1. A wireless transmit/receive unit (WTRU) comprising:
a main transceiver;
a zero-energy (ZE) receiver; and
a processor, wherein
the main transceiver and the processor are configured to:
receive, over a Uu interface, information indicating an energy harvesting (EH) configuration for use over a ZE air interface; and
turn off the main transceiver;
the ZE receiver and the processor are configured to:
in accordance with the EH configuration, harvest energy from ZE signals detected over the ZE air interface, wherein each of the ZE signals includes a power-optimized waveform (POW) part and an information bearing part, and wherein the energy is harvested based on the POW part; and
on a condition that an energy consumption over a first time period is greater than an amount of the harvested energy over the first time period and a measured performance value is greater than a first threshold, continue harvesting energy from ZE signals detected over the ZE air interface.
