US 2024/0405807 A1 · SYSTEMS AND METHODS FOR BEAM SPOT ALIGNMENT ON RECONFIGURABLE INTELLIGENT SURFACE IN COMMUNICATION SYSTEMS

Abstract

Aspects of the disclosure include configuring beams of a transmitter and a receiver so that the beam spots from the different nodes overlap, such that the received signals of one or more nodes satisfy a service requirement such as rate value, a gain value or a SNR value, at a reconfigurable intelligent surface (RIS) that is used to redirect a signal between the different nodes. Examples of the transmitter and the receiver may be a base station and one or more user equipment (UE) in a downlink or uplink direction or between two UEs in a sidelink direction. Another aspect of the disclosure is providing control signaling in order to configure the overlapping area of the beam spots. For example, signaling information pertaining to one or more beam parameters is exchanged between the transmitter and the receiver in order to facilitate the beamforming that is performed at each device.

Dependent claims

A method at a side of a user equipment (UE), comprising:

receiving first configuration information, the first configuration information comprising information for improved overlap of a first beam spot of a first beam of a base station (BS) and a second beam spot of a second beam of the UE, the first beam spot and the second beam spot both impinging on a reconfigurable intelligent surface (RIS) for transmitting or receiving signals between the base station and the UE;
and
reconfiguring the UE based on the first configuration information.

A device at a side of a user equipment (UE), comprising:

at least one processor;
and
a computer-readable medium having stored thereon, computer executable instructions, that when executed by the at least one processor, cause the device to perform operations including:
receiving first configuration information, the first configuration information comprising information for improved overlap of a first beam spot of a first beam of a base station (BS) and a second beam spot of a second beam of the UE, the first beam spot and the second beam spot both impinging on a reconfigurable intelligent surface (RIS) for transmitting or receiving signals between the base station and the UE;
and
reconfiguring the UE based on the first configuration information.
