Abstract

The present disclosure provides a device and a method for determining detection information about search spaces, and relates to the field of communications technology. The method for determining detection information about search spaces includes, in a case that at least two search spaces are being detected by a UE and a sum of initial quantities of pieces of detection information about the at least two search spaces is greater than a total quantity of pieces of detection information supported by the UE, determining a first quantity of pieces of detection information about each of the at least two search spaces. A sum of the first quantities of pieces of detection information about the at least two search spaces is smaller than or equal to the total quantity of pieces of detection information. The detection information includes a PDCCH candidate or PDCCH channel estimate.
