Abstract: A wireless communication device (UE) may provide information pertaining to one or more operating capabilities of the UE to LTE and 5G-NR networks. The UE may transmit information to an LTE base station directly, and to a 5G-NR base station directly, or indirectly via the LTE base station. The information may include preferred values corresponding to any number of different operating parameters associated with wireless communications or wireless communication capabilities of the UE in both LTE and 5G-NR networks, to inform and/or request the LTE and 5G-NR networks to make provisions based on the transmitted information for the wireless communications of the UE on those networks. The UE may thereby provide assistance information to LTE and 5G-NR networks in a multi-radio-access-technology dual-connectivity setting to request the respective networks to adjust certain operating capabilities of the UE in order to alleviate one or more operating issues that may be affecting the UE.

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: Embodiments relate to a billboard circuit that stores context information received from various component circuits in an electronic device. The context information indicates an operating status of the corresponding component circuit, system or shared resources. The stored context information may be retrieved by one or more component circuits when events (e.g., turning on of a component circuit) are detected. By using the billboard circuit, a component circuit may detect changes in the operating status of other components circuits and configure or update its operations even when the changes occurred while the component circuit was asleep or disabled. The billboard circuit may monitor updating of the context information by the component circuit and initiate notification to other components circuits when certain entries of the context information is updated.

Abstract: Embodiments relate to coordinating the operations of subsystems in a communication system of an electronic device where a coexistence hub device monitors the state information transmitted as coexistence messages over one or more multi-drop buses, processes the monitored coexistence messages and sends out control messages as coexistence messages to other systems on chips (SOCs). The coexistence hub device can also update the operations of the communication system. The coexistence hub device may receive an operation policy from a central processor and may execute the operation policy without further coordination of the central processor. The coexistence hub device broadcasts the control messages as coexistence messages according to the executed operation policy.

Abstract: In some embodiments, an apparatus includes first and second signal processing circuitry configured to perform signal processing operations and second signal processing circuitry configured to perform signal processing operations, wherein the second signal processing circuitry includes a smaller amount of processing resources than the first signal processing circuitry. In some embodiments, the apparatus includes one or more storage elements configured to store context information for the second signal processing circuitry and the one or more storage elements are accessible to the first signal processing circuitry. The apparatus may be configured to select one of the first and second signal processing circuitry based on the complexity of input problems, the amount of transmission resources assigned to the apparatus, etc. In some embodiments, intermediate results of from the second signal processing circuitry are used as inputs to an operation performed by the first signal processing circuitry.

Abstract: In some embodiments, a wireless device such as a user equipment (UE) may communicate with a base station using an advanced form of carrier aggregation. The UE may provide signaling to the network specifying a number P of downlink component carriers to be configured for use by the UE for downlink carrier aggregation and a number Q of uplink component carriers to be configured for use by the UE for uplink carrier aggregation. The UE can only utilize a lesser number M of downlink component carriers at any given time in downlink carrier aggregation and can only utilize a lesser number N of uplink component carriers at any given time in uplink carrier aggregation. Thus the UE may request the network to configure a greater number P and Q of downlink and uplink component carriers, respectively, than the UE can actually use at any instant of time.

Abstract: An apparatus, system and method for determining whether a battery alarm of a UE is asserted, reducing a transmission duty cycle of the UE to zero for a first predetermined time period when the battery alarm is asserted, determining whether the battery alarm has been de-asserted after the first predetermined time period and when the battery alarm has not been de-asserted, increasing the transmission duty cycle to a first threshold level for a second predetermined time period, wherein the first threshold level is less than a full transmission duty cycle of the UE. When the battery alarm has been de-asserted, increasing the transmission duty cycle to a second threshold level for a third predetermined time period, wherein the second threshold level is less than the full transmission duty cycle of the UE, and wherein the second threshold level is greater than the first threshold level.

Abstract: This disclosure relates to techniques for supporting narrowband device-to-device (D2D) wireless communication, including possible techniques for providing synchronization and master information block signals in an off grid radio system. A wireless device may provide D2D synchronization signals for a D2D communication group. The D2D synchronization signals may be provided using multiple frequency channels. The D2D synchronization signals may be provided on each respective frequency channel of the frequency channels during a respective portion of a D2D synchronization signal cycle in a sequential manner.
