In 3GPP 36.413 specification mentioned that source enodeB can send HO Cancel message while handover preparation is ongoing or even HO Command message has been received. There may be a number of reasons for HO cancel, please refer cause value IE of HO Cancel message.

One of the reason can be if UE triggers A1 event again after sending measurement for HO(A3/A4/A5 event) then eNB will send HO cancel for ongoing HO preparation.

LTE: What are actions taken at source eNodeB or MME in case of partial resource allocation as part of HO procedure?

When target eNodeB is not able to allocate resource for all the bearers which comes as part of Handover Request message, it sends handover request ack with partial success since "E-RABs Failed to Setup List" is present in HOReqAck message.
What MME or source eNodeB does in that case ? Does any action taken by MME for the E-RABs which failed to setup at target eNodeB or some other actions taken ?
