Abstract: Techniques are provided for a network-controlled repeater (NCR) to share power during the simultaneous transmission of a control link and backhaul link. When the total power for transmitting via the control link and the backhaul link are below a maximum power for transmission, the NCR can use the calculated transmission powers for transmitting each link. Otherwise, the NCR can apply a relative priority to the links, a default priority to each link, a stepwise reduction of power, or a power sharing factor. A power sharing technique can be based on whether there is overlap between the links on the same time symbol, where the same or different beams are used for each link, and/or whether a priority flag for an access link is being used. These and many other features and examples are described.
