Title:
METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING BEAM RELATED INFORMATION IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/270990
Kind Code:
A1
Abstract:
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. In the disclosure, method and apparatus for a beam indication and a beam update for an inter-cell operation is provided. The method includes receiving a first DCI including a first TCI codepoint indicating a first TCI states and a second DCI indicating a second TCI codepoint indicating second TCI states. The method further includes determining, based on the first TCI states, first QCL information for receipt of a first PDCCH, PDSCH, or CSI-RS and determining, based on the second TCI states DCI, second QCL information for receipt of a second PDCCH, PDSCH, or CSI-RS. The method further includes receiving the first PDCCH, PDSCH, or CSI-RS based on the first QCL information and the second PDCCH, PDSCH, or CSI-RS based on the second QCL information.
