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: This disclosure relates to providing coexistence features for cellular communication in unlicensed spectrum. A wireless device may communicate with a cellular base station in accordance with an original communication configuration. The wireless device may determine that a communication activity is occurring at the wireless device that has a duration longer than a duration threshold. The wireless device may provide an indication to the cellular base station to modify the communication configuration with respect to operation in an unlicensed frequency band based at least in part on determining that a communication activity is occurring at the wireless device that has a duration longer than the duration threshold. The wireless device may communicate with the cellular base station in accordance with a modified communication configuration.

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 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: 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: 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.
