Method and arrangements to reconfigure a radio base station in a wireless communication system

摘要

A Radio Base Station (RBS) and method of operating the same are provided. The RBS may enable a fast and flexible reconfiguration of the system from a first configuration to a second confirmation where the RBS is triggered to initiate a system reconfiguration and the reconfiguration is performed by starting a new cell with the wanted new configuration in parallel with the original cell. During a certain time period, both the original and the new cell are available. Thereafter, the original cell is shut down. The time offset between the start up of the new cell and the shut down of the original cell may be long enough to ensure that user equipment associated with the original cell can be handed over or can reselect the new cell. The time offset may be short enough to reduce the interference between the original and new cells.
