Abstract: In a method and apparatus for determining a search space, a control resource set of a terminal device is corresponding to at least two aggregation levels. The at least two aggregation levels include a maximum aggregation level and a first aggregation level, the first aggregation level is less than the maximum aggregation level, and the maximum aggregation level is the highest aggregation level of the at least two aggregation levels. Based on the method and the apparatus, a first search space corresponding to the first aggregation level is determined based on a quantity of control channel elements (CCEs) included in the control resource set of the terminal device and the maximum aggregation level.

Abstract: A candidate control channel resource determining method and apparatus are provided. Under the method, a first and a second aggregation level can be determined by a terminal. The aggregation level is a quantity of control channel resource elements in a candidate control channel. The first aggregation level is less than the second aggregation level. Control channel resource elements in a candidate control channel set corresponding to the second aggregation level form a first quantity of candidate control channel sets corresponding to the first aggregation level. One of the first quantity of candidate control channel sets corresponding to the first aggregation level can be determined as a target set based on an identifier of the terminal. A control channel resource element occupied by each candidate control channel in the target set can be determined. A candidate control channel in the target set can be detected for a received signal.
