Can UE reject the HO command received in RRC reconfiguration?

Question

If ENB is giving HO command in reconfiguration , for some reason UE wants to reject. Is this valid behavior ?

Answer 1

Yes ue can reject rrc reconfiguration. If ue rejects rrc reconfiguration then ue needs to send rrc re-establishment request to enb.

Answer 2

I agree with Veer. UE triggers RRC re-establishment procedure towards eNodeB (either source or target cell) and it includes re-establishment cause. As per specification, possible causes for re-establishment can be reconfigurationFailure or handoverFailure or otherFailure. UE will choose appropriate cause according to on the going procedure.

Comments

Hi , this is not an HO failure case , UE rejected the RRC reconfiguration which has HO command.  Why UE triggers re-establishment ?Reestablishment is triggered if HO failure but above scenario is not an HO failure, it is HO rejection from UE.
i wanted to know after HO reconfiguration rejection does UE still camps on source cell?

Answer 3

Yes, it's a valid behavior because offered QOS by enB can be negotiated one , so this can be the one of the reason that ue reject HO command msg
