  • Publication number: 20200128415
    Abstract: A device wirelessly communicating over a wireless network may adjust a threshold from a network-configured value to a new value in response to a performance characteristic of an application executing on the device not meeting a specified metric, for example in response to the application experiencing a latency greater than a specified latency value. The threshold may be associated with a measurement event configured by the wireless network, and the device may use the new value for the threshold when performing measurements on wireless channel conditions of the wireless network. When adjusting the threshold, the device may adjust the threshold once per application session of the application, and/or once per current radio resource control (RRC) connection before the wireless network releases the current RRC connection. Furthermore, the device may adjust the threshold only if the network-configured value associated with the measurement event is greater than a specified threshold value.

  • Publication number: 20200128484
    Abstract: Methods related to an inactive state of a user equipment (UE). In one example, when an amount of data in an uplink buffer is less than a threshold, the data is sent to the network while remaining in the inactive state. In another example, when reselecting to a different cell, the UE attempts to reselect to the different cell and remain in the inactive state. When transitioning to a connected state at the reselected cell, the UE sends a resume request including an identification of the first cell. In another example, when a high priority or a background PLMN search is performed in the inactive state, the results are cached and implemented the earlier of when a timer expires or the UE enters an idle state. In another example, a cell reselection criteria is altered in the inactive state to make it less likely that a cell reselection will occur.

  • Patent number: 10588130
    Abstract: Capability exchange enhancements include filtering and/or indexing. In some aspects, a user equipment (UE) determines UE capabilities to be reported to a network based on one or more of: one or more enquiries from the network, received system information, a home operator policy, configuration associated with public land mobile network (PLMN) information of one or more networks, a user preference, or a service type. In other aspects, a UE may report a subset of UE capabilities for features used for the connection establishment. Following connection establishment, the UE may use an identifier to communicate a more complete set of modes of operation that the UE is currently capable of performing. Base stations of the network may share the reported subset so that the UE may avoid transmitting the subset to a target base station.

  • Publication number: 20200077225
    Abstract: Techniques are provided to initiate signal transmissions for possible opportunistic reception by a mobile device, and/or to initiate opportunistic reception of signal transmissions for use in mobile device position location estimation. For example, a mobile device may use assistance data to identify a first signal to be transmitted over a first frequency band and a second signal to be transmitted over a second frequency band during a specific period of time. At least a portion of the second frequency band may be outside of the first frequency band. The mobile device subsequently attempts to opportunistically receive at least the first signal and the second signal via a receiver tuned to a reception frequency band that encompasses at least the first frequency band and the second frequency band. The mobile device may then process the opportunistically received signals to obtain measurements corresponding to at least the first and second signals.
