APPARATUS AND METHOD FOR SUPPORTING SYNCHRONIZATION OF RECONFIGURABLE INTELLIGENT SURFACE (RIS) REFLECTION PATTERN IN WIRELESS COMMUNICATION SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18476788 titled 'APPARATUS AND METHOD FOR SUPPORTING SYNCHRONIZATION OF RECONFIGURABLE INTELLIGENT SURFACE (RIS) REFLECTION PATTERN IN WIRELESS COMMUNICATION SYSTEM

Simplified Explanation

The present disclosure pertains to a communication system that supports higher data rates beyond 4G systems like LTE, specifically focusing on synchronization of signals transmitted to a reconfigurable intelligent surface (RIS) in a wireless communication system.

  • Method performed by a base station:
   * Identify delay time caused by a radio unit (RU) buffer.
   * Determine an RIS offset value for signal synchronization based on the delay time.
   * Transmit a first signal to the RIS for reflection to a terminal at a specific time point.
   * Transmit a second signal to control the reflection pattern of the RIS at another time point with the applied RIS offset value.

Original Abstract Submitted

The present disclosure relates to a fifth generation (5G) communication system or a sixth generation (6G) communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). In a wireless communication system, a method performed by a base station includes identifying a delay time caused by a radio unit (RU) buffer, determining an RIS offset value for synchronization of signals transmitted to a reconfigurable intelligent surface (RIS), based on the delay time caused by the RU buffer, transmitting, to the RIS, a first signal to be transmitted to a terminal through a reflection plane of the RIS at a first time point, and transmitting, to the RIS, a second signal for controlling a reflection pattern of the RIS at a second time point to which the RIS offset value is applied.
