Abstract: A device, system, and method estimate a link budget on a companion device. The method is performed at a first device connecting to a second device over a first connection and a network over a second connection, the second device connecting to the network over a third connection. The method includes receiving initiating data from the second device based on radio conditions associated with the third connection. The method includes, when the first device disconnects from the second device and establishes the second connection, determining an initial network metric value based on the initiating data that is used to estimate radio conditions associated with the second connection. The method includes selecting a data exchange mode of the first device based on the initial network metric value which is used until a further network metric is determined by the first device.

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.

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: Method and apparatus of a user equipment (UE) device communicating during discontinuous reception (DRX). The UE may determine a data traffic pattern of an application executing on the UE. The UE may compare the data traffic pattern against a plurality of DRX configuration settings of a base station (BS). The UE may determine that the DRX configuration settings do not match the data traffic pattern. The UE may select a first DRX configuration setting based on the data traffic pattern. The UE may perform communication according to the first DRX configuration settings. The UE may transmit a scheduling request (SR) outside of a DRX on-duration according to the data traffic pattern. Transmitting the SR may be based on the DRX configuration settings not matching the data traffic pattern of the application. In response to transmitting the SR, the UE may receive downlink data of the application from the BS.

Abstract: Systems, apparatuses, and methods for messaging improvements in link budget limited devices. A link budget limited device may be configured to suppress or delay tracking area update messages in various situations. Additionally, or alternatively, the link budget limited device may be configured to transition to idle mode instead of performing handover or recovery from radio link failure when the target base station has a signal quality less than a threshold. Additionally, or alternatively, the link budget limited device may be configured to suppress or delay measurement reports in poor signal quality conditions.

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: Various mechanisms for paging link-budget-limited (LBL) devices are disclosed, including: (1) transmitting paging message with non-conventional paging identifier; (2) transmitting paging message(s) with increased power; (3) repeating transmission of paging message to support combining at receiver. Various mechanisms for UE device to signal LBL status are disclosed, including, transmitting status flag or special value of DRX cycle to network node as part of tracking area update and/or attach request. The network node informs a base station of the device's LBL status as part of a paging message. (The network node may, e.g., assign an S-RNTI to the LBL device from a reserved subset of S-RNTI space.) The base station invokes a paging enhancement mechanism when paging an LBL device. Alternatively, the base station may page UE devices without knowledge of LBL status, e.g., by counting paging attempts for a given UE, and boosting power after the Nth paging attempt.

The wireless device may communicate with the cellular base station in accordance with a modified communication configuration.

Abstract: Some embodiments relate to a user equipment device (UE), and associated methods for enabling the UE to estimate velocity of the UE based on cellular parameters. In some embodiments, a first velocity of a UE may be estimated based on a first set of parameters associated with one or more cellular based metrics. Doppler measurements may be performed in response to the first velocity exceeding a velocity threshold for at least a time period. In some embodiments, performing (or conducting) the Doppler measurements may be triggered by (e.g., in response to) the first velocity exceeding the velocity threshold for at least the first time period and receiving an indication from a motion processor of the UE that the UE is in a non-static state. In addition, a second velocity of the UE may be estimated based on the first set of parameters and the Doppler measurements.

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: This disclosure relates to cellular service recovery techniques using cell-specific cellular service history information for an accessory device. According to some embodiments, cellular service history information relating to cellular service loss occasions for each of one or more cells from which the accessory device has previously lost cellular service may be stored. It may be determined that cellular service loss is currently occurring from a cell for which cellular service history information relating to cellular service loss occasions is stored. Cellular service recovery may be attempted using the cellular service history information relating to cellular service loss occasions for the cell from which the current cellular service loss is occurring.
