Abstract: A wireless transmit/receive unit (WTRU) is configured to perform a method that comprises receiving a downlink control information (DCI) that schedules a first physical downlink shared channel (PDSCH) transmission and a second PDSCH transmission. The DCI comprises an indication of a beam identifier. The DCI indicates a time domain resource information for the first PDSCH transmission and the second PDSCH transmission. The method comprises receiving the first PDSCH transmission using a first beam. The first beam is a beam used for receiving a control channel transmission. The method comprises receiving the second PDSCH transmission using a second beam. The second beam is a beam of the beam identifier indicated in the DCI.

Abstract: Procedures, methods, architectures, apparatuses, systems, devices, and computer program products are described for the synchronization of multiple traffic flows of information such as protocol data unit (PDU) flows associated with applications and/or services. In an example embodiment, a device may receive one or more forwarding configurations to use when transmitting data in multiple flows. The forwarding configurations may lead to synchronized transmission of the multiple flows such that a delay between a (e.g., last or latest) PDU in a first flow and a (e.g., last or latest) PDU in a second flow satisfies one or more parameters, such as different expected time of arrival threshold values. In some embodiments, PDUs may be associated with an application data unit (ADU) in the first flow and an ADU in the second flow.

Abstract: Methods and apparatus for burst transmission are provided. A wireless transmit/receive unit (WTRU) is configured to receive configuration information for a periodic search space (P-SS) and a semi-persistent search space (SP-SS). The configuration information may include a monitoring periodicity of the P-SS and a monitoring periodicity of the SP-SS. The P-SS may be associated with the SP-SS. The WTRU is configured to monitor the P-SS with the periodicity of the P-SS. The WTRU is configured to receive a first message in a first physical downlink control channel (PDCCH) in a slot of the P-SS. The first message may indicate an activation of the associated SP-SS. The WTRU is configured to monitor the SP-SS using the periodicity of the SP-SS. The WTRU is configured to receive a second message in a second PDCCH in a slot of the SP-SS.

Abstract: A method and apparatus for providing for full-duplex (FD) operation in time division duplex (TDD) communications are disclosed herein. A wireless transmit/receive unit (WTRU) may receive an indication of a first, UL heavy, TDD uplink (UL)/downlink (DL) configuration and an indication of a second, DL heavy, TDD UL/DL configuration. The WTRU may also receive a grant in a common DL subframe. The WTRU may apply the hybrid automatic repeat request (HARQ) process timing associated with one of the TDD UL/DL configurations for DL HARQ feedback. Also, the WTRU may monitor a set of subframes for a UL or a DL grant. Further, the WTRU may receive a grant in a subframe which may include an indication of a reference TDD UL/DL configuration. The WTRU may then apply the HARQ process timing associated with the reference TDD UL/DL configuration for DL HARQ feedback.

Abstract: Methods, apparatuses, systems, etc., directed to performing positioning of a wireless transmit/receive unit (WTRU) while it is in idle mode and/or inactive mode (collectively “idle/inactive mode”) in NR are disclosed herein. Performing positioning, including positioning measurement and/or reporting, in idle/inactive mode may allow for increased positioning accuracy and/or decreased latency of location determination. In various embodiments, a WTRU in idle/inactive mode may transmit a positioning measurement report in various ways, including (i) in a Random-Access Channel (RACH) preamble; (ii) appended to a RACH preamble; and/or (iii) in a Physical Uplink Shared Channel. In various embodiments, a WTRU in idle/inactive mode may transmit uplink-based positioning related reference signals. In various embodiments, a WTRU in an idle/inactive mode may transmit, over a dedicated physical channel, (e.g., downlink) positioning measurement reports and/or reference signals (RSs) for uplink positioning measurements.
