Abstract
Methods, systems, and devices for wireless communications are described. A user equipment may perform retroreflection on a waveform received from a wireless device (e.g., such as a network entity or a second UE) to assist or perform various operations, such as identifying positioning information of the UE, broadcast signaling, or sidelink relay discovery. For example, the UE may receive control signaling indicating a set of resources during which the UE activates retroreflection communications between the UE and the second wireless device. The UE may monitor the set of resources for a waveform from the second wireless device and transmit a retroreflected signal to the second wireless device based on the received waveform. In this way, the second wireless device may identify a position of the UE based on the retroreflected signal, discover the presence of the UE for broadcast or sidelink relay discovery based on the retroreflected signal, or both.
