Abstract: Disclosed are systems and techniques for wireless communications. For instance, a wireless device may receive a signal from a first wireless network while the wireless device is in an idle mode; determine, from the received signal, a signal to noise ratio (SNR) and a doppler shift; retrieve stored network capability information; and estimate, based on the SNR, the doppler shift, and the stored network capability information, a throughput of the first wireless network.

Abstract: Apparatus, methods, and computer program products for determining a preferred data subscription for data service are provided. An example method may include establishing a connection with a network based on a first subscriber identity and a second subscriber identity. The example method may further include communicating with the network based on the first subscriber identity based on the first subscriber identity being a preferred data subscription. The example method may further include determining to recommend to switch the preferred data subscription to the second subscriber identity based on a utility function based on one or more performance factors and one or more non-performance factors. The example method may further include using the second subscriber identity as the preferred data subscription for data service associated with the UE.

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 and 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 method may include simulating a degradation of at least one of a first wireless communication link with a network or a different second wireless communication link with the network based on detecting that a first set of one or more packets, which were received via the first wireless communication link with the network and were added to a packet buffer, and a second set of one or more packets, which were received via the different second wireless communication link with the network and were added to the packet buffer, satisfy a threshold occupancy of the packet buffer. 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 configure a first channel associated with a first subscriber identity module (SIM), the first SIM associated with data traffic. The UE may configure a second channel associated with a second SIM in a dual SIM dual active (DSDA) mode. The UE may detect, on the second channel, a subscription related data stream that includes voice call traffic. The UE may determine, based on detecting the subscription related data stream, to switch the data traffic from the first SIM to the second SIM based at least in part on a UE operation mode. The UE may switch the data traffic from the first SIM to the second SIM based at least in part on the determination to switch the data traffic. Numerous other aspects are described.
