Abstract
This application provides a data transmission method and apparatus, to determine a TCI-state used for data transmission and correctly receive downlink data, thereby improving data transmission efficiency. The method includes: receiving downlink control information (DCI); and if an offset between the DCI and a corresponding physical downlink shared channel (PDSCH) is less than a preset threshold, at least one transmission configuration indicator (TCI) states configured for a serving cell of scheduled PDSCH comprises quasi-co-location (QCL-TypeD) information, and at least one TCI codepoint indicates two TCI states, receiving the corresponding PDSCH by using two default TCI-states corresponding to a smallest codepoint among TCI codepoints indicating two different TCI-states.
