Title:
DATA TRANSMISSION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/062973
Kind Code:
A1
Abstract:
The present application provides a data transmission method and apparatus. A TCI-state used for data transmission can be determined, and downlink data is correctly received, so as to improve the efficiency of data transmission. The method comprises: receiving a first physical downlink control channel (PDCCH), the first PDCCH being used for scheduling a first physical downlink shared channel (PDSCH); receiving a downlink signal by using a first transmission configuration indication state (TCI-state); obtaining a time interval between the first PDCCH and the first PDSCH; and if the time interval is less than a preset threshold value, obtaining the first PDSCH from the downlink signal.
