Abstract: Methods, systems, and devices for wireless communications are disclosed by the present application. A request to establish a call using a first connection may be received, the first connection using a first radio access technology to communicate with a radio access network. During execution of a procedure to establish the call, a command to handover communications from the first connection to a second connection that uses a second radio access technology to communicate with the radio access network may be received. The second connection may be established in response to the command, and a message indicating that the request to establish the call was successfully received may be transmitted over the second connection. Also, a message indicating that an alert of the call is being issued may be transmitted over the second connection.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a first subscription of the UE and a second subscription of the UE are associated with a same cell and are being used for a same radio access technology (RAT). The UE may activate a proxy subscription mode for the first subscription based at least in part on the determination that the first subscription of the UE and the second subscription of the UE are associated with the same cell and are being used for the same RAT, wherein the proxy subscription mode enables the UE to use the first subscription to perform one or more idle mode operations for the second subscription while the second subscription is in an idle mode. Numerous other aspects are provided.

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.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receiving, from abase station, control signaling scheduling transmission of a downlink message within a wireless channel resource. The UE may select a first antenna subset of a plurality of antennas of the UE to receive the downlink message. The UE may identify that a second antenna subset of antennas of the plurality of antennas of the UE is currently available to use for receiving the downlink message based at least in part on detecting a speed environment in which the UE is operating. The UE may monitor, for downlink reception of the downlink message, the wireless channel resource using the first antenna subset and one or more antennas of the second antenna subset.

Abstract: Methods and systems for performing time synchronization for a Cellular Vehicle-to-Everything (C-V2X) wireless interface of a vehicle are provided. In one example, a method comprises: determining, by a vehicle UE, whether a Global Navigation Satellite System (GNSS) receiver of the vehicle receives a GNSS signal including time information for a time synchronization operation for the vehicle's local clock source; based on whether the GNSS receiver receives a GNSS signal including the time information, adjusting a local clock time of the vehicle's local clock source based on one of: the time information included in the GNSS signal, or one or more wireless signals broadcasted from a base station; and adjusting, based on the adjusted local clock time, at least one of: a phase or a frequency of a clock signal supplied to the C-V2X wireless interface.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may receive a first connected mode discontinuous reception (CDRX) configuration from a first cell associated with a first radio access technology (RAT), the first CDRX configuration includes a first indication of a first on occasion. The UE may receive a second CDRX configuration from a second cell associated with a second RAT, the second CDRX configuration includes a second indication of a second on occasion. The UE may determine that the first on occasion and the second on occasion are separated by a threshold. The UE may transmit, based at least in part on the determination that the first on occasion and the second on occasion are separated by the threshold, a CDRX reconfiguration request message.
