Abstract: A user equipment (UE) device may communicate with an access point (AP) at greater than 100 GHz via a reconfigurable intelligent surface. The UE may select tracking beams based on sensor data. The UE may instruct the RIS to sweep over the tracking beams while the UE gathers performance metric data. The UE may identify a serving beam based on the performance metric data. The UE may control the RIS to form the serving beam to reflect wireless data between the AP and the UE. Using the UE to intelligently select tracking beams based on sensor data may greatly reduce the amount of time required to track the UE device as it moves relative to sweeping over all formable signal beams, thereby reducing latency and minimizing disruptions in wireless data transfer between the UE device and the AP.

Abstract: A communications system may include a user equipment (UE) device that communicates with a wireless network. The UE device may transmit a signal to the wireless network identifying a peak data rate of a modem on the UE device, a balanced data rate of the modem, and a buffer size of the modem. The UE device may receive downlink data from the wireless network and may store the downlink data at buffer circuitry on the modem. The UE device may perform delayed processing of the downlink data across slots in a manner that allows for a reduction in size of the modem.

Abstract: A user equipment (UE) device may communicate with a wireless access point (AP) via reflection off a reconfigurable intelligent surface (RIS). The RIS may begin to sweep antenna elements over one or more sets of signal beams beginning at an initial time while reflecting signals transmitted by the AP. The UE may record times at which the UE receives reference signals reflected by the RIS. The UE may select an optimal signal beam of the RIS based on the time periods between the initial time and the times at which the reference signals were received. The UE may inform the AP of the optimal signal beam and the RIS may use the optimal signal beam to reflect wireless data between the AP and the UE. Multiple signal beam sweeps may eliminate uncertainty or ambiguity in signal beam selection associated with timing drift or offsets between the RIS and the UE.

Abstract: A method of communicating between a physical control device and an electronic device is disclosed herein, the physical control device having a plurality of conductive protrusions detectable by a touch screen of the electronic device when placed in contact with the touch screen. The method comprises identifying, via the electronic device, the physical control device in contact with the touch screen based on a conductive pattern of the conductive protrusions detected by a capacitive touch sensor panel of the touch screen. The method further includes performing a first action at the electronic device in accordance with an input to the physical control device that causes a change in a characteristic of the conductive pattern of the plurality of conductive protrusions detected by the capacitive touch sensor panel, and ignoring a touch input at the capacitive touch sensor panel from a housing of the physical control device.

Abstract: Aspects of the subject technology relate to communication device used as a power meter. The communication device includes circuitry to determine values of several forces and a processor. The processor determines a combined force by combining the determined values of the forces. The processor further determines a value of a power based on the s combined force, a speed and a loss factor. The communication device is used by a user to measure the power. The power is generated by the user when engaged in an activity, and the forces affect a movement of the user.

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: Methods, systems, and circuitries are provided to generate clock signals of different qualities in a device. A method includes determining whether the device is operating in a mid power mode or a high power mode. In response to determining that the device is operating in the mid power mode, oscillator circuitry is controlled to cause the oscillator circuitry to consume a lower amount of power, such that the oscillator circuitry generates a lower quality clock signal. In response to determining that the device is operating in the high power mode, the oscillator circuitry is controlled to cause the oscillator circuitry to consume a higher amount of power, such that the oscillator circuitry generates a higher quality clock signal. The lower amount of power and the higher amount of power are different from one another.

Abstract: Circuits, methods, and apparatus that can route signals for wireless communications throughout an electronic device in an efficient manner that can save space, reduce noise, improve coexistence, and be readily assembled. An example can route signals through an electronic device using a bus, ring, or daisy-chain topology. Use of this topology can simplify routing, thereby saving space that can be used for additional functionality for the electronic device, a reduction in size of the electronic device, or both. Fiber-optic segments can be used for signal routing to decrease noise.

Abstract: A communication system may include an access point (AP), a user equipment (UE), and a communication path between the AP and the UE having a series of reconfigurable intelligent surfaces (RIS's). Each RIS may have a first beam pointing to a previous node and a second beam pointing to a next node in the communication path. Beams of routing RIS's and a beam from an end user RIS towards a last routing RIS may be set during calibration. The UE may perform beam discovery with the end user RIS. The UE and the AP may convey wireless data via reflections off each of the RIS's in the communication path. The beam of the end user RIS may be updated to track the UE device while the other the beams remain fixed. The beams may be calibrated using retroreflection and beam variation for each pair of RIS's up the communication path.

Abstract: A controller may map user equipment (UE) devices in a wireless system to access points (AP) and reflective intelligent surfaces (RIS). The controller may generate a corresponding communications schedule based on the locations of the UE device(s), AP(s), and RIS(s) and based on current traffic demands. The controller may control the RIS(s), AP(s), and UE devices to implement the schedule. The schedule may divide the time, frequency, and/or spatial resources of the RIS(s) to meet the traffic demands of the UE devices using a space division multiple access scheme, a time-division multiple access scheme, a frequency-division multiple access scheme, and/or a distributed multiple-input and multiple output scheme. The schedule may be updated over time as needed. The RIS(s) may allow for a reduction in the number of AP(s) required to meet the dynamic demands of the UE devices, thereby minimizing deployment and operating costs.
