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: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may attempt to establish a data session with a base station. The UE may transmit one or more session request messages including one or more route selection descriptors (RSDs) to the base station, and the UE may determine a successful RSD that may be compatible with the network based on a session accept message received from the base station. The UE may store the successful RSD at a location in memory for use in future session establishment procedures. For example, the UE may go out of service, and may re-acquire service with the same network. In such cases, the UE may transmit a session request message including the previously-accepted RSD to re-establish a data session with the base station.

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: Aspects of the present disclosure provide techniques for improving emergency calls by a user equipment (UE) in certain scenarios. The techniques generally include receiving a trigger for the UE to perform a circuit switched (CS) emergency call via a first subscriber identity module (SIM) that is serving as a default data subscriber (DDS), attempting the CS emergency call via the first SIM, detecting a failure to perform the CS emergency call via the first SIM, and re-attempting the CS emergency call via a second SIM, in response to the detection.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a traffic descriptor that includes a character string corresponding to an application of the UE. In some cases, the character string may be encoded to represent a sequence of characters in the character string to index or match applications to different network slices for communications for the UE. For example, the character string may be encoded using American Standard Code for Information Interchange (ASCII) encoding. After receiving and decoding the encoded traffic descriptor, the UE may identify a matching network slice for the application corresponding to the character string of the traffic descriptor. Subsequently, the UE may attempt to establish a connection with the matching network slice for communications for the application and may communicate with the matching network slice for the application based on a successful establishment of the connection.

Abstract: This disclosure provides systems, methods and apparatuses for a high priority route selection descriptor (RSD) selection timer. A protocol data unit (PDU) session may be established for an application associated with a user equipment (UE). If the PDU session is associated with a lower RSD priority than the highest RSD priority for the application, the UE may initiate an RSD selection timer. After expiration of the RSD selection timer, the UE may try to establish another PDU session for the application with the highest RSD priority for the application. If another PDU session with the highest RSD priority is accepted, the UE may release the initial PDU session with the lower RSD priority and establish a new PDU session with the highest RSD priority. Such implementations may increase data rates, quality of service, and reliability for the application, decrease latency of the application, or decrease power consumption of the UE.

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: Disclosed are techniques for wireless communication. In an aspect, a UE sets up an evolved packet system fallback (EPSFB) call procedure that is associated with network-configured inter-frequency measurements to be performed by the UE at a first inter-frequency measurement interval. The UE punctures some or all of the network-configured inter-frequency measurements during the EPSFB call procedure.

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.
