Abstract: A wireless device, such as user equipment (UE) or other apparatus, like may use a transparent mode operation in which the device is not aware of the operation mode of a base station, such as a gNB or other transmission and receive point (TRP), via the use of configurations for Frame Based Equipment (FBE) and Load Based Equipment (LBE) operating modes. A base station may initiate a Channel Occupancy Time (COT) that is an FBE COT or an LBE COT, in which the wireless device follows FBE or LBE procedures accordingly. A variety of criteria may be applied in determining whether to use FBE or LBE procedures, and to switch between them. A network may use indicate the intention to switch operation mode and may do so via implicit or explicit indications. Similarly, a wireless device may autonomously switch operation mode, and may indicate the selected mode to the network.

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: 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 an other 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: Beam failure recovery may be improved via the use enhanced signaling, counters, and windowing. Signaling may include a beam failure reference signal (BFRS) detection signal, which indicates that an access point (e.g., gNB) has acquired a channel for downlink transmission. Based on the BFRS detection signal, a wireless terminal (e.g., UE) may then monitor a gNB downlink transmission during a maximum channel occupancy time (MCOT). The UE may count missed beam failure reference signal instances and report the count, e.g., via higher layer signaling. Signaling may include a BFRS absence indication reflecting an instance of a BFRS that is not transmitted due to channel unavailability. The UE may then exclude the instance of the BFRS from the count. Signaling may include a gNB response detection signal, which may inform the UE to monitor a gNB downlink transmission. The UE may trigger timer after receiving an access gNB response detection signal.

Abstract: The present application is directed to an apparatus including a non-transitory memory including instructions stored thereon for monitoring synchronous signals and physical broadcast channels (SSBs) from a network node. The apparatus also includes a processor, operably coupled to the non-transitory memory, configured to execute a set of instructions. The instructions include configuring the apparatus for a STTC (SSB Transmission Timing Configuration). The instructions also include monitoring the STTC for the SSBs. The instructions further include determining a first one of the SSBs in a first slot of a subframe in a scheduled SSB transmission in the STTC has been transmitted at a first scheduled location, where the transmission of the first one of the SSBs is based upon confirmation of a successful Listen Before Talk (LBT) available channel prior to the scheduled SSB transmission in the STTC. The instructions even further include determining a second one of the SSBs in the scheduled SSB transmission in the STTC successfully or failed to transmit at a second scheduled location. The instructions yet even further include observing transmission of the second one of the SSBs in the first slot or a second slot.

Abstract: A network entity, such as a user equipment (UE), may request that a network provide multicast and broadcast services, e.g., where the request includes entity preferences such as network slice selection information. The network may provide information regarding provision of such services, where the information may include, for example, whether a service will be provided via a user plane or a control plane connection, network slice information, additional connections to be formed, separate encryption for such connections, etc. A Multicast/Broadcast Network Function (MBNF) may be used to establish such connections and manage a broadcast and multicast sessions. The MBNF may, for example, manage groups of entities, check an entity's access privileges for services, communicate with the a Management and Network Orchestration (MANO) system to reserve resources, and send data to entities over a shared control plane connection.

Abstract: Downlink Control Information (DCI) may be expanded, or enhanced, to allow nodes such as UEs, eNBs, NR-nodes, gNBs, and TRPs in M2M, IoT, WoT networks to coordinate activities on PHY, MAC, and RRC layers. For example, DCI fields may be added or enhanced to include, for example, information regarding time resource allocation, frequency resource allocation, mini-slot allocation, and or Code Block Group (CBG) transmission. Such information, or similar information, may be used in operations such as mini-slot operations, Code Block Group (CBG) transmission, group common Physical Downlink Control Channel (PDCCH), grant-free and grant-less operations, response to Beam Failure Recovery Request (BFRR), UL Transmit (TX) beam change, Quasi-Co- Location (QCL) operations, aperiodic CSI-RS transmission and interference measurement, Band Width Part (BWP) operations, and Multi-Transmission and Reception Point (TRP)/Multi -Panel.
