Abstract: A communications network may include a relay device that receives device-to-device (D2D) signals. In an ad hoc mode, the relay may consume relatively little power while receiving relatively few messages from relatively few transmitting devices in the D2D signals. In an organized mode, the device may consume relatively high power while receiving many messages from many transmitting devices in the D2D signals. A receiver on the device may transition from the ad hoc mode to the organized mode in response to a first criterion and may transition from the organized mode to the ad hoc mode in response to a second switching criterion. This may allow the device to balance communications load and power consumption while relaying messages such as emergency messages received over D2D signals given that the signals may arrive rarely or in clusters due to an unforeseen event.

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: 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: 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.
