Abstract
A method performed by a wireless communication device for reducing handover delay, wherein the wireless communication device is arranged to operate in a cellular communication system and to operate in a cell using unlicensed spectrum. The method includes receiving a downlink, DL, signal from network node operating a neighbouring cell operating in the unlicensed spectrum, wherein the DL signal includes a discovery reference signal, DRS, subframe, storing data associated with the DRS subframe, receiving a handover command from a network node operating a serving cell where the neighbouring cell is a target cell, and performing a random access procedure for handover to the target cell. A device performing the method and a computer program for implementing the method are also disclosed.
