Abstract: A receiving user equipment (UE) may be configured perform operations relating to sidelink communications with a transmitting UE. The receiving UE may establish a sidelink session with a transmitting UE, perform a local sensing, receive a Physical Sidelink Control Channel (PSCCH), a Physical Sidelink Shared Channel (PSSCH), and reserved multiple resources from the transmitting UE, whereby the transmitting UE reserves the reserved multiple resources. The receiving UE determines whether a coordination message is triggered and, in response to the coordination message being triggered, the receiving UE transmits the coordination message to the transmitting UE, the coordination message indicating whether a collision occurs among the reserved multiple resources.

Abstract: Systems and methods for performing measurements of one or more cells during an small data transmission (SDT) procedure between a user equipment (UE) and a network when the UE is in a radio resource control (RRC) INACTIVE state are described herein. Beam and/or cell measurements taken during an SDT measurement period of the SDT procedure may be used to determine one or more respective cell qualities, among other possibilities. Beginnings and endings of the SDT measurement period, and the manner (timing) for taking measurements within the SDT measurement period, are also described. The cell qualities so determined can then be used to monitor, during the SDT measurement period, for a measurement event, which causes the UE to send a measurement report to the network having data determined using those cell qualities, and/or to send messaging intended to induce the network to change the RRC state of the UE.

Abstract: Systems and methods for multicast data traffic service continuity under multicast-broadcast services (MBS) operation during a radio resource control (RRC) state or mode transition are described. In some embodiments, a user equipment (UE) receives, from a network, while in an RRC connected mode, an RRC release message comprising an RRC inactive mode point to multipoint (PTM) configuration that uses an MBS session to receive multicast data traffic while the UE is in an RRC inactive mode; enters the RRC inactive mode from the RRC connected mode in response to the RRC release message; and uses the RRC inactive mode PTM configuration to receive, from the network, the multicast data traffic of the MBS session while the UE is in the RRC inactive mode. Cases where a UE instead re-uses an RRC connected mode PTM configuration after transitioning to the RRC inactive mode are also described. Analogous network behaviors are described.

Abstract: A user equipment (UE) may be configured with information to perform conditional handovers or addition/change of a primary secondary cell (PSCell). The UE receives a first radio resource control (RRC) configuration message from the source cell for conditional handover to the at least one target cell, the first RRC configuration message including conditional handover execution conditions, an RRC configuration and a target cell ID for each one of a list of target cells, performs measurements on the target cells to determine whether any one of the target cells fulfills its corresponding conditional handover execution conditions and, when a first target cell from the list of target cells fulfills its corresponding conditional handover execution conditions, initiates a handover to the first target cell.

Abstract: Systems, apparatus and methods enable layer 2 (L2) relaying optimizations for a remote user equipment (UE) to receive system information (SI) from a relay UE. The relay UE may establish a sidelink communication channel with the remote UE that is in a radio resource control (RRC) idle state, an RRC inactive state, or an out-of-coverage (OOC) state with respect to the base station. The relay UE decodes a relay SI request received through the sidelink communication channel from the first remote UE. The relay SI request indicates requested system information. The Relay UE obtains the requested system information or a subset of the requested system information from a memory device or from the base station and encodes a relay SI response to send to the first remote UE. The relay SI response includes the requested system information or the subset of the requested system information.

Abstract: Techniques discussed herein can facilitate improved security establishment procedures for Vehicle to Everything (V2X) direct connections. Various embodiments are employable at or comprise User Equipment, and can initiate and/or receive V2X security establishment connections wherein a receiving UE can reject the connection based on the initiating UE's capabilities/policy and/or the initiating UE can make the final decision regarding the connection based at least on receiving security policy and capability information from the receiving UE.

Abstract: Apparatuses, systems, and methods for PDCCH enhancements for group-based paging indications. A user equipment device may be configured to receive, from a network, an indication of a paging occasion via a PG-RNTI and/or via at least 6 bits of a DCI. A value of the PG-RNTI may be associated with the paging occasion as well as a set of UEs, including the UE. The UE may be configured to monitor the paging occasion based on the value of the PG-RNTI and receive, during the paging occasion, a paging indication via at least six bits of a DCI, where each bit of the at least six bits may indicate a paging indication for a particular set of UEs and the particular set of UEs may be a subset of the set of UEs. The UE may also be configured to, in response to determining that the UE has a paging message, decode a corresponding PDSCH.

Abstract: SL-DRX involves both Uu and PC5 interfaces. For an RRC_CONNECTED UE (also referred to as a connected mode UE, or simply connected UE), several SL-DRX enhancements are described in this disclosure to trigger SL DRX and share configurations. Alignment of SL-DRX alignment with Uu-DRX (referred to as Uu/SL DRX alignment or simply alignment) is also described, as an optional feature (since not all schedules can temporally align).

Abstract: Techniques for flexible hybrid automatic repeat request selection by a user equipment are provided. An example method includes a user equipment (UE) processing a plurality of physical uplink shared channel (PUSCH) opportunities associated with a configured grant (CG) cycle. The UE can apply a first logical channel prioritization (LCP) setting when processing a first PUSCH opportunity of the plurality of PUSCH opportunities. The UE can evaluate whether a condition for switching from the first LCP to a second LCP of the plurality of PUSCH opportunities has been met. The UE can, based on the evaluation, apply a second LCP setting when processing the second PUSCH opportunity.

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.
