Abstract: A user equipment (UE) may operate on a dormant bandwidth part (BWP) and a non-dormant BWP of a carrier. The UE identifies a dormant bandwidth part (BWP) and a non-dormant BWP of a carrier corresponding to a primary secondary cell (PSCell) of a secondary cell group (SCG) for dual connectivity (DC), receives an indication that an active BWP is to be switched from the non-dormant BWP to the dormant BWP and performs an action corresponding to the dormant BWP.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) to transmit an indication of a link failure on a secondary cell. The indication may be transmitted on resources selected based on one or more conditions. One or more priority rules may be used to resolve collisions. The UE may further make an assumption of a beam or beams to use for communications with the secondary cell following the link failure and prior to receiving an indication from the network of a selected beam.

Abstract: A user equipment (UE), next generation NodeB (gNB), or other network component can operate to configure a group configuration message that initiates a plurality of UEs in a coverage area of a non-terrestrial network (NTN) to concurrently transfer communication from a first beam of a first satellite to a second beam of a second satellite. The communications of one or more UEs can be re-directed to the second beam of the second satellite based on downlink control information of the group configuration message.

Abstract: Provided is a method for a user equipment (UE). The UE obtains a cell reselection indication from a network device. The cell reselection indication indicates to the UE whether a terrestrial network (TN) cell or a non-terrestrial network (NTN) cell serves as a camping cell for which the UE performs cell reselection; The UE performs the cell reselection based on the cell reselection indication.

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 LIE 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: A user equipment (UE) device comprising a processor configured to perform operations is described. In an exemplary embodiment, the operations include comprising establishing a sidelink session with a transmitting UE; configuring the sidelink session to support coordinated resource selection prior to performing the local sensing; performing a local sensing; receiving a PSCCH and a PSSCH from the transmitting UE. The transmitting UE reserves multiple resources. The processor is further configured to perform operations including determining whether a collision happens among the multiple reserved resources; and transmitting the coordination message to the transmitting UE.

Abstract: Techniques for physical uplink control channel (PUCCH) operation with multiple transmission and reception point (multi-TRP) are disclosed. In some embodiments, determining PUCCH transmission repetition may include determining that an original PUCCH transmission overlaps a slot boundary between a first slot for PUCCH transmission and a second slot for PUCCH transmission, and configuring a PUCCH repetition of the original PUCCH transmission. The PUCCH repetition may include one or more symbols of the original PUCCH transmission and may be located in one or more slots other than the first slot and the second slot. The PUCCH repetition may be configured by a downlink control information (DCI) configuration that includes a physical downlink shared channel to hybrid automatic repeat request acknowledgement feedback (PDSCH-to-HARQ_feedback) timing indicator, a PUCCH repetition number field that configures a number of transmissions of the PUCCH repetition, or a PUCCH resource indicator field that configures a number of transmissions of the PUCCH repetition.

Abstract: A user equipment (UE) device may perform random access to a base station in the context where propagation delay between the base station and the UE device is large. The UE device randomly selects a random access preamble from an available set of preambles. The UE device selects a time slot for transmission of the random access preamble based on a configured correspondence between allowable time slots and subsets of the available set. The UE device transmits the random access preamble to a base station in the selected time slot, with timing advance to compensate for a common delay. Thus, the base station, knowing the configured correspondence, is able to determine the time slot in which the random access preamble was transmitted. The UE device receives a random access response that has been addressed with a Random Access Radio Network Temporary Identifier (RA-RNTI).
