Resource Allocation for Communication via Reflective Surfaces - A simplified explanation of the abstract

This abstract first appeared for US patent application 18321698 titled 'Resource Allocation for Communication via Reflective Surfaces

Simplified Explanation

The patent application describes a controller that can map user equipment (UE) devices in a wireless system to access points (AP) and reflective intelligent surfaces (RIS). It generates a communications schedule based on the locations of the devices and current traffic demands, and controls the devices to implement the schedule. The schedule can use different access schemes to allocate resources efficiently. The RIS technology allows for a reduction in the number of APs needed, reducing costs.

  • The controller maps UE devices to APs and RISs in a wireless system.
  • It generates a communications schedule based on device locations and traffic demands.
  • The schedule can use space division, time division, frequency division, and distributed multiple-input and multiple-output schemes.
  • The schedule is updated as needed.
  • The RIS technology reduces the number of APs required, minimizing costs.

Potential Applications

This technology has potential applications in various wireless systems, including:

  • Cellular networks
  • Wi-Fi networks
  • Internet of Things (IoT) networks
  • Smart city infrastructure
  • Industrial wireless networks

Problems Solved

This technology addresses the following problems:

  • Efficient allocation of wireless resources in a dynamic environment
  • Minimizing the number of APs required for coverage and capacity
  • Reducing deployment and operating costs
  • Optimizing network performance based on traffic demands

Benefits

The benefits of this technology include:

  • Improved wireless network efficiency and capacity
  • Cost savings through reduced AP deployment and operating costs
  • Enhanced network performance and user experience
  • Flexibility to adapt to changing traffic demands and device locations


Original Abstract Submitted

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.
