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: 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 for use in a wireless transmit/receive unit (WTRU) configured to communicate through a zero energy (ZE) interface in accordance with an embodiment disclosed herein is provided. The method includes the WTRU receiving, a first positioning reference signal (PRS) resource with parameters characterizing the first PRS and determining the suitability of the first PRS resource for use by the WTRU. The method also includes measuring the phase difference of arrival (PDOA) for available frequency pairs and generating a range estimate based on the PDOA measurement. Further, the method includes the WTRU evaluating a reliability of the PDOA measurement and an accuracy of the range estimate and, on a condition that a sufficient accuracy has been achieved, reporting the range estimate.

Abstract: A method and WTRU to support an in-channel narrowband companion air interface (NB-CAI) assisted wideband (WB) frequency error correction procedure is disclosed. The method may comprise a WTRU sending, via the NB-CAI, a frequency convergence reference signal (FCRS) scheduling request to a network node and receiving, via the NB-CAI, a FCRS scheduling response from the network node. The method may comprise receiving, via a wideband air interface (WB-AI), periodic FCRSs from the network node based on the received FCRS scheduling response and sending, via the NB-CAI, a request to the network node to change a rate of FCRS transmissions. The FCRS scheduling request may comprise range information. The request to change a rate of FCRS transmissions may be based on a convergence indication. The request to change a rate of FCRS transmissions may comprise a configuration identification of a selected FCRS configuration from a set of FCRS configurations.

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.
