Patent ID: 8681738

Claim:
A method of preparing a handoff of a user station in a radio communication system from a first access device to a second access device, comprising: transmitting from the first access device to the user station scheduling and measurement signaling, signal transmission within a connection on a radio interface between the user station and the first access device occurring under control of a data packet scheduler in packet-switched mode; and receiving data packets within a connection in a first frequency range between the first access device and the user station while carrying out at the user station, based on the measurement signaling, measurements of signals in a second frequency range disjoint from the first frequency range, and wherein scheduling of resources by the data packet scheduler includes scheduling of measurements of signals to be performed by a mobile station in the second frequency range during a limited period of time and scheduling of transmissions gaps in the first frequency range, and where data packets are transmitted with a time interval dimensioned for carrying out the measurements.
