Abstract: Light and/or Inactive state connectivity and/or autonomous mobility techniques are contemplated. A WTRU may, for example, have an inactive/idle mode, a light connected/loosely connected/Inactive mode and/or a connected/fully connected/Active mode. A WTRU in light connected mode may have a WTRU context stored in a RAN. A WTRU may perform an area monitoring procedure while in light connected state. A WTRU may engage in autonomous mobility during light connectivity. A WTRU may move within a logical area (e.g., a RAN paging area), perhaps without notifying the network. The WTRU may provide notice when it has moved outside a logical area (e.g., update RAN paging area). Mobility in light connected state may be network controlled (e.g., to enable handover when data transfer may be allowed and/or ongoing). A WTRU may be reachable during a light connectivity state. A WTRU may engage in autonomous mobility during light connectivity and/or an Inactive state.

Abstract: A method for use in a wireless transmit/receive unit (WTRU) for initial access using a system signature or signature sequence is described herein. The WTRU may receive a system signature from at least one transmission-reception points (TRP) of a plurality of TRPs. The system signature may be associated with a numerology, a network slice, a discontinuous transmission (DTX) state, a control channel characteristic, and/or a network service. The WTRU may then determine with use of a stored access table a resource selection, an initial access method of a plurality of initial access methods, a network slice, a network service, or a group of the at least one TRP. The WTRU may then receive at least one random access response (RAR) message from the at least one TRP. The WTRU may then associate with the at least on TRP based on the received at least one RAR message.

Abstract: Methods, apparatus, systems, architectures, and interfaces for receiving a Multimedia Broadcast Multicast System (MBMS) service performed by a wireless transmit receive unit (WTRU) are provided. A method may include any of: receiving MBMS service configuration information including information indicating, for an MBMS service, an association between a transmission mode (TM) and a bandwidth part (BWP); receiving the MBMS service using a first BWP according to the received MBMS service configuration information; detecting a trigger for changing use of a BWP from using the first BWP to using a second BWP for receiving the MBMS service; determining a TM associated with the second BWP according to an association between a TM and the second BWP, according to an association indicated by the information included in the MBMS service configuration information; and receiving the specific MBMS service via the second BWP according to the TM associated with the second BWP.

Abstract: Systems, methods, and instrumentalities are disclosed herein for pre-processing for channel state information (CSI) compression in wireless system. A WTRU may receive configuration information that indicates a reference signal and a data processing model for channel state information (CSI) compression. The WTRU may determine CSI associated with a channel using the reference signal. The WTRU may determine a channel condition associated with pre-processing. The WTRU may select a pre-processing type from a plurality of pre-processing types based on the data processing model and the determined channel condition associated with pre-processing. The WTRU may pre-process the CSI associated with the channel based on the selected pre-processing type. The WTRU may generate compressed CSI by compressing the pre-processed CSI using the data processing model for CSI compression. The WTRU may send the compressed CSI to a network.

Abstract: Methods and apparatus for power saving in a wireless network are disclosed. A Wireless Transmit/Receive Unit (WTRU) may comprise a transmitter, a receiver, and a processor. The processor may determine a processing state pertaining to behavior of the WTRU and determine a minimum amount of resources to be processed for one or more sets of physical resources based on the determined processing state. Each respective set of physical resources may comprise resources in time, and any of frequency or space. For each respective set of physical resources, the time may comprise a frame structure associated with a numerology applicable to the respective set of physical resources, the frequency may comprise any of a frequency location, a bandwidth, or the numerology, and the space may comprise one or more beams. The processor may process the determined minimum amount of resources of the one of more sets of physical resources.

Abstract: Embodiments include methods, systems, and apparatuses for receiving a first type of transmission and a second type of transmission. A WTRU may receive a first downlink control information (DCI) during a first downlink (DL) transmission interval allocating first radio resources in the first DL transmission interval for reception of a first type of transmission. The WTRU may receive data from the first type of transmission in the first radio resources. The WTRU may receive data from a second type of transmission in second radio resources that include one or more predetermined regions within the first radio resources. The WTRU may receive a second DCI during a subsequent second DL transmission interval indicating that the data from the first type of transmission was preempted by the data from the second type of transmission. The WTRU may process the data from the first type of transmission based on the second DCI.

Abstract: Systems, methods, and instrumentalities are described herein that may be associated with new radio (NR) vehicular communication (V2X) sidelink power saving for unicast and groupcast. A first wireless transmit/receive unit (WTRU) may receive a message. The message may indicate a set of configuration groups and/or one or more suitability selection parameters. The WTRU may receive, from a second WTRU, a first indication. The first indication may indicate that the second WTRU is associated with a first configuration group and a first priority group. The first WTRU may receive, from a third WTRU, a second indication. The second indication may indicate that the third WTRU is associated with a second configuration group and a second priority value. The first WTRU may select a configuration group from the set of configuration groups based on the first indication and the second indication.

Abstract: A system and methods for performing phased reconfiguration in a wireless communications system are disclosed. A wireless transmit/receive unit (WTRU) may perform a phased reconfiguration from a source cell to a target cell. The WTRU may be connected to the source cell and may execute a first set of functions towards the source cell. The WTRU may monitor for a first set of preconfigured trigger conditions and a second set of preconfigured trigger conditions. The WTRU may commence a second set of functions towards the target cell based on detection of at least one of the first set of preconfigured trigger conditions while continuing to execute the first set of functions towards the source cell. The WTRU may cease to perform at least a subset of the first set of functions towards the source cell based on detection of at least one of the second set of preconfigured trigger conditions.
