Abstract: A UE may, responsive to detecting a power-related condition, send a message to induce the master node to release the secondary node. Such a message can include a message reporting a radio link failure of the secondary node, or, if a channel quality indicator is configured for at least some of the secondary cells of the secondary node, reporting a low CQI value so that the network can cease scheduling on such cells. Alternatively, in a carrier aggregation (CA) mode, with the UE connected to a single node comprising a primary cell and one or more secondary cells, the UE may not control which and how many secondary cells with which it communicates. In such a scenario, if such secondary cells are configured for channel quality indicator reporting, the UE may report a low CQI value so that the node will cease scheduling data on such cells.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a synchronization signal block associated with a first channel number as part of a scan, wherein the synchronization signal block indicates a second channel number corresponding to a cell-defining synchronization signal block. The UE may attempt acquisition for the cell-defining synchronization signal block at an elevated priority level based at least in part on the synchronization signal block indicating the second channel number. Numerous other aspects are provided.

Abstract: Systems, methods, and devices of the various aspects may enable a mobile communication device to make a second emergency call attempt in a packet switched (PS) domain in response to determining that a first emergency call attempt in a PS domain failed. The various aspects may enable a second emergency call attempt in a PS domain without requiring the mobile communication device to attempt an emergency call in a circuit switched (CS) domain in response to determining that a first emergency call attempt in a PS domain failed.

Abstract: This disclosure discloses various vehicle-to-everything (V2X) wireless communication processes that use switching diversity to improve coverage over that of a single transmit antenna. Switching diversity may be implemented by alternating the transmit antennas according to a certain switching pattern. A V2X device determines a pattern for alternating a plurality of antennas for transmitting data packets. The V2X device selects, based on the pattern, a first antenna of the plurality of antennas, and transmit a first packet of the data packets using the first antenna. The V2X device further select, based on the pattern, a second antenna of the plurality of antennas, and transmit a second packet of the data packets using the second antenna.

Abstract: Certain aspects of the present disclosure provide techniques for per-flow jumbo maximum transmission unit (MTU) in new radio (NR) systems. A method of wireless communication by a user equipment (UE) is provided. The method generally includes determining a default MTU size to be used for communications in a packet data network (PDN). The method includes determining one or more per-flow MTU sizes, different than the default MTU size, to be used for communications in the PDN. The method includes communicating in the PDN according to the determined per-flow MTU sizes.

Abstract: The disclosure relates to determining priority access with dual access barring classes. An aspect receives, at a client device, at least one high priority access barring class and at least one low priority access barring class, switches to the low priority access barring class, receives an access barring message, and switches to the high priority access barring class in response to receiving the access barring message. An aspect receives a call request for a high priority call among a group of client devices, transmits a notification to a network instructing it to transmit an access barring message in response to receiving the call request, wherein one or more members of the group of client devices switch to a high priority access class in response to receiving the access barring message, and suppresses call announcements for non-priority call requests after transmitting the notification.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure a parameter associated with a secondary cell group. The UE may perform an optimization response action for a dual connectivity mode of a first frequency parameter or a second frequency parameter when the parameter satisfies a threshold, wherein the optimization response action is associated with whether the secondary cell group is operating with the first frequency parameter or the second frequency parameter. Numerous other aspects are described.

Abstract: A method for wireless communication at a user equipment (UE) and related apparatus are provided. In the method, the UE identify, based on a support of a cell for the UE operating with reduced capability, a cell type of the cell. The cell type is one of a reduced capability (RC) type, a fallback (FB) type, or a neither (N) type, corresponding to various support for the UE operating with the reduced capability. The UE further configures a device mode, where the device mode includes an RC mode or a FB-allowed mode, and manages the connection between the UE and the cell based on the device mode and the cell type.

Abstract: Techniques and apparatus for generating a response to a query input into a generative artificial intelligence model. An example method generally includes generating, based on an input query and a first generative artificial intelligence model, a sequence of tokens corresponding to a candidate response to the input query. The sequence of tokens and the input query are output to a second generative artificial intelligence model for verification. One or more first guidance signals for the generated sequence of tokens are received from the second generative artificial intelligence model. The candidate response to the input query is revised based on the generated sequence of tokens and the one or more first guidance signals, and the revised candidate response is output as a response to the received input query.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may disconnect from a first radio access technology (RAT) service, independent of signaling from the first RAT service, after sensing that the UE has entered a coverage hole. The UE may use a connection to a second RAT service while in the coverage hole in association with disconnecting from the first RAT service. The UE may disconnect from the second RAT service, independent of signaling from the second RAT service, after sensing that the UE has exited the coverage hole and before expiration of a radio link failure (RLF) timer for the second RAT service. The UE may reconnect to the first RAT service before expiration of an RLF timer for the first RAT service. Numerous other aspects are described.
