摘要： Systems, methods, and instrumentalities are described herein for performing propagation delay compensation. For example, a Wireless Transmit/Receive Unit (WTRU) may be configured with the resources and signals to perform a Propagation Delay (RD) procedure, or a Propagation Delay Information Exchange (PDIE), or a Propagation Delay Compensation (PDC). The WTRU may receive configuration that may identify a reference signal (RS) pair for a path. The WTRU may determine that a trigger condition is satisfied for a path. The trigger condition being satisfied may trigger the WTRU to perform a PDIE. The WTRU may determine a propagation delay (RD) for a path. If the determined RD meets a threshold for the path, the WTRU may apply a PDC to an uplink (UL) transmission that uses the path.

摘要： Systems, methods, and instrumentalities are described herein for enhanced channel access. Resources may be configured to enable load-based equipment (LBE) access in an otherwise frame-based equipment (FBE) network. LBE access may be, for example, LBT category four (Cat 4). A wireless transmit/receive unit (WTRU) may determine whether an LBE resource is valid based on current channel occupancy. A WTRU may use an LBE resource as a function of a transmission priority (e.g., priority of the content of the transmission, for example a first PUSCH transmission may be associated with a first priority and a second PUSCH transmission may be associated with a second priority), transmission type (e.g., whether the transmission is for PUSCH or PUCCH, for DG-PUSCH or CG-PUSCH, for data or CSI or HARQ-ACK, etc.), requirement(s), and/or grant. A WTRU may use an LBE resource, for example, as a fallback resource.

摘要： A WTRU may be configured to perform radio link monitoring (RLM) based on RLM reference signals (RLM-RSs) transmitted in a cell operating in an unlicensed spectrum. The WTRU may evaluate a radio link failure (RLF) status for the cell using a first RLM criteria based on the RLM-RSs. A transmission instance of the RLM-RSs may be skipped, for example, due to a listen before talk (LBT) failure at a gNodeB (gNB). The WTRU may adapt or change the first RLM criteria and/or evaluate the RLF status of the cell operating in the unlicensed spectrum using a second RLM criteria based on determining that the transmission instance of the RLM-RSs was skipped. The first RLM criteria may correspond to a first RLM process that utilizes a first set of RLM parameters. The second RLM criteria may correspond to a second RLM process that utilizes a second set of RLM parameters.

摘要： Systems, methods, and instrumentalities are for identifying, determining, or selecting one or more numerologies in a wireless system. The numerologies may include one or more of a subcarrier spacing, a transmission duration, a symbol duration, a number of symbols, or a cyclic prefix (CP) size. The WTRU may send an access request indicating the identified, determined, or selected one or more numerologies. The access request may be a random access channel (RACH) request or a scheduling request (SR). The WTRU may monitor one or more search spaces for one or more physical control channels. The search spaces may be monitored based on an identified, determined, or selected one or more numerologies. Within one of the search spaces, the WTRU may receive and successfully decode a physical control channel. The WTRU may transmit data based on the numerology associated with the search space in which the physical channel was successfully decoded.

摘要： Methods and devices for offloading and/or aggregation of resources to coordinate uplink transmissions when interacting with different schedulers are disclosed herein. A method in a WTRU incudes functionality for coordinating with a different scheduler for each eNB associated with the WTRU's configuration. Disclosed methods include autonomous WTRU grand selection and power scaling, and dynamic prioritization of transmission and power scaling priority.

摘要： Embodiments contemplate wireless transmit/receive unit (WTRU) transmissions of different types of uplink channels and/or signals in a system deployment where multiple destination points may exist. Some embodiments contemplate that a WTRU may select the destination point of a transmission on a dynamic basis. In one or more systems where destination point selection from among multiple potential destination points may be possible for a WTRU transmission, some embodiments contemplate the determination of the handling of hybrid automatic repeat request (HARQ) retransmissions and for different power headroom reporting mechanisms. Embodiments also contemplate the reduction and/or inhibition of WTRU transmissions to destination points to which the WTRU may have lost connectivity.

摘要： Methods and apparatuses are described herein for spectrum sharing and transmission mechanisms for different channel access priorities. For example, a wireless transmit/receive unit (WTRU) may be configured as either a high priority (HP) WTRU or a low priority (LP) WTRU, wherein a HP WTRU is configured to use a first channel access method for accessing the set of network resources and a LP WTRU is configured to use a second channel access method for accessing the same set of network resources, the second channel access method having a lower priority than the first channel access method. A set of protected network resources may be scheduled within the set of network resources for being accessed by the LP unit (e.g., over a limited period of time) with fewer channel access restrictions (e.g., with a higher priority channel access method than in any unprotected network resources).

摘要： A wireless transmit/receive unit (WTRU) may receive one or more physical downlink shared channel (PDSCH) transmissions and each PDSCH transmission may be associated with downlink control information (DCI) and a group of PDSCH transmissions. Further, the WTRU may determine a first group or a second group based on an indication received in DCI associated with at least one of the PDSCH transmissions. Then, the WTRU may generate hybrid automatic repeat request (HARQ)-acknowledgment (ACK) feedback for data received in one or more PDSCH transmissions associated with the determined group. Moreover, the WTRU may transmit the HARQ-ACK feedback. In an example, the DCI which includes the indication may schedule a plurality of PDSCH transmissions included in the determined group. In another example, the DCI which includes the indication may further include a first codepoint mapped to the first group or a second codepoint mapped to the second group.

摘要： A wireless transmit/receive unit (WTRU) may receive first measurement indication information indicating an activation of measurement reporting. The WTRU may determine a first set of resource elements (REs) based on the first measurement indication information. Further, the first set of REs may be associated with measurement-related time and frequency resources. Also, the WTRU may receive one or more measurement-related signals in the indicated first set of REs. Additionally, the WTRU may perform a measurement of each measurement-related signal. The WTRU may transmit, based on the first measurement indication information, a measurement report based on the measurement of each measurement-related signal. Further, the WTRU may receive second measurement indication information indicating a deactivation of measurement reporting. Also, the WTRU may receive indication information regarding a plurality of sets of REs via radio resource control (RRC) signaling, including at least the first set of REs and a second set of REs.
