Claim:
1. A method of handing over a wireless device moving at a high speed from a source base station to a target base station, comprising: measuring a speed of the wireless device; estimating a channel quality based on a channel quality index report from the wireless device; and depending on the measured speed and the estimated channel quality, signaling one or more candidate base stations to coordinate with the source base station for transmitting a handover command to the wireless device, wherein the signaling requests the one or more candidate base stations to transmit the handover command to the wireless device for handing over the wireless device from the source base station to the target base station, wherein the one or more candidate base stations include at least one base station other than the target base station and are included in a recent measurement report from the wireless device, wherein signaling the one or more candidate base stations to coordinate with the source base station for transmitting a handover command based on the measured speed and the estimated channel quality comprises signaling the one or more candidate base stations to coordinate with the source base station when the measured speed value is larger than a predetermined speed threshold and the estimated channel quality value is lower than a first predetermined channel quality threshold.
