Abstract: A method and apparatus according to the present invention addresses and/or prevents lost protocol synchronization in HARQ systems caused by ACK/NACK errors. One embodiment detects lost synchronization errors for NDI-based retransmission protocols and restores synchronization by sending an explicit RESET message. In response to the RESET message, the transmitter aborts the transmission of a current PDU and transmits a new PDU and corresponding NDI. Another embodiment prevents protocol synchronization errors by sending scheduling grants on a packet by packet basis. The receiver sends a subsequent explicit scheduling grant to the transmitter based on an error evaluation of a received PDU. The transmitter will not send the next PDU unless it receives the subsequent explicit scheduling grant.

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 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.

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 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.
