Abstract: Apparatus, methods, and computer-readable media for adjusting transmit power headroom for a secondary link while operating in an NSA mode are disclosed herein. An example method for wireless communication at a UE includes receiving a request to enter a multi-connectivity mode in which the UE is able to transmit data to a first base station via a first access link or to a second base station via a second access link. The example method also includes determining a first maximum uplink transmit power for transmissions using the first access link. Additionally, the example method includes determining a second maximum uplink transmit power for transmissions using the first access link based on uplink transmissions transmitted during an evaluation window. The example method also includes transmitting, via the first access link, at least one uplink transmission based on the second maximum uplink transmit power.

Abstract: Aspects of the present disclosure provide a method for wireless communications by a user equipment (UE). The method generally includes receiving a request for a wireless connection from an application associated with one or more user equipment (UE) route selection policy (URSP) rules, attempting to establish the wireless connection for the application via a first subscriber identity module (SIM) according to one or more of the URSP rules associated with the application that are supported by the first SIM, and taking one or more actions to establish the wireless connection for the application via a second SIM if the attempt to establish the wireless connection for the application via the first SIM fails.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a signal - to-noise ratio (SNR) of one or more communications from a serving cell satisfies an SNR threshold after establishing a New Radio radio resource control (RRC) connection with the serving cell. The UE may transmit a measurement message to the cell based at least in part, on the determining that the SNR of the one or more communications from the serving cell satisfies the SNR threshold. The UE may receive, from the serving cell, a list of one or more neighbor cells based at least in part on the transmitting the measurement message, and establish an RRC connection to a neighbor cell on the list based at least in part on determining that a radio link failure occurred. Numerous other aspects are provided.

Abstract: Embodiments include systems and methods for enabling fast recovery by a user equipment (UE) from packet switched (PS) call failure in a fifth generation (5G) non-standalone (NSA) network. Various embodiments for recovering from PS call failure in a 5G NSA network may include determining whether a total number of Evolved Packet System (EPS) bearer deactivation requests received from a base station of a 5G NSA network during a time period exceeds a maximum counter value, and disabling 5G data calls on the UE in response to determining that the total number of EPS bearer deactivation requests received from the base station of the 5G NSA network during the time period exceeds the maximum counter value.

Abstract: In an aspect, a UE may determine an initial transmission power for transmission of a physical random access channel (PRACH) preamble of a PRACH procedure based upon a final PRACH preamble transmission power associated with a set of historical completed PRACH procedures. The UE may further attempt an initial transmission of the PRACH preamble based on the determined initial transmission power.

Abstract: Techniques to recover from authentication failure are disclosed. During authentication of a user equipment (UE) with a public land mobile network (PLMN), the UE may receive an AUTHENTICATION REJECT with an extensible authentication protocol (EAP)-failure message. When this occurs, instead of invalidating the universal subscriber identity module (USIM) of the UE, the UE can search for other PLMNs that can potentially pass the authentication challenge. If one is found, the UE can register with the found PLMN.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a subscriber identity module (SIM) dual standby (DSDS) user equipment (UE) may transition a packet data session from a first radio access technology (RAT) associated with a first subscription to a second RAT associated with a second subscription, and may further transmit, over the first RAT responsive to the packet data session transition to the second RAT, one or more messages to tear down the packet data session over the first RAT.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that it is operating in a dual-subscription mode that includes a first subscription and a second subscription. In some cases, the UE may include an application that is requesting to establish a data connection in accordance with an access preference rule for the application. The UE may determine that the access preference rule lacks a match among policies of a first route selection policy associated with the first subscription (e.g., a default subscription). The UE may then evaluate a second route selection policy associated with the second subscription for a policy that matches the access preference rule based on determining the lack of the match among policies of the first route selection policy. The UE may establish the data connection after evaluating the second route selection policy for the matching policy.

Abstract: A method and apparatus improve Voice over Internet Protocol (VOIP) call setup success rate and latency. The method provides for attempting a mobile originated packet switched call, by a user equipment (UE), across a packet switched network with a transmission control protocol (TCP) connection of the Internet Protocol multimedia subsystem (IMS) session. A silent redial of the mobile originated packet switched call is performed in response to a failure of the mobile originated packet switched call, via a circuit switched network. A keep alive message is transmitted over the packet switched network after the circuit switched network call, which allows reconnection to the packet switched network.
