  • Patent number: 11540111
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first subscriber identity module (SIM) of a user equipment (UE) may detect that the UE is operating in a high mobility environment. The first SIM of the UE may transmit, to a second SIM operating in an idle mode, an indication that the UE is operating in the high mobility environment and an indication of a first frequency error estimation associated with the first SIM. The second SIM of the UE may operate in a high mobility mode using a second frequency error estimation that is based at least in part on the first frequency error estimation associated with the first SIM. Numerous other aspects are described.

  • Patent number: 10681583
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may measure a power value for each beam from one or more cells and calculate an average beam power for each cell. The UE may transmit these calculated averages to a base station in a report, and the base station may select a cell for communications based on the measurement report. The UE may also include a number indicating how many beams are used when calculating an average beam power, a ratio between a maximum and minimum beam power for each cell, two average beam powers based on two defined thresholds, or a combination of these measurements, in the transmitted report. The UE may add a bias to the average beam power for a particular cell to indicate a preference for that cell over the other candidate cells.

    Abstract: Minimizing conflicts between different radio access technologies (RATs) is disclosed herein which include monitoring, by a user equipment (UE), a first use of a UE Radio Frequency (RF) resource by a first Radio Access Technology (RAT). The UE monitors a second use of the UE resource by a second RAT. The UE is served by a current serving cell in the second RAT. The UE may also determine a percentage of conflict between a first use of a UE resource by a first RAT and the second use of the UE resource by the second RAT over a predefined period of time, and initiating, by the UE, a cell reselection attempt to one or more neighboring cells of a plurality of neighboring cells serving the second RAT based on the determined percentage of conflict exceeding a predetermined threshold.

  • Patent number: 9930530
    Abstract: Methods and apparatuses are provided for synchronizing security parameters between access terminals and a wireless network. An access terminal and network entity can conduct a security mode procedure where the access terminal sends a security mode complete message to the network entity. On receipt of the security mode complete message, the network entity may update to new security parameters. The access terminal may initiate a mobility procedure while the security mode procedure is ongoing and may, as a result, abort the security mode procedure and revert back to the old security parameters. The access terminal can send a mobility update message to the network entity including a dedicated status indicator adapted to inform the network entity that the access terminal has reverted back to the old security parameters. In response to the mobility update message, the network entity may revert back to the old security parameters.

  • Publication number: 20180013897
    Abstract: A communication device may be configured to access a plurality of subscriptions for a plurality of providers. For example, a communication device may be configured with at least one subscriber identity module (SIM). For a communication device having a plurality of subscriptions accessible thereto, the selection of a subscription to connect to a destination network may be configurable. The selection of a subscription from a plurality of available subscriptions may be based on a cost (e.g., financial cost, data cost, or another resource) associated with connecting to a destination network using different subscriptions. For example, a first subscription may be selected if connection to the destination network is more expensive using a second subscription and/or if the balance on the second subscription is too low.

  • Publication number: 20170353898
    Abstract: According to various embodiments, there is provided a method for a wireless communication device having at least one Subscriber Identity Module (SIM) associated with a subscription to manage communications over the subscription. The method may include determining a value of a computer processing unit (CPU) load of the wireless communication device, the CPU load based on data operations of the at least one SIM and contributing to a thermal state of the wireless communication device. The method may further include determining whether the value of the CPU load is greater than a load threshold. The method may further include, in response to determining that the value of the CPU load is greater than the load threshold, performing a variable tuneaway at the at least one SIM during which the at least one SIM is configured to halt the data operations, a length of the variable tuneaway based on the value of the CPU load.
