Abstract: This disclosure relates to performing implicit radio resource control state transitions in a cellular communication system. A wireless device may establish a radio resource control (RRC) connection with a cellular base station. A data inactivity timer length and a target RRC state for implicit RRC transitions may be determined. A data inactivity timer having the determined data inactivity timer length may be initiated. It may be determined that the data inactivity timer has expired. The wireless device may transition to the target RRC state based at least in part on determining that the data inactivity timer has expired.

Abstract: Some embodiments relate to a user equipment device (UE), and associated methods for enabling the UE to estimate motion of the UE based on cell type. In some embodiments, in response to determining that a serving cell of the UE is not a macro cell, a motion estimation algorithm may be disabled for at least a first time period and when the first time period lapses, the motion estimation algorithm may be partially enabled to estimate speed of the UE for at least a second time period. In response to the speed of the UE remaining above a speed threshold for at least the second time period, the motion estimation algorithm may be fully enabled. In response to the speed of the UE not remaining above the speed threshold for at least the second time period, the motion estimation algorithm may be disabled for at least a third time period.

Abstract: Method and apparatus for adaptive data collection operations where a first user equipment (UE) is paired to a second UE. The first UE may receive capability data from the second UE, the capability data comprising cellular capabilities of the second UE. The first UE may further collect service history data for the second UE, where the service history data corresponds to the cellular capabilities indicated by the capability data. The first UE may further transmit the service history data to the second UE.

Abstract: A device, system, and method detect an activity and utilize a mitigation scheme. The method is performed at a device that is configured to establish a network connection to a network, the network including a plurality of areas, each area being defined based on a grouping of a plurality of neighboring cells, the device being associated with one of the areas at a select time. The method includes determining between an activity status and a non-activity status associated with the device. When the activity status is determined, the method includes determining an area update rate indicating a number of changes to the associated area over a period of time. When the area update rate exceeds a predetermined update rate threshold, the method includes selecting a mitigation scheme configured to reduce an amount of power used by the device.

Abstract: This disclosure relates to techniques for performing ranging wireless communication including prioritization. A first wireless device may transmit a request for ranging services to a second wireless device. The first wireless device may transmit an indication of a ranging priority to the second wireless device. The second wireless device may determine a granted ranging priority. The first and second wireless device may perform ranging communication according to the granted ranging priority.

Abstract: A device sets an activity mode for a cellular connection. A method to set the activity mode is performed at a device located with a user that is configured to establish a network connection to a network. The method includes determining a status of the user, the status indicating an activity state or a non-activity state of the user. The method includes, when the status indicates the activity state, activating an activity mode on the device that restricts select types of mobile originating data traffic.
