1. A control information transmission method, comprising:
detecting first downlink control information (DCI), in a first specific search space, by a terminal device, wherein
the first DCI indicates an active bandwidth part (BWP) of the terminal device,
the active BWP is used by the terminal device and a network device to transmit a physical data channel,
a size of the first DCI and a size of a second DCI are aligned,
the second DCI can be transmitted in a first common search space,
the second DCI is used to schedule a system message, a paging message, or a random access response (RAR),
the first specific search space is included in a plurality of specific search spaces of the terminal device,
one of the plurality of specific search spaces corresponds to N1 DCI formats, and the plurality of specific search spaces correspond to N2 DCI formats in total, and
sizes of DCI in the N2 DCI formats are aligned in association with the DCI being transmitted in a corresponding specific search space, wherein N1 is an integer greater than or equal to 1, and N2 is an integer greater than or equal to N1.
