RECONFIGURABLE INTELLIGENT SURFACE-ASSISTED FLEXIBLE WIRELESS NETWORK

原文（中文）

The technology described herein is directed towards subdividing a reconfigurable intelligent surface into subarrays, or rectangular segments of unit cells, for different functions/operations. The subdividing can be dynamic, such as based on different performance-based allocations, and each segment can have a separate directivity or array gain. Control signal data from a base station or user equipment instructs a controller of the reconfigurable intelligent surface to change the respective numbers of unit cells for the various respective functions/operations, which can include a receive-and-forward function from the base station via the reconfigurable intelligent surface to user equipment, and a receive-and-forward function from the user equipment via the reconfigurable intelligent surface to the base station. There can be one subarray for receiving control information at the reconfigurable intelligent surface from the base station, and one subarray for transmitting control information back to the base station.
