Abstract
A method (40) of antenna array dynamic configuration for 3-Dimension beamforming in wireless network is provided, comprising: determining (41) dynamically a mapping pattern for transforming a physical antenna array into a virtual antenna array based on time-varying downlink or uplink baseband channel statistics, from a set of candidate mapping patterns; and configuring (42) the physical antenna array as different virtual antenna arrays according to the dynamically determined mapping pattern. The corresponding apparatus, antenna array and wireless base station system are also provided. These are used to improve radio transmission bandwidth communication efficiency.
