## Abstract

Methods, systems, and devices for wireless communications are described for relaying communications from a source device to a destination device via one or more relay devices. Scheduled resource grants may be used to provide resources for the relayed communications, and may provide one or more associated relaying parameters for relayed communications. A source device and relay device may use parameters to determine a relaying priority for multiple communications that are to be relayed. Additionally or alternatively, scheduled resource grants may include energy harvesting (EH) parameters for communications that use the scheduled resources. The EH parameters may include, for example, time-switching energy harvesting parameters that configure a first subset of symbols for data and a second subset of symbols for EH, or power-splitting EH where power of a received signal is split between EH components and decoding components.
