Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a device may receive a first signal in a first set of frequency domain resources. The device may harvest energy using the first signal. The device may receive a second signal in a second set of frequency domain resources. The device may backscatter modulated data using the second signal. Numerous other aspects are described.

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.

Abstract: Aspects of the disclosure provide techniques and apparatuses for using keep-alive signaling for network energy saving in an idle mode. A network entity can transmit a keep-alive signal (KAS) to reduce the energy consumption of a network when the network is in an idle mode. In some aspects, the KAS can be a reduced synchronization signal block (SSB) that is sent more frequently than a full SSB. In some aspects, the KAS can have a different beam sweeping pattern and/or beam width from the full SSB.
