    Abstract: A full-duplex radio device is disclosed. The full-duplex radio device includes an analog transmission (TX) circuit that includes a power amplifier to output an analog TX signal. The full-duplex radio device also includes a feedback receiver circuit coupled to the analog TX circuit. The feedback receiver circuit provides a digital representation of the analog TX signal that is used to digitally cancel at least a transmitter noise component of a self-interference signal associated with a transmission of the analog TX signal in the full-duplex radio device.

    Abstract: A system may include a client device running multiple client-side applications and server equipment running multiple server-side applications. One or more traffic aggregators may be provided between the client-side applications and the server-side applications. Each traffic aggregator may aggregate application traffic from the multiple applications to form one or more classes of aggregated data. Interfaces may be provided between the traffic aggregators and the applications to customize application traffic. Traffic aggregators in the system may be dynamically updated.

    Abstract: A primary device may run a software application requiring a compute task. The primary device may receive statistics from a set of secondary devices over wireless communication links. The statistics may include parameters associated with the compute and communication capabilities of the secondary devices. The primary device may predict, based on the statistics, an expected performance gain in distributing the compute task to the secondary devices relative to performing the compute task locally. If the expected performance gain is high enough, the primary device may distribute shares of the compute task to the secondary devices over the wireless communication links. If the expected performance gain is low enough, the primary device may perform the compute task locally. If the expected performance gain is moderate, the primary device may update the set of secondary devices and/or may update a coding and distribution scheme for the compute task.

    Abstract: A communication system may include an electronic device, one or more external devices, and one or more reconfigurable intelligent surfaces (RIS's). Wireless signals may be incident upon the RIS(s) from the external device(s). The RIS(s) may have antenna elements that reflect the signals towards the electronic device while being swept over a set of reflected angles. The device may include one or more antennas that receive the reflected wireless signals. The device may perform measurements of the received wireless signals and may generate a steering vector using the measurements. The device may input the steering vector to a super-resolution algorithm that outputs angles-of-arrival of the wireless signals at the RIS(s), which can be used to detect the position of the external device(s). The device may receive the wireless signals using a single antenna to minimize resource and space consumption or using multiple antennas to maximize location accuracy.

    Abstract: A method performed by a client device is provided. The method includes obtaining, by a client device, data for transmission to a network server. The method includes determining, by the client device, a plurality of intermediate network nodes for transmission of the data, wherein the plurality of the intermediate network nodes are communicatively coupled to the network server. The method includes encoding, by the client device, the data using an encoding scheme. The method includes transmitting, by the client device and according to a data transmission scheme, a plurality of instances of the encoded data to the plurality of intermediate network nodes for aggregation by the intermediate network nodes with data received from one or more other client devices. Also provided are methods performed by an intermediate network node and a network server. The methods can be performed by one or more processors of an apparatus.

    Abstract: A primary device may run a software application requiring a compute task. The primary device may receive statistics from a set of secondary devices over wireless communication links. The primary device may process the statistics to determine whether the compute task will be offloaded to the secondary devices or performed locally. The primary device may generate a distribution scheme for the secondary devices based on the statistics. This may involve modeling first delays associated with transmission of signals from the primary device to the secondary devices, second delays associated with transmission of compute results from the secondary devices to the primary device, and third delays associated with processing resources of the secondary devices. The optimized distribution scheme may minimize overall runtime of the compute task given the modeled delays, scheduling grants for the secondary devices, and a radio resource allocation for the secondary devices.

    Abstract: An electronic device may include wireless circuitry having one or more radios and one or more antennas. A first radio may be configured to establish a communication link with an external device, a second radio may be configured to establish a communication link with network equipment. One or more processors in the electronic device may receive information indicative of a duration and termination of the communication link with the external device to operate the second radio in one or more operational modes. If desired, one of the operational modes may include a low-power idle mode during which the second radio performs discontinuous reception while pausing network paging monitoring.
