    Abstract: Methods and apparatus for waveform design and signaling for energy harvesting (EH) in a wireless network are disclosed. In an example, a method includes receiving a control message including a contention-based backscattering configuration, determining parameters for transmitting a feedback within a contention-based transmission window based on the contention-based backscattering configuration, detecting feedback transmissions sent by other WTRUs within the contention-based transmission window, wherein each feedback transmission includes an EH capability indication, determining whether an EH capability detected from the feedback transmissions matches the EH capability of the WTRU, if a matched EH capability is detected from the feedback transmissions within the contention-based transmission window, delaying a transmission of the feedback, and if no matched EH capability is detected from the feedback transmissions within the contention-based transmission window, transmitting the feedback using the determined parameters.

    Abstract: Systems, methods, and devices for wireless transmissions based on backscattering. A backscatter indication message (BID) is received from an access point (AP). An interrogation signal is received. Uplink data is transmitted to the AP based on the BID and the interrogation signal. In some implementations, the interrogation signal is received from the AP. In some implementations, the BID indicates a backscatter duration, and the uplink data is transmitted to the AP for the backscatter duration. In some implementations, the uplink data is transmitted to the AP concurrently with receiving the interrogation signal. In some implementations, energy is harvested from the interrogation signal. In some implementations, the uplink data is transmitted to the AP subsequent to the interrogation signal, based on the energy harvested from the interrogation signal. In some implementations, the interrogation signal includes a compensation signal based on channel conditions and/or based on backscattering from the WTRU.

    Abstract: A wireless transmit/receive unit, WTRU, may include an Energy Harvesting device, EH, a Zero Energy transceiver, ZE, and a main transceiver. The WTRU may initialize operation using the main transceiver, and receive beam detection configuration and mapping information. The WTRU may initialize beam (re-) selection procedure using the ZE transceiver, and use the received beam detection configuration to determine detectable beam IDs. and use the received mapping information to retrieve EH signaling configuration. The WTRU determines expected EH performance for each detected beam, and selects the beam with best expected EH performance. On condition that the WTRU determines necessity of dynamic EH signaling for the selected beam, it proceeds with presence declaration procedure to request optimized dynamic EH signaling. The WTRU utilizes control signaling channel parameters to dynamically receive optimized EH signal configuration, and configures its EH circuitry, and harvests energy.

    Abstract: Procedures, methods, architectures, apparatuses, systems, devices, and computer program products directed to low-power proximity-based service paging for multi-carrier side-link (SL) communications are described. A first wireless transmit and receive unit (WTRU) may receive, from a second WTRU a request message indicating a set of SL monitoring occasions to be monitored, wherein the set of SL monitoring occasions may be associated with a SL service. The first WTRU may receive one or more transmissions indicating whether the second WTRU is being paged for the SL service. On a condition that the second WTRU is being paged for the SL service, the first WTRU may receive one or more SL messages associated with the SL service and directed to the second WTRU. The first WTRU may transmit to the second WTRU, SL paging information indicating availability of the received one or more SL messages.
