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: Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for a user equipment (UE) to transmit a configured grant (CG) physical uplink shared channel (PUSCH) including an uplink control information (UCI) without transmitting a physical uplink control channel (PUCCH). The UE determines, based on a configuration received from the base station, a first set of CG PUSCHs. Each CG PUSCH of the first set of CG PUSCHs overlaps with the PUCCH, and is configured to transmit data from the UE to the base station. The UE further determines a second set of CG PUSCHs by excluding a third set of CG PUSCHs from the first set of CG PUSCHs, and select a CG PUSCH from the second set of CG PUSCHs to carry the UCI contained in the PUCCH. The UE further transmits the selected CG PUSCH including the UCI without transmitting the PUCCH.

Abstract: A user equipment (UE) is grouped into a paging subgroup for the purposes of receiving pages from a network. The UE receives, from the network, a paging configuration for a Radio Resource Control (RRC) idle state or an RRC inactive state paging operation, the paging configuration comprising a paging subgroup identification for the UE and monitors paging occasions based on at least the paging subgroup identification.

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.

Abstract: Embodiments described herein include methods, systems, and apparatuses for allowing a user equipment (UE) that supports dynamic spectrum sharing (DSS) with uplink (UL) -shift to access a cell and barring UEs that do not support DSS with UL-shift. Embodiments may use a cell barring field in a master information block and additional filters to indicate a barring state for a network node.
