Antenna array system network planning, communication network and method for forwarding radio signals with configurable forms beam pattern independently using local knowledge

摘要

An antenna array (1) comprising a digital radio interface (DRI) and a plurality of antenna elements (11-1, 11-2, ..., 11-j) for forwarding radio signals to a cell ( 10) of a mobile communication network (500) comprising the antenna array (1): - a plurality of vectors beamforming uplink (20u) adapted to form a plurality of beam shapes uplink in where one single (22u) of the plurality of beamforming vectors uplink (20u) comprises uplink factors (cu-1, cu-2, ..., cu-j) for the antenna elements (11 -1, 11-2, ..., 11-j) describing an individual of the plurality of ways of uplink beam; - a plurality of vectors beamforming downlink (20d) adapted to form a plurality of beam shapes downlink, wherein one single (22d) of the plurality of vectors beamforming downlink (20d) it comprises factors downlink (cD-1, cD-2, ..., cd-j) of the antenna elements (11-1, 11-2, ..., 11- j) describing an individual of plurality of forms downlink beam; where uplink factors (cu-1, cu-2, ... cu-j) factors and downlink (CD-1, CD-2, ... cd-j) are provided to the interface digital radio (DRI) and wherein at least one of the factors (cu-1, cu-2, ..., cu-j) individual one uplink (22u) of the plurality of beamforming vectors uplink (20u) and downlink factors (cD-1, cD-2, ..., cd-j) of the individual one (22d) of the plurality of beamforming vectors downlink (20d) they are independently controllable to provide different forms of uplink beam and forms the downlink beam.
