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 network may include user equipment (UE) devices. When a first UE device becomes off-grid and has an emergency message, the first UE device may transmit device-to-device signals for receipt by a second UE device. The signals may include one or more preambles that precede the emergency message and that are used by the second UE device to perform synchronization with the first UE device. The second UE device may periodically activate a receiver during a series of windows to listen for the signals, may receive a preamble sequence during one of the windows, and may synchronize its timing to the first UE device for receipt of the emergency message based on the preamble sequence. This may allow the UE devices to be synchronized for transfer of the emergency message over long distances while consuming a minimal amount of power on the second UE device.

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: 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: 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.

Abstract: A user equipment (UE) device may communicate with an access point (AP) at greater than 100 GHz via a reconfigurable intelligent surface (RIS). The AP may perform a control RAT discovery with the RIS and then a data transfer RAT discovery, during which the AP uses the control RAT to control the RIS to sweep over different RIS beams. The AP may transmit radar waveforms while concurrently sweeping over different AP beams. The AP may gather performance metric values from the radar waveforms after reflection off the RIS during the sweep. The AP may identify an optimal RIS beam that produced the best performance metric values. The AP may use the optimal RIS beam to identify the orientation of the RIS, which the AP may use to select AP and/or RIS beams for conveying wireless data between the AP and the UE via the RIS.

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.
