Abstract
This application provides a control information transmission method, and relates to the field of wireless communications. The method includes: determining, by a terminal device, whether to monitor an uplink preemption indication (PI) based on whether a time-frequency resource used to transmit uplink data overlaps a reference uplink resource (RUR), to effectively avoid blind detection performed on the uplink PI by terminal devices that do not need to receive the uplink PI, and reduce overheads of blind detection performed on the uplink PI by the terminal devices.
