Abstract:
This application provides example downlink control information transmission methods and apparatuses. In an example method, a terminal device receives first configuration information. The first configuration information may indicate the terminal device to monitor a physical downlink control channel (PDCCH) candidate in a first scheduling cell and a second scheduling cell. The PDCCH candidate is used to carry downlink control information for scheduling data transmission in a same scheduled cell. The terminal device determines, for the same scheduled cell, monitoring upper limits of the PDCCH candidate in a first unit time and a second unit time. The first unit time is determined based on a subcarrier spacing of an active downlink bandwidth part in the first scheduling cell, and the second unit time is determined based on a subcarrier spacing of an active downlink bandwidth part in the second scheduling cell.
