Title:
METHOD FOR INDICATING TRANSMISSION CONFIGURATION INDEX STATE, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/088036
Kind Code:
A1
Abstract:
A method for indicating transmission configuration index state, and a device. The method comprises: sending a first message, wherein the first message indicates P transmission configuration index (TCI)-state groups, each TCI-state group in the P TCI-state groups comprises at least one TCI-state, and P is an integer greater than 1; determining a first TCI-state group from the P TCI-state groups, and sending a second message to a terminal apparatus, wherein a TCI field in the second message is used to indicate the first TCI-state group, the P TCI-state groups correspond one-to-one with P TCI field values in the TCI field in the second message, and the first TCI-state group is used for transmission of downlink data to the terminal apparatus.
