-Physical Layer receive N310 consecutive "out-sync" indication then RRC start the timer T310.

Recovery from Radio Link Failure:

If Physical Layer receive N311 consecutive "in-sync" indication with in the T310,
then,
UE resumes the RRC connection.
Else,
It perform RRC connection re-establishment when AS Security is active.

Else,
Leave the RRC connection with release cause 'other'
