ABSTRACT:
The invention relates to methods for handling a bidirectional connection involving a mobile station in a cellular mobile radio communication system having adjacent cells of substantially different sizes, wherein the mobile station estimates the strength of radio signals received from base stations for cells of different sizes, the signal strength of radio signals received from the mobile station by base stations for cells of different sizes are estimated, decisions on which base station(s) should be responsible for an uplink channel of a bidirectional connection are based on uplink parameters including estimated strength for signals received at base stations, the signal strength at the base station(s) responsible for the uplink channel is used for controlling the output power of the mobile station, and decisions on which base station(s) should be responsible for the downlink channel of a bidirectional connection are based on downlink parameters including estimated strength of radio signals from base stations received at the mobile station.
