Abstract
A method and an access network node are disclosed for beam control. According to an embodiment, the access network node determines first spatial domain information of a channel between a first terminal device and the access network node, based on second spatial domain information of the channel estimated by uplink signals received previously from the first terminal device at multiple time points. The access network node determines beamforming weights for the first terminal device based on the first spatial domain information.
