Title:
METHOD AND APPARATUS FOR SENDING TRANSMISSION CONFIGURATION INDICATOR, METHOD AND APPARATUS FOR RECEIVING TRANSMISSION CONFIGURATION INDICATOR, STORAGE MEDIUM, BASE STATION, AND TERMINAL
Document Type and Number:
WIPO Patent Application WO/2019/233334
Kind Code:
A1
Abstract:
A method and apparatus for sending a transmission configuration indicator (TCI), a method and apparatus for receiving TCI, and a storage medium, a base station, and a terminal. The sending method comprises: determining a target reference signal, and determining port groups corresponding to a resource occupied by the target reference single, large-scale parameters of ports in different port groups being different; for each port group of the target reference signal, determining a source reference signal in quasi-co-location with the port group, and a quasi-co-location type of the quasi-co-location between the each port groups of the target reference signal and the source reference signal, so as to obtain an extended TCI state; sending the extended TCI state and the target reference signal to a user equipment to enable the user equipment to determine a large-scale parameter of each port in the target reference signal. The technical solution of the present invention supports TCI configuration of multi-panel, multi-transmission reference points, and multi-beam communication.
