  • Publication number: 20240080901
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be configured with two subscriber identity modules (SIMs). The UE may select a synchronization beam associated with a random access occasion of a first SIM based on the random access occasion not overlapping in time with a reception opportunity (e.g., a paging occasion) of the second SIM. In some examples, the UE may select the synchronization beam based on an identified signal quality of the synchronization beam (e.g., in comparison to other available synchronization beams that are non-overlapping with the reception opportunity). The UE may perform a random access procedure (e.g., using the first SIM) during the random access occasion associated with the selected synchronization beam and, in some cases, may also monitor (e.g., using the second SIM) resources associated with the paging opportunity.

  • Patent number: 11044783
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that it is a multi-subscriber identity module (SIM) device that supports communications with at least a first subscription corresponding to a first SIM and a second subscription corresponding to a second SIM, where the communications are transmitted or received via a single transceiver of the UE. Accordingly, the UE may simultaneously perform packet-based voice traffic using the first subscription and data communications using the second subscription, where the data communications occur during one or more durations of time in which the packet-based voice traffic is absent. For example, the UE may transmit or receive messages using the first subscription and then transmit or receive messages using the second subscription by tuning the single transceiver away from the communications for the first subscription when the packet-based voice traffic is absent.

  • Patent number: 9959746
    Abstract: In an embodiment, a user equipment (UE) determines an emergency health condition for a user that is defined based on a set of health-related parameters crossing a corresponding set of thresholds. The UE receives health data from a set of health monitoring sensors that are each configured to monitor one or more health-related parameters of the user. The UE detects, while a restricted mode restricting access to a set of communicative functions of the UE is active, that the emergency health condition for the user exists based on the received health data indicating that the set of health-related parameters have crossed the corresponding set of thresholds. The UE disables the restricted mode in response to the detecting. The UE conveys, using one or more communicative functions from the set of communicative functions that are made available by the disabling of the restricted mode, an alarm related to the detected emergency health condition for the user.

  • Publication number: 20170295556
    Abstract: A UE registers with a paging hub to a message forwarding service that is configured to forward information from messages wirelessly transmitted by two or more RANs associated with different RAT-types to the UE over a local wireless network that is separate from the two or more RANs. The UE refrains from monitoring a set of downlink wireless channels used by the two or more RANs while the paging hub monitors the set of downlink wireless channels on behalf of the UE. The paging hub detects a signaling message that is targeted to the UE by a given RAN, and forwards a message including information derived from the signaling message to the local wireless network for transmission to the UE. The UE receives the forwarded message and selectively communicates with the given RAN in response to the received message.
