Abstract: A wireless device, such as a user equipment device (UE), and a base station are disclosed, which may communicate with more efficient use of dynamic transmit time interval durations to enable a faster and more efficient ramp up of TCP communications to a higher or maximum throughput. The UE may communicate uplink or downlink communications with the base station according to a first shorter TTI duration for a first period of time. After the first period of time, the UE may communicate uplink or downlink communications to the base station according to a second longer TTI duration. For the case of uplink communications, the UE may be configured to increase a congestion window size after each acknowledgement of an uplink communication received by the base station during the first period of time. For the case of downlink communications, the base station may be configured to increase a congestion window size after each acknowledgement of a downlink communication received by the UE during the first period of time.

Abstract: A low-power scouting receiver is presented that provides an ability perform low-power scouting functions at a relatively low power. The low-power scouting functions determine context information for the receiver and enable fine-tuning of other receiver operations based on the context information. The low-power scouting functions include receiver control and switching, jammer detection, self-interference detection, or other context-dependent radio parameters.

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 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 circuitry configured to perform a computation that uses a matrix as an input and second circuitry configured to perform the computation, where the second circuitry includes a smaller amount of processing resources than the first circuitry. The second circuitry may begin performing the computation on at least a portion of a set of input data. One or more storage elements may store context information for the second circuitry, where the context information includes outputs from the computation performed on the at least a portion of the set of input data. Based on the at least a portion of the set of input data, the apparatus may activate the first circuitry to complete the computation, where the completion uses the outputs of the computation performed by the second circuitry, included in the context information, as an intermediate result.

Abstract: Methods and devices for creating and operating a combined network and computational slice instance (NCSI) in a Multi-access Edge Computing (MEC) scenario. Communication and computational resources may be reserved by a NCSI controller for the NCSI. The communication resources may include network slices and the computational resources may include MEC computational resources of one or more MEC servers. The reserved resources may be selected based on quality of service (QoS) requirements of UEs that will utilize the NCSI. During operation, reserved resources for the NCSI may be dynamically renegotiated based on an aggregate load of the NCSI, the QoS of data traffic, and/or updated QoS requirements of the UEs.

Abstract: A user equipment (UE) or other device performs service discovery of edge computing resources in a cellular network system and dynamic offloading of UE application tasks to discovered edge computing resources. As part of the discovery process, the device (e.g., the UE) may request edge server site capability information. When performing dynamic offloading, the UE may obtain (collect and/or receive) information regarding channel conditions, cellular network parameters or application requirements and dynamically determine whether a task of the application executing on the UE should be offloaded to an edge server or executed locally on the UE. In making decisions between offloaded or local execution, the UE may use a utility function that takes into account factors such as relative differences in application latency, energy consumption and offloading cost.

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.
