地域：
Guangdong
摘要
This application provides a control channel detection method, apparatus, and device. The method includes: A terminal device determines that resources of at least two candidate control channels overlap, where any two of the at least two candidate control channels are located in different search spaces; and the terminal device detects only at least one first candidate control channel in the at least two candidate control channels. This improves control channel detection reliability.

Optionally, each of the at least one first candidate control channel includes a carrier indicator field.
The at least two candidate control channels meet at least one of the following conditions:
-
- only some of the at least two candidate control channels each include a carrier indicator field, or only some of the at least two candidate control channels each do not include a carrier indicator field;
- the at least two candidate control channels include the candidate control channel used for the first downlink control information format and the candidate control channel used for the second downlink control information format: and
- each of the at least two candidate control channels is used for the first downlink control information format.
Optionally, a search space in which the at least one first candidate control channel is located is a second-type search space.
Only some of the at least one first candidate control channel each include a carrier indicator field, or only some of the at least one first candidate control channel each do not include a carrier indicator field.
Optionally, the at least two candidate control channels may meet any one or more of the following conditions:
-
- the search spaces in which the at least two candidate control channels are located are located on a same component carrier or different component carriers;
