Methods and apparatus for waveform design and signaling for energy harvesting

The feedback message in both methods may be transmitted as part of a frame that contains other information such as frame format, payload size, end of message indication, request for additional resources indication, . . . etc. The total transmission time must comply with the time slot duration specified by the BS's control message. For example, an EH WTRU receiving a control message polling/enquiring for WTRUs interested in energy harvesting, may decide to include additional information in the feedback frame such as current battery level or expected duration before the battery level reaches a certain threshold. If the configured time slot duration is not sufficient for the feedback of this information, the EH WTRU may then choose a frame format that indicates the current frame as part of a larger message, using an end of message indication bit, and containing a few bits (depending on system implementation, these might be 2, 3, or more bits) that can be used to request additional resources for the next feedback frame transmission.
The two methods described above were discussed in the context of the first scenario identified at the beginning of the section, but they are also applicable (probably with a slight modification) to the other two scenarios.
