Abstract: Apparatuses, systems, and methods for using an assistance information framework to perform fast carrier aggregation and dual connectivity configuration. A wireless device may provide assistance information for determining a carrier aggregation or dual connectivity configuration to a cellular base station. The assistance information may be provided while establishing a radio resource control connection. The assistance information may include either or both of carrier aggregation or dual connectivity preference information for the wireless device or service data amount information for the wireless device. The cellular base station may select a carrier aggregation or dual connectivity configuration for the wireless device based on the assistance information, and may provide configuration information for the selected configuration to the wireless device.

Abstract: A device, system, and method uses a high power mode for a cellular connection. The method is performed at a device that is configured to establish a network connection to a network. The method includes detecting a number of at least one event that has occurred over a time period, the at least one event associated with operations used through the network connection, the at least one event indicative of a power to perform the operations that is greater than a predetermined power. When the number is at least a predetermined threshold, the method includes identifying the network connection as being in a high power state. The method includes activating settings when the network connection is in the high power state, the settings reducing a usage of the operations over the network connection.

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.

Abstract: This disclosure relates to techniques for network delaying cellular re-registration during critical conditions. A wireless device may register for cellular service with a cellular network. The wireless device may receive a configuration update command from a network element of the cellular network. The configuration update command may request re-registration of the wireless device. The wireless device may determine to delay responding to the configuration update command based at least in part on one or more conditions in effect at the wireless device. For example, one possible such condition may include if a protocol data unit session associated with emergency services is active at the wireless device.

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 dynamically changing coverage modes and/or communication bandwidth in a wireless communication system. According to some embodiments, a wireless device may attach to a serving cell associated with a cellular network. A volume of data for upcoming communication with the cellular network may be determined. An indication of a requested communication bandwidth may be provided to the serving cell. The wireless device may communicate data with the serving cell using the requested communication bandwidth. In some instances, a request for narrowband communication bandwidth may result in use of a coverage enhancement mode, while a request for wideband communication bandwidth may result in use of a normal coverage mode.

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.
