Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may initiate one of a conditional handover (CHO) procedure or a conditional primary secondary cell addition/change (CPAC) procedure. The UE may perform a response action with regard to a configuration of the other of the CHO procedure or the CPAC procedure based at least in part on initiating the one of the CHO procedure or the CPAC procedure. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may receive one or more service data units (SDUs) at a layer two (L2) layer of the transmitting device. The transmitting device may encode, at the L2 layer, the one or more SDUs according to one or more network coding parameters to obtain at least one encoded protocol data unit (PDU), the one or more network coding parameters comprising a rateless code. The transmitting device may generate, for the at least one encoded PDU, at least one corresponding PDU header. The transmitting device may output the at least one encoded PDU and the at least one corresponding PDU header from the L2 layer to a lower layer of the transmitting device for transmission to one or more receiving devices.

Abstract: Methods, systems, and devices for wireless communications are described, in which a base station may determine a load balancing adjustment for traffic communicated through the base station. The load balancing adjustment may be provided at a beam level for one or more beams of a plurality of beams, at a network slice level for one or more network slice IDs of a number of network slice IDs, or combinations thereof. The base station may use the load balancing adjustment to identify one or more updated parameters for triggering a handover of at least one user equipment (UE) between beams or slice IDs of a same cell or different cells. The base station may format a mobility change request that indicates the one or more parameters that are updated, and transmit the mobility change request to another base station to establish parameters for handovers between the base stations.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently collecting and reporting minimization of drive test (MDT) measurements for one or more radio access technology (RAT) types and/or for multiple base stations in a dual connectivity deployment. In one example, a user equipment (UE) may receive an MDT measurement configuration indicating a first RAT type for collecting measurements and a second RAT type for reporting measurements. In this example, the UE may use the measurement configuration to collect MDT measurements for the first RAT type, and the UE may report the MDT measurements to a base station associated with the second RAT. Further techniques for efficiently collecting and reporting MDT measurements in a dual connectivity deployment are also described herein.

Abstract: A client device includes a memory comprising a buffer for buffering data having real-time constraints and a hardware-based processor comprising digital logic circuitry. The processor is configured to execute a real-time application configured to determine times during which the data will be available for download, determine a time at which the data is needed to prevent a buffer underrun for the buffer, and when the data is available, send a request for the data and deadline information representative of the time at which the data is needed to avoid the buffer underrun. In this manner, a sending device can prioritize delivery of the requested data to prevent the buffer underrun for the client device.

Abstract: Methods, systems, and devices for wireless communications are described. An access and mobility management function (AMF) associated with a first radio access network (RAN) may identify a user equipment (UE) connected to a source base station of the first RAN. The AMF may receive a handover message including a voice call continuity handover trigger message indicating a handover of the UE to a target base station associated with a second RAN. In some examples, the AMF may transmit a bypass handover message to a second network device based a on the received handover message. In some cases, the bypass handover message may include the voice call continuity handover trigger message. In some examples, the second network device is a mobility management entity (MME) associated with an Evolved Universal Terrestrial Radio Access Network (E-UTRAN).

Abstract: Aspects relate to wireless communication where a master node (MN) or a secondary node (SN) may initiate a conditional addition of a primary secondary cell (PSCell) or a conditional change from one PSCell to another PSCell. Each candidate target PSCell may provide information to be used by the MN to generate a conditional PSCell addition (CPA) configuration or a conditional PSCell change (CPC) configuration that is sent to a user equipment (UE). This information may indicate an execution condition for each candidate target PSCell and/or radio bearers that each candidate target PSCell supports or does not support. An MN may modify a master cell group (MCG) configuration for a PSCell based on information received from a target SN with an secondary cell group (SCG) configuration for the PSCell. The MN may transmit a CPA or CPC configuration including the modified MCG configuration and the SCG configuration to the UE.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a wireless communications system may support machine learning and may configure a user equipment (UE) for machine learning. The UE may transmit, to a base station, a request message that includes an indication of a machine learning model or a neural network function based at least in part on a trigger event. In response to the request message, the base station may transmit a machine learning model, a set of parameters corresponding to the machine learning model, or a configuration corresponding to a neural network function and may transmit an activation message to the UE to implement the machine learning model and the neural network function.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may transmit assistance information indicating a type of in-device coexistence (IDC) interference at the UE, and indicating a set of associated interference parameters that correspond to an interference pattern of the IDC interference in a time domain, a frequency domain, or both. The set of interference parameters and the interference pattern may describe a pattern of the IDC interference in the time domain, the frequency domain, or both. The UE may receive a message indicating one or more operating parameters associated with a time period that is based on the interference pattern. The operating parameters may be based on the type of IDC, the set of interference parameters, and the interference pattern, and may enable the UE to communicate with a network entity to maintain signaling throughput while decreasing effects of the IDC interference.
