Abstract: It is recognized herein that capabilities are lacking related to how different users can be authenticated on top of an existing subscription authentication. In some examples, a user-centric authentication layer may be supported on top of an existing subscription authentication, such that different users may use the same user equipment (UE) with customized services, and different users of devices can be identified behind a gateway with a 3GPP subscription (without the devices having a dedicated 3GPP subscription). Further, a user identifier may be linked to a subscription to access 3GPP services via non-3GPP access.

Abstract: An apparatus includes a processor, a memory; and communication circuitry, the apparatus being connected to a communications network via the communication circuitry, the apparatus further including computer-executable instructions stored in the memory which, when executed by the processor, causes the apparatus to identify an apparatus capability that is an indication of an ability of the apparatus to perform beam failure detection (BFD) for a plurality of cells, transmit the apparatus capability to another apparatus, receive from the other apparatus at least one message including a change in network configuration; and substitute a second set of cells for the first set of cells on which the apparatus performs BFD based on the change in network configuration so the apparatus capability is not exceeded by the network configuration.

Abstract: The present application describes a WTRU including a non-transitory memory including instructions stored thereon for re-establishing a remote radio control (RRC) connection with a base station. The apparatus also includes a processor capable of executing instructions of determining, based upon a measurement in an active downlink bandwidth part (DL BWP), to initiate a random access channel (RACH) procedure. The processor also executes instructions of switching to a default uplink bandwidth part (UL BWP). The processor also executes instructions of initiating the RACH procedure. The process further executes instructions of transmitting a RA preamble using one of the RACH resources configured for the default UL BWP. The processor even further executes instructions of receiving a RA response. The processor yet even further executes instructions of switching from the default UL BWP to either an active UL BWP or another active UL BWP after re-establishing the RRC connection.

Abstract: A wireless transmit/receive unit (WTRU) may receive a tracking reference signal comprising resources located in one or more slots. The resources may be located in one or more symbols used for receiving a demodulation reference signal. The one or more symbols in which the resources of the tracking reference signal are located may be within a first five symbols in each of the one or more slots. At least one resource of the received tracking reference signal may be frequency multiplexed with the demodulation reference signal.

Abstract: Methods and apparatuses are described herein for transmission priority, collisions, and sharing in the COT by frame based equipment (FBE). In accordance with one embodiment, a wireless communications device such as an FBE, may conduct two stage channel sensing to avoid collision between other FBEs nodes. The wireless communications device may adjust the energy threshold to reflect a channel access priority. The FBE may conducting continuous and non-continuous second stage channel sensing. The FBE may perform enhanced two stage channel sensing to exploit the remaining portion of the COT. The FBE may store a configuration for the second stage of channel sensing for both the downlink (DL) and uplink (UL).

Abstract: A Sidelink AS group management function is disclosed for a UE to discover group members and organize them into AS layer sub-groups based on the AS layer group context information. A centralized Sidelink AS group management is disclosed that the Sidelink AS Group Manager discovers group members and organizes them into AS layer sub-groups for a UE. A Subgroup formation and configuration procedure is disclosed that SL AS Group Manager organizes the ULG into AS layer sub-groups, configures UE-to-UE relays for each UE in the ULG and sends the AS group management information to the UE. A distributed Sidelink AS group management method is disclosed that each UE discovers its group members and organizes the ULG into AS layer sub-groups. New Layer 2 structures and procedures are disclosed to enhance bearer management for Sidelink groupcast communications.

Abstract: Sub-band (SB) indications and listen-before-talk (LBT) outcomes may be used to adjust communications between devices such as wireless terminals and base stations. For example, a wireless terminal may receive SB indications including SB configurations and/or LBT outcomes of a base station, and other information such as a remapped CORESET. Similarly, a terminal may determine that a physical resource block (PRB) is invalid based at least in part on whether the PRB overlaps with a guard band. The terminal may be arranged to adjust its searches and transmissions based on received SB indications, and to provide the base station with LBT outcomes of the terminal.
