1. A method for communicating in a wireless communication network, the wireless communication network comprising a plurality of base stations and at least one mobile communication unit, wherein the mobile communication unit is moving at speeds above the limit that is allowable in LTE standard, the mobile communication unit comprising a transceiver component, a first Doppler compensation component, and a measurement component, wherein the first Doppler compensation component is adapted to compensate the Doppler shift of signals being exchanged between a base station of the plurality of base stations and the transceiver component, wherein the method comprises:
exchanging data between the transceiver component and a first base station of the plurality of base stations, wherein the first Doppler compensation component compensates the Doppler shift of signals carrying the data by using a first Doppler compensation value; initiating a measurement by transmitting a first signal from the transceiver component to the measurement component; transmitting a second signal from the measurement component to the transceiver component, the second signal being indicative of measurement values being related to at least one second base station of the plurality of base stations; transmitting a measurement report from the transceiver component to the first base station, the measurement report comprising the measurement values of the measurement; determining if a handover procedure from the first base station to a target base station of the at least one second base station is initiated by the first base station; transmitting a third signal from the first base station to the transceiver component, if the first base station has determined to perform the handover procedure to the target base station, the third signal being indicative of initiating the handover procedure; transmitting a fourth signal from the transceiver component to the measurement component, the fourth signal being indicative of the target base station, if the first base station has determined to perform the handover procedure to the target base station; transmitting a fifth signal from the measurement component to the first Doppler compensation component, the fifth signal being indicative of changing the first Doppler compensation value to a second Doppler compensation value, the second Doppler compensation value being adapted to compensate the Doppler shift of signals being exchanged between the transceiver component and the target base station, if the first base station has determined to perform the handover procedure to the target base station; and performing a handover procedure if the first base station has determined to perform a handover procedure to the target base station. |
