Radio frequency energy harvesting indication signal

A method of wireless communication, comprising, by a user equipment (UE):

• receiving, from a second device, an energy harvesting indication that indicates a time period when an radio frequency (RF) signal is to be transmitted by the second device to the UE, wherein the energy harvesting indication is included in a paging physical downlink control channel (PDCCH), a connected mode wake up signal, or an idle mode paging early indication signal, wherein the connected mode wake up signal or the idle mode paging early indication signal includes a single bit indicating whether the time period is for communication, energy harvesting, or both;
• and
• harvesting RF energy from the RF signal during the time period.

A method of wireless communication, comprising:

• transmitting, to a user equipment (UE), an energy harvesting indication that indicates a time period when radio frequency (RF) energy is to be available for energy harvesting, wherein the energy harvesting indication is included in a paging physical downlink control channel (PDCCH), a connected mode wake up signal, or an idle mode paging early indication signal, wherein the connected mode wake up signal or the idle mode paging early indication signal includes a single bit indicating whether the time period is for communication, energy harvesting, or both;
• and
• transmitting an RF signal to the UE or another UE during the time period.
