Abstract: Embodiments of the present disclosure provide a method for determining a control channel search space. The method includes: determining numbers of at least two physical resource sets; determining, according to the numbers, location offsets of search spaces corresponding to the at least two physical resource sets, wherein the determined location offsets of the search spaces comprises at least two different location offsets of the search spaces; and determining, according to the location offsets of the search spaces corresponding to the at least two physical sets, the search spaces corresponding to the at least two physical resource sets. By grouping and numbering resources, and determining different location offsets for different search spaces, a probability of control channel search space conflict can be reduced. Thereby, resources of control channels can be maximized in a case of multiple users, and communication efficiency can be improved.
