Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and/or a master node may use configurations to resume communications with one or more cells of a dual connectivity (DC) or carrier aggregation (CA) scheme. In some cases, the configuration may be used for a secondary cell group (SCG) of the DC scheme. This configuration may include the UE applying a previously stored configuration for the SCG (e.g., including higher-layer and lower-layer configurations of a last serving SN of the DC scheme) if it determines the previously stored configuration is valid. Additionally or alternatively, the configuration may include the network using a previous SCG configuration or reconfiguring the SCG and transmitting this indication in a resume communications message to the UE. In some cases, the network may determine this configuration based on assistance information or reports generated from the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive, from a time-sensitive networking (TSN) application function (AF), a first request for a parameter at a device-side TSN translator (DS-TT) associated with the wireless communication device. The wireless communication device may generate a cause code that indicates that the parameter is supported but not available, if the parameter is not available. The wireless communication device may transmit the cause code to the TSN-AF. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may select at least one target node for a radio resource control connection, wherein the user equipment is in a particular radio resource control communication state when the at least one target node is selected, and wherein the user equipment is configured to communicate using dual-connectivity, wherein context information associated with the user equipment is stored by the user equipment, a master node associated with the user equipment, and a secondary node associated with the user equipment based at least in part on the user equipment being in the particular radio resource control communication state; and/or transmit information to the at least one target node or the master node to cause the context information to be provided to the at least one target node. Numerous other aspects are provided.

Abstract: Methods (1500, 1600, 1700, 1800, 1900), systems (1000, 1400) and devices (705, 805, 1005, 1105, 1205, 1405) for wireless communications are presented. A method (1500, 1600) may include the following operations. A UE determines to perform a handover from a first source device in a first network to a first target device in the first network and from a second source device in a second network to a second target device in the second network (1505, 1605). The UE identifies a time interval for performing a first random access procedure with the first target device in the first network (1510, 1610). The UE initiates a first random access procedure with the first target device (1515, 1615). The UE performs a second random access procedure successfully with the second target device in the second network during the time interval (1520, 1620). The UE transmits or receives from the target device in the second network before the UE finishes performing the first random access procedure with the first target device in the first network (1525, 1630).

Abstract: This disclosure provides systems, methods, apparatus, and computer programs encoded on a computer storage media for providing user equipment mobility history information to a remote computing platform. In one aspect, a user equipment may store user equipment mobility history information in memory within the user equipment. The user equipment may determine whether a radio access network connection state has changed from a primary cell in a radio resource controller state to another cell outside a radio access network, to an inter-radio access technology cell, or to an out of service. The user equipment may transmit the user equipment mobility history information to the remote computing platform in response to determining that the user equipment radio access network connection state has changed from a primary cell in a radio resource controller state to another cell outside a radio access network, an inter-radio access technology cell, or an out of service state.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive information related to a dedicated preconfigured uplink resource (DPUR) in a message releasing the UE to an idle mode or an inactive mode. For example, in some aspects, the information related to the DPUR may identify one or more uplink resources that are allocated to the UE to enable the UE to initiate an uplink data transmission in the idle mode or the inactive mode. The UE may transmit, based at least in part on the information related to the DPUR, uplink data while in the idle mode or the inactive mode. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently performing measurements and other functions in preparation for communicating with a base station on a secondary cell (SCell). In particular, a user equipment (UE) may switch to a certain bandwidth part (BWP) (e.g., a dormant BWP) on an SCell when the SCell is deactivated, and the UE may perform the appropriate measurements and functions on this BWP (e.g., based on reference signals received on this BWP). In some cases, the UE may determine to switch to the BWP for performing the appropriate measurements and functions based on an inactivity timer expiring or based on an indication from a base station (e.g., on a primary cell (PCell)). Accordingly, once the UE activates the SCell for communications with a base station, the latency associated with preparing for communicating on the SCell may be reduced.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a set of cell quality measurements for a set of candidate target cells. The UE may select a target cell, from the set of candidate target cells, and a beam, of one or more beams of the target cell, for a conditional handover procedure and based at least in part on the set of cell quality measurements. The UE may perform the conditional handover procedure to transfer from a source cell to the target cell based at least in part on selecting the target cell and the beam. Numerous other aspects are provided.

Abstract: A wireless device may receive a first synchronization signal block (SSB) in a radio frequency band of a first cell of a neighbor base station, and report a physical cell identifier (PCI) for the first cell to a serving base station. The serving base station may identify, based on the PCI report, whether a radio frequency band of the first SSB is in or off a synchronization raster, and determine whether to instruct the UE to report a global cell identifier (CGI) for the neighbor base station (e.g., CGI for the neighbor cell) based on the identification. The wireless device may identify CGI based system information obtained from the neighbor cell, system information obtained from a master cell associated with the neighbor base station, system information obtained from CGI broadcast from the neighbor cell, or system information requested from the neighbor cell using dedicated resources, based on the instruction.

Abstract: Certain aspects of the present disclosure generally relate to methods and apparatus for performing minimization of drive test (MDT) operations. For example, certain aspects provide a method for wireless communication. The method generally includes receiving, at a radio access network (RAN), a measurement configuration to start a trace of a user-equipment (UE), determining a transition of the UE to an inactive state, and sending one or more messages to coordinate the trace of the UE or indicate that the trace has failed in response to the determination
