Abstract
A method performed by a network node, for improving the performance of a handover of a user equipment (UE), wherein the network nodeserves a first cellcomprising one or more UEs. When the network nodehas detected that a Signaling Radio Bearer (SRB) is determined to be scheduled for a UEin handover from the first cellto a second cell, the network nodeincreases the Control Channel Element (CCE) aggregation level in an OFDM-subframe to be sent to the UEin a TTI related to the handover. By increasing the CCE aggregation level during a handover procedure, the effective coding rate of the PDCCH is increased, which leads to a more robust coding and reliability. Thereby the number of unsuccessful handovers and lost service is effectively reduced.
