DEVICE TRIGGERING BACKSCATTER COMMUNICATIONS

Methods, systems, and devices for wireless communications are described. Described techniques provide for signaling for configuring energy scheduling requests or communications scheduling requests from a semi-passive user equipment (UE) to the network. A semi-passive UE may transmit a message indicating a UE class type to a serving network entity (e.g., indicating that the UE is a semi-passive UE). The network entity may transmit control signaling indicating a configuration for the UE to transmit energy scheduling requests or communications scheduling requests. The UE may transmit an energy scheduling request or communications scheduling request in accordance with the configuration. In response to an energy scheduling request, the network entity may indicate a resource for an energy transfer signal, and the UE may monitor for and receive an energy transfer signal in the indicated resource. In response to a communications scheduling request, the network entity may indicate a resource for a data transmission.
