Document Type and Number:
WIPO Patent Application WO/2024/053947
Kind Code:
A1
Abstract:
The present disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). In an embodiment of the disclosure, the method performed by a base station is provided. The method comprises transmitting to an UE a RS for at least one of a direct BS candidate beam and an RIS candidate beam and receiving from the UE a measurement report comprising a RSRP. In case that the RSRP meets the RSRP criteria, the method comprises selecting a first mode configuration for the RIS among a plurality of mode configurations for the RIS based on a link between the BS and the UE. The method comprises switching from the RIS candidate beam to direct BS candidate beam and scattering the multiple beams from the RIS in different directions.
