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: Embodiments relate to an integrated circuit of an electronic device that coordinates activities with another integrated circuit of the electronic device. The integrated circuit includes an interface circuit and a processor circuit. The interface circuit communicates over a multi-drop bus connected to multiple electronic components. The processor circuit receives an authorization request from the integrated circuit via the interface circuit and the multi-drop bus. The received authorization request relates to authorization to perform an activity on the other integrated circuit. In response to receiving the authorization request, the processor circuit determines whether the other integrated circuit is authorized to execute the activity. In response to determining that the other integrated circuit is authorized to execute the activity, the processor circuit sends, to the other integrated circuit over a configurable direct connection, an authorization signal authorizing the other integrated circuit to execute the activity.

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: Described is a user equipment (UE) that is connected to a network component, the user equipment and the network component configured with a carrier aggregation functionality. The UE performs a method that includes determining a primary component carrier and at least one secondary component carrier associated with the carrier aggregation functionality of the user equipment, determining a component carrier quality measurement (CQM) metric for each of the component carriers, when an uplink data packet is capable of being transmitted over the secondary component carrier, selecting one of the primary component carrier and the at least one secondary component carrier based on the CQM metrics, generating measurement data indicative of the selected component carrier to increase a probability to transmit the uplink data packet over the selected component carrier and transmitting the measurement data to the network component.
