Abstract: Procedures and mechanisms for narrowband multi-channel transmission for wakeup radio (WUR) operation are disclosed. A station (STA) operating in WUR mode may have its a primary connectivity radio (PCR) turned off and its WUR turned and operating according to previously negotiated WUR operating parameters. The STA may monitor, for WUR beacons and frames over a first WUR channel, and determine that the first WUR channel does not support reliable transmission based on no beacons being received within a first duration. The STA may turn off the WUR, and turn on the PCR to send a first short WUR frame including a wakeup reason, and receive a second short WUR frame with a WUR channel assignment. The STA may turn off the PCR, turn on the WUR, and monitor for WUR signals on a second WUR channel according to the WUR channel assignment and the previously negotiated WUR operating parameters.

Abstract: A wireless transmit/receive unit may request, from a core network, authorization for creating one or more personal networks of one or more devices. After being granted authorization, the UE may be enabled to create a personal network and to cause a PDU session for the personal network to be established with the core network. The UE may enable members of the personal network to send data associated with the personal network via the PDU session.

Abstract: Reliability monitoring and indication may be provided for multicast and broadcast services (MBS). A WTRU may receive an MBS configuration for an INACTIVE state (e.g., suspend PTP and maintain PTM for split MRB). MBS configuration and suspend configuration may be associated with different areas (e.g. MBS area versus RAN area). Configurations may indicate reliability indication triggers (e.g., polling, event-based, periodic), a reliability metric configuration, and/or a reliability indication configuration. A WTRU (e.g., in INACTIVE) may receive an MBS transmission (e.g., on MRB(s)), receive an MCCH (e.g., with trigger(s) for reliability indication during MCCH modification period), determine reliability metric(s) associated with MBS TB reception, monitor reliability metric(s) during time interval(s) for MCCH modification period(s), select RA resources (e.g., per mapping between resources and reliability metric value/range), indicate a reliability metric (e.g., transmit reliability indication via selected preamble and RO), and/or monitor RAR format responsive to the reliability indication transmission.

Abstract: A wireless transmit/receive unit (WTRU) may communicate in a non-terrestrial network (NTN) comprising a plurality of satellites. The WTRU may be preconfigured with a plurality of measurement configurations and a corresponding plurality of activation/deactivation criteria associated with the plurality of satellites. The activation/deactivation criteria includes at least activation timing information. The WTRU may activate and deactivate each of the plurality of measurement configurations over time in accordance with the activation/deactivation criteria. The WTRU may perform measurements on cell beams for satellites with active measurement configurations and report results based on the measurements to NTN.

Abstract: Methods and systems are described herein for bandwidth part (BWP) operation in 5G wireless systems. A wireless transmit/receive unit (WTRU) may be configured to receive a physical downlink control channel (PDCCH) transmission on a first BWP associated with a first carrier. The PDCCH transmission may include scheduling information for receiving a physical shared downlink channel (PDSCH) transmission via a second BWP associated with a second carrier. The WTRU may be configured to determine one or more quasi co-located (QCL) parameters for the PDSCH transmission using a lowest transmission configuration indication (TCI) state associated with the second BWP associated with the second carrier based on a scheduling offset of the PDSCH transmission being less than a threshold and on the PDSCH transmission being received via the second BWP. The WTRU may be configured to receive the PDSCH transmission using the determined one or more QCL parameters.

Abstract: 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.

Abstract: A user equipment (UE) may detect that two or more of the slices that were requested by the UE cannot be served by the same access and mobility management function (AMF). Once the UE is able to determine that the multiple requested slices cannot be served by the same AMF, the UE may account for this incompatibility. For example, the UE may decide to only request compatible slices, or the UE may execute procedures with the network that allow the UE to simultaneously communicate with multiple AMFs. By allowing the UE to communicate with multiple AMFs, the UE may be able to utilize separate AMFs to register to slices that cannot be served by the same AMF. The system may allow for the UE to be paged by multiple AMFs.

Abstract: Methods, apparatus and systems are disclosed. One method may be implemented by a first Wireless Transmit/Receive Unit (WTRU) having established an indirect link with a second WTRU. The method may include performing a Discovery procedure and detecting, based on a result of the performed Discovery procedure, that the second WTRU is directly reachable. The method may further include initiating establishment of a direct link, switching from the indirect link to the direct link and communicating, by the first WTRU with the second WTRU, using the established direct link after the switch.

Abstract: A wireless transmit/receive unit (WTRU) may be configured to measure a downlink quality associated with at least one first beam. The WTRU may be configured to determine whether the measured downlink quality associated with the at least one first beam is below a threshold value. The WTRU may be configured to receive at least one control channel transmission using a determined second beam, based on, in part, a determination that the measured downlink quality associated with the at least one first beam is below the threshold value. The determined second beam used to receive the at least one control channel transmission may be a same beam that is used to receive an associated data channel transmission. The determined second beam may be from a set of beams. The set of beams may be received via higher layer signaling.
