Abstract: A wireless transmit/receive unit (WTRU) (e.g., a millimeter WTRU (mWTRU)) may receive a first control channel using a first antenna pattern. The WTRU may receive a second control channel using a second antenna pattern. The WTRU may demodulate and decode the first control channel. The WTRU may demodulate and decode the second control channel. The WTRU may determine, using at least one of: the decoded first control channel or the second control channel, beam scheduling information associated with the WTRU and whether the WTRU is scheduled for an mmW segment. The WTRU may form a receive beam using the determined beam scheduling information. The WTRU receive the second control channel using the receive beam. The WTRU determine, by demodulating and decoding the second control channel, dynamic per-TTI scheduling information related to a data channel associated with the second control channel.

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: Procedures, methods, architectures, apparatuses, systems, devices, and computer program products are described that may be implemented in a wireless transmit/receive unit (WTRU) for sidelink (SL) communication. In one representative method, the WTRU estimates a primary direction for a SL transmission. The first WTRU derives a paired direction associated with the primary direction. SL control information (SCI) sensing in the primary and paired directions may be performed to detect SL transmissions and/or reservations from other WTRUs. The WTRU may select a SL resource using any sensed SCI in the primary and paired directions. The WTRU may proceed to transmit SL control and data over the selected SL resource, such as in a SL slot. For example, the transmission of SL control information may include SCI transmission in the primary and paired directions in the same symbols of a slot.

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: Procedures, methods, architectures, apparatuses, systems, devices, and computer program products are disclosed that may be implemented in a wireless transmit/receive unit (WTRU), such as where the WTRU is in an inactive and/or idle (e.g., RRC) state. In one representative method, the WTRU may receive a downlink (DL) small data transmission (SDT) indication with respect to a paging occasion. The WTRU may receive the indicated DL SDT payload which may be multiplexed with a paging record for the paging occasion and/or with one or more configured DL SDT PDSCH resources. Hybrid automatic repeat request (HARQ) feedback information for the DL SDT payload may be transmitted using configured PUCCH resources and/or may be multiplexed with a random access channel (RACH) procedure. The DL SDT payload may be received by the WTRU without transitioning to a connected (e.g., RRC) state.

Abstract: Methods and apparatus for targeted wake-up and frame enhancement for energy harvesting are disclosed. In one embodiment, a method performed by a station (STA) may compromise: receiving, during an energy detection state, a zero energy (ZE) frame from an access point (AP) that indicates a presence of an energy harvesting (EH) window; harvesting energy for a determined time duration during the EH window; and receiving, during an information decoding state, a data portion of the ZE frame based on a current stored energy of the STA being above a first threshold and a signal strength of the received ZE frame being above a second threshold.

Abstract: Methods and apparatuses are described herein for providing Hybrid Automatic Repeat Request (HARQ) techniques for a non-terrestrial network. For example, a wireless transmit/receive unit (WTRU) may transmit, to a satellite base station (BS), uplink (UL) feedback that includes configuration information for redundancy versions (RVs) and cross redundancy versions (cRVs). The WTRU may receive one or more first RVs associated with a first transport block (TB). The WTRU may receive one or more second RVs associated with a second TB and at least one cross redundancy version (cRV) associated with the first TB and second TB. The cRV may include parity bits generated from both the first TB and second TB. If at least one of the first TB or the second TB is unsuccessfully decoded, the WTRU may decode the first TB and second TB jointly based on the at least one cRV.

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.
