Abstract

A radio frame or subframe is checked and it is determined to satisfy at least one predefined condition. In response to that determination, a second search space is utilized such that a number Y of blind detections for a user equipment UE in the determined radio frame/subframe is greater than a number X of blind detections for the UE in the radio frame/subframe if a first search space were utilized. In various embodiments the predefined condition is: the number X of blind detections is less than a threshold value Z (Z>=Y) where Z is a maximum number M of blind detections defined by a transmission mode for the frame's/subframe's component carrier CC; a number of CCs configured for the UE; the radio frame or subframe is in the first CC but not in the second CC one of uplink or a special subframe (further conditions) or an almost blank subframe.
