Abstract: Provided is a method for a user equipment (UE). The UE generates a first information for the UE for transmission to a network device. The first information is associated with a small data transmission (SDT) procedure in an inactive state of the UE. The UE obtains a first configuration information from the network device. The first configuration information is determined with reference to the first information. The UE determines whether to perform the SDT procedure in the inactive state according to the first configuration information. The UE, in response to determining to perform the SDT procedure in the inactive state, performs the SDT procedure in the inactive state according to the first configuration information.

Abstract: The present application relates to devices and components including apparatus, systems, and methods for partial sensing for resource selection, reevaluation, and preemption. In some embodiments: a UE receives configuration information for a resource pool; determines a type of traffic to be transmitted by the UE, the type to include aperiodic traffic or periodic traffic; determines, based on the configuration information and traffic type, first and second values to define a window for contiguous partial sensing; and performs contiguous partial sensing within the window.

Abstract: Inter-cell mobility may include decoding a first radio resource control (RRC) reconfiguration message received from a first cell. The first RRC reconfiguration message may comprise a first portion of configuration information for performing a cell change to a second cell. A cell change message received from the first cell may be decoded. The cell change message may indicate that a cell change to the second cell is to be performed. A cell change acknowledgment may be encoded for transmission to the second cell. A second RRC reconfiguration message received from the second cell may be decoded. The second RRC reconfiguration message may comprise a second portion of configuration information for performing the cell change to the second cell. The second portion of configuration information may comprise a remaining portion of configuration information to perform the cell change to the second cell.

Abstract: Layer 2 handling during a cell change procedure includes decoding an RRC reconfiguration message received from a first cell. The RRC reconfiguration message includes a Layer 1 (L1) configuration corresponding to a second cell. The first cell and the second cell share an SDAP entity, a PDCP entity, an RLC entity, and a MAC entity. The first cell and the second cell have a separate L1 entity. In response to decoding the RRC reconfiguration message, the L1 configuration corresponding to the second cell is stored. A cell change message received from the first cell is decoded. The cell change message indicates that a cell change from the first cell to the second cell is to be performed. The stored L1 configuration corresponding to the second cell is applied for data transmission and reception associated with the second cell. A cell change to the second cell is initiated.

Abstract: A user equipment (UE) configured to operate in a radio resource control (RRC) connected state with a network cell, receive an RRC message to release or suspend the RRC connected state, the RRC message including an indication for a tracking reference signal (TRS) or channel state information reference signal (CSI-RS) configuration to use during an RRC inactive or idle state, enter the RRC inactive or idle state and apply the TRS or CSI-RS configuration for performing timing and frequency error estimation for decoding downlink control information.

Abstract: An approach is described for a base station to generate a first message and a second message. The base station transmits the first message and the second message to a user equipment (UE). The first message is associated with a cell supported by the base station and includes a first public land mobile network (PLMN) identity index and a first list of one or more network slices supported by a first PLMN associated with the first PLMN identity index. The second message is associated with one or more neighboring cells, and includes the first PLMN identity index and a second list of one or more network slice data associated the first PLMN as supported by the one or more neighboring cells. In addition, at least one of the one or more network slice data in the second list includes a sub-list of one or more neighboring cell data.

Abstract: MBS key distribution includes processing group information associated with an MB session context received from an AF. At least a portion of the group information comprises a TMGI. A plurality of session join requests received from a plurality of UEs are processed. Each of the plurality of session join requests include the TMGI and are associated with the MB session context. A request associated with the MB session context for transmission to an MB-SMF is encoded. A response associated with the MB session context received from the MB-SMF is processed. The response includes a key derived for each of a portion of the plurality of UEs using a UE ID and the TMGI. A DL NAS message and an N2 message are encoded for the plurality of UEs and a base station, respectively. The DL NAS message and the N2 message include the derived key.

Abstract: Systems and methods provide packet data convergence protocol (PDCP) user plane (UP) integrity protection (IP) for a user equipments (UE) and radio access network (RAN) nodes operating in Evolved Universal Terrestrial Radio Access -New Radio dual connectivity (EN-DC). In an attach procedure, a UE may indicate a UE security capability for support of relay node (RN) PDCP UP IP used in LTE. Based on the UE security capability, a master e Node B (MeNB) security capability, and a secondary g Node B (SgNB) security capability, the MeNB may determine whether to use UP IP between the UE and the MeNB, the UE and the SgNB, and/or in a split bearer between the MeNB and the SgNB.
