Increasing robustness of handover signalling by increasing the aggregation level of control channel elements

A network node for handling handover of a UE, wherein the network node is configured to serve at least a first cell comprising a UE, the network node comprising:

• processing circuitry;
• memory containing instructions executable by the processing circuitry whereby the network is operative to:
• determine whether a Signaling Radio Bearer (SRB) is to be scheduled in next Transmission Time Interval (TTI) for the UE involved in the handover;
• and
• increase, when the SRB is to be scheduled for the UE in handover from the first cell to a second cell, a Control Channel Element (CCE) aggregation level in an Orthogonal Frequency Division Multiplexing (OFDM) subframe sent to the UE in the TTI related to the handover, wherein the instructions are such that the network node is operative to increase the CCE aggregation level by increasing the number of CCEs assigned to a Physical Downlink Control Channel (PDCCH) of the UE in the OFDM-subframe.
