Abstract: A wireless access point (AP) may communicate with a user equipment (UE) device via reflection off a reflective device having an array of fixed or adjustable reflectors in different orientations. The AP may illuminate different portions of an area by pointing a signal beam to different reflectors and/or by controlling the reflective device to electrically rotate the reflectors. The AP may calibrate the position of the reflective device and may establish wireless communications with the UE device by performing a sweep of signal beams over the reflectors and/or by controlling the reflective device to sweep over different reflector orientations. The AP may track movement of the UE device over time. The AP may sweep the AP beam over a subset of the reflectors around an active reflector to maintain communications with the UE device even as the UE device moves over time.

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.

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: A user equipment (UE) device may communicate with a wireless access point (AP) using wireless signals transmitted using a data radio access technology (RAT) via reflection off a reconfigurable intelligent surface (RIS) at frequencies greater than about 100 GHz. A control RAT may be used to convey control signals between the AP, UE device, and RIS. The control signals and the control RAT and the data transfer RAT may split procedures used to perform discovery, to establish an initial configuration of the UE device, AP, and/or RIS, and to update the configuration of the UE device, the AP, and/or the RIS while tracking the UE device over time. The control RAT may allow for control operations without requiring line-of-sight and may allow the RIS to minimize its power consumption and cost.

Abstract: The present application relates to devices and components, including apparatus, systems, and methods for discovering and establishing highly directional wireless communication link through other devices with established highly directional communication link to an access point. Devices with established link to the access point may exchange beam information (BI) or geometry or location indication (GI) between the AP and devices seeking to be connected to the AP. The exchange of BI and GI may expedite link establishment between the AP and devices without connection to the AP.

Abstract: Disclosed are methods, systems, and computer-readable medium to perform operations including: receiving, from a remote device, a reference signal for each of one or more synchronization signal blocks (SSBs); responsive to the receiving, selecting a receiver (Rx) beam from a set of candidate receiver (Rx) beams, the selecting being based on a sweep of the candidate Rx beams and on measuring the reference signal with one or more of the candidate Rx beams of the set of the candidate Rx beams; and communicating, using the selected Rx beam, an element of common control signaling (CCS) information to the remote 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 system may include an access point (AP), a user equipment (UE) device, and a reconfigurable intelligent surface (RIS). The RIS may have antenna elements and phase shifters programmed using phase settings to form signal beams. The AP may calculate a first portion of the phase settings and may transmit the first portion to the RIS. The RIS may include a first processor that generates a second portion of the phase settings. The RIS may include a second processor coupled to the first processor over a bus. The second processor may generate the phase settings based on the second portion. The second processor may distribute the phase settings to the phase shifters. By distributing calculation of the phase settings between the AP and the RIS, power consumption of the system may be minimized while also minimizing the time required to re-configure the beams of the RIS.

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.
