Abstract: Methods and apparatuses are described herein for robust bandwidth part (BWP) approaches to mitigate the impact of high power narrow-band interference. For example, a wireless transmit/receive unit (WTRU) may receive, from a base station (BS), configuration information indicating a plurality of initial bandwidth parts (BWPs). The plurality of initial BWPs may comprise a first initial BWP and a second initial BWP. The first initial BWP and the second initial BWP may be separated from each other in a frequency domain to avoid interference on at least one of the plurality of initial BWPs. The WTRU may send, based on failure to decode a transmission received in the first initial BWP, to the BS, an uplink transmission using the second initial BWP. The uplink transmission may include one or more preambles that are sent using a physical random access channel (PRACH).

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: 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 method for use in a Wireless Transmit/Receive Unit (WTRU). The method comprises: receiving, using an active receiver, system information comprising a first system information set, wherein the first system information set is currently valid for the WTRU; storing the system information; deactivating the active receiver and activating a passive receiver; determining whether a difference between a first parameter in the BSSI and a first parameter in the first system information set is greater than a threshold value, wherein on a condition that the difference is greater than the threshold value, reactivating the active receiver to receive a second system information set as a currently valid system information set for 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: A resonance magnetic coupling (RMC) communication may be enabled between devices. A device may use a discovery mechanism to transmit and exchange information. A device may use the discovery mechanism to establish a RMC communication channel and may determine its parameterization. A device using a RMC communication may transmit a discovery signal to determine channelization and/or properties of the RMC link. The discovery signal may be generated in the form of a beacon transmission. A signal sequence may be employed for a discovery signal. A device using a RMC communication may transmit a sequence of beacon or discovery signals to track characteristics of the RMC link. Beacon scheduling may be used for RMC communications, and the communication channel may not be static and may be a function of distance and orientation. A device using a RMC communication may sense the channel for potential beacon or sequence signals from other devices.
