This abstract first appeared for US patent application 18311782 titled 'METHOD AND DEVICE FOR BEAM TRAINING FOR AN INTELLIGENT REFLECTING SURFACE (IRS) ASSISTED CELLULAR SYSTEM

==Simplified Explanation==

- The patent application describes a method and device for beam training in a cellular system that uses an intelligent reflecting surface (IRS) to improve signal transmission.
- The method involves configuring the IRS to reflect a received beam in the same direction it was received, and determining an optimal beam pair for the link between the base station (BS) and the IRS.
- The IRS is also configured to receive a beam from the user equipment (UE), determine an optimal beam pair for the link between the IRS and the UE, and receive signaling information from the UE indicating the optimal beam pair.
- The BS then transmits a beam to the UE through the optimal beam pair determined for the BS-IRS link, and the IRS reflects this beam to the UE through the optimal beam pair determined for the IRS-UE link.
- This method and device aim to improve the efficiency and reliability of beam training in an IRS assisted cellular system.


==Original Abstract Submitted==

Disclosed is a method and device for beam training for an IRS assisted cellular system. The method performed by BS in the IRS assisted cellular system includes configuring the IRS in a retro-reflection mode to reflect a received beam in same direction of reception of the beam and determining a BS optimal Tx-Rx beam pair for a BS-IRS link. The method includes: configuring the IRS to receive a beam from the UE; configuring the IRS to determine an IRS optimal Tx-Rx beam pair for an IRS-UE link and receiving signalling information from the UE indicating the IRS optimal Tx-Rx beam pair; and transmitting to the UE, a beam through the BS optimal Tx-Rx beam pair which is received at the UE through the UE optimal Tx-Rx beam pair, wherein the IRS reflects the beam transmitted by the BS to the UE through the IRS optimal Tx-Rx beam pair.
