Abstract: A cellular communications system may include a user equipment (UE) that executes a target and non-target applications. The UE may convey a first stream of non-quality-of-service (QoS) wireless data with a first external device over a first Transmission Control Protocol (TCP) session and may receive a second stream of non-QoS wireless data from a second external device over a second TCP session. Responsive to a drop in data rate of the first stream, the UE may perform mitigation operations that adjust receipt of the second stream to boost the data rate of the first stream. The mitigation operations may include transmission of a triple duplicate acknowledgement (TDA), delayed transmission of an acknowledgment (ACK) to the second stream, and/or terminating the second TCP session. This may prevent disruptions to user experience with the first software application even when the network has downlink data to transmit to the UE.

Abstract: Systems, methods, and processors are provided for supporting a distributed computing framework. In one example, a wireless communication device is configured to act as a distributed computing control node (ContN), the wireless communication device including a memory and a processor coupled to the memory. The processor is configured to, when executing instructions stored in the memory, cause the device to receive respective registration messages from respective wireless communication devices. The registration messages include registration information indicating whether a respective wireless communication device acts as an offload node (OffN) for distributed computing or a compute node (CompN) for distributed computing. The processor is configured to store the registration information in a resource repository and, based on the registration information of the respective wireless communication devices, transmit a resource availability message indicating available distributed computing resources to wireless communication devices acting as OffNs.

Abstract: This disclosure provides various techniques for decreasing the time it takes user equipment to tune away from a compromised network connection. By more quickly detecting a signal characteristic issue (e.g., signal quality issue) in the compromised signal and performing mitigation actions, the user equipment may decrease power consumption and increase data throughput. The signal quality issue may be detected by monitoring the location of the user equipment, a channel impulse response of the user equipment, and/or a block error rate (BLER) of a signal, among other methods. The data obtained may be fed into confidence validation logic, which may determine a level of confidence that the signal quality issue may cause a weak or broken connection between the user equipment and a network. The confidence validation logic may, based on the determination, operate the user equipment in an active state, a suspend state, or a release state.

Abstract: Embodiments herein provide various apparatuses and techniques to for enhanced handling of receiver desensitization, “desense,” in electronic devices that is caused by an operation of the device. In an embodiment, sensitivity of a receiver affected by desense may be determined based on receiver sensitivity without desense and a desense offset value. Desense mitigation measures may be applied based on the strength of the signal received by the receiver being less than the receiver sensitivity affected by desense. The desense mitigation measures may include deactivating the device operation that causes desense, enabling the device operation that causes desense only during certain times, and enabling antenna diversity. In some embodiments, various power and signal-to-noise ratio thresholds may be used for conditional application of different desense mitigation measures. For example, to enable receiver diversity on the device, strength of the signal needs to be below one power threshold and above another power threshold.

Abstract: Methods and devices for a user equipment (UE) device to utilize an electronic subscriber identity module (eSIM) to provide backup cellular connectivity for essential services and security enhancements. A UE device receives user input to alter an operational state of the UE. The user input may include removing a physical subscriber identity module (SIM) card installed in the UE or attempting to power off the UE. In response to receiving the user input, an authorization process is initiated. In response to determining that the authorization process has failed, a security enhancement is implemented for the UE.

Abstract: User equipment in close proximity may transfer data and control information. For example, the user equipment may exchange data or data sets between each other. Each user equipment can receive and transmit data using radio access technologies. A group of user equipments may include active user equipment and passive user equipment. Active user equipment connects with one or more base stations and transfers data on a wireless communication network via the base station. The active user equipment may communicate with other active user equipment and passive user equipment. Passive user equipment may not connect to any base station and/or the wireless communication network and may communicate with other passive user equipment and active user equipment (e.g., via a sidelink, peer-to-peer, or device-to-device channel).

Abstract: An electronic device determines a position of a communicaiton hub of a wireless network. In response to determining a position of a communication hub of a wireless communication network, the electronic device may operate one or more actuators to move the device to adjust the orientation of the device relative to the communication hub. As such, the mobile communicating device may adjust the orientation of the device relative to the communication hub to provide more reliable and/or more efficient communication of data.

Abstract: A mobile communication device is configured to receive updated network data, such as updated Content Delivery Network (CDN) data utilized to access a first network, without accessing the first network and a second network, such as a Wi-Fi or cellular network. The mobile communication device periodically transmits, via a peer-to-peer (P2P) network, a beacon signal indicating a network data request for the updated network data. A rate at which the mobile communication device periodically transmits the beacon signal is based on various criteria, such as an origination date of network data stored on the mobile communication device, an amount of time between the origination date and the present date, a battery health of the mobile communication device, and/or various inputs to the mobile communication device. An additional mobile communication device receives the beacon signal and transmits the updated network data to the mobile communication device.
