Abstract: A method of wireless communication performed by a user equipment (UE) includes: operating in a Dual SIM Dual Active (DSDA) mode or a Dual SIM Dual Standby (DSDS) mode in which a first subscriber identity module (SIM) is designated as a default data subscription (DDS); determining a recommendation to change the DDS from the first SIM to a second SIM at a modem; informing a user of the recommendation to change the DDS; changing the DDS in response to, at least in part, the recommendation an input from the user; updating a first state variable to indicate a state of the DDS; and routing internet data to the second SIM.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first edge application server (EAS) discovery message from an application client that is external to the UE. The UE may transmit a second EAS discovery message to an edge enabler server (EES) based at least in part on the first EAS discovery message. The UE may receive, from the EES, an EAS response message. The EAS response message may indicate a failure of a discovery request associated with the application client or the EAS response message may indicate an EAS associated with the application client. The UE may transmit an indication of the failure of the discovery request or an indication of the EAS to the application client. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish, in a communication mode, a communication connection with a first radio access technology (RAT) or a second RAT. The UE may receive or identify an indication to deprioritize the first RAT. The UE may perform, based at least in part on the indication to deprioritize the first RAT, an action to deprioritize the first RAT, where the action is based at least in part in the communication mode. Numerous other aspects are described.

Abstract: Methods, systems, and devices are described for concurrently performing handoff-related measurements for neighbor cells using multiple input multiple output (MIMO) antenna resources. In one example, a mobile device is in communication with a serving cell. Handoff-related measurements of first wireless signals from a first neighbor cell are performed. The first wireless signals are received at first MIMO antenna resources of a device. Handoff-related measurements of second wireless signals from a second neighbor cell are performed, as well. The second wireless signals are received at second MIMO antenna resources concurrently with the first wireless signals received at the first MIMO antenna resources. The first handoff-related measurements and the second handoff-related measurements may be performed during a scan interval. A type of handoff-related measurement to perform may be determined based on a determined length of the scan interval.

Abstract: Certain aspects of the present disclosure provide techniques for a domain name system (DNS) override for edge computing. Embodiments include receiving signaling indicating an address of a DNS server. Embodiments include receiving signaling indicating an address of an edge DNS server. Embodiments include intercepting a DNS request from an application. Embodiments include changing a destination address of the DNS request to the address of the edge DNS server. Embodiments include intercepting a DNS response from the edge DNS server that is sent in response to the DNS request. Embodiments include upon determining that the DNS response does not comprise a failure notification, changing a source address of the DNS response to the address of the DNS server.

Abstract: A delta configuration is signaled for handover of a wireless communication device (e.g., a user equipment, UE) from a first form of connectivity to a second form of connectivity. For example, a UE with master cell group (MCG) connectivity may be handed-over to multiple radio access technology-dual connectivity (MR-DC). In some examples, a UE with standalone (SA) connectivity may be handed-over to non-standalone (NSA) connectivity (e.g., dual connectivity). In conjunction with this handover the UE may be signaled as to whether the UE is to reuse a configuration from the first connectivity mode during the second connectivity mode.

Abstract: Certain aspects of the present disclosure provide techniques for selecting policies for routing of data traffic. Certain aspects provide a method for wireless communication by a user-equipment (UE). The method generally includes selecting at least one policy for routing of data traffic to a network, wherein the policy comprise an access network discovery and selection policy (ANDSP) if the UE has the ANDSP provisioned regardless of whether the UE is registered to evolved packet core (EPC) or fifth-generation core network (5GCN), and communicating the data traffic to the network based on the selection.

Abstract: Certain aspects of the present disclosure provide techniques for reporting an indication of a PHR when the UE's assigned of UL resources is insufficient to transmit both UL data and a PHR. Additionally, aspects described herein introduce a negative PHR used to indicate the UE requires additional UL resources.

Abstract: A user equipment (UE) reduces delays associated with inter-radio access technology (IRAT) measurements. In one instance, the UE determines whether a first signal quality of a serving cell, a second signal quality of an intra frequency neighbor cell of a serving RAT (radio access technology), and/or a third signal quality of an inter frequency neighbor cell of the serving RAT is below a first threshold. The UE also determines whether a fourth signal quality of at least one cell of a neighbor RAT is above a second threshold. The UE further allocates one or more measurement gaps for a synchronization channel decoding procedure for the neighbor RAT based at least in part on the determining whether the fourth signal quality is above the second threshold and determining whether the first, second, and/or third signal quality is below the first threshold.

Abstract: In an application such as voice over LTE (VoLTE), a discontinuous reception (DRX) cycle length may be as short as 20 milliseconds (ms). An inter-radio access technology (IRAT) or intra-RAT measurement may be performed during a 6 ms measurement gap with a 40 or 80 ms periodicity. This may greatly increase user equipment (UE) wakeup time duration during a DRX cycle, and thus the UE's power consumption to perform an inter/intra-RAT measurement. The UE can align a beginning of a UE generated inter radio access technology (IRAT) measurement gap with a beginning of a discontinuous reception (DRX) wakeup period. A secondary receive chain of the UE can perform the detection and measurement of a neighbor cell during the aligned measurement gap. This way, the primary receive chain of the UE can carry on communication tasks such as VoLTE call during the DRX wakeup period.
