Abstract
A first radio device may send SL control information to a second radio device. The SL control information indicates at least one radio resource for transmission of a reference signal from the first radio device. The second radio device receives the reference signal. Further, the second radio device may forward the received sidelink control information to one or more other radio devices. Based on the received reference signal, the second radio device estimates quality of a radio channel between the first radio device and the second radio device. The estimated quality of the radio channel, may be used to control an SL radio transmission between the first radio device and the second radio device.
