Communication time frame for energy harvesting device

A second device for wireless communication, comprising:

• a memory;
• and
• one or more processors, coupled to the memory, configured to:
• receive a message indicating that a first device is operating on intermittently available energy harvested from outside the first device;
• transmit a low-power wakeup signal (WUS);
• receive, in response to transmitting the WUS, an indication that the first device is capable of supporting continuous transmission and reception during a time frame having a configured duration;
• and
• communicate with the first device during the time frame.

A method of wireless communication performed by a first device, comprising:

• transmitting a message indicating that the first device is operating on intermittently available energy harvested from outside the first device;
• receiving a low-power wakeup signal (WUS);
• transmitting, based at least in part on an energy harvesting state of the first device, an indication that the first device is capable of supporting continuous transmission and reception during a time frame having a configured duration;
• and
• communicating during the time frame.
