Abstract
An embodiment of this application provides a downlink control information transmission method and an apparatus. The method includes: receiving first downlink control information DCI in search space of a first carrier bandwidth part BWP, where if a frequency domain resource allocation type of the first BWP is a type 0, an Lf-bit frequency domain resource allocation indication in the first DCI is an Lf-bit bitmap, and bits in the Lf-bit bitmap in descending order are respectively corresponding to resource block groups RBG 0 to RBG (Lf−1) in a second BWP; and for one bit in the Lf-bit bitmap, when a value of the bit is t1, an allocated resource includes one RBG corresponding to the bit.
