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: A wireless transmit/receive unit (WTRU) may include one or more antennas and a first transceiver operatively coupled to the antennas. The one or more antennas and the first transceiver may be configured to receive a first signal from a network using zero energy from the WTRU. The one or more antennas and the first transceiver may be further configured to extract energy from the first signal. The first transceiver may be further configured to examine a separation between energy threshold events to decode an energy signature of the first signal. The first transceiver may be further configured to activate a second transceiver operatively coupled to the one or more antennas if the decoded energy signature matches a stored energy signature, wherein the second transceiver is powered by the WTRU. The one or more antennas and the second transceiver may be configured to receive a second signal from the network.

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: Methods, systems, and devices for in-channel narrow-band (NB) companion air interface (CAI) assisted wideband (WB) random access channel (RACH) access. Periodic NB downlink (DL) synchronization sequences are detected. Range information is estimated by measuring the periodic NB DL synchronization sequences; and determining an NB CAI RACH occasion. The range information is transmitted to a gNode B (gNB), or other base station, in a NB CAI RACH procedure. At least one selected WB sequence based on the range information and at least one scheduled WB RACH occasion based on the NB CAI RACH occasion are received from the gNB. A contention free WB RACH procedure is performed based on the received at least one selected WB sequence and the at least one scheduled WB RACH occasion.

Abstract: Systems, methods, and instrumentalities are disclosed herein associated with enabling target localization with bi/multi-static measurements in new radio (NR). Bi-static or multi-static configurations with potential targets may be formed with nodes (e.g., WTRUs, gNBs, etc.) of mobile wireless communication systems, for example, to enable target localization applications. Target localization may be enhanced based on using determined configurations to reduce target localization estimation errors.

Abstract: A method and apparatus are described that provides flexible spectrum usage by using a paired frequency division duplex (FDD) spectrum to enable dynamic access in television white space (TVWS), sub-leased spectrum or unlicensed spectrum, (e.g., industrial, scientific and medical (ISM) bands), in a femto cell environment or the like. Elastic FDD (E-FDD) enables femto cell operation in TVWS, sub-leased spectrum and/or unlicensed spectrum, either simultaneously with licensed spectrum or as an alternate channel to licensed spectrum. E-FDD enables dynamic asymmetric bandwidth allocation for uplink (UL) and downlink (DL) in FDD, and enables variable duplex spacing, (i.e., using FDD with minimum duplex spacing between DL and UL spectrum, or, using hybrid-FDD, (FDD in a time duplexed fashion), when a spectrum gap between the UL and DL spectrum is below a certain minimum threshold. Additionally, the signaling enhancements to implement E-FDD are also provided.

Abstract: Approaches for idle mode operations for wireless transmit/receive units (WTRUs) with zero-energy (ZE) receivers are disclosed herein. A WTRU operating in idle mode, may receive using the main transceiver over a Uu interface, an energy harvesting (EH) configuration for use over a ZE air interface. The main transceiver may be turned off, and the ZE receiver as part of a ZE idle mode operation, may detect, over the ZE air interface, and harvest energy from ZE reference signals. The WTRU may calculate an amount of energy harvested from the ZE reference signals over a first time period. The WTRU may calculate a ZE idle mode operation energy consumption over the first time period. On a condition that the ZE idle mode operation energy consumption is greater than the harvested energy, the main transceiver may be turned on and the WTRU may enter a Uu interface idle mode operation.

Abstract: Method and apparatus for a WTRU to harvest energy from uplink signals of other WTRUs in a wireless network are disclosed. In an example, a method includes sending WTRU location information and determining a mapping between one or more geographical areas and their respective unique geographical radio network temporary identifier (RNTI) (geo-RNTI) and determining a current geo-RNTI of the WTRU based on the WTRU location information. The method may include decoding one or more configuration parameters of a first group of one or more other WTRU in the determined geo-RNTI, switching receive circuitry of the WTRU based on the one or more configuration parameters decoded; and harvesting radio frequency (RF) energy from uplink transmissions of the one or more other WTRUs based on switching of the receive circuitry.
