Abstract:
A first device may configure a second device, such as a sidelink receiver, so that an interference protection zone surrounding the second device may be dynamically adjusted in size based, for example, on various objectives and/or use cases recognized by the first device. The interference protection zone may be, for example, an area surrounding the second device, within which neighboring devices may be silenced. Changes to the interference protection zone may be achieved by providing a dynamic clear-to-send (CTS) transmit power scaling parameter, that is different from a pre-assigned constant parameter for CTS power control stored at the second device, to the second device from the first device. The second device may calculate CTS channel power using at least the dynamic CTS transmit power scaling parameter and the received RTS channel power. The second device may send a CTS message in a CTS channel at the calculated CTS channel power.
