Title:
SYSTEM AND METHOD FOR MANAGING BEAM FAILURE RECOVERY IN HIGH-FREQUENCY COMMUNICATION SYSTEMS USING RIS
Document Type and Number:
WIPO Patent Application WO/2024/043621
Kind Code:
A1
Abstract:
A method of beam failure recovery managed by a transmitter of a communication system, includes: detecting a first occurrence of a beam failure between the transmitter and a receiver; based on the detection of the first occurrence of the beam failure, identifying at least one first reconfigurable intelligent surface (RIS) for transmitting at least one reference signal; transmitting the at least one reference signal to the at least one first RIS; receiving, from the at least one first RIS, a receiver feedback for the at least one of reference signal; generating an RIS candidate beam list based on the receiver feedback; and transmitting, to the receiver via the at least one first RIS, a radio resource control (RRC) message including the RIS candidate beam list as a beam failure recovery configuration.
