    Abstract: Method and apparatus for passive or semi-passive nodes having polarization conversion capability. The apparatus provides, to a passive node or a semi-passive node, an access control indication that indicates support for at least one of a first mode of operation or a second mode of operation. The apparatus monitors for a backscattered signal from the passive node or the semi-passive node that is supported by the access control indication, where the backscattered signal comprises the first mode of operation. The apparatus communicates with the passive node or the semi-passive node in response to the first mode of operation of the backscattered signal actively supported by the access control indication.

    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.
