Communication via Uplink and Downlink Reflective Devices - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240250741 titled 'Communication via Uplink and Downlink Reflective Devices
The communication system described in the patent application includes a base station (BS), user equipment (UE), and a set of reconfigurable intelligent surfaces (RIS's). The RIS's, UE, and BS communicate using a control rat and a data rat. The BS transmits downlink (DL) signals to the UE device via reflection off a DL RIS, while the UE device transmits uplink (UL) signals to the BS via reflection off a UL RIS. This optimization of wireless performance is particularly useful when reflecting the UL and DL signals off the same RIS would limit performance under current channel conditions.
- The system utilizes reconfigurable intelligent surfaces (RIS's) to optimize wireless performance.
- DL signals are transmitted from the BS to the UE via reflection off a DL RIS.
- UL signals are transmitted from the UE to the BS via reflection off a UL RIS.
- Channel measurements of the control rat at the RIS's are used to select the UL and DL RIS's.
- This approach significantly reduces overhead compared to exhaustive beam training methods.
Potential Applications: - 5G and beyond wireless communication systems - Smart city infrastructure - Internet of Things (IoT) networks
Problems Solved: - Optimization of wireless performance in challenging environments - Reduction of overhead in selecting RIS's for signal reflection
Benefits: - Improved wireless communication efficiency - Enhanced network reliability - Increased data transfer speeds
Commercial Applications: Title: Reconfigurable Intelligent Surfaces for Enhanced Wireless Communication This technology can be applied in telecommunications, smart infrastructure development, and IoT networks, offering improved connectivity and performance.
Questions about Reconfigurable Intelligent Surfaces for Enhanced Wireless Communication: 1. How does the use of RIS's impact overall network performance? The use of RIS's optimizes wireless performance by enabling efficient signal reflection and transmission, ultimately enhancing network reliability and data transfer speeds.
2. What are the potential challenges in implementing RIS technology in existing communication systems? Implementing RIS technology may require infrastructure upgrades and compatibility considerations with existing network components. However, the benefits of improved wireless performance justify the investment in integrating RIS's into communication systems.
Original Abstract Submitted
a communication system may include a base station (bs), user equipment (ue), and a set of reconfigurable intelligent surfaces (ris's). the ris's, the ue, and the bs may communicate using a control rat and a data rat. the bs may transmit downlink (dl) signals to the ue device via reflection off a dl ris. the ue device may transmit uplink (ul) signals to the bs via reflection off a ul ris. this may optimize wireless performance in situations where reflecting the ul and dl signals off the same ris would limit performance under the current data rat channel conditions. the bs and the ue device may use channel measurements of the control rat at the ris's to select the ul ris and the dl ris. this may significantly reduce overhead required to identify the ul and dl ris's relative to scenarios where exhaustive beam training is used.
