DETERMINATION OF A PREFERRED BEAM IN A CELLULAR COMMUNICATION NETWORK EMPLOYING SIGNAL BEAM-FORMING

摘要

A method for acquiring an indication of a preferred beam of a wireless communication device is disclosed. The method is performed in a network node of a cellular communication network. The network node is adapted to support a plurality of beams of a signal beamforming scheme and to communicate with the wireless communication device using at least one beam of the plurality of beams. The method comprises acquiring a beam power setting of the plurality of beams. The beam power setting comprises a power offset being applied to at least one beam of the plurality of beams, the power offset being relative to a nominal power setting of the plurality of beams. The method also comprises transmitting (to the wireless communication device) a message indicative of the beam power setting, transmitting measurement signals, and receiving (from the wireless communication device) a report indicative of the preferred beam, wherein the preferred beam is determined by the wireless communication device based on the measurement signals and the beam power setting.
