Abstract
There is provided mechanisms for controlling transmission from an antenna panel. The method is performed by a network apparatus. A method comprises performing time-domain beamformed communication with terminal devices served by the network apparatus using the antenna panel split into N>1 subpanels. Each subpanel has two input ports and is fed, via the input ports, by signals and configured to generate beams by application of antenna element weights to its antenna elements. The subpanels are at least phase-wise synchronized with each other. When one and the same signal is fed into the input ports of all the subpanels, signals as transmitted from the subpanels add up coherently to represent a 1-layer transmission by a time reference being shared between the subpanels. The time-domain beamformed communication is performed by the network apparatus using from 1 to 2N layers per symbol of a transmission time interval according to a mapping between the input ports and the signals as transmitted from the subpanels.
