    Abstract: A user equipment (UE) device may communicate according to a new device category satisfying specified QoS (quality of service) requirements while also satisfying specified link budget requirements, and/or additional optimization requirements. The UE device may communicate with a cellular base station according to a first mode of operation associated with the new device category, and may switch to communicating with the cellular base station according to a second mode of operation associated with a second (pre-existing) device category in response to the link budget requirements exceeding a specified value and the quality of service requirements not being sensitive. The UE device may also switch to communicating with the cellular base station according to a third mode of operation associated with a third (pre-existing) device type in response to the link budget requirement not exceeding the specified value, or the QoS requirements being sensitive and a downlink throughput requirement exceeding a specified throughput value.

    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 including information in a data packet transmitted by a transmitting integrated circuit (e.g., SOC) to account for a time delay associated with an unsuccessful arbitration attempt to send the data packet over a multi-drop bus. The unsuccessful arbitration attempt by the integrated circuit may delay the transmission of the data packet until the multi-drop bus becomes available for the integrated circuit to send the data packet. The data packet includes a data field to include time delay information caused by the unsuccessful arbitration attempt. A receiving integrated circuit may determine the time that the data packet would have been sent out from the transmitting integrated circuit absent the unsuccessful arbitration attempt based on the delay information. Embodiments also relate to a synchronization generator circuit in an integrated circuit that generates timing signals indicating times at which periodic events occur at another integrated circuit.

    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: 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.
